Biosimilar Drugs: First Indian Foot Print In An Uncharted Frontier

Posted on by
Reply

A homegrown Indian biologic manufacturer is now about to leave behind its first foot-print, with a ‘made in India’ biosimilar drug, in one of the largest pharma market of the world. This was indeed an uncharted frontier, and a dream to realize for any Indian bio-pharma player.                                                      

On March 28, 2016, by a Press Release, Bengaluru based Biocon Ltd., one of the premier biopharmaceutical companies in India, announced that the Ministry of Health, Labour and Welfare (MHLW) of Japan has approved its biosimilar Insulin Glargine in a prefilled disposable pen. The product is a biosimilar version of Sanofi’s blockbuster insulin brand – ‘Lantus’.

The Company claims that Glargine is a high quality, yet an affordable priced product, as it will reportedly cost around 25 percent less than the original biologic brand – Lantus. This ‘made in India’ biosimilar product is expected to be launched in Japan in the Q1 of 2017. Incidentally, Japan is the second largest Glargine market in the world with a value of US$ 144 Million. Biocon will co-market this product with its partner Fujifilm.

Would it be a free run? 

Although it is a very significant and well-deserved achievement of Biocon, but its entry with this biosimilar drug in Japan’s Lantus market, nevertheless, does not seem to be free from tough competition. This is because, in 2015, both Lilly and Boehringer Ingelheim also obtained Japanese regulatory approval for their respective biosimilar versions of Lantus. In the same year, both these companies also gained regulatory approval from the US-FDA, and the European Medicine Agency (EMA) for their respective products.

Moreover, Sanofi’s longer acting version of Lantus – Lantus XR, or Toujeo, to treat both Type 1 and Type 2 diabetes, has already been approved in Japan, which needs to be injected less, expectedly making it more convenient to patients.

Key barriers to a biosimilar drug's success: 

Such barriers, as I shall briefly outline below, help sustaining monopoly of the original biologic even after patent expiry, discourage investments in innovation in search of biosimilars, and adversely impacts access to effective and much less expensive follow-on-biologics to save patients’ precious lives. 

These barriers can be broadly divided in two categories: 

A. Regulatory barriers:

1. Varying non-proprietary names:

A large number of biosimilar drug manufacturers, including insurers and large pharmacy chains believe, just as various global studies have also indicated that varying non-proprietary names for biosimilars, quite different from the original biologic, as required by the drug regulators in the world’s most regulated pharma markets, such as, the United States, Europe, Japan, and Australia, restrict competition in the market for the original biologic brands. 

However, the innovator companies for biologic drugs hold quite different views. For example, Roche (Genentech), a developer of original biologic, reportedly explained that “distinguishable non-proprietary names are in the best interest of patient safety, because they facilitate Pharmacovigilance, and mitigate inadvertent product substitution.”

Even, many other global companies that develop both original biologic and also biosimilar products such as, Amgen, Pfizer and others, also reportedly support the use of ‘distinguishable nonproprietary names’.

That said, the Biosimilars Council of the Generic Pharmaceutical Association argues that consistent non-proprietary naming will ensure robust market formation that ultimately supports patient access, affordability, Pharmacovigilance systems currently in place and allow for unambiguous prescribing, 

2. Substitution or interchangeable with original biologics:

Besides different ‘non-proprietary names’, but arising primarily out of this issue, automatic substitution or interchangeability is not permitted for biosimilar drugs by the drug regulators in the major pharma markets of the world, such as, the United States, Europe and Japan.

The key argument in favor of interchangeability barrier for biosimilar drugs is the fact that the biological drugs, being large protein molecules, can never be exactly replicated. Hence, automatic substitution of original biologic with biosimilar drugs does not arise. This is mainly due to the safety concern that interchangeability between the biosimilars and the original biologic may increase immunogenicity, giving rise to adverse drug reactions. Hence, it would be risky to allow interchangeability of biosimilar drugs, without generating relevant clinical trial data.

On the other hand, the Generic Pharmaceutical Association (GPhA) and the Biosimilars Council, vehemently argue that a biosimilar drug has a lot many other unique identifying characteristics “including a brand name, company name, a lot number and a National Drug Code (NDC) number that would readily distinguish it from other products that share the same nonproprietary name.”

Further, the interchangeable status for biosimilar drugs would also help its manufacturers to tide over the initial apprehensions on safety and quality of biosimilar drugs, as compared to the original ones.

3. 12-year Data Exclusivity period for biologics in the United states:

Currently, the new law for biologic products in the United States provides 12 years of data exclusivity for a new biologic. This is five years more than what is granted to small molecule drugs. 

Many experts believe that this system would further delay the entry of cost-effective biosimilar drugs, restrict the biosimilar drug manufacturers from relying on the test data submitted to drug regulator by the manufacturers of the original biologic drugs while seeking marketing approval.

A rapidly evolving scenario in the United States:

The regulatory space for approval of biosimilar drugs is still evolving in the Unites States. This is vindicated by the fact that in March 2016, giving a somewhat positive signal to the biosimilar drug manufacturers, the US-FDA released another set of a 15-page draft guidelines on how biosimilar products should be labeled for the US market. Interestingly, it has come just around a year of the first biosimilar drug approval in the United States – Zarxio (filgrastim-sndz) of Novartis.

The US-FDA announcement says that all ‘comments and suggestions regarding this draft document should be submitted within 60 days of publication in the Federal Register of the notice announcing the availability of the draft guidance.’ Besides labeling issues, this draft guidance document, though indicates that the ‘interchangeability’ criteria will be addressed in the future, does not still throw enough light on how exactly to determine ‘interchangeability’ for biosimilar drugs.

That said, these key regulatory barriers are likely to continue, at least in the foreseeable future, for many reasons. The biosimilar drug manufacturers, therefore, would necessarily have to work within the set regulations, as applicable to different markets of the world.

I deliberated a related point in my article of August 25, 2014, titled “Scandalizing Biosimilar Drugs With Safety Concerns” 

B. Prescribers’ skepticism:  

Initial skepticism of the medical profession for biosimilar drugs are, reportedly, due to the high voltage advocacy of the original biologic manufacturers on the ‘documented variability between original biologic and biosimilars. Which is why, any substitution of an original biologic with a related biosimilar drug could lead to increase in avoidable adverse reactions.

‘The medical platform and community QuantiaMD’, released a study just around September 2015, when by a Press Release, Novartis announced the launch of the first biosimilar approved by the US-FDA – Zarxio(TM) (filgrastim-sndz). However, in 2006, Novartis after suing the US-FDA, got the approval for its human growth hormone – Omnitrope, which is a biosimilar of the original biologic of Genentech and Pfizer. At that time a clear regulatory guideline for biosimilar drugs in the United States, was not in place.

The QuantiaMD report at that time said, “Only 12% of prescribing specialists are ‘very confident’ that biosimilars are as safe as the original biologic version of the drug. In addition, a mere 17% said they were ‘very likely’ to prescribe a biosimilar, while 70% admitted they were not sure if they would.” 

Since then, this scenario for biosimilar drugs is changing though gradually, but encouragingly. I shall dwell on that below.

The major growth drivers:

The major growth drivers for biosimilars, especially, in the world’s top pharmaceutical markets are expected to be:

  • Growing pressure to curtail healthcare expenditure
  • Growing demand for biosimilar drugs due to their cost-effectiveness
  • Rising incidences of various life-threatening diseases
  • Increasing number of off-patent biologics
  • Positive outcome in the ongoing clinical trials
  • Rising demand for biosimilars in different therapeutic applications, such as, rheumatoid arthritis and blood disorders. 

This in turn would probably usher in an unprecedented opportunity for the manufacturers of high quality biosimilar drugs, including in India.

Unfolding a huge emerging opportunity with biosimilars: 

This unprecedented opportunity is expected to come mainly from the world’s three largest pharma market, namely the United States, Europe and Japan, due to very high prices of original biologic drugs, and simultaneously to contain rapidly escalating healthcare expenditure by the respective Governments. 

Unlike in the past, when the doctors were apprehensive, and a bit skeptic too, on the use of new biosimilars, some new studies of 2016 indicate a rapid change in that trend. After the launch of the first biosimilar drug in the US, coupled with rapidly increasing incidences of various complex, life-threatening diseases, better knowledge of biosimilar drugs and their cost-effectiveness, doctors are now expressing much lesser concern, and exhibiting greater confidence in the use of biosimilars in their clinical practice.

Yet another, March 2016 study indicates, now only 19.5 percent of respondents feel little or no confidence in the use of biosimilar monoclonal antibodies compared to 61percent of respondents to a previous version of the survey undertaken in 2013 by the same market research group. The survey also shows that 44.4 percent of respondents consider that the original biologic and its biosimilar versions are interchangeable, as compared with only 6 percent in the 2013 survey.

As a result of this emerging trend, some global analysts of high credibility estimate that innovative biologic brands will lose around US$110 billion in sales to their biosimilar versions by 2025.

Another March, 2016 report of IMS Institute for Healthcare Informatics states that lower-cost biosimilar versions of complex biologic, could save the US and Europe’s five top markets as much as US$112 billion by 2020,

These encouraging developments in the global biosimilar arena are expected to encourage the capable Indian biosimilar drug players to invest in this high-tech format of drug development, and reap a rich harvest as the high priced blockbuster biologic brands go off-patent.

Conclusion:

Putting all these developments together, and considering the rapidly emerging scenario in this space, it now appears that challenges ahead for rapid acceptance of biosimilar drugs though are still many, but not insurmountable, at all.

The situation necessitates application of fresh and innovative marketing strategies to gain doctors’ confidence on biosimilar medicines, in total conformance with the regulatory requirements for the same, as they are, in the most important regulated markets of the world.

It goes without saying that success in the generation of enough prescriptions for biosimilar drugs is the fundamental requirement to benefit the patients, which, in turn, would lead to significant savings in health care cost, as estimated above, creating a win-win situation for all, in every way.

As more innovator companies start joining the biosimilar bandwagon, the physicians’ perception on these new varieties of medicines, hopefully, would also change, sooner.

Biocon’s grand announcement of its entry with a ‘made in India’ biosimilar drug in one of the word’s top three pharma markets, would probably be a great encouragement for all other Indian biosimilar drug manufacturers. It clearly showcases the capabilities of an Indian drug manufacturer to chart in an uncharted and a highly complex frontier of medicine.

Ease of Doing Pharma Business in India: A Kaleidoscopic View 

Posted on by
Reply

Ensuring ease of doing any ethical business activity in India, is a new focus area of the Government and is very rightly so. Creating ease of doing ethical pharma business too, falls under this overall national objective.

In this article, restricting myself to the drug sector, I shall deliberate on various aspects, which are now being considered by the pharma industry, related to the ‘ease of doing pharma business in India’. My discussion would cover all subsets of pharma players, irrespective of whether they fall under Multinational (MNC) or purely homegrown Indian companies, with different scales of operations – large, medium, small, or micro. 

To help the Government facilitating the ‘‘ease of doing pharma business in India’, it is just not enough to make the business models for all subsets of the Indian pharma sector looking ethical, conforming to all relevant laws, policies, rules and norms. Each pharma player need also to maintain an ongoing strict internal vigil, religiously, to ensure that the requirements of high quality clinical development, manufacturing and selling practices for effective, safe and rational medicines, are properly understood and strictly followed by all the employees within the organization.

A Kaleidoscopic View:

The above situation is something that ought to happen, as the Government keeps striving to improve the ‘ease of doing pharma business’ in India. However, while looking through a Kaleidoscope, as it were, the colors of industry expectations in this area keep changing rapidly, as the new contentious issues keep emerging. Consequently, the ground reality of assessing the same, by a large section of the pharma players in India, seems to veer only around different types of just self-serving demands, expecting those to act as a powerful tailwind pushing their business interests rapidly forward.

Such expectations keep surfacing, rather frequently, from all the subsets of the pharma industry, be they MNCs and their trade associations or the Companies of purely Indian origin and their trade bodies. The accusation to the Government pertaining to all these issues, is a common one: ‘Where is the ease of doing pharma business in India?’

Citing even some recent incidents, they are voicing with equal gusto, that the root causes of all these problems lie miles outside the pharma industry. The causative factor, they indicate, is rooted at the very doorsteps of the Government, as its ministries initiate tough action to root out corruption in the pharma industry as concurrent measures, disturbing their business comfort zones, and upsetting the apple carts. 

The Government has its task cut out:

I hasten to add that I have no intention to paint it as a confrontation between the Government and the pharma industry, in any way. The Government is also facing the brunt from the various stakeholders, relentlessly, for its utter negligence of public health care, and public expenditure over it.

The impact of this Government indifference, though also comes on the patients, the industry does not seem to have much to crib over it as a direct impediment to the ‘ease of doing pharma business’ in India.

Probably as a diversionary tactic, the industry keeps using this critical Government inaction in the hope of diverting the public, or media attention from its own alleged business malpractices, even at a time when these are being covered both by the national and international media, regularly. Nevertheless, the industry credibility on these issues, seems to have started waning fast, as the genie is out of the bottle.

A common punching bag of all industry dissatisfaction on the Government:

It is worth noting that despite some key differences between the MNC and Indian pharma companies, which I shall discuss later, the common punching bag of the industry dissatisfaction on various Government decisions, always has been the lack of ‘ease of doing pharma business’ in the country.

This discontentment may be well justified. I have no qualms about it. However, when this dissatisfaction gets tagged with some recent Government action, taken to protect public health interests and does not have much to do with the ‘ease of doing ethical pharma business’, many eyebrows are obviously raised.

Against some of these critical patient-centric actions, the industry continues to express its annoyance in unison, while for some other Government decisions, it speaks in different voices – some are happy ones, and the others are not so. However, the common thread of expression of all such dissatisfactions is always linked with the lack of ‘ease of doing business’ in India.

A. Where the pharma Industry in India speaks in unison: 

I shall now give two major examples of the key Government decisions, that have irked the entire pharma industry immensely, and makes it voicing that those Government actions grossly violate the fundamental requirements of its smooth running of business. Is that fair? Let me analyze that below with these two examples:

1. Drug price control:

The industry, by and large, opines that individual drug company should be allowed to decide the way it would price any drug, as the market forces, especially for generic drugs, would determine its price.

Indian Parliament, the Supreme Court of India, the Government in power at different times, most of the independent experts and the NGOs, on the contrary, consider drug price control is necessary in India, especially for essential drugs. It makes high quality essential medicines affordable and accessible to the general population.

National Pharmaceutical Pricing Authority (NPPA) has also announced and explained that the competition does not work on controlling prices for pharma products, where the consumers are not the decision makers. The key prescribing decision makers for the patients are the doctors, who are mostly and unethically influenced by the drug companies having vested interest in making such decisions. This unholy nexus has been widely alleged globally, and also established through umpteen number of studies of high credibility.

Nevertheless, the doctors, from across the globe, including in India, have long disputed that any payments, if and when they receive from pharmaceutical companies, have no relationship to how they prescribe drugs.

A March 17, 2016 study of ProPublica has conclusively established that: “The more money doctors receive from drug and medical device companies, the more brand-name drugs they tend to prescribe. Even a meal can make a difference.” This study may be in the context of the Unites States, but India in this in this regard is no exception, as captured even in the parliamentary Committee reports.

Thus, conceding to high voltage pharma advocacy, made on the pretext of ‘encouraging innovation’ and ‘ease of doing business in India’, if any Government contemplates the abolition of drug price control in India is, it would make not just essential drugs inaccessible to a large section of society, but encourage blatant corrupt practices. This caution has come, besides many others, also from a Parliamentary Committee report, unambiguously. Incidentally, the present Government too strongly speaks against corruption, in any form.

Thus, I reckon, if the industry believes that the price control of essential drugs, which are for public health interest, goes against ease of doing pharma business in India, so be it.

2. Manufacturing and selling of irrational FDCs:

A Fixed Dose Combination (FDC) drug may appear irrational to drug regulators and well-qualified experts, after necessary scientific scrutiny, for various reasons. This may happen, primarily because of the following reasons:

  • When the medical rationale of the FDC along with the ingredient details, submitted to the regulatory authority for marketing approval, are considered scientifically inappropriate.
  • When the evolving medical science establishes the irrationality of the FDC after a period of time.
  • When the analysis of ‘Adverse Drug Event’ reports from the ongoing Pharmacovigilance studies signals a red alert.
  • Widespread uncontrolled misuse or abuse of FDCs, where the consumers’ health risks far outweigh the drug benefits, as provided in the drugs Act, for public health interest.
  • Some regulatory loopholes were misused by the drug manufacturers in the past to get the irrational FDCs approved by the State Drug Authorities, violating the new FDC regulatory approval Policy.

Any irrational FDC so identified by the drug regulators and experts, by putting a system of scrutiny in place, must be banned forthwith, in public health interest. There should not be any scope of negotiation with drug manufacturer to make the bans effective.

Incidentally, realizing the gravity of public health risks posed by irrational FDCs, even the NPPA has reportedly decided to review afresh all new applications for price fixations of FDC and examine their safety and efficacy profile.

Moving towards this direction, the NPPA Chairman, has reportedly sent back more than 200 applications for price fixation of FDCs, instructing the concerned manufacturing and marketing companies to apply again with a declaration that their formulations are not “irrational.” It was also reported that the price regulator has also brought under the lens third-party drug makers and pharma companies that outsource to them, to check illegal sales of irrational FDCs and spurious drugs.

Two key questions being raised now:

Despite all these, the industry keeps repeating, especially, the following two questions, which are worth looking at, one by one: 

1.  Why is the ban now?

I discussed the issue of FDC ban in my previous article in this Blog on March 21, 2016 titled, “The Recent Ban On Irrational FDCs: History Repeats Itself”.

In the above article, I also argued that large section of the industry and its associations are protesting against the Government ban of 344 irrational FDCs, and questioning vigorously, even outside the Delhi High Court – ‘why is the ban now?’

The point ‘why now’ is absolutely irrelevant, as not taking any action ever, against a wrong doing ignored over a long period time for whatever reasons, does not confer any regulatory legitimacy to an irrational FDC formulation to be considered as a rational one for all time to come, and thereby, exposing patients to serious health risks, knowingly.

2.  Why is this ban so sudden, and in some cases after decades?

Sudden banning of drugs, which are in the market for a long time, is not a recent Indian phenomenon in India. In 2011, according to a report, in the world’s largest pharma market – the United States, the FDA banned 500 prescription drugs that had been on the market and working for decades. USFDA ban also happened suddenly, and that includes cough syrups too.  Thus, it is intriguing, why is this fuss created by the Industry in India now? 

In the midst of it, one odd, knee-jerk, apparently ‘spoon-fed’ and ill-informed editorial in some Indian business daily, raises more questions about its real intent, rather than help finding answers to the poorly sketched problems.

I would hope, the Government would stay firm and be able to convince the Delhi High Court today, i.e. on March 28, 2016, with its robust data-based arguments, accordingly.

Be that as it may, in my perspective, if the industry still believes that bans of irrational FDCs to protect public health interest, as decided by the independent experts after long and structured deliberations, would go against ‘ease of doing pharma business’ in India, so be it. 

B. Where the pharma industry in India speaks in different voices:

As stated above, there are several other key areas, where the MNC and Indian Pharma players have sharp differences in their perspectives. Despite these differences, the aggrieved section does not even blink a bit to attribute those Government actions to the lack of ‘ease of doing pharma business’ in the country.

 In this area, I shall give just the following three examples: 

1. The Patents Act:

MNCs say that section 3 (d) of the Indian Patents Act 2005, which is aimed at curbing patent ever-greening or frivolous inventions, is against the ease of doing business in India. However, the Indian Pharma players, do not think so, at all. Similar disagreement also exists in other critical areas too, such as, ‘Data Exclusivity (DE)’ and ‘Compulsory Licensing (CL)’.

Thus, in my opinion, if some ‘public health interest’ related provisions of the robust Indian Intellectual Property (IP) Act, such as, section 3 (d), DE and CL, are considered as going against the ‘ease of doing pharma business in India’ by the MNCs, so be it.

2. Mandatory Uniform Code of Pharma Marketing Practices (UCPMP):

Need to have a mandatory UCPMP, though, is reportedly supported by the MNCs, Indian pharma players do not seem to be quite in sync with this idea. I am not sure, whether the delay in the announcement of mandatory UCPMP, almost in every 3 months, has any coincidence with it or not. However, the reality is, no one still knows clearly, when would it definitely come, if at all.

Media reports on pharma MNC support to mandatory UCPMP, and repeated reiteration that its members in India rigidly follow the IFPMA Code of Marketing Practices, though commendable, seem to grossly lack in credibility.

Interestingly, despite the existence of this code and high-decibel vouch for its rigid conformance, maximum number of MNCs have been fined billions of dollars, by the Government in various countries, for alleged gross marketing and other business malpractices. It has been happening over a long period of time, and is being reported by the international media, frequently.

What is really happening, especially, on the so called total support of ethical marketing practices by the MNCs? Are they trying to create just good optics by craftily framing and supporting such showpiece codes, and blatantly defying these to achieve self-serving goals? The voice gets shriller, even when they are being levied hefty fines, after getting caught red handed, as reported by the global media? I guess, the future would ultimately unfold the reality. But would it, at all?

The Indian Scenario: 

Even in India, such alleged marketing malpractices involving even a top pharma MNC have often been reported by the media. Just to illustrate, “Prescribe a drug maker’s medicine and get a free vacation”, reported a news article. There are several other similar reports too. Hence, the credibility of pharma MNC statements regarding strict conformance to ethical marketing codes, ably formulated by the well-known pharma trade associations, such as, IFPMA, appears to be very low, if exists at all.

The well-reputed medical Journal BMJ in one of its articles titled, “Corruption ruins the doctor-patient relationship in India”, published on May 8, 2014, expressed serious concern on this issue.

It concluded that corruption, kickbacks and the nexus between doctors and pharmaceutical firms are rampant India. This eventually prompted the BMJ, in June 2014, to launch a campaign reportedly called ‘Corruption in Medicine’.

On this issue, way back in May 08, 2012, even the Indian Parliamentary Standing Committee on Health and Family Welfare in its 58th Report, placed before the Parliament on May 08, 2012, expressed its serious concern.

Indian lawmakers, recommended in the report that the Department of Pharmaceuticals (DoP) should take decisive action, without further delay, in making the UCPMP mandatory, so that effective checks could be ensured on ‘huge promotional costs’ and the resultant add-on impact on medicine prices. Unfortunately, despite a change in the Government in 2014, UCPMP has still not been mandatory.

It is anybody’s guess, despite all these reports, what type of external pressure, if at all, the DoP is still facing to put in place a robust mandatory UCPMP with strong deterrent measures.

Under this backdrop, in my view, if mandatory UCPMP having enough teeth, to curb ongoing blatant marketing malpractices to protect patients’ health interest in India, is considered by any as going against the ‘ease of doing pharma business in India’, so be it. 

3. Drug manufacturing quality:

Enough discussions have already been made on import ban of USFDA from over 45 drug manufacturing facilities of Indian Companies, of all sizes and scale of operations, on the ground of drug quality standards. USFDA considered drugs manufactured in those banned facilities are unsafe for the consumption of American patients. Some other foreign drug regulators, from the developed countries, have also taken similar action.

Taking advantage of this development, it was reported that attempts are indirectly being made to establish that MNC marketed generic drugs are superior to similar ones, manufactured even by the large Indian drug producers.

The fact, apparently, is quite different. MNCs operating in India has not come under the USFDA scanner in this regard as much, probably not because of their far superior drug manufacturing quality standards in India, as compared to even the best of their Indian counterparts. I reckon, it is mainly because, very few MNC drug manufacturing facilities in India export India manufactured drugs for consumption in the United States. 

It may not, therefore, make any real sense to conclude that MNC marketed generic drugs in India, either manufactured my themselves or under loan & license or under a third party, are generally better in quality than the similar ones manufactured even by the large Indian manufacturers. 

In any case, I feel that there is a huge scope for Indian drug regulators to ensure uniformly high drug quality standards. This is necessary for Indian patients’ health and safety. There also should be stringent regular quality audits in all drug manufacturing facilities in India, where non-conformance with prescribed standards would attract serious punitive measures. The Union Ministry of Health, together with the State Governments would require increasing the number of auditors accordingly.

However, the reality is, many Indian drug manufacturers have expressed that maintaining stricter drug manufacturing standards (cGMP) would involve huge expenditure, which they will not be able to afford. Consequently, this would go against the ‘ease of doing pharma business’ in India.

Again, in my view, if the stringent regulatory requirements for maintaining high drug manufacturing standards in India to protect public health interest, is considered as going against the ‘ease of doing pharma business’ in India, so be it.

Conclusion:

Improving ‘ease of doing pharma business’ in India is an absolute necessity, just as all other businesses. Pharma sector deserves it very badly too, as it has been experiencing excruciating delay in multiple regulatory clearances. Single window clearances of all applications, with a much greater sense of urgency, without bureaucratic red tapes and avoiding other unnecessary delays, is certainly the way forward for India. It would require urgent policy reforms, maintaining a right balance between, public, consumers and business interests.

Pharma sector is not all villain, either, by any yardstick. It is instrumental in saving and improving the quality of lives of so many people across the globe, since a very long time, with its both innovative and generic medicines. All must acknowledge it, and the Government does it too, openly, several times. 

That said, the space of focus of the pharma industry appears to be getting increasingly narrowed down to more of its self-serving acts, and in their hard selling, through hugely expensive advocacy campaigns, even at the huge cost of attracting frequent self-defeating scathing criticisms, across the world.

At the same time, the Governments in different times hugely disappointed its citizens, in charting a clear road map for quality and affordable health care for all in India, along with appropriate budgetary allocations and policy reforms, and thereafter, in its implantation with military precision.

However, that doesn’t mean, in any way, while facilitating ‘ease of doing pharma business’ in India, the Government would turn a blind eye on the rapidly breeding corruption in the pharma business practices, and give in to unjustified industry muscle-flexing, sacrificing the health interest of its citizens in the country.

While looking through this Kaleidoscope, it appears to me, if the pharma sector considers the appropriate Government actions to protect public health interest, against the unacceptable industry practices, would also go against the ‘ease of doing pharma business’ in India… Well, so be it.

The Recent Ban On Irrational FDCs: History Repeats Itself

Posted on by
Reply

The recent regulatory ban on a large number of irrational Fixed Dose Combination (FDC) drugs is not a new incident in India. A similar mega ban was announced even before, about nine years ago. Intriguingly, the saga continues, for various reasons, without any tangible outcome for the patients on the ground.

On March 11, 2016, the latest ban, again on a large number of irrational FDCs, was notified. It caused a flutter and an immediate sharp adrenaline rush to the impacted drug companies and was soon followed by an interim stay order, again by an honorable High Court of the country.

Thus, when I connect the past dots with the latest one, on mega ban of irrational FDCs in India, a similar sequence of events gets unfolded, following each of such ban notifications of the Government.

Looking back, 294 FDCs were banned by the DCGI in 2007. At that time too, the important issue of patients’ health, safety and economical interest, got converted into a legal quagmire. Many adversely affected FDC drug players chose to go to the court of law to protect their business interest, and also successfully managed to obtain a ‘Stay’ order from the Madras High Court.

Consequently, those 294 irrational FDCs, banned by the Union Ministry of Health on health and safety grounds, continued to be promoted, prescribed and sold to patients across India, without any hindrance, whatsoever.

The matter continues to remain sub judice, as we deliberate the issue here. Thus, whether the recent gazette notification on the ban of irrational FDCs would immediately be implemented, unlike the past ban, or the history would repeat itself, is indeed a big question mark, at this juncture.

Would this ban have similar outcome?  

As discussed, close to a decade after the serious legal fall-out of the ban of 294 irrational FDCs in 2007, another mega ban of 344 irrational FDCs has been announced by the Government, through a Gazette Notification dated March 11, 2016. Some well known brands, such as, Corex, Phensedyl, Crocin Cold and Flu, D-Cold Total, Nasivion and Vicks Action 500 Extra, among others, reportedly come under this ban now. Here is the complete list of 344 banned FDCs.

According to the Government, the reason for banning these drugs is that ‘they involve risk to humans and safer alternatives were available.’

Nevertheless, manufacturers of some of these mega brands have again obtained an interim injunction on the ban for their respective products, from the Delhi High Court.

Sometime during the day, i.e. on March 21, 2016, the honorable Delhi High Court is expected to take up this patient-centric issue. It apparently smacks a blatant self-serving interest of the concerned irrational FDC manufacturers, that defeats the core purpose and value of pharma products for their users.

Like most other issues, the Court directive on this issue, as well, would ultimately prevail, without any shade of doubt.

Is it a ‘bolt from the blue’ for the pharma industry? 

Many industry watchers feel that this recent ban has not come as a ‘bolt from the blue’ for the pharma players, at all, as is being claimed by a section of the pharma industry. Even the Union Ministry of Health has, reportedly, clarified the following points on the recent notification:

  • “We have tried to bring objectivity to the issue by roping in the best of scientists to study the effects of these FDCs.”
  • “Show cause notices were also issued to more than 344 companies and they were given time to make further representations after the expert committee gave their recommendations. Some of them did not even care to respond. Everybody was given ample opportunity. After that, the move was initiated. It was done after much examination.”
  • “It is necessary and expedient in the public interest to regulate by way of prohibition of manufacture for sale, sale and distribution for human use, of the said drugs in the country.”

It is worth noting, at least, one of these well known pharma brands was, reportedly, banned in one of our neighboring countries – Sri Lanka, in 2012, for wide-spread drug misuse, long after its marketing approval in the country.

Some key events leading to the recent ban: 

Besides the above articulation by the Union Ministry of Health, it is worth noting, especially, the following key developments to ascertain, whether this ban came suddenly to the irrational FDC manufacturers, and without any prior warning or appropriate communication:

  • The issue of manufacturing licenses being granted by some states for FDCs without prior approval of Central Drugs Standard Control Organization (CDSCO), was first discussed by the Drugs Technical Advisory Board (DTAB) in the year 2000, though without any major tangible outcome till 2007. 
  • In 2007, Government banned 294 FDCs, and the consequent court proceedings had ‘Stayed’ this ban.
  • Expressing huge concern on pharma malpractices related to irrational FDCs, the Parliamentary Standing Committee on Health and Family Welfare in its 59th report (2012) also had flagged this issue. The lawmakers observed in the report that manufacturing licenses for large numbers FDCs were being issued by the State Drug Authorities, without prior approval of the Central Drugs Standard Control Organization (CDSCO), in violation of rules. The committee also noted that multiple FDCs, which are available in India had been rejected by the drug regulators in Europe, North America, and Australia, while for many others never had marketing approval applications submitted outside India (Section 7 of [6]).
  • Subsequently, in June 2013, CDSCO  announced the “Policy Guidelines for Approval of Fixed Dose Combinations (FDCs) In India.”
  • According to CDSCO, just 1193 FDCs were approved by the DCGI, since 1961 till November, 2014. Thus, all drug manufacturers should clearly know, which FDC has been approved by the DCGI, and when, leaving no scope for any ambiguity in this area. Thus, there should be no problem in total conformance to the above ‘FDC Policy Guidelines’ by these drug producers.
  • In the same year – 2013, a public notice was also, reportedly, issued, calling all those drug players manufacturing FDCs to apply with the requisite fee, in the prescribed form to the DCGI office, providing the required details.  
  • In 2014, a six-member committee, chaired by Prof. (Dr.) Chandrakant Kokate, Vice Chancellor, KLE University, Jawaharlal Nehru Medical College, Belgaum, Karnataka, was formed to expedite the review process of the applications. 
  • The Kokate Committee has, reportedly, reviewed about 6,600 FDCs, so far, and classified them under four categories – irrational, require further deliberations, rational and require additional data generation. 
  • According to a report, 963 FDCs were found under the irrational category, providing reasons in detail for each. 
  • In 2016, the Government finalized its action, based on the Report of Kokate Committee and also the response received (or still not received despite requests) from the concerned FDC manufacturers.
  • The March 11, 2016 Gazette Notification banned 344 ‘irrational’ FDCs, ruffling many feathers, but understandably to protect patients’ health interest.
  • On March 14, 2016, in response to an appeal against this ban through a writ petition, first by Pfizer, the Delhi High Court reportedly granted the company a stay, pending the next court hearing on March 21, 2016. Subsequently, several such stay orders by the honorable Delhi High Court have been issued with the same date of hearing. 
Adverse health and economic impact on patients:

Besides serious health risks, the patients also suffer from a huge adverse economical impact, in rupee value terms, by consuming much avoidable irrational FDC formulations, which are generally more expensive than single ingredient drugs, if taken separately at times of necessity or convenience.

The ban of 344 FDCs is estimated to cover over 2,500 brands, in different therapy categories, including chronic diseases, where medicines are taken for a long period of time. Thus, a large number of patients were consuming these irrational formulations for a long period of time without any inkling of their necessity and more importantly serious adverse health impact that these irrational FDCs could cause.

To quantify how much have the patients collectively spent on these banned medicines, in the rupee value terms, I shall quote from the estimates of one of the well reputed and much quoted pharma retail audit and market research organization of India – AIOCD Pharmasofttech AWACS Pvt. Ltd.

According to its report of March 13, 2016, Indian Pharmaceutical Industry would lose Rs. 3,838 Crore (MAT), which is 3.1 percent of the turnover of the Indian Pharmaceutical Market (IPM), when calculated based on the retail sales of these FDCs in the last 12-month period.

Paraphrasing the same finding, one can logically conclude that Indian patients withstood an adverse economic impact of Rs. 3,838 Crore in a 12-month period, by spending on these unnecessary and irrational FDCs of dubious value, besides health risks. 

To my surprise, some of the MNC pharma players contribute a major chunk to this avoidable expenditure of the patients, besides associating and avoidable health risks.

Quoting similar credible data, it is also possible to give company-wise break-up in this area, which, in my view, may not be meaningful here.

Two Critical issues to address:

Although, a lot of water has since flown down the bridges, a large number of irrational FDCs are still in the market, exposing patients to possible health hazards and economical hardship.

In this blog, I discussed this core issue in two of my articles, one on July 15, 2013 titled, “FDC Saga: Defiant Manufacturers, Sloppy Regulators and Humongous Inaction”, and the other on May 18, 2015 titled, “Booming Sales Of Unapproved Drugs: Do We Need ‘Safe In India’ Campaign For Medicines?”.

I reckon, the following two would still remain the critical issues, which need to be addressed, expeditiously, once and for all, for patients’ sake: 

  • Stringent compliance with the latest CDSCO requirements by all the manufacturers of FDCs in India must be ensured. Any non-conformance should attract strong punitive measures, through a transparent process.
  • Whether such drugs are being widely misused, creating a grave risk for health and other safety hazards, must be ascertained periodically, based on credible data.
An important example:                         

Just the other day, Reuters reported that one of the largest pharma companies operating in India, was selling a FDC of the antibiotics cefixime and azithromycin, without approval of the DCGI.

Interestingly, this particular FDC has reportedly not received marketing approval in the major global pharma markets, such as, the United States, the United Kingdom, Germany, France or Japan.

After the ban of this irrational FDC, the company was compelled to stop manufacturing and sales of this powerful antibiotic cocktail that poses huge health risk to patients.

This Reuters report also states, the drug ‘had been promoted and administered as a treatment for a broad array of illnesses, including colds, fevers, urinary tract infections, drug-resistant typhoid and sexually transmitted diseases.’ It also found chemists who were selling the drug to prevent post-operative infection and for respiratory problems.

Many doctors and health experts have been saying that the spread and misuse of antibiotic combinations may be contributing to antibiotic resistance in India.

FDC approval must be hard evidence-based:

Since all pharmaceutical products, whether available as a single ingredient, or FDC formulations, are globally considered as ‘Evidence-Based Medicines’. Such evidences are established through robust, stringent and well regulated clinical trials for obtaining marketing approval from the drug regulators, unlike most ‘traditional medicines’.

Following this well-established global norm, and as recommended by even the World Health Organization (WHO), all irrational FDCs must be identified through a transparent and medical science-based process, and banned forthwith by the Government.

Establishing safety and efficacy for all FDCs through clinical trials, just like any other single ingredient drug, introduced for the first time in India, whenever it happens or had happened in the past, inadvertently or otherwise, should be a ‘must happen’ regulatory requirement, for all time to come.

Profit making interest through introduction of a plethora of irrational FDCs, should never be allowed to overshadow patients’ health and economical interest.

The bogey of even ‘25 to 30-year-old FDCs’ now being banned: 

Some section of the industry is also raising this point, vociferously, protesting against the bans of their respective old and top-selling FDC brands, which have now been considered by the Government as irrational, and questioning: ‘why now?’

This point is irrelevant, as not taking action ever, against a wrong doing allowed over a long period time, does not make an irrational FDC formulation a rational one, for all time to come.

Moreover, this recent action of the drug regulator can not be considered as unique either. With the advancement of medical science, in the past years too, the DCGI issued banned notifications, covering many old FDCs, considering those ‘irrational combinations’ at a given point of time, such as, analgin + pitofenone, vitamins B1 + B6 + B12, cyproheptadine + lysine, just to name a few.

Conclusion:

As is known to many, pharmacovigilance is still at a very nascent stage in India. Consequently, ‘Adverse Drug Reactions (ADR)’ or ‘Adverse Drug Events’ reporting are still abysmally poor in the country. No information on ‘Adverse Drug Events’, as claimed by the manufacturers of these irrational FDCs, should, therefore, in no way mean that these drugs are safe and efficacious and beyond any reasonable doubt.

Although the laxity of the drug regulator in this area can’t also be condoned, in any way, the enormity of the risks posed by irrational FDCs to the innocent patients, is indeed mind boggling.

If the manufacturing and sale of all irrational FDCs are not legally stopped, even after a long and rigorous scientific and medical scrutiny by the experts, the patients in the country would, unfairly, continue to remain exposed to huge health and economic risks, without any fault of theirs. This is exactly what happened in 2007 also, when, after the stay order of the ban notification for 294 irrational FDCs by the honorable Madras High Court, all those FDCs continued to be promoted, prescribed and sold to patients across India, unhindered… but at whose cost?

Yet again, the gazette notification of the Government on the recent ban on 344 FDCs, has gone for judicial scrutiny, at least, for some money spinning key brands of the large pharma players.

This time, however, there is one significant difference, the Government seems to be far more assertive and committed to ensure that only safe medicines are available in the market, despite reported intense advocacy by the industry. This commitment on the part of the Government is also evident from the media report that the (DGCI) has again sent a new list of additional 1,200 FDCs for a probe to the panel, which recommended the ban of 344 irrational FDCs in the last week, and that too, after the court stay order on the latest ban.

Further, a senior a senior official in the Health Ministry has, reportedly, reiterated that the Government will stand firm on its decision, and will support the ban with robust data, in the Delhi High Court.

Would history repeat itself, this time now? We, at least, would get a sense of it, as the proceeding of the honorable Delhi High Court commences today, on this issue.

Either way, it will possibly send a clear signal, whether the triumph of commercial profit motive with irrational FDCs would continue, unabated, over patients’ health, safety and economic interests, at least in the foreseeable future.

The Curious Conundrum of New Drugs Approval Process

Posted on by
Reply

Fathoming the details of just a short span of time, not going beyond the last 10 years, I find from the published data that many new drugs, such as, Alatrofloxacin, Aprotinin, Drotrecogin alfa, Lumiracoxib, Propoxyphene, Rofecoxib, Rosiglitazone, Sibutramine, Tegaserod, Tetrazepam, were withdrawn from a number of important global markets. Quite a few of those were withdrawn also from the world market.

The key reason for almost all these withdrawals was serious safety concerns for the patients while using these medicines. Interestingly, some of these new molecules were withdrawn even after attaining the blockbuster status, such as Rofecoxib.

Tens of thousands of patients have died only because of this reason, according to reports.

It is widely believed by the experts in this area, if full public disclosure of the entire data of drug clinical trials was made, most of these new drugs would not have seen the light of the day and without putting many patients’ health safety in jeopardy.

All this is a part of a curious conundrum in the new drug approval process, across the world, for various reasons. In this article, I would try to dwell on this issue.

Voices against this ‘unethical practice’ getting louder:                                             

On December 22, 2015, ‘CBC News’ published an interesting article, titled “Researcher issues ‘call to action’ to force release of hidden drug safety data: Bringing drug industry data into the light of public scrutiny.”

The article echoed the same belief of other global experts and, in fact, went a step forward. It categorically reiterated, if full disclosure of the entire data of drug clinical trials is made public, medical practice might have been quite different.

To drive home this point, the article cited the example of the arthritis drug rofecoxib (Vioxx), which has been linked to tens of thousands of deaths related to heart attacks.

It highlighted, although this risk was very much known to the regulatory authority of the United States, the relevant data was not released to the public for an impartial scrutiny.

Quoting different sources, the paper observed, almost half of the drug trials remain secret and the studies that are published, overwhelmingly report results that make the drug in question look good.

Independent experts’ views differed from the innovator companies:

In some cases, when researchers were able to see what is hiding in the filing cabinets of the drug innovator companies, a different picture altogether emerged on the overall profile of those drugs.

One group looked at 12 antidepressants, comparing the published studies with the internal US FDA assessments. They found that 94 per cent of the published studies were positive, as compared to 51 per cent, when they included all of the studies assessed by the drug regulator.

Based on a detailed study, the authors concluded, without considering all the data, drug effectiveness can often be exaggerated, leading doctors and patients to assume that the medications work better than what they actually do. The ongoing practice of the drug players may help them to significantly diminish the risks, related to the benefits offered by these medicines.

A few months ago, another group analyzed the data from an unpublished drug company study about the effect of Paxil on teen depression and found that the drug did not work and was not safe for the patients. This result completely contradicted the original, unpublished study on this drug.

A crusader emerged in Canada:

Interestingly, the same article, as above, states that Mathew Herder , the health law associate professor at Dalhousie University in Halifax, Canada is now taking up the fight. He is now “calling on other doctors, researchers and journalists to bombard Ottawa with their own demands for drug industry data, using the new legislative lever called the ‘Protecting Canadians from Unsafe Drugs Act,’, which was passed late last year in Canada. 

He has also created a template to help doctors, researchers and journalists access drug safety data at Health Canada. Herder reportedly could even include biomedical researchers, doctors who prescribe medicine, investigative journalists pursuing questions about drug safety, and other activists and patient groups.

This example is worth imbibing elsewhere.

The ‘Rule Books’ are in place, though with loopholes:

To curb such alleged patient unfriendly practices of the innovative drug manufacturers, while obtaining the marketing approval of new drugs, various rules and procedure were put in place, by various authorities.

I shall deliberate below a few of these rules, and enough loopholes therein, enabling the interested parties to hoodwink the external experts, at the cost of patients.

International Clinical Trials Registry Platform:

Much before Herder, following a ministerial summit on Health Research in 2004, a World Health Assembly Resolution passed in 2005 called for unambiguous identification of all interventional clinical trials. This resolution led to the establishment of the ‘World Health Organization (WHO) International Clinical Trials Registry Platform’. It collates information on trials that have been notified in a network of clinical trial registries.

According to W.H.O, “The registration of all interventional trials is a scientific, ethical and moral responsibility”.

In the latest version of the Declaration of Helsinki, it reiterates, “Every research study involving human subjects must be registered in a publicly accessible database before recruitment of the first subject.”

It unambiguously states, “Researchers have a duty to make publicly available the results of their research …. Negative and inconclusive as well as positive results must be published or otherwise made publicly available”.

Understandably, W.H.O statement underscores, “There is an ethical imperative to report the results of all clinical trials, including those of unreported trials conducted in the past.”

It is worth mentioning here that on January 1, 2015, by a new policy on publication of clinical data, ‘European Medicines Agency (EMA)’ also decided to proactively publish all clinical reports submitted as part of marketing-authorization applications for human medicines, by the by pharmaceutical companies.

Big Pharma's serious apprehensions on greater Public transparency:  

Before finalization of the above policy, EMA sought comments on its draft from various state holders. On September 5, 2013, in its remarks on the draft, ‘The European Federation of Pharmaceutical Industries and Associations, EFPIA’ expressed its apprehension about the public health safety oriented proactive move by the EMA as follows:

“We are worried by a move towards greater transparency of clinical trials data that appears to be putting transparency – at whatever cost – ahead of public health interests. Our detailed response to the EMA draft policy speaks to this concern. While EFPIA values other voices and opinion in the conversation surrounding clinical trials data, we believe there are better alternatives than what the EMA is presenting.” 

This is of course understandable. That said, it also gives satisfaction to note that EMA did not wilt under any pressure on this score, whatever the anecdotal might of the external force be. 

Gross non-compliance, endangering patients’ health safety:

Although, the standards and requirements of “Public Disclosure of Clinical Trial Results” have been well specified now, and even in most of the Big Pharma websites one can find disclosure norms of clinical trial data, their overall compliance on the ground, is still grossly inadequate, endangering patients’ health safety.

An article published in the BMJ Open on November 12, 2015 titled, “Clinical trial registration, reporting, publication and FDAAA compliance: a cross-sectional analysis and ranking of new drugs approved by the FDA in 2012”, well captured the magnitude of this issue. 

Nevertheless, the study analyzed just a subset of drugs approved in a single year, 2012. The researchers only examined whether clinical trials were registered and reported, not what that data suggested about how the drugs worked.

The paper reported the results as follows:

“In 2012, the US FDA approved 39 novel new medicines, known as NMEs, and 35 novel drugs. Combining these lists, the FDA approved a total of 48 new drug entities, 15 of which were sponsored by 10 large pharmaceutical or biotechnology companies with market capitalizations valued over US$19 billion. A total of 342 trials were conducted to gain regulatory approval of the 15 drugs, 24 of which were excluded from our analysis, leaving 318 trials involving 99 599 participants relevant to our study, a median of 17 trials per drug.”

Based on the findings, the authors concluded asunder:

“Trial disclosures for new drugs remain below legal and ethical standards, with wide variation in practices among drugs and their sponsors. Best practices are emerging. 2 of our 10 reviewed companies disclosed all trials and complied with legal disclosure requirements for their 2012 approved drugs. Ranking new drugs on transparency criteria may improve compliance with legal and ethical standards and the quality of medical knowledge.”

Simultaneously, The Washington Post in an article of November 12, 2015, titled, “How pharma keeps a trove of drug trials out of public view”, summarized this report by highlighting to the general public that one third of the clinical trial results that US FDA reviewed to approve drugs made by large pharmaceutical companies in 2012, were never publicly reported. 

Unethical practices skewing medical science:

On July 25, 2015, ‘The Economist’ published an article titled, “Spilling the beans’. It highlighted again that the failure to publish the results of all clinical trials is skewing medical science. 

This article also brought to the public attention that half of the clinical trial results are never published over several decades. It broadened the discourse with the observation that this specific unwanted practice, distorts perceptions of the efficacy of not just drugs, but devices and even surgical procedures too, in a well planned and a systematic manner. What is most important to note is, it has seriously compromised with patients’ health interest, across the world. 

It keeps on happening, as there are no firm obligations on the part of drug companies for making public disclosure of all such data, both for and against, though all these data are required to be filed with the regulatory authorities. Hence, the overall assessment of the drugs, weighing all pros and cons, is just not possible for any outside expert agency.

For granting necessary marketing approval, the designated authorities, at least theoretically, ensure that the drugs are reasonably safe, and have, at least, ‘some beneficial effects’. However, the prescribing doctors would continue to remain ignorant of the untold facts, the article states. 

According to ‘The Economist’, although in the United States the relevant laws were modified, way back in 2007, to address this issue, it still remains as a theory, the actual practices in this regard are mostly not so.

Despite vindication no tangible outcome yet:

As I said earlier, this fact got vindicated through extensive research by the ‘BMJ Online’ article and many other contemporary medical publications. 

For example, the evidence released earlier on  April 10,  2014 by the Cochrane Collaboration of London, UK, also shows that a large part of negative data generated from the clinical trials of various drugs were not disclosed to the public. 

Again, like Vioxx, though the US FDA was aware of all such data, for a well known drug Tamiflu, unfortunately the prescribing doctors were not. As a result, the U.S. Centers for Disease Control and Prevention (CDC), which doesn’t have the same access to unpublished data as the regulators, recommended this medicine not being able to evaluate it holistically. 

However, as the findings from the unpublished clinical trials eventually surfaced, CDC expressed serious apprehension on the overall efficacy of Tamiflu, quite contrary to the assessment of the concerned big pharma player.

Hence, despite quite a large number of vindications by the experts, no tangible outcome has been noticed on this pressing issue, just yet.                                                                

Conclusion:

Based on all this discussion, the moot question that springs up: Why do the doctors still prescribe such drugs, even after being aware of the full facts?

In this regard, an article titled, “Big Pharma Plays Hide-The-Ball with Data”, published in the Newsweek on November 13, 2014 raised a very valid question. 

It commented, even if Tamiflu does nothing, and there is just a slight chance of life-threatening side effects, why was it approved by the US FDA, in the first place?

Even more intriguing is: Why do the doctors continue prescribing these, especially after the Cochrane Collaboration took the Tamiflu’s maker, Roche, to task about many of its claims, in April 2014.

Incidentally, the Cochrane Collaboration is widely regarded as one of the most rigorous reviewers of health science data. It takes results of multiple trials, looks for faults and draws conclusions. It doesn’t accept funding from businesses with a stake in its findings.

The answer to this question may perhaps be too obvious to merit any elaborate discussion here. 

Be that as it may, this curious conundrum of ‘New Drug Approval’ with ‘Partial Public Disclosure of Clinical Trial Data’ needs to effectively addressed, without further delay. If not, patients’ health interest would continue to get seriously compromised with the continuation of prevailing laxity in its implementation process by the drug regulators.

Nutraceuticals: A Major Regulatory Step That Was Long Overdue

Posted on by
Reply

Currently in India the nutraceutical products segment, with surrogate or off-label therapeutic claims, is growing at a reasonable pace.

Many such products are now being directly promoted to the medical profession, just like any other modern medicines, with therapeutic claims not being supported by robust clinical data that can pass through scientific or regulatory scrutiny.

For such use of nutraceutical products, I raised the following two questions in my article on this Blog titled, “Nutraceuticals with Therapeutic Claims: A Vulnerable Growing Bubble Protected by Faith and Hope of Patients” on August 27, 2012: 

  • What happens when the nutraceutical products fail to live up to the tall claims made by the respective manufacturers on their efficacy and safety profile?
  • Are these substances safe in those conditions, even when not enough scientific data has been generated on their long term toxicity profile?

Importance of robust clinical data for any product with therapeutic claims:

For similar claim of therapeutic efficacy in the treatment of a disease condition, any drug would require establishing its pharmacokinetics and pharmacodynamics with pre-clinical and clinical studies, as stipulated by the drug regulators. Some experts believe that these studies are very important for nutraceutical products as well, especially when therapeutic claims are made on them, directly or indirectly. This also because, these substances are involved in a series of reactions within the body. 

Similarly, to establish any long term toxicity problem with such products, generation of credible clinical data, including those with animal reaction to the products, both short and long term, using test doses several times higher than the recommended ones, is critical. These are not usually followed for nutraceutical products in India, even when therapeutic claims are being made.

Some experts in this field, therefore, quite often say, “A lack of reported toxicity problems with any nutraceutical should not be interpreted as evidence of safety.” 

The current status:

Currently in India, nutraceuticals, herbals and functional foods are covered under the definition of ‘food’ as per Section 22 of Food Safety & Standards Act, 2006. These food products have been categorized as Non-Standardized/special food products. Neither was there any properly framed guidelines related to manufacturing, storage, packaging & labeling, distribution, sales, claims and imports, nor any legal fear of counterfeiting.

A recent reiteration of the need of regulatory guidelines for nutraceuticals:

In a study on ‘Indian Nutraceuticals, Herbals, and Functional Foods Industry: Emerging on Global Map,’ jointly conducted by The Associated Chambers of Commerce and Industry of India (ASSOCHAM) and RNCOS and released by ASSOCHAM on August 17, 2015 the above key apprehensions on the lack of any kind of regulatory guidelines for the approval and monitoring of products falling under this segment, were reiterated.

The market:

According to the above study, the global nutraceuticals market is expected to cross US$ 262.9 billion by 2020 from the current level of US$ 182.6 billion growing at a compound annual growth rate (CAGR) of about 8 percent.

United States (US) has the largest market for the nutraceuticals, followed by Asia-Pacific and European Union. Functional food is the fastest growing segment in the US nutraceuticals market. Germany, France, UK and Italy are the major markets in the European Union for nutraceuticals. Japan (14 percent) is the major consumer of nutraceuticals in Asia-Pacific, followed by China (10 percent).

The Indian nutraceuticals market is at a nascent stage now, but fast emerging. India accounts for around 1.5 percent of the global market. However, the above study forecasts that due to rising awareness of health and fitness and changing lifestyle, India’s Nutraceuticals market is likely to cross US$ 6.1 billion by 2020 from the current level of US$ 2.8 billion, growing at a compound annual growth rate (CAGR) of about 17 percent. 

Phytochemicals in nutraceuticals:

Phytochemicals have been broadly defined as chemical compounds occurring naturally in plants. A large number of phytochemicals, either alone and/or in combination, are currently being used as nutraceuticals with significant impact on the health care system, claiming a number of medical health benefits, including prevention, treatment and even cure of many types of diseases.

The most recent regulatory intervention:

Responding to the growing demand for regulatory intervention in this important matter, on November 30, 2015, by a gazette notification, the Government of India included phytopharmaceutical drugs under a separate definition in the Drugs & Cosmetics (Eighth Amendment) Rules, 2015, effective that date.

This regulatory action also followed the rapidly growing use of these drugs in India, which includes purified and standardized fraction with defined minimum four bio-active or phytochemical compounds. 

On the ground, this significant regulatory measure would necessarily require the pharma players to submit the specified data on the phytopharmaceutical drug, along with the application to conduct clinical trial or import or manufacture in the country.

The salient features of the notification:

I am summarizing below, only the salient features of the detail notification for obtaining regulatory approval of these drugs in India:

A. Data to be submitted by the applicant:

A brief description or summary of the phytopharmaceutical drug giving the botanical name of the plant: 

- Formulation and route of administration, dosages

- Therapeutic class for which it is indicated

- The claims to be made for the phytopharmaceutical product.

- Published literature including information on plant or product or phytopharmaceutical drug, as a traditional medicine or as an ethno medicine and provide reference to books and other documents, regarding composition, process prescribed, dose or method of usage, proportion of the active ingredients in such traditional preparations per dose or per day’s consumption and uses.

- Information on any contraindications, side effects mentioned in traditional medicine or ethno medicine literature or reports on current usage of the formulation.

- Published scientific reports in respect of safety and pharmacological studies relevant for the phytopharmaceutical drug intended to be marketed.

- Information on any contraindications, side effects mentioned or reported in any of the studies, information on side effects and adverse reactions reported during current usage of the phytopharmaceutical in the last three years, wherever applicable.

- Present usage of the phytopharmaceutical drug ,  –  to establish history of usages, provide details of the product, manufacturer, quantum sold, extent of exposure on human population and number of years for which the product is being sold. 

B. Human or clinical pharmacology information

C. Identification, authentication and source of plant used for extraction and fractionation

D. Process for extraction and subsequent fractionation and purification

E. Formulation of phytopharmaceutical drug applied for

F. Manufacturing process of formulation

G. Stability data

H. Safety and pharmacological information

I. Human studies

J. Confirmatory clinical trials

K. Regulatory status in other countries

L. Marketing information, including text of package inserts, labels and cartons

M. Post marketing surveillance (PMS)

N. Any other relevant information that will help in scientific evaluation of the application

Conclusion:

Prior to the above gazette notification, companies marketing nutraceutical products in general and phytochemical products, in particular, used to operate under a very relaxed regulatory framework.

Such products are currently promoted with inadequate disclosure of science based information, particularly with the surrogate therapeutic claims, which are based merely on anecdotal evidence and forms a part of intensive off-label sales and marketing efforts on the part of respective marketing players. It continues to happen, despite the fact that off-label therapeutic claims for any product are illegal in India, just like in many other countries.

Appropriate measures now being taken by the Government on phytochemical drugs, are expected to further plug the regulatory loopholes for off-label therapeutic claims without any robust scientific evidence. This particular regulation would also, hopefully, help curbing marketing malpractices to boost sales turnover of such products.

Considering all this, it appears that this is a major regulatory step taken by the Indian Government that was, in fact, very long overdue. Implemented properly, this would ensure predictable health outcomes and improved safety standards for most of the nutraceutical products, solely keeping patients’ health interest in mind.

Marketing Off-label Use of Drugs: A Path Much Abused?

Posted on by
Reply

As many would know, prescribing any medicine for disease conditions that are not approved by the drug approving authorities while granting its marketing approval, is generally termed as ‘off-label’ use of drugs.

It is also a usual practice in most of the regulated markets of the world that once the drug regulators give marketing approval of a medicine, which is indication-specific, physicians are free to prescribe these as they deem necessary. However, the drug manufacturers can seek prescription support from the doctors only for the indications as approved by the appropriate government authorities.

Even the USFDA had articulated, “the best way to address any concerns that the information about those (off-label) uses is not reaching medical practitioners is to get those uses in the labeling. We believe that the risks of allowing drug companies to distribute journal articles and other information about off label uses far outweigh any benefits.”        

Since long, most of the drug regulators across the world, including the Drug Controller General of India (DCGI) have prohibited the sales promotion for unapproved uses of drugs to doctors. Nevertheless, the practice continues ignoring its serious consequences.

Monitoring of ‘off-label’ use is challenging: 

Monitoring of off-label use of medicines is quite challenging too by the drug regulators, especially in India, where post marketing surveillance is generally just on paper.

In this regard, a recent research study that I shall refer to below in this article, has quite appropriately suggested, “Future electronic health records should be designed to enable post market surveillance of treatment indications and treatment outcomes to monitor the safety of on and off-label uses of drugs.”

As India intends to move towards the ‘Digital’ space, this suggestion would be quite implementable by the DCGI, as the ‘Smart Cities’ start coming up.

Some examples of extensive off-label usages: 

According to the study done by a team of experts in medical information – Iodine, using the top drugs by number of monthly prescriptions, the following is a list of 4 medications with surprising off-label uses:

Drug Approved Indication Off-label Indication
Abilify (Aripiprazole) Schizophrenia, Bipolar Disorder, Major Depressive Disorder (adjunctive), Autism-related Irritability, Agitation associated with Schizophrenia or Bipolar Mania, other Insomnia
Lyrica (Pregabalin) Management of: neuropathic pain associated with diabetic peripheral neuropathy, post herpetic neuralgia, fibromyalgia, neuropathic pain associated with spinal cord injury; adult patients with partial onset seizures (adjunctive) Anxiety
Namenda (Memantine) Moderate to severe dementia of the Alzheimer’s type ADHD, OCD
Synthroid (Levothyroxine) Low thyroid hormone levels, some types of goiters, management some types of thyroid cancers Depression

Off-label use and increasing risks of drug safety: 

In its November 02, 2015 online issue, JAMA Internal Medicine published an article titled, “Association of Off-Label Drug Use and Adverse Drug Events (ADE) in an Adult Population.” The objective of this study was to monitor and evaluate off-label use of prescription drugs and its effect on ADEs in an adult population.

This particular study assumes importance, as off-label use of prescription drugs without strong scientific evidence has been identified as an important contributor to preventable Adverse Drug Events (ADEs), especially in children. However, despite concerns in this regard, no systematic investigation on the effects of off-label drug use in adult populations is being performed, regularly.

The detail analysis of this study reveals that not only is the benefit of off-label prescription is uncertain, but the risks of ADEs could make the ‘risk-benefit ratio’ quite unfavorable. So much so that in a large number of cases, no drug treatment will be a much better option.

According to the authors, the risk for ADEs grew as the number of prescription drugs the patient used increased. For example, patients using eight or more drugs had more than a 5-fold increased risk for ADEs compared with patients who used one to two drugs.

The study involving 46,021 adult patients, receiving 151,305 prescriptions between January 2005 and December 2009 was done in Canada. Of those prescriptions, more than 10 percent were prescribed for off-label use. Interestingly, out of that group, more than 80 percent prescriptions were for off-label uses without any robust scientific evidence supporting the use.

Based on the findings the researchers concluded that off-label use of prescription drugs is associated with ADEs.

The article suggested:

  • Caution should be exercised in prescribing drugs for off-label uses that lack strong scientific evidence.
  • Future electronic health records should be designed to enable post market surveillance of treatment indications and treatment outcomes to monitor the safety of on and off-label uses of drugs.

Pharma industry strongly opposes off-label use, when it suits them:

Interestingly, pharma industry vehemently opposes off-label use of drugs, when it suits them.

To give just a couple of examples, recently a new law that permits prescribing of drugs for off-label uses in France has reportedly been strongly opposed by the pharmaceutical industry in Europe.

Pharma trade associations argue, “the above move of France is directly in opposition to European Union’s laws that prohibit member states from supporting off-label use for economic purposes, and is a trend that undermines the current regulatory framework and could put patients’ health at risk.”

Besides France, they have also submitted a complaint against Italy to the European Commission over the country’s new off-label rules.

Common methods followed for off-label marketing:

The other side of the story is that, reportedly many pharma companies continue promoting off-label uses of drugs aggressively, for significant commercial gains.

According to ‘The Centers for Medicare & Medicaid Services (CMS) – a federal agency within the United States Department of Health and Human Services, some of the off-label drug promotion methods of the pharmaceutical companies are as follows:

• Paying incentives to sales representatives based on sales for off-label use

• Paying kickbacks to physicians to prescribe drugs for off-label use

• Disseminating misleading posters promoting off-label use

• Paying physicians:

- To pretend to be the authors of articles about off-label uses when the articles were actually written by manufacturers’ agents

- To serve as members of “advisory boards” promoting off-label use

- To travel to resort locations to listen to promotions about off-label use

- To give promotional lectures in favor of off-label use to fellow practitioners

• Publicizing studies showing efficacy of off-label uses, while suppressing studies showing no efficacy.

Even the Uniform Code of Pharmaceutical Marketing Practices (UCPMP) of the Government of India does not allow such sales and marketing practices. But these all continue to happen, unabatedly.

A path much abused?

Although most of the drug companies publicly advocate self regulation to avoid unethical marketing practices, the situation on the ground is much different, across the world. 

The following are just a few examples of serious business consequences faced by some of the well-known global pharma and biotech majors, besides many others, from the United States Department of Justice, for alleged off-label promotion of drugs: 

  • On November 4, 2013, Johnson & Johnson (J&J) was asked to pay more than US$ 2.2 billion to resolve criminal and civil liability arising from allegations relating to the prescription drugs Risperdal, Invega and Natrecor, including promoting for uses not approved as safe and effective by the USFDA and payment of kickbacks to physicians and to the nation’s largest long-term care pharmacy provider.  
  • On July 30, 2013, Wyeth Pharmaceuticals Inc., a pharmaceutical company acquired by Pfizer, Inc. in 2009, agreed to pay US$490.9 million to resolve its criminal and civil liability arising from the unlawful marketing of the prescription drug Rapamune for uses not approved as safe and effective by the USFDA. 
  • On December 19, 2012, Amgen Inc. pleaded guilty and paid US$762 million to resolve criminal liability and false claims allegations.
  • On July 2, 2012 GlaxoSmithKline LLC (GSK) pleaded guilty and paid US$3 billion to resolve its criminal and civil liability arising from the company’s unlawful promotion of certain prescription drugs, its failure to report certain safety data, and its civil liability for alleged false price reporting practices. This resolution is the largest health care fraud settlement in the US history and the largest payment ever by a drug company, so far. 
  • On May 7, 2012, Abbott Laboratories Inc. pleaded guilty and agreed to pay US$1.5 billion to resolve its criminal and civil liability arising from the company’s unlawful promotion of the prescription drug Depakote for uses not approved as safe and effective by the USFDA.  This resolution is the second largest payment by a drug company and includes a criminal fine and forfeiture totaling US$700 million and civil settlements with the federal government and the states totaling US$800 million.  Abbott also was reportedly subjected to court-supervised probation and reporting obligations for Abbott’s CEO and Board of Directors.
  • On October 21, 2011, Pfizer Inc. agreed to pay US$14.5 million to resolve false claims allegations related to its marketing of the drug Detrol. 
  • On June 10, 2011, Novo Nordisk was asked to pay US$25 million to resolve allegations of off-label promotion of Novoseven.
  • On September 30, 2010, Novartis agreed to pay US$422.5 million to settle criminal and civil investigations into the marketing of the anti-seizure medicine Trileptal and five other drugs. The government accused Novartis of mislabeling, paying illegal kickbacks to health care professionals through speaker programs, advisory boards, entertainment, travel and meals. 

Hence, it appears that the path followed by many pharma players to inform the doctors about the judicious off-label use of drugs only in circumstances where approved treatments have failed, is being much abused. 

A conflict of interest? 

Many doctors believe that there is also a distinct upside for off-label use of drugs, as flexibility of a physician to prescribe drugs off-label offers important advantages too, especially in circumstances where approved treatments have failed. This is indeed true and indisputable.

However, the reality is, many pharma industry, in general, actively encourage off-label use of drugs for commercial benefits through expanded use of their respective brands.

Aggressive drug promotion for various off-label uses, reportedly being so widespread and indiscriminate, many physicians can’t even remember the approved indications of drugs. Hence, they do not necessarily go for off-label use only when approved treatments have failed.  In this context, on November 23, 2015, ‘The Wall Street Journal (WSJ)’ in an article titled, “Risk of Off-Label Uses for Prescription Drugs” reported as follows:

“A 2009 study published in the journal Pharmacoepidemiology and Drug Safety found that 1,199 physicians in a national survey were able to identify the FDA-approved indication of 22 drugs only about 55% of the time. The physicians surveyed included primary-care doctors and psychiatrists.” 

On the other hand, the patients generally expect that the prescribed drugs will be safe. They want to administer evidence based approved medicines. Some of them have even started expressing that these evidences must also be disclosed to them.

Hence, there seems to exist a clear conflict of interest in this matter between the patients, drug manufacturers and perhaps the doctors, as well.

Conclusion:

The magnitude of general off-label use of drugs is reportedly increasing and is likely to increase further, exposing patients to increased risks of ADEs.  Although the business consequences of getting engaged in this unwanted process indiscriminately could at times be quite adverse, in the balance of probability between slim chances of getting caught, and expected creamy return, many pharma players continue to feel that this risk is worth taking.

Therefore, the moot question that needs a pragmatic answer is, for patients’ safety, when the global and local pharma majors talk about prescriptions of only impeccable evidence based medicine, do they walk the talk?

‘Repurposing’ Older Drugs: Has The Process Started Rolling?

Posted on by

On October 22, 2015, BBC News reported, “The world’s largest clinical trial to examine whether aspirin can prevent cancers returning has begun in the United Kingdom (UK).”

About 11,000 people, who have had early bowel, breast, prostate, stomach and esophageal cancer will be involved in this study with one tablet a day dosage for five years. This trial is being funded by ‘The Charity Cancer Research, UK’ and ‘The National Institute for Health Research (NIHR).’

The scientists feel, if it works, this ‘repurposing’ of an older and much-known drug would be a “game-changing” one. It would then be able to provide a cheap and effective alternative to prevent recurrence of cancer to a large number of cancer survivals. Interestingly, no global pharma players are involved in this cancer prevention research, as yet. 

Aspirin was developed by Bayer way back in 1897 for pain and inflammation. Thereafter, the scientists found a ‘repurpose’ in its use as an anti-platelet drug for treating and preventing heart attacks and strokes.

Similarly, the anti-inflammatory drug Ibuprofen, which was developed by Boots in the 1960s for the treatment of rheumatoid arthritis, is now showing promises that it can help protect against Parkinson’s disease.

Again, a number of studies claim that statins, a cholesterol-reducing drug, can help prevent Alzheimer’s Disease, resulting in low levels of beta-amyloid. Further research needs to be done in this area, as this finding has not been universally accepted, just yet.

All such commendable initiatives, throw open a relevant question for debate: ‘Can the existing drugs be re-examined in a systematic manner to discover their other possible radically new usages at a much lesser treatment costs to patients?’

In my view, available data emphatically prompts the answer ‘Yes’ and I shall deliberate on on that in this article.

‘Repurposing’ older drugs:

The Oxford Dictionary meaning of ‘repurpose’ is: ‘Adapt for use in a different purpose.’

Accordingly, the process of discovering new usages of older drugs is often called by many scientists as ‘repurposing’.   

Currently, we come across various articles reporting a number of such new initiatives. This process is safer, much less expensive and takes much lesser time.

These laudable R&D initiatives needs encouragement from all stakeholders, especially from the Government. Given proper focus and attractive financial and other incentives, more and more players are expected to get attracted to a different genre of innovation. It is a whole new ball game of discovering new purposes of old and cheaper drugs with known and well-documented long term safety profile.

Some old drugs with ‘new purpose’: 

The following table gives an example of some well known older drugs, for which fresh R&D initiatives discovered their new purpose of treatment, at a much cheaper cost: 

Drug Old Indication New purpose
Amantadine Influenza Parkinson’s Disease
Amphotericin Antifungal Leishmaniasis
Aspirin Inflammation, pain Antiplatelet
Bromocriptine Parkinson’s disease Diabetes mellitus
Bupropion Depression Smoking cessation
Colchicine Gout Recurrent pericarditis
Methotrexate Cancer Psoriasis, rheumatoid arthritis

(Source: Indian Journal of Applied Research, Volume: 4, Issue: 8, August 2014)  

A clarion call to join this movement:

The well-known researcher, Dr. Francis S. Collins, the Director of the National Institutes of Health (NIH) in a TED talk (video) strongly argued in favor of ‘translational research’ to produce better drugs, faster. To make this process to work successfully Francis Collins hopes to encourage global pharmaceutical companies to open up their stashes of drugs that have already passed safety tests, but that failed to successfully treat their targeted disease. 

He wants to study, how drugs approved for one disease could successfully treat another or more ailments and also gave examples of the following drugs, which I am quoting below, as such:

  • Raloxifene: The FDA approved Raloxifene to reduce the risk of invasive breast cancer in postmenopausal women in 2007. It was initially developed to treat osteoporosis.
    .
  • Thalidomide: This drug started out as a sedative in the late fifties, and soon doctors were infamously prescribing it to prevent nausea in pregnant women. It later caused thousands of severe birth defects, most notably phocomelia, which results in malformed arms and legs. In 1998, thalidomide found a new use as a treatment for leprosy and in 2006 it was approved for multiple myeloma, a bone marrow cancer.
    .
  • Tamoxifen: This hormone therapy treats metastatic breast cancers, or those that have spread to other parts of the body, in both women and men, and it was originally approved in 1977. Thirty years later, researchers discovered that it also helps people with bipolar disorder by blocking the enzyme PKC, which goes into overdrive during the manic phase of the disorder.
    .
  • Rapamycin: This antibiotic, also called sirolimus, was first discovered in bacteria-laced soil from Easter Island in the seventies, and the FDA approved it in 1999 to prevent organ transplant rejection. Since then, researchers have found it effective in treating not one but two diseases: Autoimmune Lymphoproliferative Syndrome (ALPS), in which the body produces too many immune cells called lymphocytes, and lymphangioleiomyomatosis, a rare lung disease.
    .
  • Lomitapide: Intended to lower cholesterol and triglycerides, the FDA approved this drug to treat a rare genetic disorder that causes severe cholesterol problems called homozygous familial hypercholesterolemia last December.
    .
  • Pentostatin: This drug was created as a chemotherapy for specific types of leukemia. It was tested first in T-cell-related leukemias, which didn’t respond to the drug. But later NIH’s National Cancer Institute discovered that the drug was successful in treating a rare leukemia that is B-cell related, called Hairy Cell Leukemia.
    .
  • Sodium nitrite: This salt was first developed as an antidote to cyanide poisoning and, unrelated to medicine, it’s also used to cure meat. The National Heart, Lung, and Blood Institute is currently recruiting participants for a sodium nitrite clinical trial, in which the drug will be tested as a treatment for the chronic leg ulcers associated with sickle cell and other blood disorders.
  • Zidovudine (AZT): The first antiviral approved for HIV/AIDS in 1987.
  • Farnesyltransferase inhibitor (FTI): This was used to successfully treat children with the rapid-aging disease Progeria in a 2012 clinical trial.

“None of these drugs could have been developed without collaborations between drug developers and researchers with new ideas about applications, based on molecular insights about disease,” Dr. Collins said.

The examples that I have given, so far, on ‘repurposing’ older drugs are not exhaustive, in any way, there are more such examples coming up almost regularly.

The key benefits: 

The key benefits of ‘repurposing’ older drugs may be summarized as follows:

  • Ready availability of the starting compound
  • Previously generated relevant R&D data may be used for submission to drug regulators
  • Makes clinical research more time-efficient and cost-effective
  • Possibility of much quicker market launch

Slowly gaining steam: 

On November 27, 2012, ‘The Guardian’ reported that a number of university-based spin-outs and small biotech companies are being set up in the United States to find new purpose for old drugs. They express interest especially, on those drugs, which were shelved as they did not match the desired efficacy requirements, though showed a good overall safety profile.

Such organizations, take advantage of the declining cost of screening, with some compound libraries, such as, the Johns Hopkins library, which includes 3,500 drugs, available for screening at a small charge, the report highlighted.

Quoting a specialist, the report stated, “Existing drugs have been shown to be safe in patients, so if these drugs could be found to work for other diseases, then this would drastically reduce drug development costs and risks. Of 30,000 drugs in the world, 25,000 are ex-patent – it’s a free-for-all.”

‘Repurposing’ may not attract many pharma players, Government should step in:

Notwithstanding the clarion call of Dr. Francis Collins to global pharma players for their active participation in such projects, I reckon, the positive response may not be too many, because of various reasons.

Although, ‘repurposed’ drugs offer similar or even greater value to patients than any comparable ‘me-too’ New Chemical/Molecular Entity (NCE/NME), there may not possibly be any scope here for ‘Obscene Pricing’, such as ‘Sovaldi’ and many others, as some experts feel. And that’s the reality.

Moreover, new usages of the same old molecule, in all probability, may not get any fresh Intellectual Property (IP) protection in India, either.

Hence, considering the health interest of patients, in general, the Government should assume the role of ‘prime mover’, primarily to set the ball of ‘repurposing of older drugs’ rolling in India. This has already started happening in some of the developed countries of the world, which I shall dwell upon here.

Funding clinical development for ‘repurposing’:

Let me give a couple of examples of funding such admirable initiatives in two different countries.

I have already mentioned above that the clinical development for ‘repurposing’ Aspirin in the prevention of cancer, is being funded by the charity Cancer Research UK and the National Institute for Health Research (NIHR).

In a similar initiative, National Institutes for Health (NIH) of the United States, launched the ‘National Center for Advancing Transnational Sciences (NCATS), in May 2012.

New Therapeutic Uses program of NCATS helps to identify new uses for drugs that have undergone significant research and development by the pharma industry, including safety testing in humans. NIH claims that ‘using drugs that already have cleared several key steps in the development process gives scientists nationwide a strong starting point to contribute their unique expertise and accelerate the pace of therapeutics development.’

By pairing researchers with a selection of specific drugs, NCATS program tests ideas for new therapeutic uses, ultimately identifying promising new treatments for patients. Funding for this purpose is done by NCATS through NIH. For example, In July 2015, NCATS planned a funding of around US$3 million to support four academic research groups to test a selection of drugs for new therapeutic uses, as follows:

  • Type 2 diabetes
  • Glioblastoma (one of the most aggressive brain tumors in adults)
  • Acute myeloid leukemia (an aggressive blood cancer)
  • Chagas disease (a neglected tropical disease that causes heart, digestive and neurological problems)

According to NIH, each award recipient will test a selected drug for its effectiveness against a previously unexplored disease or condition. The industry partners for these projects are AstraZeneca and Sanofi.

Can it be done in India?

Of course yes, provided the Government considers health care as one its priority focus areas with commensurate resource deployment of all kinds for the same.

As things stand today, India still remains beyond any visibility to give a tangible shape to this specific concept of ‘repurposing’ of older drugs. There does not seem to be any other valid reason why similar model of funding can’t be followed locally too, for this purpose.

The nodal agency to spearhead such initiatives, and to create appropriate groundswell to help gain a critical mass, may well be the ‘Council of Scientific & Industrial Research (CSIR)’ or any other body that the Government decides in consultation with domain experts, together with reasonable financial incentives for commercialization of new usages at an affordable cost.

Conclusion:

As we all know, many people, across the world, are currently going through the pain of seeing their loved ones suffer, and even die, from serious ailments, the treatments of which either do not exist or when exist, the therapy costs may be out of reach of a vast majority of patients. In tandem, the R&D pipeline of the global pharma industry is gradually drying up.

In a situation like this, drug ‘repurposing’ that is directed towards meeting unmet medical needs of patients of all types irrespective of financial status, needs to be increasingly encouraged and pursued as a critical solution to this growing problem.

The good news is that some global pharma majors, though very few in number, have now expressed their intention to salvage their failed molecules and are open to help explore whether such drugs may work in other disease conditions.

India seems to be still miles away from this space, and a bit directionless too. That said, the country is scientifically quite capable of making up the lost ground in this area, provided the Government decides so, garnering requisite wherewithal.

Thus, in my view, the process of ‘repurposing’ older drugs has already started rolling in some major countries of the world, in a well structured manner with requisite funding in place. Tangible outcomes are already noticeable today, with some examples quoted in this article.

As Dr. Francis Collins said, collaborations between drug developers and researchers with new ideas about applications, based on molecular insights about disease are critical in the way forward to achieve this cherished goal in a sustainable manner.

Does India Produce ‘World Class’ Medicines, For All?

Posted on by
Reply

India has already achieved a staggering number In terms of quantity or volume of generic medicines that it produces not just for India, but for many developed, developing and poorer countries, across the world. For this reason, India is popularly known as ‘The Pharmacy of The World’. No one questions this number at all, rather looks at India with a sense of admiration in this regard.

Nevertheless, for driving this volume growth trend further north, in a consistent and sustainable way, Indian pharma sector must ensure that its huge volume growth engine remains firmly placed on a solid bedrock of ‘world class’ drug quality, always. Any compromise in this crucial area, could strike a critical blow to this ‘tower of national pride’.

Ongoing several embarrassing incidents related to the drug manufacturing quality standards in India, are increasingly fueling the apprehension, whether or not India produces ‘World Class’ medicines for all patients across the world, independent of any other criteria, financial or otherwise. The debate has now taken an interesting turn, especially after near confirmation of this apprehension by the top drug regulator of India.

In this article, I shall discuss this important issue that hugely impacts all of us, giving my own perspective to it. Let me begin with one of the most recent incidents on the subject, involving the numero-uno of Indian pharmaceutical industry.

An overseas new product launch got prematurely aborted?

On September 25, 2015, by a Press Release, Sun Pharma Advanced Research Company Ltd. (SPARC) announced a major set back for the company. The set back may not be so much in terms of the company’s estimated revenue loss, but more on public perception across the world, about the manufacturing quality standards followed even by the top most pharma company of India.

SPARC made a public announcement through media that on March 2015 it had received a final approval from the Food and Drug Administration of the United States (USFDA) for the anti-epileptic drug – Elepsia XR (Levetiracetam extended-release tablets 1000 mg and 1500 mg). However, in the Complete Response letter (CRL) to the company’s New Drug Application (NDA) for the product, the USFDA has revoked its earlier approval, citing that the compliance status of the manufacturing facility was not acceptable on the date of approval. Elepsia XR is to be manufactured at Sun Pharmaceutical Industries Ltd (SPIL)’s Halol facility in Gujarat, the announcement said.

Sun Pharma had reportedly indicated in June 2015 that the Company had been working “very aggressively” to find partners for the product. It had “some advanced discussions” and aimed to launch the drug by the second half of fiscal 2016.

The international media lapped it up and reported this development with eye-catching headlines, one such was:

“India’s Sun Pharma research arm sees FDA nod for Elepsia XR yanked by FDA on manufacturing.”

Not a one-off isolated incident:

This matter can no way be treated as a one-off and an isolated incident, as it fits in well with a series of similar events, spanning over the last few years.

Looking at these disturbing adverse reports from the foreign drug regulators on the drug manufacturing quality standards in India, together with recent comments of the Indian drug regulator on the subject, serious health safety concerns on overall drug quality in the country, are being expressed now. The concern includes the local patients in India, as well.

Can the core issue be wished away?

Up until today, USFDA has altogether warned 39 manufacturing sites of 27 Indian pharma companies for breach of data integrity and not following specified manufacturing quality standards. The agency has also expressed that it treats these as potentially dangerous medicines for the consumption of patients in the US.

In 2015 alone, USFDA has reportedly detected such serious ‘short comings’ with 6 Indian drug makers, till September. A report from Financial Times (FT) states that the above numbers do not include the testing facilities facing sanctions from the European Medicines Agency (EMA) in the GVK Biosciences related cases or from the World Health Organizations (WHO).

What is most worrying, none can possibly still fathom, if these alleged ‘reprehensible’ manufacturing practices are restricted to just a few players or are all pervasive across the Indian drug industry.

When the foreign regulators, such as USFDA and Medicines and Healthcare Products Regulatory Agency (MHRA) of the United Kingdom (UK) continue raising the red flags on the manufacturing standards of the top pharma players of India, including the numero uno, a chilling sensation flows through the spine, as it were. The moot question that comes up: Are all the drugs manufactured in India safe for the local patients, offering desirable efficacy?

Keeping these in perspective, would it be prudent to wish away the drug quality related critical issues, raising a conspiracy theory against the US or EU or suspend discussions on any Foreign Trade Agreement (FTA)? I don’t reckon so, and would touch upon this point in course of my discussion below.

The murmur among the US doctors:

According to an article from Reuters of March 18, 2014, titled “Unease grows among US doctors over Indian drug quality”, some US doctors are also expressing concerns about the quality of generic drugs supplied by Indian manufacturers, following a flurry of recalls and ‘import bans’ by the USFDA.

This concern has been prompted by the fact that India supplies about 40 percent of generic and over-the-counter drugs used in the United States, making it the second-biggest supplier after Canada.

Not much complaint from the Indian doctors:

This is intriguing. Despite so much of furore of the regulatory agencies in the US and EU on the Indian drug quality standards, not much concern on the same has been expressed by the medical practitioners in India, just yet.

It appears, by and large, Indian doctors believe that branded generics are generally of good quality, and the quality of generics without a brand name is not as reliable, always.

This logic is beyond my comprehension. How come just fixing a brand name on a generic formulation makes it more acceptable in terms of quality, when both branded generics and generics without a brand name, have obtained the same regulatory approval from the same drug regulators in India and following the same regulatory process?

As you will see below, the situation has changed further now, especially after the admission of the DCGI about non-compliance of global manufacturing quality standards by majority of the formulation manufacturers in India, as reported by the media. The only silver lining to it is that whatever is being currently manufactured in India, presumably meets the regulators approval in conformance to the Drugs and Cosmetics Act of the country, without any credible data to the contrary.

Does India produce drugs of ‘World Class’ quality for all?

The key question that is being raised today: Does India produce ‘world class’ drugs and for all? This is mainly because, manufacturers of ‘world class’ drug quality always aim at competing for quality on the best global standards to remain competitive in the international markets, in all parameters. This should hold good even for the domestic Indian market, for all drugs, consumed by all the local patients, irrespective of their financial status.

A lurking fear keeps lingering, primarily apprehending that Indian drug manufacturing quality related issues are not confined only to the importers in the developed world, such as, the United States, European Union or Canada. There is no reason to vouch for either, that such gross violations are not taking place with the medicines consumed by the patients in India or in the poorer nations of Africa and other similar markets.

A recent international study on Indian drug quality:

The following study further aggravates the angst.

The September 2014 ‘Working Paper 20469’ of ‘The National Bureau of Economic Research (NBER)’ Cambridge, USA, titled “Poor Quality Drugs and Global Trade: A Pilot Study’, epitomizes the following:

  • Experts claim that some Indian drug manufacturers cut corners and make substandard drugs for markets with non-existent, under-developed or emerging regulatory oversight, notably Africa.

The study assessed the quality of 1470 antibiotic and tuberculosis drug samples that claim to be made in India and were sold in Africa, India, and five mid-income non-African countries and found:

      – 10.9 percent of these products fail a basic assessment of active pharmaceutical                  ingredients (API) 

       - The majority of the failures are substandard (7 percent) as they contain some correct          API but the amount of API is under-dosed.

        – The distribution of these substandard products is not random, they are more likely             to be found as unregistered products in Africa than in India or non-African                           countries.

Claiming that the findings are robust, the NBER study points towards one likely explanation that Indian pharmaceutical firms and/or their export intermediaries do indeed differentiate drug quality according to the destination of consumption.

Incomprehensible?

The above facts are alarming, especially when these flow from a survey report of a credible international institution. This is incomprehensible too, as all these are medicines, and are meant to be for relief or cure of ailments that the patients are suffering from, irrespective of whether they are from the developed, developing or poorer countries.

If it is still happening today, why are those manufacturers allowed by the Indian drug regulators to discriminate between the patients of the developed countries and the developing world, including India, to meet the same health care needs? This is absolutely cruel by any standard, undoubtedly.

‘As you sow, so shall you reap’:

Just as the above well-known proverb says that the actions or deeds repay in kind, reasonably frequent ‘import bans’ by the foreign drug regulators on drug quality norms, has probably prompted booming generic drug exports of Indian pharma now slowing down to US$15.3 billion in 2014-15, from US $14.84 billion in 2013-14.

Along side, these avoidable incidents have significantly dented India’s image as the ‘pharmacy of the world’, manufacturing affordable and high quality generic formulations for the patients across the world.

Indian drug regulator too now thinking afresh? 

Yet another relevant question comes up. What happens, if during treatment of serious ailments such drugs fail to act for inferior quality? How would one possibly know in India, whether a death has occurred due to unresponsive poor quality of drugs or on account of severity of the ailments? How helpless are the patients in such a situation?

This sad feeling gets even stronger, when well after a prolonged defense of the high quality of drugs manufactured in India, no less than the Drug Controller General of India (DCGI), airs his second thought on the same issue. This is vindicated by recent media reports on this subject.

On September 30, 2015, a media report stated that being virtually flustered by the USFDA and the drug regulators in the European Union, the Drug Controller General of India (DCGI) would place a proposal before the Ministry of Health, within the next six months, for an amendment to the existing pharmaceutical manufacturing laws under Drugs and Cosmetics Act, 1940, and Drugs and Cosmetics Rules, 1945, in order to ‘bring them on par with international standards’.

The DCGI now believes that this remedial measure would raise drug manufacturing standards in India in line with the global cGMP standards, recommended by the World Health Organization (WHO).

Currently, out of around 8,000 drug manufacturers in India, only 10 to15 percent are following the WHO guidelines, the report stated quoting the DCGI.

The new revelation further strengthens the apprehension about quality of drugs that Indian patients are consuming in the country with a strong hope for relief from the diseases that they suffer from.

The DCGI apparently admitted it, when he was quoted saying in the above report, “India has become a pharmacy of the world. So, we cannot live in isolation and will have to meet their expectations. Our system is in the process of improving.”

DCGI statement follows an important Government decision:

It is worth noting that the above comment of the DCGI comes close on the heels of an important Government decision in this regard.

On August 12, 2015, The Press Trust of India (PTI) reported that to facilitate domestic manufacture of quality medical products, the Cabinet Committee on Economic Affairs (CCEA) on that day approved a proposal of strengthening and upgrading the drug regulatory system both at the Central and state level. The committee approved a budget of of INR17.5 billion (US$270 million) on this account.

The up gradation and strengthening of the system will also include setting up of new laboratories and training academy for regulatory and drug testing officials, the report added.

Yet Another significant development:

On October 5, 2015, in yet another significant development in this direction, the Medicines and Healthcare products Regulatory Agency (MHRA) of the United Kingdom (UK), by a ‘Press Release’, announced signing of a Memorandum of Understanding (MOU) with the Central Drugs Standard Control Organization (CDSCO) of India.

This agreement will increase collaboration between India and UK in the area of medicines and medical devices with the aim of further improving public safety in both the countries. It is worth noting, around 25 percent of generic drugs consumed in the UK are made in India. Hence, the concern of MHRA over the safety of those medicines is understandable.

I wrote in this Blog on USFDA ‘Import Bans’ in my article of November 11, 2013, titled ‘USFDA ‘Import Bans’: The Malady Calls For Strong Bitter Pills.’

Conclusion:

A valid question that is being asked by many in India today, why the issues like, alleged cGMP non-compliance, data fudging and falsification of other documents, especially with USFDA, have multiplied suddenly over the last few years. Why not as many of such issues were raised by the USFDA before around 3 to 4 years?

This is primarily because, of late the inspectors from the USFDA have significantly increased their efforts to ensure the drug manufacturing facilities from where both generic Active Pharmaceutical Ingredients (API) and formulations are exported to the US, strictly follow the drug manufacturing standards, as stipulated by the USFDA. The fact that India supplies about 40 percent of generic and over-the-counter drugs currently used in the United States, has prompted this requirement to safeguard health safety of the American patients.

Such stringent USFDA audits commenced in 2012, when US Congress passed the FDA Safety and Innovation Act. This legislation, among others, requires the USFDA auditing all foreign facilities that make drugs for export to the US, as frequently as it does for the domestic drug manufacturing plants. Thereafter, we have seen a spurt in the USFDA inspections of the pharma manufacturing facilities in India, where from drugs are exported to the US. Hence, there does not seem to be any other credible ‘conspiracy theory’ on this issue.

As reported in ‘The New York Times’ of February 14, 2014, the same DCGI almost brushing aside the gravity of the situation arising out of repeated ‘import bans’, commented at that time, “If I have to follow US standards in inspecting facilities supplying to the Indian market, we will have to shut almost all of those.”

The top drug regulator seems to have changed his mind since then, and presumably is thinking differently now, as the Indian media very recently quoted the DCGI saying “India has become a pharmacy of the world. So, we cannot live in isolation and will have to meet their expectations. Our system is in the process of improving.”

This is a good omen, especially for the patients in India. If and when it gets translated into reality, with Kudos to the DCGI, we all would feel very proud saying, “The Pharmacy of the World now produces the World-Class drugs, for all” …God willing!
