Drugs From The Same Indian Plant: Safe For Europe, Unsafe For America, Why?

Posted on by

Good number of stories on US-FDA banning several drug manufacturing facilities of major domestic players of India over serious quality related issues, have been doing the rounds since about a year and almost at a regular interval.

The quagmire has snowballed into serious apprehensions on the quality of Indian generic drugs, across the globe. Various statements of US-FDA Commissioner Margaret Hamburg, during her much talked about maiden visit to India, in February 2014, added further credence to the issue.

“If you want our market, meet our standards”:

During Hamburg’s India visit, her reported candid warning to the Indian drug exporters to America added further fuel to the above concern in India. She clearly underscored:

“If you want our market, meet our standards.”

Even in the face of this stern warning, when major drug manufacturers of India, such as, Ranbaxy, Wockhardt, Sun Pharma and some others continued to fail in meeting US-FDA drug quality standards in their respective plants, I wrote the following in one of my earlier blog posts titled, “Does India Believe in Two Different Drug Quality Standards?”:

“In a situation like this, especially when many Indian manufacturers are repeatedly failing to meet the American quality standards, the following questions come up:

  • Is the US-FDA manufacturing requirement too troublesome, if not oppressive?
  • If not, do the Indian and other patients too deserve to have drugs conforming to the same quality standards?

Answers to these questions are absolutely vital to convince ourselves, why should Indian patients have access to drugs of lower quality standards than Americans, with consequential increase in their health risks?”

The first question on ‘troublesomeness’ now partly answered?

This is because another recent media report brought to the fore that, having completed their assessment of drug manufacturing violations at Ranbaxy’s facility in Toansa, European regulators have said although deficiencies were found, they pose no risk to public health. The regulators said they were satisfied by corrective measures put in place by the company after U.S. regulators found deviations in January.

The report also highlights that this assessment of the European regulators stands in stark contrast to the response of US regulators to the deficiencies found at the same plant.

It is worth noting that US-FDA continues to restrict Ranbaxy from making and selling pharmaceutical ingredients from the Toansa facility “to prevent substandard quality products from reaching US consumers.”

The same plant meets drug safety standards of Europe, but ‘unsafe’ for America!

Quite contrary to the above stern statement of US-FDA, according to the above report from Reuters, European drug regulators commented as follows:

“The inspection team concluded that there was no evidence that any medicines on the EU market that have an active pharmaceutical ingredient manufactured in Toansa were of unacceptable quality or presented a risk to the health of patients taking them.” 

The further added, “This conclusion was supported by tests of samples of these medicines, all of which met the correct quality specifications.”

Regulatory audit standards were the same for both EU and US regulators:

It is also interesting to note from the report that according to a statement from the US-FDA:

“EMA and FDA inspected the Toansa facility using similar quality standards and underlying principles of current good manufacturing practices.”

Was the decision of US-FDA ‘import ban’ subjective?

This critical question arises because of another US-FDA statement that states as follows:

“While inspections were similar, the two regulatory authorities applied their own, differing, regulatory and legal standards to address the violations.”

Subjectivity in decision-making could encourage “Conspiracy Theory”:

Generic drugs currently contribute over 80 percent of prescriptions written in the US. Around 40 percent of prescriptions and Over The Counter (OTC) drugs that are now sold in the United States come from India. Almost all of these are cheaper generic versions of patent expired drugs. Total annual drug export of India, currently at around US$ 15 billion, is more than the domestic turnover of the pharma industry. Hence, India’s commercial stake in this area is indeed mind-boggling.

In a situation like this, the apprehension of subjectivity in the decision making process of US-FDA related to ‘import bans’, if linked with, say for example, even the missed opportunities for ‘first to launch’ generic versions of several patent-expired blockbuster drugs in the United States by Ranbaxy, could lead to much undesirable ‘Conspiracy Theory’, further souring the relationship between India and America.

As I mentioned in one of my earlier blog posts titled “Loss of Ranbaxy Gain of Big Pharma…And Intriguing Coincidences”, when the emerging dots associated with the missed opportunities for ‘first to launch’ generic versions of drugs like, Lipitor (Pfizer), Diovan (Novartis) and Nexium (AstraZeneca) are connected, an uncomfortable pattern could emerge favoring Big Pharma and obviously adversely affecting Indian companies like Ranbaxy.

The First Dot: Uncertainty over Lipitor generic launch:

Like many other large Indian players, ‘first to launch’ strategy with the new generic drugs has been the key focus of Ranbaxy since long, much before its serious trouble with the US-FDA begun in 2008. ‘Import Bans’ on two of its manufacturing facilities by the US regulator in that year created huge uncertainty in its launch of a generic version of Pfizer’s anti-lipid blockbuster drug Lipitor in 2011. On time launch of a generic version of Lipitor was estimated to have generated a turnover of around US$ 600 million for Ranbaxy in the first six months and commensurate loss to Pfizer for the generic entry.

Despite its neck deep trouble with the US-FDA at that time, Ranbaxy ultimately did somehow manage to launch generic Lipitor, after partnering with Teva Pharmaceutical of Israel.

The Second Dot: Indefinite delay in Diovan generic launch:

Lipitor story was just the beginning of Ranbaxy’s trouble of not being able to translate its ‘first to launch’ advantage of patent-expired blockbuster drugs into commercial success, thus allowing the Big Pharma constituents to enjoy market monopoly with their respective blockbuster drugs even after patent expiry.

Despite Ranbaxy holding the exclusive rights to market the first generic valsartan (Diovan of Novartis and Actos of Takeda) for 180 days, much to its dismay, even after valsartan patent expiry in September 2012, a generic version of the blockbuster antihypertensive is yet to see the light of the day. However, Mylan Inc. has, now launched a generic combination formulation of valsartan with hydrochlorothiazide.

US-FDA drug ‘Import Ban’ from the concerned manufacturing facility of Ranbaxy gave rise to this hurdle favoring the Big Pharma, as discussed above.

As a result, Novartis in July 2013 reportedly raised its guidance announcing that the company now expects full-year sales to grow at a low single-digit rate, where it had earlier predicted net sales to turn up flat. It also guided for core earnings to decline in the low single digits, revising guidance for a mid-single-digit drop.

The Third Dot: Delay in Nexium generic launch:

Ranbaxy had earlier created for itself yet another opportunity to become the first to launch a generic version of the blockbuster anti-peptic ulcerant drug of AstraZeneca – Nexium in the United States, as the drug went off patent on May 27, 2014. However, due to recent US-FDA import ban from its Toansa plant, this opportunity too seems to be fading away for Ranbaxy.

Delay in the launch of generic Nexium, which incidentally is the second-biggest seller of AstraZeneca, would make a big impact on the predator-chased company’s profit.

With the global sales of Nexium at US$ 3.87 billion and US sales at US$ 2.12 billion in 2013, retaining its monopoly status in the all-important US market beyond the end of May would not only limit a forecast decline in AstraZeneca’s 2014 earnings, but would also protect bonuses for top management of the British pharma giant, as the above report says.

Conclusion:

Let me hasten to add yet again, while highlighting the stark differences of interpretations on drug quality standards of the same plant between the European and American regulators and connecting the dots of significant missed opportunities of the Indian drug manufacturers, I do not intend to postulate any ‘Machiavellian Hypothesis’.

I just wanted to establish that both alleged ‘subjective’ decision making process of the US-FDA and coincidences of a series of missed opportunities encountered by the Indian drug manufacturers related to first to launch generics in America are now realities, which if remain unaddressed could germinate into a ‘Conspiracy Theory’, at least in some corners. This could further sour existing Indo-US relationship.

While, I am confident that the new government of India with its, so far, well demonstrated ‘Can Do’ spirit would take these critical issues up in the ensuing bilateral ministerial level meetings, an immediate and in-depth study should also be initiated with valuable inputs from the independent experts to ferret out the real reasons behind these facts, including:

  • Why are the cGMP related issues in India repeatedly arising mainly with the US-FDA?
  • Are  the requirements of the US-FDA though too onerous for the Indian drug manufacturers, yet reasonable as per global norms?
  • If so, how come the drugs manufactured in the same Indian plant though declared unsafe by the US-FDA, considered safe by the European regulators?

Transparency in Drug Trial Data: Thwarted by Lobbyists or Embroiled in Controversy?

Posted on by
Reply

Based on a leaked letter from overseas pharma industry bodies, a leading international daily in late July 2013 reported:

“Big pharma mobilizing patients in battle over drugs trials data.”

Some experts consider it as a poignant, if not a bizarre moment in the history of drugs development, keeping patients’ interest in mind. However, the concerned trade bodies could well term it as a business savvy strategy to maintain sanctity of ‘Data Exclusivity’ in real sense.

That said, it is important for the stakeholders to figure out where exactly does this strategy stand between the larger issue of patients’ drug safety and efficacy concerns and the commercial interest of the innovator companies to grow  their business.

Lack of transparency in drug trials data and consequences:

Outside pharmaceutical marketing, some of the biggest scandals in the drug industry have been alleged hiding of data related to negative findings in drug Clinical Trials (CTs) by the innovator companies.

Many stakeholders have already expressed their uneasiness on this wide spread allegation that research based pharmaceutical companies publish just a fraction of their CT data and keep much of the drug safety related information to themselves. Not too distant withdrawals of blockbuster drugs like Vioxx (Merck) and Avandia (GSK) will vindicate this point.

Examples of global withdrawals of drugs, including blockbuster ones, available from various publications, are as follows.

Questionable efficacy for the treatment of sepsis

A recent example:

A recent report indicates that Japan (Tokyo) based Jikei University School of Medicine plans to withdraw a paper on the hypertension drug Diovan of Novartis from the prestigious British Medical Journal (BMJ) due to “data manipulation,” suggesting the drug could help treating other ailments.

The report also indicates that an investigative panel formed by the university to look into the allegations of ‘rigged data’ for Diovan concluded that the results were cooked.

The decision of the Japanese University to withdraw this paper is expected to hurt the reputation of Novartis Pharma AG and at the same time raise ethical concerns about the company’s behavior concerning its best-selling hypertension drug, the report says.

Drug regulators contemplating remedial measures:

Now being cognizant about this practice, some drug regulators in the developed world have exhibited their keenness to disband such practices. These ‘gatekeepers’ of drug efficacy and safety are now contemplating to get the entire published CT data reanalyzed by the independent experts to have a tight leash on selective claims by the concerned pharma companies.

A review reportedly estimates that only half of all CTs were published in full and that positive results are twice as likely to be published than negative ones.

Recently the European Medicines Agency (EMA) has published a draft report for public consideration on greater openness of CT data. As stated above, this proposal allows independent experts to conduct a detail analysis on the safety and effectiveness of new drugs.

Mobilizing patients to thwart transparency?

Interestingly, as stated in the beginning, it has recently been reported that to thwart the above move of the drug regulator in favor of patients’ interest:

“The pharmaceutical industry has mobilized an army of patient groups to lobby against plans to force companies to publish secret documents on drugs trials.”

The same report highlights that two large overseas trade associations had worked out a grand strategy, which is initially targeted at Europe. This is for the obvious reason that the EMA wants to publish all of the clinical study reports that drug companies have filed, and where negotiations around the CT directive could force drug companies to publish all CT results in a public database.

Embroiled in controversy:

It has also been reported simultaneously, “Some who oppose full disclosure of data fear that publishing the information could reveal trade secrets, put patient privacy at risk, and be distorted by scientists’ own conflicts of interest.”

Pharmaceutical trade associations in the west strongly argue in favor of the need of innovator companies to keep most of CT data proprietary for competitive reasons. They reiterate that companies would never invest so much of time and money for new drug development, if someone could easily copy the innovative work during the patent life of the product.

However, the report also states, “While many of these concerns are valid, critics say they can be addressed, and that openness is far more important for patients’ drug safety reasons.“

Addressing the concerns:

To address the above concerns the EMA has reportedly separated clinical data into three categories:

  • Commercially confidential information.
  • Open-access data that doesn’t contain patients’ personal information.
  • Controlled-access data that will only be granted after the requester has fulfilled a number of requirements, including signing of a data-sharing agreement.

However experts do also reiterate, “Risks regarding data privacy and irresponsible use cannot be totally eliminated, and it will be a challenge to accommodate diverse expectations across the scientific and medical community. However, the opportunity to benefit the health of individuals and the public must outweigh these concerns.”

Some laudable responses:

Amidst mega attempts to thwart the move of EMA towards CT data transparency surreptitiously, there are some refreshingly good examples in this area, quite rare though, as follows:

  • As revealed by media, GlaxoSmithKline (GSK) has recently announced that it would share detailed data from all global clinical trials conducted since 2007, which was later extended to all products since 2000. This means sharing more than 1,000 CTs involving more than 90 drugs. More recently, to further increase transparency in how it reports drug-study results, GSK reportedly has decided to disclose more individual patient data from its CTs. GSK has also announced that qualified researchers can request access to findings on individual patients whose identities are concealed and confidentiality protected.The company would double the number of studies to 400 available by end 2013 to researchers seeking data of approved medicines and of therapies that have been terminated from development.
  • Recently Canada reportedly announced the launch of Canadian Government’s new public database of Health Canada-authorized drug CTs. It is believed that providing access to a central database of clinical trials is an initial step that will help fill an existing information gap as the government works to further increase transparency around CTs.
  • The well-known British Medical Journal (BMJ) in one of its editorials has already announced, “BMJ will require authors to commit to supplying anonymised patient level data on reasonable request from 2013.”

All these are indeed laudable initiatives in terms of ensuring long term drug safety and efficacy for the patients.

Conclusion:

It is quite refreshing to note that a new paradigm is emerging in the arena of CT data transparency, for long-term health interest of patients, despite strong resistance from powerful pharmaceutical trade bodies, as reported in the international media. This paradigm shift is apparently being spearheaded by Europe and Canada among the countries, the global pharma major GSK and the medical Journal BMJ.

A doubt still keeps lingering on whether or not independent expert panels will indeed be given access to relevant CT data for meaningful impartial reviews of new drugs, as the issue, in all probability, would increasingly be made to get embroiled in further controversy.

Moreover, if the innovator companies’ often repeated public stand – “patients’ interest for drug efficacy and safety is supreme” is taken in its face value, the veiled attempt of thwarting transparency of CT Data, with an utterly bizarre strategy, by the lobbyists of the same ‘patient caring’ constituent, can indeed be construed as a poignant moment, now frozen in time, in the history of drug development for mankind.

Be that as it may, to resolve this problem meaningfully and decisively, I reckon, a middle path needs to be carefully charted out between reported thwarting moves by pharma lobbyists and the embroiled controversy on the burning issue.

Thus, the final critical point to ponder:

Would the commerce-driven and cost-intensive pharma innovation also not be in jeopardy, affecting patients’ interest too, if the genuine concerns of the innovator companies over ‘CT Data Protection’ are totally wished away?

Beyond ‘The Magic Moment’ of New Drug Marketing Approval

Posted on by

“Uncontrolled clinical trials are causing havoc to human life. There are so many legal and ethical issues involved with clinical trials and the government has not done anything so far.”

This is exactly what the Supreme Court of India observed while responding to a Public Interest Litigation (PIL) on the subject in January 2013.

While Indian regulators with the active intervention of the Supreme Court are trying to grapple with, besides others, the basic ‘human rights’ aspect of the Clinical Trial (CT), many countries in different parts of the world are moving much ahead at a brisker pace. They have started thinking and putting in place more patient centric newer drug approval systems and also, in tandem, hastening the process of bringing new drugs to the market.

Current general scenario in CT:

Currently, after pre-clinical studies and before applying for regulatory approval, a new drug has to be tested on volunteers in randomized studies to prove its efficacy and safety on patients. Relatively short duration of new drug trials can hardly establish long-term safety and efficacy, which are now arrived at through extrapolation of data collected during CT period.

It is worth noting, the overall situation changes dramatically after launch of these products, as their usage expands from a relatively smaller number of CT volunteers to millions of real-world patients.

In a situation like this, unrealistic expectation of patients’ safety in perpetuity based primarily on extrapolation of very limited CT data is being increasingly questioned today.

That is why, on going post-marketing surveillance, which is also known as a Phase IV CT, is considered as a much more effective process to gauge relative superiority of the drug against the existing ones in terms of both efficacy and safety on a longer term.

That said, today one reads and hears umpteen number of accusations for almost lack of any meaningful response on the part of the pharmaceutical companies, in general, towards revelations of post-marketing surveillance data. This could, in turn, expose the patients to various types of risks, including wasteful healthcare expenditure.

The ‘Magic Moment’ in the present regulatory process:

A recent paper highlights a single “Magic Moment” between pre and post-licensing processes in the current drug-approval model in many countries. In this system, the use of a drug is tightly controlled in a narrowly defined pre-licensing population. Thus, CTs are also conducted on such pre-defined and relatively homogeneous volunteers, who are generally free from complicating conditions.

However, after ‘The Magic Moment’ of marketing approval, a large number of heterogeneous patient population, with many of them on multiple therapy, also use these new products in uncontrolled settings. Situations as these had led to post-marketing major drug withdrawals like, Vioxx and Avandia due to patients’ safety.

These grave concerns have led to a strategic shift in the drug regulatory approval scenario throwing open new ideas in the drug approval process.

Adaptive Licensing:

To find the right answer to this vexing issue the drug regulators in many countries are  reportedly seriously contemplating to imbibe a process that will continuously help analyzing information through ongoing post-marketing surveillance data. Continuous medical data analysis like this will enable the regulators to modify their earlier decisions on marketing approval and also medical reimbursements related to pricing reasons.

This new process is called ‘Adaptive Licensing (AL)’, which is expected to benefit the overall healthcare system, by not allowing medical reimbursement of treatments with those drugs, which will provide negligible benefit over existing low cost therapies.

Difference between current mechanism and AL:

According to a ‘Health Canada’ paper titled, “The Path to Adaptive Drug Regulation”, the difference between the two is as follows:

Current system:

As explained above, post-licensing i.e. after ‘The Magic Moment’ of regulatory approval, treatment population grows rapidly and treatment experiences do not contribute to evidence generation.

Adaptive Licensing:

After initial license, treated patients grow more slowly due to regulatory restrictions. Patient experience is captured to contribute to real-world information. The marketing license is also modified accordingly from time to time.

Most desirable for many drugs:

Experts in this field opine that AL will help bringing in alignment of all required processes so important for a new drug seen from patients’ perspective like, R&D, regulatory approval and market access with the active involvement of all stakeholders like, the pharmaceutical companies, the drug regulator, payors/insurance companies and also the researchers.

In the AL system, a transparent drug development process will provide enough data on risk-benefit profile of the concerned drug to satisfy the drug regulator for its quick marketing authorization on pre-determined types of patients.

Such approval will follow real-life monitoring of efficacy and safety for modification of the drug license accordingly, wherever and whenever required.

Thus, AL is expected to strike a right balance balance between timely access to new drugs for the patients and the need to evaluate real time evolving information on safety and efficacy leading to a well-informed patient centric decisions by the drug regulators.

A continuous regulatory evaluation and decision-making process:

AL intends to evaluate a drug through its entire life span.  It has been reported that during this long period, clinical and other data will “Continue to be generated on the product through various modalities, including active surveillance and additional studies after initial and full licensing. The artificial dichotomy of pre vs. post licensing stages (‘The Magic Moment’) will be replaced by graded, more tightly managed, but more timely and potentially more cost-effective market entry and market stability.”

Not necessary for all drugs in the near term:

It is worth noting that AL system may not perhaps be required for all pharmaceutical or biologic products and will not totally replace the current system of drug licensing process, at least in the near term.

AL process may immediately be followed only for those products with a favorable risk-benefit drug profile as demonstrated in the initial data and there is a robust reason for early market entry of this drug to meet unmet needs, simultaneously with ongoing studies.

The ‘Magic Moment’ freezes in India…in perpetuity:

As per the Drugs and Cosmetics Act of India, after obtaining drug marketing approval from the regulators, concerned pharmaceutical companies are required to follow the pharmacovigilance system in the country to own the responsibility and liability of the drugs as enunciated in the Schedule Y of the Act. Unfortunately, this is hardly being followed in India, ignoring patients’ safety blatantly.

With the plea that most products launched in India are already being marketed in many developed markets of the world, the concerned companies prefer to depend on clinical experiences in those markets. This attitude totally bypasses the regulatory requirement to follow a robust pharmacovigilance system in India. Indian drug regulators also do not seem to be much concerned about this important patients’ safety related requirements, very surprisingly not even for biosimilar drugs.

However, the current ground realities are quite different. As we witness today, there does not seem to be much difference in time between international and India launch of innovative products. Thus, the argument of gaining medium to long-term experience on safety and efficacy from international data related to these drugs, does not seem to hold any water at all.

On the contrary, some drugs withdrawn from the international markets on safety grounds are still available in India, despite ire and severe indictment even from the Indian Parliamentary Standing Committee.

In a situation like this, AL process of Marketing approval for selected newer and innovative drugs may be considered by the Indian Drug Regulators, just not to be more patient centric, but also to help evaluating  pricing decisions of innovative drugs failing to demonstrate significantly better treatment outcomes as compared to the existing ones.

A recent example of AL:

One of the latest drugs, which reportedly will undergo such regulatory scrutiny of USFDA is Tacfidera (dimethyl fumarate) used for the treatment of multiple sclerosis, approved in April 2013 and costing US$ 54,900 per patient per year.  Interestingly, Tacfidera, before the drug can find itself on a formulary, will need to demonstrate its effectiveness in the real world.

The report indicates, “the first six months after a drug launch are always about educating payers about its benefits, and while most large payers are likely to make a decision to reimburse the drug in the next twelve months, data collection will continue and changes in policies might be made at a later date.”

Thus, in the years ahead, whether a new drug will become a blockbuster or not will very largely be decided by the ongoing real world data. If the promise of a drug diminishes at any point of time through clinical data, it will certainly going to have consequential financial and other adverse impacts.

Another interesting recent development:

Under new pharmacovigilance legislation in Europe, the European Medicines Agency has reportedly announced the list of over 100 drugs that soon will bear the “black triangle” logo. This initiative is directed to encourage both the doctors and patients to report side effects to enable close monitoring of drug safety.

Criteria to include drugs under additional monitoring are:

  • Medicines authorized after January 1, 2011 that contain a new active substance.
  • Biologics for which there is limited post-marketing experience.
  • Medicines with a conditional approval or approved under exceptional circumstances.
  • Medicines for which the marketing-authorization holder is required to carry out a post-authorization safety study (PASS).
  • Other medicines can also be placed under additional monitoring, based on a recommendation from the European Medicines Agency’s Pharmacovigilance Risk Assessment Committee (PRAC).

Conclusion:

Global regulatory experts do believe that in the concept of AL, there are still some loose knots to be tightened expeditiously to make it a fully implementable common drug marketing authorization process.  Appropriate pilot projects need to be undertaken in this area to establish beyond any doubt that AL will be decisively more preferable to the current regulatory process.

As and when AL will become the preferred drug-licensing pathway across the world, it is expected to offer greater real benefits of new drug development to the patients for their optimal use at an affordable price.

That said, some other experts do opine as follows:

“No matter how fast the authorization process operates, the merits of innovation will not be felt until they reach patients. And the barrier between authorization and patient access remains, in most of Europe, the issue of reimbursement.”

While all these are fast developing in the global CT scenario, in the jangle of Clinical Trials‘ in India, ‘Adaptive Licensing’ has still remained a critical missing ingredient even to encourage a wider debate.
