Drug Quality Imbroglio And ‘Culture of Bending Rules’ in India

Posted on by

“Bottle Of Lies Exposes The Dark Side Of The Generic-Drug Boom” – re-emphasized the book, released in May 2019.  This confirms, the raging debate on the questionable quality of many generic drugs manufactured in India and involving several top domestic pharma companies, is a never-ending one. Numerous articles also ascribe many different reasons to this saga, leaving an overall impression – as if, blindfolded persons are trying to describe an elephant, touching and feeling different parts of the animal’s body, each at a time.

Let me illustrate the point with the Bloomberg article of January 31, 2019. It reported, “Culture of ‘Bending Rules’ in India Challenges U.S. Drug Agency.” And further commented: ‘The FDA confronts creative improvisation in the world’s largest generic-drug exporter.’ Curiously, according to the above report it seems to be a general belief among many, even within India.

This article will take into account the above apprehension – specifically raised against Indian drug manufacturers of both branded and non-branded generics. Accordingly, my focus will be on just three points – as possible causative factors for this critical issue:

  • Is it an India specific concern – thus related to ‘Indian cultural mindset’? or it’s a global issue, involving both Indian multinational drug manufacturers.
  • Is it a systematic attempt to create a perception bias against low-cost generic drugs, worldwide?
  • Are generic drug makers resorting to such unacceptable shortcuts due to increasing margin pressure?

Having deliberated these points, I shall try to outline a set possible remedial measures to address this issue in a holistic way, ensuring a win-win outcome. Let me first explore, whether or not this issue is specific to India, involving Indian drug manufacturers.

Is the issue India specific?

Is the issue of questionable quality of generic drugs, irrespective of whether they carry a brand name or not restricted to the shores of India? One can find its answer in the same report, as quoted above. A yearlong investigation by Bloomberg News into the generic-drug industry concluded, ‘FDA inspections at factories from West Virginia to China have found reason to doubt the data meant to prove drugs are safe and effective.’

One possible reason for such perception could be, since India is predominantly a branded generic market, voices decrying ‘questionable’ safety and efficacy of cheaper non-branded generic drugs, are too loud. Nevertheless, amidst all this, who’s who of branded generic manufacturers continue getting caught on the wrong foot by overseas regulators in the quality quagmire. Ironically, multinationals are also included in it.

Multinationals are also included in such quality quagmire:

There are several examples of non-compliance to requisite drug quality standards by multinational drug companies. Let me illustrate the point with an example that involves a top global pharma player.

The March 04, 2019 ‘Warning Letter’ of US-FDA for the Irungattukottai (Tamil Nadu) plant of Pfizer in India, clearly said: “Your quality system does not adequately ensure the accuracy and integrity of data to support the safety, effectiveness, and quality of the drugs you manufacture.”

This is not a solitary example of Pfizer’s generic hospital injectables manufactured in this plant. According to a media report dated July 17, 2018, twice before US-FDA had cited manufacturing and testing issues in this facility, containing 11 observations of the regulator, such as, workers “manipulated test sample weights to obtain passing results” for both batches of raw materials and finished product. It is a different matter that the company, later on, decided to close this plant for commercial reasons. Be that as it may, negative perception of generic drug quality is indeed an issue that needs to be addressed without further delay, holistically.

Studies have captured negative perception of generic drugs:

That this is a perception, has been well – elucidated along with its implications, in several studies. A few of which are as below:

A BMJ article concluded: “A significant proportion of doctors, pharmacists and lay people hold negative perceptions of generic medicines. It is likely these attitudes present barriers to the wider use of generics.” It further added, “Negative perceptions of medicine quality along with other drivers contribute towards choosing more expensive medicines in the private sector.”

Endorsing this point, yet another BMJ article inferred: “Negative perceptions of generic medicines and preferential promotion of branded medicines over generics by pharmaceutical companies could influence prescriber behavior and affect trust in healthcare provided in public services. To succeed, access to medicine programs need to systematically invest in information on the quality of medicines and develop strategies to build trust in healthcare offered in government health services.”

Again, in a separate survey of over 2700 physicians on perceptions of generic drugs, more than 23 percent of respondents expressed negative perceptions about their efficacy and nearly 50 percent. reported negative perceptions of generic drug quality. In the same survey, patients also expressed concerns that the lower cost of generics is associated with reduced medication quality.

Although, the above survey was conducted in the United States, the current situation in India, I reckon, is no different, but with one caveat. Here, preferential promotion of branded generic medicines over cheaper non-branded equivalents, by the respective drug manufacturers, could significantly influence prescriber behavior. Therefore, the question that follows: Is this perception-creation based on facts?

Is the negative perception fact-based?

Although, even the US-FDA clearly states that: ‘A generic medicine works in the same way and provides the same clinical benefit as its brand-name version”, I did try to find some conclusive evidence depicting brand name drugs are superior to their cheaper generic equivalents. While doing literature searches, two types of results emerged – there are studies that do not find any significant difference between generic drugs and their branded equivalents. At the same time, a few other studies do suggest that there is a difference between these two, but admitting that these studies are not conclusive. Let me give below examples of each.

No quality difference found between generic drugs and the branded variants: 

I shall quote here three studies, out of which one is India specific. The analysis reported in the above BMJ article, found that ‘the generic and branded variants of the medicines tested were of comparable quality.’

Another study, published by PLOS Medicine on March 13, 2019 also said, “In this study of 8 drug products conducted using 2 large US commercial insurance databases, we observed that use of generics provided comparable clinical outcomes as the brand products.”

An India specific researchon the same also reported, most generic and branded drug users believed that their drugs were effective in controlling their ailments with no significant difference in reported adverse effects and drug adherence.

Slightly different results were also reported with generics, but not conclusive:

One such study questioned, whether generic drugs are truly equivalent to the brand-name versions.This article was published on January 2019 by Harvard Health Publishing with the title, “Do generic drugs compromise on quality?”

This article quoted a Canadian study, published in the October 2017 issue of ‘Circulation: Cardiovascular Quality and Outcomes’, which found that patients who took generic versions of three different blood pressure medications in the months after the generic drugs became available saw increased rates of drug-related side effects.

Was it due to a perception bias?

To ascertain whether or not there is a perception bias, let us look into the following details of the same study along with its conclusion.

In this study, the researchers ‘looked at the numbers of emergency room visits and hospitalizations for 136,177 individuals ages 66 and over (60% of them women) who used any of three blood pressure medications: losartan (U.S. brand name Cozaar), valsartan (Diovan), and candesartan (Atacand). The investigators examined data for the periods 24 months before and 12 months after the generic versions of these medications went on the market. And found that before the generic versions became available, about one in 10 people taking the blood pressure drugs had to go to the emergency room or be hospitalized each month. In the month after each of the generics went into use, the rates of these adverse events went up: 8% for losartan, almost 12% for valsartan, and 14% for candesartan.’ The study authors commented, this might suggest performance differences between the brand-name and generic drugs.

However, analyzing this study, the Harvard article suggested further probe on the question: Did it result from quality problems with the generic versions of these medications or were there other factors that occurred in this time frame?

Another research, aimed at finding, whether patients are more adherent to generic statins than brand-name statins (lovastatin, pravastatin, or simvastatin) and whether greater adherence improves health outcomes, also concluded, “An 8% reduction in the rate of the clinical outcome was observed among patients in the generic group versus those in the brand-name group.” This also wasn’t a conclusive one, either.

Nevertheless, the key point of a ‘perception bias’, is captured in a separate study, where the researchers did find higher rates of psychiatric hospitalization for patients taking generic and AG escitalopram and sertraline, compared with those who initiated the brand-name product. Importantly, they noted that these outcomes were likely due to either residual confounding or generic perception bias.

No quality difference also found between branded and non-branded generics in India:

There are studies, which captured no quality difference between branded generics and non-branded generics in the country. One such India specific study concluded: “Quality of branded-generics is same as for their branded version. The study highlights the need to modify the drug price policy, regulate the markups in the generic supply chain, conduct and widely publicize the quality testing of generics for awareness of all stakeholders.”

Thus, so far, we have seen in this article that concern on quality of generic drugs is neither India specific, nor is it related to ‘Indian cultural mindset.’ And this is, undoubtedly, a global issue, involving both Indian and multinational drug manufacturers. There are also ample evidences available that a systematic attempt is being made to create a perception bias against low-cost generic drugs, worldwide. Let us now look at the third possible causative factor, as I listed above.

Is it due to margin pressure on generic drugs?

The answer to this question was deliberated in an article titled, ‘Generic drug makers feel pinch as prices crumble,’ published in the Financial Times on August 17, 2017. Quoting a top global financial analyst, it reported – global generic drug industry, where Indian manufacturers are major players,has maintained roughly 30 per cent operating margins over a long period of time, with improvements year on year. But, since last few years, there has been a margin degradation, which may possibly further go down – even lower than what it is today.

The article further highlighted, a round of consolidation among their main customers in the US: the wholesalers, have escalated the problem.  Many of these groups have clubbed together to form “mega buyers”, known as general purchasing organizations, that can command large discounts. Moreover, for the US market, another area of ‘concern’ is that the US-FDA has identified boosting competition in the generics market as one of its main priorities. As this reform opens up, it could squeeze the generic drug margins further.

Many envisage that intense cost cutting measures, could have transgressed in the drug quality assurance area, aggravating this issue. Although, it needs to be verified through credible studies, curiously, some signs of improvement in this area has recently been reported.

That said, there appears to be a strange coincidence between recent reports on Indian drug makers showing improvement in USFDA inspection outcomes and attempts to increase generic drug companies and some of their top executives slapped with price-fixing lawsuits in the U.S.This needs to be studied further.

The way forward:

The negative perception of generic drugs, in general, and non-branded generic drugs, in particular, is most likely a well-crafted business issue, rather than a genuine patient safety concern. It calls for an immediate two-pronged approach:

  • Vigorous awareness and educational campaigns on safety and efficacy of generic drugs targeted to patients, medical and paramedical professionals.
  • New regulatory measures, especially the following five:

- No pricing pressure or price control in any form of generic drugs

- Abolish brand names for generic drugs

- Make generic prescription compulsory to boost intense competition and thereby     reducing the price.

- Restrict the number of ingredients in FDC not more than two or three

- Make Uniform Code of Pharmaceutical Marketing Practices (UCPMP) mandatory.

Conclusion:

Thus, the questionable quality of generic drugs is not an India specific concern and involves both Indian multinational drug manufacturers. This is also evident from the analysis, as quoted above, that underscores, ‘FDA inspections at factories from West Virginia to China have found reason to doubt the data meant to prove drugs are safe and effective.’ Many studies have revealed that there is a systematic attempt to create a perception bias against low-cost generic drugs, worldwide.

A sequence of remedial measures, as described above, also include fostering competition, instead of introducing government controls on prices of generic drugs with stringent regulatory oversight being in place.

Thus, the so called ‘belief’ that the ‘culture of bending Rules’ is culpable for dubious generic drug quality in India, is more akin to a strong perception, prevailing in India, rather than based on any scientific analysis related to this issue. This ought to change with a well-coordinated intervention – for patients’ health interest sake.

USFDA ‘Import Bans’: The Malady Calls For Strong Bitter Pills

Posted on by

It is a matter of pride that Indian pharmaceutical industry is the second largest exporter of drugs and pharmaceuticals globally, generating revenue of around US$ 13 billion in 2012 with a growth of 30 percent (Source: Pharmexcil).

Though sounds awkward, it is a reality that India is a country where ‘export quality’ attracts a premium. Unintentionally though, with this attitude, we indirectly accept that Indian product quality for domestic consumption is not as good.

‘Export quality’ being questioned seriously:

Unfortunately today, increasing number of even ‘export quality’ drug manufacturing units in India are being seriously questioned by the regulators of mainly United States (US) and the United Kingdom (UK) on the current Good Manufacturing Practices (cGMP) being followed by these companies. In many instances their inspections are culminating into ‘Import Bans’ by the respective countries to ensure dug safety for the patients.

Are drugs for domestic consumption safe?

Despite intense local and global furore on this subject, Indian drug regulators at the Central Drugs Standard Control Organization (CDSCO), very strangely, do not seem to be much concerned on this critical issue, at least, not just yet. Our drug regulators seem to act only when they are specifically directed by the Supreme Court of the country.

A recent major incident is yet another example to vindicate the point. In this case, according to media reports of November 2013, the Drug Controller General of India (DCGI) has ordered the Indian pharma major Sun Pharmaceuticals to suspend clinical research activities at its Mumbai based bio-analytical laboratory, after discovering that the company does not have the requisite approval from the central government for operating the laboratory. The DCGI has decided not to accept future applications and will not process existing new drug filings that Sun Pharma has made from the Mumbai laboratory until the company gets an approval.

Considering the blatant violations of cGMP standards that are increasingly coming to the fore related to ‘export quality’ of drugs in India, after inspections by the foreign drug regulators, one perhaps would shudder to think, what could possibly be the level of conformance to cGMP for the drugs manufactured in India solely for the local patients.

This question comes up as the record of scrutiny on adherence to cGMP by the Indian drug regulators is rather lackadaisical. The fact that no such warnings, as are being issued by the foreign regulators, came from their local counterpart, reinforces this doubt.

USFDA ‘Import Bans’:

Be that as it may, in this article let me deliberate on this particular drug regulatory issue as is being raised by the USFDA and others.

It is important to note that in 2013 till date, USFDA issued ‘Import Alerts/Bans’ against 20 manufacturing facilities of the Indian pharmaceutical exporters, sowing seeds of serious doubts about the overall drug manufacturing standards in India.

The sequence of events post USFDA inspection: 

Let us now very briefly deliberate on the different steps that are usually followed by the USFDA before the outcomes of the inspections culminate into ‘Import Alerts’ or bans.

After inspections, depending on the nature of findings, following steps are usually taken by the USFDA:

  • Issue of ‘Form 483’
  • The ‘Warning letter’
  • ‘Import Alert’

Revisiting the steps: 

Let me now quickly re-visit each of the above action steps of the USFDA.

‘Form 483’: 

At the conclusion of any USFDA inspection, if the inspecting team observes any conditions that in their judgment may constitute violations of the Food, Drug and Cosmetic (FD&C) and other related Acts, a Form 483 is issued to the concerned company, notifying the firm management of objectionable conditions found during inspection.

Companies are encouraged to respond to the Form 483 in writing with their corrective action plan and then implement those corrective measures expeditiously. USFDA considers all these information appropriately and then determines what further action, if any, is appropriate to protect public health in their country.

The ‘Warning Letter’:

The ‘Warning Letter’ is a document usually originating from the Form 483 observations and results from multiple lacking responses to Form 483 requiring quick attention and action. It may be noted that higher-level USFDA agency officials and not the investigator issue the ‘Warning Letters’.

‘Import Alert/ Ban’:

‘Import Alerts’ are issued whenever USFDA determines that it already has sufficient evidence to conclude that concerned products appear to be adulterated, misbranded, or unapproved. As a result, USFDA automatically detains these products at the border, costing the related companies a lot of money. The concerned company’s manufacturing unit remains on the import alert till it complies with USFDA cGMP.

What happens normally?

Most of the USFDA plant inspections are restricted to issue of Form 483 observations and the concerned company’s taking appropriate measures accordingly. However, at times, ‘Warning Letters’ are issued,  which are also mostly addressed by companies to the regulator’s satisfaction.

Import Bans are avoidable: 

Considering the above steps, it is worth noting that there is a significant window of opportunity available to any manufacturing facility to conform to the USFDA requirements by taking appropriate steps, as necessary, unless otherwise the practices are basically fraudulent in nature.

The concern:

Currently, there is a great concern in the country due to increasing frequency of ‘Import Alerts’.  As per USFDA data, in 2013 to date, about 20 drug manufacturing facilities across India attracted ‘Import Alerts’ as against seven from China, two each from Australian, Canadian and Japanese units and one each from South African and German facilities.

The matter assumes greater significance, as India is the second-largest supplier of pharmaceuticals to the United States. In 2012, pharmaceutical exports from India to the US reportedly rose 32 percent to US$ 4.2 billion. Today, India accounts for about 40 percent of generic and Over-The-Counter (OTC) drugs and 10 percent of finished dosages used in the US.

Ranbaxy cases: ‘Lying’ and ‘fraud’ allegations: 

In September 2013, after the latest USFDA action on the Mohali manufacturing facility of Ranbaxy, all three plants in India of the company that are dedicated to the US market have been barred from shipping drugs to the United States. The magnitude of this import ban reportedly impacts more than 40 percent of the company’s sales. However, Ranbaxy has a total of eight production facilities across India.

This ‘Import Alert’ was prompted by the inspection findings of the USFDA that the Mohali factory of Ranbaxy had not met with the cGMP.

Other two plants of Ranbaxy’s located at Dewas and Paonta Sahib faced the same import alerts in 2008, and are still barred from making drug shipments to the US.

The import ban on he Mohali manufacturing facility of Ranbaxy comes after the company pleaded guilty in May 2013 to the felony (criminal) charges in the US related to drug safety and agreed to pay a record US$ 500 million in fines.

In addition, the company also faced federal criminal charges that it sold batches of drugs that were improperly manufactured, stored and tested. Ranbaxy also admitted to lying to the USFDA about how it tested drugs at the above two Indian manufacturing facilities.

Heavy consequential damages with delayed launch of generic Diovan:

The ‘Import Alert’ of the USFDA against Mohali plant of Ranbaxy, has resulted in delayed introduction of a cheaper generic version of Diovan, the blockbuster antihypertensive drug of Novartis AG, after it went off patent.

It is worth noting that Ranbaxy had the exclusive right to sell a generic version of Diovan from September 21, 2012. 

Gain of Novartis:

This delay will help Novartis AG to generate an extra one-year’s sales for Diovan. This is expected to be around US$ 1 billion, only in the US. This development prompted Novartis in July this year to raise its profit and sales forecasts accordingly.

Wockhardt cases: Non-compliance of cGMP

Following Ranbaxy saga, USFDA inspection of Chikalthana plant of Wockhardt in Maharashtra detected major quality violations. Second time this year USFDA noted 16 violations of cGMP in the company’s facility. Earlier, in July 2013, the Agency issued a ‘Warning Letter’ and ‘Import Alert’ banning the products manufactured at the company’s Waluj pharmaceutical production facility.

Moreover, in September 2013, Medicines and Healthcare Products Regulatory Agency (MHRA) had pulled the GMP certificate of the company’s unit based in Nani Daman, after an inspection conducted by the UK regulator showed poor manufacturing standards. 

Again, in October 2013, the MHRA withdrew its cGMP certificate for the Chikalthana plant of Wockhardt. This move would ban import of drugs into the UK, manufactured in this particular plant of the company.

However, MHRA has now decided to issue a restricted certificate, meaning Wockhardt will be able to supply only “critical” products from these facilities. This was reportedly done, as the UK health regulator wants to avert shortage of certain drugs essential for maintaining public health. The impact of the withdrawal of cGMP certificate on existing business of the company can only be ascertained once Wockhardt receives further communications from the MHRA.

Earlier in July 2013, MHRA had reportedly also imposed an import alert on the company’s plant at Waluj in Maharashtra and issued a precautionary recall for sixteen medicines made in this unit.

RPG Life Sciences cases: allegedly ‘Adulterated’ products: 

In June 2013, USFDA reportedly issued a ‘Warning Letter’ to RPG Life Sciences for serious violation of cGMP in their manufacturing plants located at Ankleshwar and Navi Mumbai.

USFDA investigators had mentioned that “These violations cause your Active Pharmaceutical Ingredients (APIs) and drug products to be adulterated …the methods used in, or the facilities or controls used for, their manufacture, processing, packing, or holding do not conform to, or are not operated or administered in conformity with cGMP.”

Strides Arcolab case: Non Compliance of cGMP

In September 2013, Strides Arcolab announced that its sterile injectable drug unit – Agila Specialties (now with Mylan) had received a warning letter from the USFDA after its inspection by the regulator in June 2013. However, Strides Arcolab management said, “the company was committed to work collaboratively and expeditiously with the USFDA to resolve concerns cited in the warning letter in the shortest possible time.”

USV case: allegation of ‘data fudging’: 

Recently, USFDA reportedly accused Mumbai-based drug major USV of fudging the data.

After an inspection of USV’s Mumbai laboratory in June 2013, the US drug regulator said the company’s “drug product test method validation data is falsified”. The USFDA has also reprimanded USV for not training its staff in cGMP.

Probable consequences: 

USFDA import bans and a similar measure by the UKMHRA would lead to the following consequences:

  • Significant revenue losses by the companies involved, till the concerned regulators accept their remedial actions related to cGMP.
  • Increasing global apprehensions about the quality of Indian drugs.
  • Possibility of other foreign drug regulators tightening their belts to be absolutely sure about cGMP followed by the Indian drug manufacturers, making drug exports from India more difficult.
  • Huge opportunity cost for not being able to take advantage from ‘first to launch’ generic versions of off patent blockbuster drugs, such as from Diovan of Novartis AG.
  • Indian patients, including doctors and hospitals, may also become apprehensive about the general quality of drugs made by Indian Pharma Industry, as has already happened in a smaller dimension in the past.
  • Opposition groups of Indian Pharma may use this opportunity to further their vested interests and try to marginalize the Indian drug exporters. 
  • MNCs operating in India could indirectly campaign on such drug quality issues to reap a rich harvest out of the prevailing situation.
  • Unfounded ‘foreign conspiracy theory’ may start gaining ground, prompting the Indian companies moaning much, rather than taking tangible remedial measures on the ground to effectively come out of this self created mess.

Conclusion: 

Repeated cGMP violations made by the Indian drug exporters, as enunciated by the USFDA, have now become a malady, as it were. This can be corrected, only if the reality is accepted without attempting for justifications and then swallowing strong bitter pills, sooner.

Thereafter, the domestic pharma industry, which has globally demonstrated its proven capability of manufacturing quality medicines at affordable prices for a large number of patients around the world and for a long time, will require to tighten belts for strict conformance to cGMP norms, as prescribed by the regulators. This will require great tenacity and unrelenting mindset of the Indian Pharma to tide over the crisis.

Any attempt to trivialize the situation, as indicated above, could meet with grave consequences, jeopardizing the thriving pharma exports business of India.

That said, any fraud or negligence in the drug quality standards, for whatever reasons or wherever these may take place, should be considered as fraud on patients and the perpetrators must be brought to justice forthwith by the DCGI, with exemplary punitive measures.
