Criticality of Drug Quality In The Moment Of Truth

Posted on by

When global health emergencies strike unannounced – in the scale and magnitude of new coronavirus, it shakes the health care system of all countries, in varying degree though, irrespective of the robustness of the economy. In such situation, the robustness of health care infrastructure, stringent manufacturing quality standards, operational flexibility for seamless sourcing of all drug ingredients in the required quantities, besides speed and agility of the delivery system – are put to the acid test.

Anytime readiness to effectively neutralize this crisis is of utmost importance. Accordingly, the key national goal should be to create a robust ‘whole’ that is much more than the sum total of each of each of the above factors – a sturdy ‘drug security system’ for the country. The most populous country of the world – China may have succeeded in building a 1,600-bed hospital coronavirus hospital in just 10 days, completing on February 05, 20120. But it is still looking for necessary drugs from other countries, such as the United States.

Curiously, China hasn’t yet disclosed its reason. More so, when the country is the top global supplier of Active Pharmaceutical Ingredients (API), including antiretroviral (ARV) drugs, along with India, according to the World Health Organization (W.H.O). This draws many to look at the general apprehension on the questionable quality of drugs that China, allegedly, produces. But, could this be the reason?

Nevertheless, regardless of inquisitiveness to know the reason, the question mark on its drug quality remains. And this is also not the risk-taking time for any nation, as it could possibly endanger lives of scores of the impacted population. The criticality of drug quality in ‘The Moment of Truth,’ such as, the new coronavirus emergency, can only be wished away at one’s own peril.

On the other hand, the confidence expressed in India, as we shall see below, in ‘drug security’, just based on adequate ARV drug availability appears to be coming from a different plane, although the drug quality issue is exactly the same in India, if not more concerning. From the above perspective, my today’s article will focus on this subject, purely based on available data, starting with the request of the Chinese authorities for ARV drugs from the United States.

Chinese request for ARV drugs:

‘U.S. Drugmakers Ship Therapies to China, Seeking to Treat Coronavirus – AbbVie, Gilead, others respond to Chinese authorities’ requests for antiviral drugs to test effectiveness against deadly respiratory illness.’ This was reported by The Wall Street Journal (WSJ) on January 27, 2020. It goes without saying that these antiviral drugs also include Anti-Retrovirals (ARVs).

AbbVie Inc. and Johnson & Johnson  are among the drug makers that have begun shipping drugs approved to treat HIV, while Gilead Sciences Inc. is exploring whether it should send an antiviral therapy it is developing.

It isn’t known whether the drugs would be able to help contain the explosion of respiratory virus infections sweeping the country or provide relief to infected patients. Chinese authorities have requested the shipments to test the drugs’ effectiveness in containing the new coronavirus, the report added.

An intriguing difference between India and China:

Interestingly, China is looking for sourcing some of these ARV drugs from the United States and not from India, either – one of the top producers of these drugs, as W.H.O reported.

In contrast, according to an Indian report of February 04, 2020: ‘Leading domestic drug companies have said they are ready with supply of anti-retrovirals (ARVs) that seem to work in treating the novel coronavirus (2019-nCoV).’

As I said earlier, although, China hasn’t yet specified the reasons behind their decision on ARV drug import from the United States, but could it have any link on the internal general apprehension of these drugs quality, safety and effectiveness?

Acknowledging for a moment that this is global allegation on Chinese drugs, in general. So is regarding India, as we shall see below. Then where does India stand on this score, especially in view of the confidence with ARV drugs, as exhibited in the above media report from India? That said, the logical question that surfaces now – why is the request for ARV drugs?

Why ARV drugs?

Although W.H.O said that there is ‘No known effective treatments’ for new coronavirus, as yet, various reports do indicate the use of ARV drugs in the treatment of 2019-nCoV:

  • A combination of flu and HIV medications are helping treat severe cases of the new coronavirus in Thailand.
  • Chinese health officials are already administering the HIV and flu drugs to fight the coronavirus, but the combination of the three together in a cocktail seemed to improve the treatment.

The Scientist, on February 02, 2020 reported that large doses of the flu drug oseltamivir combined with HIV drugs lopinavir and ritonavir, reportedly, improved the conditions of several patients in Bangkok, Thailand.

Global dependence on Chinese and Indian generic drugs:

About 80 percent of the Active Pharmaceutical Ingredients (APIs), including many ARVs, which are used for manufacturing of drug formulations in the United States are said to come from China and other countries like India. This appeared in the article titled, ‘U.S. Dependence on Pharmaceutical Products From China,’ published by the Council on Foreign Relations (CFR) on August 14, 2019.

India’s dependence on Chinese APIs:

Latest statistics from Directorate General of Commercial Intelligence and Statistics tabled in the Parliament show that in 2017-18, Indian imports of APIs and drug intermediates from China increased to 68.36 per cent. The same at 67.56 per cent in 2018-19, still remained the largest share in total Indian imports, with the overall India’s dependence on imports going up by 23 per cent from 2016-17 to 2018-19.

As reported in the media on November 22, 2019, India’s national strategies, such as, “2015 – Year of Active Pharmaceutical Ingredients” or ‘Make in India’ campaign, to promote indigenous means of production continue to be relegated on paper. Even, the current National Security Advisor had warned that Chinese dependence on API can be a national security threat.

According to the Department of Pharmaceuticals (DoP), Chinese API imports are due to economic considerations, which are essentially cheaper and more cost-effective for the Indian drug manufacturers, the above report highlighted.

Against this backdrop, the above local media report indicating, leading domestic drug companies are ready to supply anti-retrovirals (ARVs), may invite more questions than answers. Added to this come the critical quality issues with drugs manufactured in China and India.

Quality issues with Chinese drugs:

Credible documents highlight, as China’s pharmaceutical industry is not effectively regulated by the Chinese government, its regulatory apparatus is inadequately resourced to oversee thousands of Chinese drug manufacturers. Even if Beijing made such oversight a greater priority. This has resulted in significant drug safety scandals.

Although, the drug quality related concerns seem to be even more related to India, the drug industry of the country, reportedly, remains in a denial over most of such charges involving drug-quality.

India tops with the most quality related FDA warning letters in 2019:

The author of the above article reiterates, ‘Americans are expecting India, which supplies a significant percentage of the finished drug supply in the U.S., to get its act together to improve the quality of the medicines it makes, I am afraid they will be waiting a long time for that to happen. The only solution is for American lawmakers to enact new regulations focused on holding those who intentionally put public health at risk to account.’

To avoid ‘your-opinion-versus-my-opinion’ type of a debate with this article, let us look at some hard facts. These are from the ‘warning letters’ on drug quality, issued to various pharma companies, across the world, by the USFDA’s Center for Drug Evaluation and Research (CDER). The details were well captured in an article, titled ‘The country with the most FDA warning letters in 2019,’ published by Pharma Manufacturing on January 20, 2020.

Some key CDER findings:

As I consider, the top three CDER findings may be summarized as follows:

  • In 2019, CDER issued dozens warning letters for manufacturing issues to pharma companies outside the U.S. One country in particular – India – received the highest number of letters.
  • CDER’s office of Manufacturing Quality Letters issued 43 letters to companies outside of the U.S. Of those letters:

-   20 were aimed at facilities in India.

-   With 11, China received the second most manufacturing quality warning letters.

-   The rest of the letters were distributed among plants in Europe, Costa Rica, Singapore, Turkey and others.

  • The data from CDER shows that India has the poorest rate of FDA inspections with acceptable outcomes (83 percent) — much lower than China (90 percent) and the U.S. (93 percent).

Conclusion:

Today, a host of effective drugs and vaccines are available to treat a number of both non-infectious and infectious ailments, including many life-threatening viral diseases. However, the effectiveness of these medicines in treating such diseases, as well as many other illnesses, gets significantly compromised by questionable quality and distribution of these medicinal products. Even way back, a similar concern was deliberated in an article captioned, ‘Substandard drugs: a potential crisis for public health’, published in the British Journal of Clinical Pharmacology (BJCP), on November 29, 2013..

It may ordinarily remain undetected, sans stringent and wide-scale regulatory scrutiny. Additionally, a number of involved countries still remain in a denial mode. It’s also a fact, several governments may not have wherewithal for the same, particularly when the manufacturing units are too many, such as in China and India.

However, when a critical national health emergency strikes, unannounced, like the new coronavirus, the moment of truth dawns. Obviously, the national governments would want to be risk averse and prefer sourcing the best of drugs, to rapidly contain the spread of the disease, saving more lives. It’s not difficult to fathom, either, any country is unlikely to admit this reality, in public, even while taking measures for the same.

China’s sourcing of ARV and other drugs from the United States may or may not be due to the drug quality reasons. Nonetheless, I reckon, the criticality of drug quality issues can possibly be best realized, mostly when the ‘Moment of Truth’ arrives. Unannounced! Just like a bolt from the blue!

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

Posted on by
Reply

“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.

“Make in India…Sell Anywhere in The World”: An Indian Pharma Perspective

Posted on by

In his Independent Day speech from the ramparts of the Red Fort on August 15, 2014, Indian Prime Minister Modi gave a clarion call to all investors of the world, “Come, make in India”, “Come, manufacture in India”, “Sell in any country of the world, but manufacture here”.

The Prime Minister did not stop there. In his inimitable style, following it through on September 25, 2014 he gave an official status to ‘Make in India’ slogan and launched a global campaign.

“My definition of FDI for the people of India is First Develop India. This is also a responsibility for the people of India,” he further clarified.

An Indian perspective:

If I juxtapose this vision of the Prime Minister in the Indian pharmaceutical industry perspective, one finds that many small, medium and large size local domestic manufacturers are currently manufacturing drugs not just for the domestic market, but are also exporting in large quantities to various countries of the world, including, North America, South America and Europe.

The United States (US) is one of the most critical markets for majority of the Indian drug exporters. This transaction was taking place without any major regulatory hitches since quite some time. Unfortunately, over the last few years, mostly the Federal Drug Administration of the US (USFDA) and the United Kingdom (UK)’s Medicines and Healthcare Products Regulatory Agency (MHRA) have started raising serious doubts on the quality of medicines manufactured in India, making a significant impact on the drug exports of the country.

Most of these quality issues are related to ‘Data Integrity’ in the dug manufacturing and its documentation processes.

The impact:

According to industry data, in 2013-14, Indian drug exports registered the slowest growth in nearly the last 15 years. In this fiscal year, pharma exports of the country with a turnover of US$ 14.84 billion grew at a meager 1.2 percent. Pharmexcil attributed its reason to USFDA related regulatory issues and increasing global competition.

US accounts for about 25 percent of India’s pharma exports and its Federal Drug Administration (USFDA) has been expressing, since quite a while, serious concerns on ‘Data Integrity’ at the agency’s  previously approved production facilities of a large number of Indian pharma players.

The issue is causing not just a serious concern to USFDA and some other overseas drug regulatory agencies, but also posing a huge threat to future growth potential of Indian drug exports.

It is worth noting that Indian government had set an objective, in its strategy document, to register a turnover of US$ 25 billion for pharma exports in 2014-15. In all probability, it would fall far short of this target at the end of this fiscal, predominantly for related reasons.

Why is so much of ‘fuss’ on ‘Data Integrity’?

Broadly speaking, ‘Data Integrity’ in pharmaceutical manufacturing ensures that finished products meet pre-established specifications, such as, for purity, potency, stability and sterility. If data integrity is breached in any manner or in absence of credible data, the product becomes of dubious quality in the eyes of drug regulators.

Manufacturing related ‘Data Integrity’ is usually breached, when data from a database is deliberately or otherwise modified or destroyed or even cooked.

Over the last several years, ‘Data Integrity’ related issues in India are attracting enormous attention of both the USFDA and the MHRA, UK. As a result, concerned pharma manufacturing facilities are receiving Import Alerts/Warning Letters from the respective overseas drug regulators, refusing entry of those medicines mostly in the United States and some in the UK.

Recent warning letters:

Just over a year – from May 2013 to July 2014, around a dozen ‘Warning Letters’ have been sent to the Indian drug manufacturers by the USFDA on ‘Data Integrity’ related issue, as follows:

Recent ‘Warning Letter’ issued to: Date of issue
1. Marck Biosciences Ltd. 08. 07. 2014
2. Apotex Pharmachem India Pvt Ltd. 17. 06. 2014
3. Sun Pharmaceutical Industries 07. 05. 2014
4. Canton Laboratories Private Limited 27. 02. 2014
5. USV Limited 06. 02. 2014
6. Wockhardt Limited 25. 11. 2013
7. Agila Specialties Private Limited 09. 09. 2013
8. Posh Chemicals Private Limited 02. 08. 2013
9. Aarti Drugs Limited 30. 07. 2013
10. Wockhardt Limited 18. 07. 2013
11. Fresenius Kabi Oncology Ltd 01. 07. 2013
12. RPG Life Sciences Limited 28. 05. 2013

(Source: RAPS, 19 August 2014)

Another report states that USFDA has, so far, banned at least 36 manufacturing plants in India from selling products in the US.

Importance of US for Indian generic players:

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 sold there, come from India. Almost all of these are cheaper generic versions of patent expired drugs. Hence, India’s commercial stake in this area is indeed mind-boggling.

The ‘Data Integrity’ issue is not restricted to just US or UK:

A report quoting researchers led by Roger Bate, an American Enterprise Institute scholar and funded by the The Legatum Institute and the Humanities Research Council of Canada, concluded that many Indian pharma companies follow double manufacturing standards, as they are sending poor quality drugs to Africa compared to the same pills sold in other countries. This study was based on tests of 1,470 samples produced by 17 Indian drug manufacturers.

Besides India, the researchers took drug samples from pharmacies in Africa and middle-income countries, including China, Russia and Brazil.

According to this paper, the researchers found that 17.5 percent of samples of the tuberculosis therapy rifampicin sold in Africa tested substandard, which means the drug has less than 80 percent of the active ingredient than what it should otherwise. Against this number, in India, 7.8 percent of the medicine sampled was found substandard.

Moreover, Almost 9 percent of samples of the widely used antibiotic ciprofloxacin sold in Africa tested substandard, as compared to 3.3 percent in India.

Thorny issues around golden opportunities:

Much reported breach in manufacturing ‘Data Integrity’ detected at the manufacturing sites in India, are throwing fresh doubts on the efficacy and safety profile of generic/branded generic medicines, in general, produced in the country and more importantly, whether they are putting the patients’ health at risk.

A new analysis by the U.S. National Bureau of Economic Research pointed out some thorny issues related to ‘Data Integrity’ of drugs produced by the Indian pharmaceutical companies, which supply around 40 percent of the generic drugs sold in the United States, as stated above.

The researchers examined nearly 1,500 India-made drug samples, collected from 22 cities and found that “up to 10 percent of some medications contained insufficient levels of the key active ingredients or concentrations so low, in fact, that they would not be effective against the diseases they’re designed to treat.”

The report also highlighted that international regulators detected more than 1,600 errors in 15 drug applications submitted by Ranbaxy. The Bureau Officials commented that these pills were “potentially unsafe and illegal to sell.”

Frequent drug recalls by Indian pharma majors:

The above findings came in tandem with a series of drug recalls made recently by the Indian pharma companies in the US.

Some of the reported recent drug recalls in America, arising out of manufacturing related issues at the facilities of two well-known Indian pharma majors, which are going to merge soon, are as follows:

  • Sun Pharmaceuticals recalled nearly 400,000 bottles of the decongestant cetirizine (Zyrtec) and 251,882 of the antidepressant venlafaxine (Effexor) this May, because the pills failed to dissolve properly. The drugs were distributed by the drug maker’s US subsidiary Caraco Pharmaceutical Laboratories, but were manufactured in India.
  • In the same month – May, Ranbaxy recalled 30,000 packs of the allergy drugs loratadine and pseudo-ephedrine sulphate extended release tablets because of manufacturing defects in packaging.
  • In March, Sun Pharma recalled a batch of a generic diabetes drug bound for the US after an epilepsy drug was found in it. A patient discovered the error after noticing the wrong medication in the drug bottle.
  • Again in March, Ranbaxy recalled nearly 65,000 bottles of the statin drug atorvastatin calcium (Lipitor) after 20-milligram tablets were found in sealed bottles marked 10-milligrams. A pharmacist in the U.S. discovered the mix up.

Indian media reinforces the point:

Indian media (TNN) also reported that there is no quality control even for life-saving generic drugs and the government is apathetic on ensuring that the quality protocol of these drugs is properly observed.

This happens, as the report states, despite government’s efforts to push generic drugs, as they are more affordable. The report gave an example of a life-saving drug, Liposomal Amphotericin B, which is used to treat fungal infections in critically ill patients.

Are all these drugs safe enough for Indian Patients?

Though sounds awkward, it is a fact 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.

Unfortunately, in the recent years, increasing number of even ‘export quality’ drug manufacturing units in India are being seriously questioned, warned and banned by the overseas drug regulators, such as USFDA and MHRA, UK, just to ensure dug safety for the patients in their respective countries.

Taking all these into consideration, and noting increasing instances of blatant violations of cGMP standards and ‘Data Integrity’ requirements for ‘export quality’ drugs, one perhaps would shudder to think, what could possibly be the level of conformance to cGMP for the drugs manufactured solely for the consumption of local patients in India.

A cause of concern, as generic drugs are more cost effective to patients:

It has been widely recognized globally that the use of generic drugs significantly reduces out-of-pocket expenditure of the patients and also payers’ spending.

The findings of a study conducted by the Researchers from Brigham and Women’s Hospital (BWH), Harvard Medical School and CVS Health has just been published in the Annals of Internal Medicine on September 15, 2014. In this study the researchers investigated whether the use of generic versus brand name statins can play a role in medication adherence and whether or not this leads to improved health outcomes. The study concluded that patients taking generic statins were more likely to adhere to their medication and also had a significantly lower rate of cardiovascular events and death.

In this study, the mean co-payment for the generic statin was US$10, as against US$48 for brand-name statins. It is generally expected that the generic drugs would be of high quality, besides being affordable.

I deliberated on a related subject in one of my earlier blog posts of November 11, 2013 titled, “USFDA” Import Bans’: The Malady Calls For Strong Bitter Pills”.

Conclusion:

According to USFDA data, from 2013 onwards, 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.

Unfortunately, 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 the ‘Data Integrity’ issue, at least, not just yet.

In my view, ‘Data Integrity’ issues are mostly not related to any technical or other knowledge deficiency. From the “Warning Letters” of the USFDA to respective Indian companies, it appears that these breaches are predominantly caused by falsification or doctoring of critical data. Thus, it basically boils down to a mindset issue, which possibly pans across the Indian pharma industry, irrespective of size of operations of a company.

Indian Prime Minister’s passionate appeal aimed at all investors, including from India, to “Make in India” and “Sell Anywhere in The World”, extends to pharma industry too, both local and global. The drug makers also seem to be aware of it, but the ghost keeps haunting unabated, signaling that the core mindset has remained unchanged despite periodic lip service and public utterances for corrective measures by a number of head honchos.

Any attempt to trivialize this situation, I reckon, could meet with grave consequences, jeopardizing the thriving pharma exports business of India, and in that process would betray the Prime Ministers grand vision for the country that he epitomized with, “Make in India” and “Sell Anywhere in The World”.

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.
