Antimicrobial Resistance: A Recent Perspective

On January 23, 2018, at the World Economic Forum in Davos, Switzerland – the first independent analysis of pharmaceutical industry efforts to tackle antibiotic drug resistance, was published by the Netherlands based Access to Medicine Foundation.

The issue of Antimicrobial Resistance (AMR) was brought under focus by the World Economic Forum (WEF) not for the first time at Davos in 2018. Its 2013 Annual Report on global risks, also underscored the gargantuan health hazard that AMR poses to mankind. It said, we live in a bacterial world where we will never be able to stay ahead of the mutation curve. A test of our resilience is how far the curve, we allow ourselves to fall behind. It’s indeed a profound statement!

In that sense, the AMF analysis is important. More so, when the global population is virtually at the threshold of facing a situation very similar to pre-antibiotic era, where even a common infection used to pose threat to a life. And now, a fast-developing AMR to many effective antibiotics or even super-antibiotics, are making them almost redundant in many serious conditions. Consequently, around 700,000 people die every year only due to antimicrobial resistance, the world over.

The World Health Organization (WHO) also reiterated its grave concern in this area by a news release on September 20, 2017. It cautioned, “Antimicrobial resistance is a global health emergency that will seriously jeopardize progress in modern medicine.” Against that backdrop, in this article, I shall dwell on some latest developments in this area, both globally and also in India.

Dire need for newer antibiotics – but dry R&D pipeline:

At the very outset, let me flag another critical area that is intimately related to this concern. An article titled, “Where Are the Antibiotics?”, published by the AARP Foundation adds more to this growing concern. It writes, in an era when many breakthrough innovative drugs are curing some of our most deadly afflictions, the quest for meeting the unmet medical needs, seems to have shifted away from development of critically needed breakthrough antibiotics to effectively address AMR, for various reasons.

The author further highlighted that between the time penicillin was discovered in 1928, and the 1970s – 270 antibiotics were approved – a robust arsenal of powerful drugs that kept almost all bacterial infections at bay. However, since then, research into new antibiotics has declined dramatically. Today, just five of the top 50 big drug companies are reportedly developing innovative antibiotics – the article reiterates.  Nevertheless, some recent developments in this area can’t be ignored, either, which I shall touch upon in this discussion.

Global initiatives for a multi-pronged concerted action:

It is understandable that there are no magic bullets to address the fast-growing menace of AMR. It calls for a multi-pronged strategy with well-orchestrated concerted efforts for its effective implementation with military precision. Following are the three primary constituents who should lead from the front in the battle against AMR, as I reckon:

  • The world leaders
  • Each country, individually
  • Pharmaceutical industry, both global and local

The medical profession, including hospitals, nursing homes, the retail chemists and individual patients, also play a significant role to alleviate this problem, especially in India and other developing countries. But, I shall keep that as a subject for a separate discussion, altogether. Let me now touch-upon the first three constituents, one by one, as follows:

1. The world leaders’ initiative:

Realizing that failure to act on AMR will result in a global health and financial crisis, the world leaders met to address this growing menace. Accordingly, on September 21, 2016, the United Nations General Assembly (UNGA) passed a declaration aimed at slowing the spread of antibiotic-resistant superbugs. At this meeting in New York City, the top UN leaders successfully urged all governments to sign a political declaration to tackle the problem of AMR, both globally and in their respective countries. The joint declaration requires each country to develop a 2-year plan to protect the potency of antibiotics for both livestock and humans. The progress of the initiative for each country at the end of those 2 years will be evaluated. However, in this article, I shall focus only on the agreed human-specific actions, which include the following:

  • Antibiotics should be prescribed only when they are absolutely necessary
  • A massive education campaign about antibiotic resistance.
  • Greater monitoring of superbugs to understand the scope and magnitude of the problem.
  • Safeguarding current antibiotic stockpile.

The leaders suggested that people should be encouraged to help prevent the crisis from turning into a death sentence for millions, with the steps, such as:

  • Get available vaccines to prevent illness
  • Stop asking doctors for antibiotics when they have the cold or flu, as antibiotics treat neither
  • To urge their political leaders to commit to action in combating antibiotic resistance.

2. Country-specific initiatives:

In September 2016, just a year after the UNGA high-level meeting on AMR, an update by the United Nations Foundation reported that 151 countries out of 195 WHO member states have responded. The overall response includes the following, among others:

  • 85 percent of countries are developing or have developed National Action Plans (NAC).
  • 52 percent of countries have a fully developed plan with ‘One Health’ approach that seeks to unify human and veterinary medicine, agriculture, and food providers against the progression of AMR by reducing agricultural antimicrobial use.
  • 52 percent of Low and Middle-Income Countries (LMICs) have national-level measures in place on ‘Infection Prevention and Control (IPC)’ measures in human healthcare.

3. Pharmaceutical industry initiatives: 

I shall cite only the latest commendable developments in this area, as I see it. On Jan. 21, 2016 a document titled the ‘Declaration on Combating Antimicrobial Resistance’, was launched, again, as part of the World Economic Forum at Davos, Switzerland.

For the first time, 85 pharmaceutical, biotechnology, generic-drug, and diagnostic companies agreed on a common set of principles for global action to support antibiotic conservation and the development of new drugs, diagnostics, and vaccines. The document, outlining several critical measures the government and industry must take to increase antibiotic effectiveness worldwide, was also drafted and signed by nine industry associations spanning 18 countries.

Global progress assessment of AMR initiatives in 2018:

This brings me back to where I started from, while analyzing what happened in this regard a year after the above declaration was signed. On January 23, 2018, at the World Economic Forum in Davos, Switzerland – the first independent analysis of pharmaceutical industry efforts to tackle drug resistance, was revealed by the AMF. It found companies are developing new drugs, as well as dismantling the incentives that encourage sales staff to oversell antibiotics, setting limits on the concentration of antibiotics in factory wastewater released into the environment, and tracking the spread of superbugs.

In the AMR Benchmark, GSK and Johnson & Johnson lead among the largest research-based pharmaceutical companies. A separate ranking of manufacturers of generic antibiotics features Mylan, Cipla, and Fresenius Kabi Global, in the leading positions. While Mylan leads the generic medicine manufacturers, Entasis, reportedly, leads the biotechnology group. 

Twenty-eight antibiotics are in late stages of development:

The other key findings of the 2018 study include mention of 28 antibiotics that are in later stages of development, targeting pathogens deemed critical AMR priorities by the WHO, and/or US Centers for Disease Control and Prevention. However, only two of these 28 candidates are supported by plans to ensure they can be both made accessible and used wisely if they reach the market. Be that as it may, the benchmark finds room for all companies to improve in this space, the report indicated.

Some major initiatives in India:

The good news is, ‘The National Policy for Containment of Antibacterial Resistance’, with similar objectives, was put in place in India by the Directorate General of Health Services, Ministry of Health & Family Welfare, way back in 2011. Further, on March 20, 2015, to strengthen the surveillance of antimicrobial resistance (AMR) in the country, Indian Council of Medical Research (ICMR) had set up a National Antimicrobial Resistance Research and Surveillance Network (AMRRSN) to enable compilation of national data of AMR at different levels of health care.

Again, in February 2017, the Indian Council of Medical Research (ICMR)  has put a new ‘Treatment Guidelines for Antimicrobial Use in Common Syndromes’, to achieve the same objectives. Despite this, as many medical experts opine, a large number of General Practitioners (GP), including hospitals, nursing homes continued over-prescribing antibiotics. Alarmingly, considered as the last line of defense antibiotics by many doctors – Colistin and Carbapenem resistant infections have also been reported from several Indian hospitals. All this adds further fuel to the AMR fire.

Another matter of huge worry in India:

The February 04, 2018 article titled, ‘Threats to global antimicrobial resistance control Centrally approved and unapproved antibiotic formulations sold in India,’ published in the British Journal of Clinical Pharmacology, highlight serious hurdles for controlling antimicrobial resistance in India, which has had parliamentary investigations into the failures of the country’s drug regulatory system. The study was conducted by researchers from Queen Mary University in London, Newcastle University and Lakshya Society for Public Health Education and Research in Pune. Some of the key findings of the study are as follows:

  • Extensive use unapproved of fixed dose combination (FDC) antibiotics is contributing to the rising rate of AMR in India, which is already one of the highest in the world.
  • Out of the 118 of FDC antibiotics being sold in India, only 43 (36 percent) were approved by the CDSCO. These 118 antibiotic formulations are being sold in 3307 brand names and manufactured by 476 entities. Of these, 464 were Indian manufactures, and 12 were MNCs.

The authors recommend work on understanding why unapproved formulations are being prescribed by medical professionals.

Conclusion:

As the above AARP Foundation article highlights, like all living beings, bacteria constantly evolve to survive. While encountering a new antibiotic, they quickly find ways to evade it, and continue to live or exist. Some have even developed cell wall like virtually impregnable shields, as it were, keeping antibiotics out. Others pump antibiotics out when they get in. Several deadly bacteria have even devised ways to deactivate antibiotics.

The comments made in the article titled, ‘The Future of Antibiotics and Resistance,’ published by The New England Journal of Medicine (NEJM) on January 24, 2013, is also worth noting. It says, the converging crises of increasing resistance and collapse of antibiotic research and development are the predictable results of policies and processes we have used to deal with infections for 75 years. If we want a long-term solution, the answer is not incremental tweaking of these policies and processes. Novel approaches, based on a reconceptualization of the nature of resistance, disease, and prevention, are needed.

The bottom line still remains, AMR is a humongous threat to the global population, not just in India. While its awareness is gradually increasing, much more painstaking work remains to be done by all, both individually and collectively, to contain this global health menace. It’s our responsibility to protect the well-being of our future generations.

The Recent Ban On Irrational FDCs: History Repeats Itself

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

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

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

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

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

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

Would this ban have similar outcome?  

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

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

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

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

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

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

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

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

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

Some key events leading to the recent ban: 

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

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

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

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

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

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

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

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

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

Two Critical issues to address:

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

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

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

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

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

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

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

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

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

FDC approval must be hard evidence-based:

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

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

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

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

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

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

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

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

Conclusion:

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

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

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

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

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

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

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

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