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.

Booming Sales Of Unapproved Drugs: Do We Need “Safe In India” Campaign For Medicines?

“To sin by silence when they should protest makes cowards of men”                      - Abraham Lincoln

Not just the Federal Drug Administration of the United States (USFDA), global concerns are being expressed regularly about the laxity of drug regulatory and clinical trial standards in India, exposing patients to health safety related risks.

The problem is significantly more with the Fixed Dose Combination (FDC) Drugs for various reasons. This is worrisome because; the domestic market for FDCs is very large and growing much faster, in sharp contrast to the western world. For example, in 2011-12 FDCs accounted for more than half of all NSAID and oral anti-diabetic drug sales, and one-third and one-fifth of anti-psychotic and anti-depressant/benzodiazepine sales, respectively, according to a recent study.  Both the domestic and multi-national pharma players market FDCs in India

Alarmingly, a plethora of FDCs unapproved by the drug regulators of India on their rationality, efficacy and safety, have flooded the domestic pharma market, in large quantities.

All such drugs are being actively promoted by the respective pharma players, widely prescribed by the doctors, openly sold by the chemists and freely consumed by the patients without any apprehension or having no inkling of the magnitude of the possible health hazards that such drugs might cause, both in short and long term.

Public health safety hazard arising out of this scenario does not seem to have ever been estimated by the Indian drug regulators, despite indictments even by the Parliamentary Standing Committee, nor is there any properly functional system in place to capture such data for meaningful analysis.

As the saying goes ‘better late than never’, a credible report on this menace has just been published on May 12, 2015 by independent experts, which I shall discuss in this article.

Is the situation out of control?

On the ground, the situation seems to be out of control of even the Central Drugs Standard Control Organization (CDSCO).

This is vindicated by a March 2013, written reply of the Minister for Health and Family Welfare, where the Government reportedly informed the Lok Sabha (the lower House of the Parliament) that in twenty three cases of new FDC, licenses have been granted by the State Licensing Authorities (SLAs) without the mandatory approval of the DCGI and action will be taken in all these cases.

However, no one seems to know, as yet, what action the Government has taken against those errant officials.

The latest investigative report on the criticality of the situation:

The May 12, 2015 issue of “PLOS Medicine” – a Peer-Reviewed Open-Access Journal, published the results of an investigation on CDSCO approval for and availability of oral FDC drugs in India from four therapeutic areas – analgesia (non-steroidal anti-inflammatory drugs (NSAIDs), diabetes (metformin), depression/anxiety (anti-depressants/benzodiazepines), and psychosis (anti-psychotics).

This study was done based on the Department Related Parliamentary Committee on Health and Family Welfare’s 2012 Report, stating that manufacturing licenses for large numbers of FDCs had been issued by state authorities without prior approval of the CDSCO in violation of rules, and considered that some ambiguity until 1 May 2002 about states’ powers might have contributed to this worrying consequences.

I shall also discuss the above Parliamentary Committee report in this article.

Booming sales of unapproved drugs: 

‘PLOS Medicine’ report highlighted the following:

A. They obtained information on FDC formulations approved between1961 and 2013 in each therapeutic area from the CDSCO.

B. FDC sales details were obtained for the period 2007 to 2012 from PharmaTrac database of drug sales in India. Over the five years included in the time-trend analysis, FDCs accounted for an increasing proportion of total sales volumes. By 2011–2012, FDCs accounted for more than half of all NSAID and oral anti-diabetic drug sales, and one-third and one-fifth of anti-psychotic and anti-depressant/benzodiazepine sales, respectively.

C. Of the 175 FDC formulations marketed in India in the therapeutic areas studied, only 60 (34 percent) were approved. 

Out of these, percentages of approved formulations are as follows:

-       80 percent of 25 marketed metformin FDC formulations

-       27 percent of 124 NSAID FDC formulations

-       19 percent of 16 anti-depressant/benzodiazepine FDC formulations

-       30 percent of 10 anti-psychotic FDC formulations

D. In 2011–2012, percentages of FDC sales volumes arising from unapproved formulations was:

-       43 percent for anti-psychotics

-       69 percent for anti-depressants/benzodiazepines

-       28 percent for NSAIDs

-       0.4 percent for metformin

E. Formulations including drugs of which use is banned or restricted internationally accounted for 13.6 percent and 53 percent of NSAID and anti-psychotic FDC sales, respectively.

F. While “ambiguity” in the rules prior to 2002 was advanced as a reason for some FDCs having been marketed without a record of central approval, the researchers identified no ambiguity, and in fact, following an amendment to the rules in May 2002 that extended the requirements on approval applicants, new FDCs continued to be marketed without a record of central approval.

The suggestions:

The ‘PLOS Medicine’ report concluded with the following suggestions:

Unapproved formulations should be banned immediately, prioritizing those withdrawn or banned internationally, and undertaking a review of benefits and risks for patients.

To ensure long-term safety and effectiveness of new medicines marketed in India, as well as transparency of the approval process, amendments in India’s regulatory processes and drug laws are called for. A review should be undertaken of the safety and effectiveness of FDCs currently available in India.

Indian lawmakers too pointed out this embarrassing regulatory laxity:

This saga of drug regulatory laxity in general and for the FDCs in particular, is continuing since quite a while. This is despite the fact that the Department Related Parliamentary Committee on Health and Family Welfare presented its 59th Report of 118 pages in total on the functioning of the Indian Drug Regulator – the Central Drug Standards Control Organization (CDSCO) in both the houses of the Parliament on May 08, 2012.

The report begins with a profound observation:

Medicines apart from their critical role in alleviating human suffering and saving lives have very sensitive and typical dimensions for a variety of reasons. Prescription drugs are the only commodities for which the consumers have no role to play. Nor are they able to make any informed choices, except to buy and consume whatever is prescribed or dispensed to them, because of the following reasons:

  • Drug regulators decide which medicines can be marketed
  • Pharma companies either produce or import drugs that they can profitably sell
  • Doctors decide which drugs and brands to prescribe
  • Consumers are at the mercy of external entities to protect their interests

The ‘Mission Statement’ of CDSCO is ‘Industry Oriented’ and not ‘Patient Focused:

Very interestingly, the lawmakers’ report highlights, citing the following examples, how out of line the ‘Mission Statement’ of CDSCO is, as compared to the same of other countries, by being blatantly industry oriented instead of safeguarding Public Health and Safety interests :

Drug Regulator

The ‘Mission Statement’

1.

CDSCO, India

Meeting the aspirations…. demands and requirements of the pharmaceutical industry.
2.

USFDA, USA

Protecting the public health by assuring the safety, efficacy, and security of human and veterinary drugs.
3.

MHRA, UK

To enhance and safeguard the health of the public by ensuring that medicines and medical devices work, and are acceptably safe.
4.

TGA, Australia

Safeguarding public health & safety in Australia by regulating Medicines…

Consequently, the Parliamentary Committee took a strong exception for such utter disregard and continued neglect of patients’ interest by the Drug Regulator of India. It recommended immediate amendment of the ‘Mission Statement’ of CDSCO incorporating in very clear terms that the existence of the organization is solely for the purpose of protecting the best interest of patients and their safety. It is needless to say, thereafter it would call for its stringent conformance with high precision.

A scathing remark against CDSCO:

The parliamentary Committee report made the following scathing remarks on CDSCO in its point 2.2:

“The Committee is of the firm opinion that most of the ills besetting the system of drugs regulation in India are mainly due to the skewed priorities and perceptions of CDSCO. For decades together it has been according primacy to the propagation and facilitation of the drugs industry, due to which, unfortunately, the interest of the biggest stakeholder i.e. the consumer has never been ensured.”

Allegation of possible collusion:

The report also deliberates not only on the utter systemic failure of CDSCO along with the DCGI’s office to enforce the drug regulations effectively, but also towards a possible collusion between CDSCO and the pharmaceutical industry to implement a self-serving agenda by hoodwinking the system. This is a very serious allegation, which needs to be thoroughly probed and the findings of which should be made public for everybody’s satisfaction.

The committee, therefore, felt that effective and transparent drug regulation, free from all commercial influences and callous enforcement of rules and laws, are absolutely essential to ensure safety, efficacy and quality of drugs keeping just one objective in mind, i.e., welfare of patients.

Do we need “Safe in India” campaign for drugs?

Do we need a well-hyped “Safe in India” campaign for drugs? Looking around, at least conceptually, the answer is probably ‘yes’…Seriously…I am not joking!

The reason being, despite scathing remarks of the Parliamentary Standing Committee in 2012, apparently no systematic enquiry has been undertaken by the CDSCO to ascertain the reason for continuation and the veracity of this menace, just yet.

A very significant number of unapproved medications still remain undetected by the drug regulators and continue to be abundantly available, frequently prescribed, openly sold and freely consumed by the patients without even an iota of doubt regarding possible health safety hazards that these prescription drugs might cause.

May 2015 ‘PLOS Medicine’ Report helps unraveling the underbelly of the drug regulatory scenario in India, along with its systemic decay, which fails to halt the possible serious health safety hazards that Indian patients are exposed to.

India’s image as an emerging ‘pharmacy of the world’ for cheaper generic drugs has already been dented with a number of ‘import bans’ from the US and UK for flouting the specified drug manufacturing quality standards.

The saga of ‘import bans’ for Indian drugs, together with this critical health safety related menace, probably necessitates an effective launch of a “Safe in India” campaign for medicines, in general, by the Government.

This initiative gains additional importance, as painstakingly developed reputation of the Indian drug exporters, including the largest domestic players, has now been dented. It needs to be revamped, sooner.

I addressed a related issue in my blog post of February 3, 2014, titled “FDA ‘Import Bans: Valuing Drug Supply Chain Security For Patients’ Safety.”

Conclusion:

Effective resolution of this critical issue demands high priority at the highest level of the decision making process of the Government, with commensurate sense of urgency.

Keeping that in mind, would it be a bad idea, if just like “Make in India” campaign of the Prime Minister; “Safe in India” campaign for medicines is also undertaken with equal gusto and monitored by the top echelon of the country’s rejuvenated governance machinery?

This initiative would probably help sending the very contextual ‘shape up or ship out’ signal to the drug regulators, both at the Center and also in the States to erase the prevailing menace for good.

In that process, it would eventually allay the public health safety concern with the ‘Made in India’ drugs, coming out of ‘Make in India’ campaign, not just in the country, but also beyond its shores.

The speed of action in this situation is the essence. Otherwise, the following golden words of wisdom as enunciated by Abraham Lincoln would keep haunting us, till the remedial measures taken by the Government become palpable on the ground:
