Hype on “Superbug” – national pride – rational mind

Since around last fortnight Indian media of all types and forms, have been fiercely competing with each other to attract the ‘eye balls’ of the viewer/readers through ‘alarming’ news items starting from the situation in the J&K to the ‘rampant corruption’ involving the Commonwealth Games, with of course their usual (over)dose of sensationalism.

In a situation like this to prove ‘enough is JUST NOT enough’, as it were, on August 11, 2010, the well-known medical journal of repute “The Lancet” published a routine article, which further added to the ‘media sensationalism’ in India. The report highlighted that a new ALL antibiotics-resistant “Superbug” originating from Pakistan, appears to have taken its first life. This happened when a patient who was brought to a hospital in Belgium and died in June this year after having met with a car accident in Pakistan, where the diseased was infected by this ‘Superbug”.

This article in ‘The Lancet’ written by a team of international researchers including an Indian, elaborated that a new variety of enzyme named after India’s national capital New Delhi, called, “New Delhi Metallo beta lactamase” in short “NDM 1” turns any bacteria into a deadly “Superbug”, making it resistant to ALL types of antibiotics, leaving virtually no cure in sight.

It was also reported that this deadly “Superbug” has already reached the United Kingdom through patients who acquired it from the hospitals in India. The article reported that the deadly “Superbug” originated from the hospitals of Pakistan and India has the potential to precipitate serious health issues across the world.

“The New Delhi Superbug” was discovered even earlier:

This report generated a sharp reaction in India and from some of its authors regarding its authenticity. Some experts even termed this study as the ‘Western plot to undermine medical tourism in India’.

A leading daily of India reported, “Indian medical journal first documented Superbug”. It stated that that the first ever formal documentation of this ‘Superbug’ was made last year at the P.D. Hinduja National Hospital and Medical Research Centre located in Mumbai. This finding was published in the ‘Journal of the Association of Physicians in India (JAPI’) in March 2010. The reason for the emergence of the ‘Superbug’ was attributed to the ‘worrisome outcome of the indiscriminate use of antibiotics’.

“Unfair to blame the country for the ‘New Delhi’ superbug”:

Reacting to this article, Indian health authorities opined, “It is unfortunate that this new bug, which is an environmental thing, has been attached to a particular country.” The reasons being, “Several superbugs are surviving in nature and they have been reported from countries like Greece, Israel, the U.S., Britain, Brazil and there is no public health threat and no need to unnecessarily sensationalize it”. Some experts, however, feel, “such drug resistant bacteria is a matter of chance, is a global phenomenon and is preventable by sound infection prevention strategies which are followed in any good hospital.”

It has been reported that the ‘National Center for Disease Control of India’ is working on guidelines for appropriately recording these types of nosocomial (hospital acquired) infections.

“Superbug” Hype and Medical Tourism:
Many people of both India and Pakistan have felt since then that in absence of an effective response by the health authorities, especially, in India the fast evolving Medical Tourism initiatives, providing medical services ranging from complicated cardiovascular, orthopedic and cerebrovascular surgery to other life-threatening illnesses, may get adversely impacted.

The root cause and the ‘blame game’:

Experts have opined that overuse and imprudent or irrational use of antibiotics without any surveillance protocol are the root cause for emergence of such ‘Superbugs”, though some Indian parliamentarians have termed this article as the propaganda by some vested interests. It has been alleged that the study was funded by the Wellcome Trust and Wyeth, the two global pharmaceutical companies who produce antibiotics to treat such conditions, together with the European Union.

In this context it is worth mentioning that ‘The Lancet’ article in its disclosures says:

“Kartikeyan K Kumarasamy has received a travel grant from Wyeth… David M Livermore has received conference support from numerous pharmaceutical companies, and also holds shares in AstraZeneca, Merck, Pfizer, Dechra, and GlaxoSmithKline, and, as Enduring Attorney, manages further holdings in GlaxoSmithKline and Eco Animal Health. All other authors declare that they have no conflicts of interest.”

Such a situation has not been reported for the first time:

This type of situation has indeed some precedents. When ‘MRSA’ was reported for the first time, it caused similar scare. However, this time many experts feel that it is too early to conclude whether or not ‘NDM-1’ will eventually prove to be more dangerous than ‘MRSA’.

Several such “Superbugs”, as stated earlier, have already been reported from countries like Greece, Israel, USA, UK, and Brazil. However, as I know, in the battle against infectious diseases involving both the scientists and the bacteria, the later had always to succumb, in the long run.

‘NDM-1′, as well, perhaps will be no exception. All concerned MUST continue to make it happen, not by mere wishful thinking but by establishing a strong procedural mechanism to keep a careful vigil on the reasons for emergence of drug resistant bacterial strains in the country.

The World Health Organization (WHO) perspective:

On Saturday, August 21, 2010 the WHO commented, “while multi-drug resistant bacteria are not new and will continue to appear, this development requires monitoring and further study to understand the extent and modes of transmission, and to define the most effective measures for control”.
Conclusion:

The hype created and motives attributed by the media and the politicians over one such routine scientific papers published in a medical journal of international repute, in my view are unwarranted. There are built in systems within the scientific discourse for raising questions and even challenge any findings. Remarks made by one of the authors of the article to the media, perhaps added more fuel to the fire. Politicians seem to have joined the bandwagon to politicize even a benign medical issue captured in the said article. In an era where news items mean “sensationalism” and ‘politicization’ of most such news items is the order of the day, the civil society should be helped to understand the core issues behind all such raging debates.

Besides the reasons, as discussed earlier, attributed to repeated emergence of such “Superbugs”, one more issue I could foresee in today’s environment compared to the same in the past. This issue possibly lies in the shift in focus of pharmaceutical R&D from discovery of novel drugs for infectious diseases to discovery of drugs for non-infectious chronic illnesses like, metabolic disorders (diabetes), hypertension, cardiovascular diseases, psychiatric disorders, cancer, vaccines etc. This shift in the R&D focus has obviously been prompted by the tilt in the prevalence of the disease pattern towards the same direction.

Perhaps for this reason, one notices hardly any significant and novel molecules in the research pipelines of either global or local pharmaceutical companies to treat such antibiotic-resistant infections. It is understandebly not an ‘either/or’ situation. However, as we all know, in life-threatening conditions both types of drugs have their respective places to save precious lives. Let us ponder over it.

On ‘Patent Linkage’ – a rational argument on an emotive debate

WTO TRIPS Article 28.1a says that the member countries agree to ensure exclusive rights to patent holder for a specific time period. In case of India, like most other countries, this time period is for 20 years.During this period the member countries agree to prevent third parties from making, using, offering for sale the patented product without the owner’s consent.In India, during last twelve months, at least 4 patents were infringed by the local generic companies. All these cases are currently under litigation. No one at this stage will possibly be able to hazard a guess as to when will these cases ultimately get resolved. If it takes another two to three years to get the final verdict from the honourable High Courts, the revenue of the innovator companies who have already launched their patented products in India will get shaved off, at least for this period, leaving a very adverse commercial impact on them. There is a theoretical possibility that it may take even more time for the honourable High Courts to resolve these cases and during the remaining period of limited patent life of these products the cases may not get resolved, at all.

Moreover, in India there is no known strong deterrent for patent infringement. In absence of which, the opportunity to make significant commercial gain through patent infringement, on the pretext of extending benefits to patients could indeed be, many a times, difficult to resist. Media reports that the National Pharmaceutical Pricing Authority (NPPA) has raised huge demand in crores of rupees for overcharging the common man, flouting the drug pricing norms, by some of these large companies involved in patent infringement litigations, vindicates the point of their basic overall intention of significant commercial gain over extending pricing benefits to the patients. The moot question that follows is who is responsible to ensure the sanctity of the product patent system in India?

The prevailing situation warrants a strong regulatory system which could prohibit marketing approval of generic equivalents of patented molecules during their patent period.

The question that is often raised in this context is who exactly be held responsible for implementation of such a system in our country? While addressing this question one should realize that it is the Government in its entirety and not just the Patent offices or any particular ministry or ministries of the Governments is bound by the WTO TRIPS Agreement. Therefore, it is justifiably the responsibility of all Government departments/ministries to ensure that TRIPS obligations of the Government on proper enforcement of patent are properly met.

The process of granting marketing approval for patented molecules, in general, rests on the Ministry of Health (MoH) of WTO member states. Thus for WTO member states to meet TRIPS obligations effective communication between the MoH and the Patent offices of the country is absolutely essential. Such a system will help prevent approval of generic versions of patented molecules before expiration of the product patents.

Establishing this communication process will ensure that one department/ministry of the Government (say DCGI) does not impair the efforts of another Government department/ministry (say IPOs) to provide effective intellectual property protection as articulated in Article 28.1 of the WTO TRIPS Agreement.

This system will ensure that Health Regulatory Authorities do not, even unintentionally, undermine the commitment of the Government to conform to the TRIPS Agreement.

My experience of the last three years of post product patent regime in India prompts the need for establishing a “Patent Linkage” system without further delay, not only for effective patent protection but also to encourage innovators to get more involved and engaged in the process of innovation in India.

Will India be the unique country if such a system of “Patent Linkage” is put in place? The answer is obviously ‘no’.

In the largest market of the global pharmaceutical industry, the USA, such a system exists. US FDA maintains a listing of pharmaceutical products known as the ‘Orange Book’. The soft copy of the ‘Orange Book’ is also available through internet at: http:/www.fda.gov/cder/ob/.

US FDA does not authorize marketing approval of generic versions of patented molecules listed in the ‘Orange Book’.

What then happens in the second largest market of the global pharmaceutical industry, the European Union (EU)? In the EU, sanctity of the product patent is ensured by granting 10/11 years data exclusivity. Thus, if any company intends to introduce a generic version of a patented molecule, it will have to generate its own sets of entire regulatory data through a very long and expensive process, which may take several years. Even after spending huge amount money and time towards generation of their own clinical data, there is no guarantee that such companies will be able to market the product without getting involved into expensive patent infringement litigation. Thus in the EU, the deterrent to make such an ambitious attempt is humongous.

Various types of ‘Patent Linkage’ system also exists in Australia, Canada, Mexico, Jordan, UAE, Singapore, China etc. While putting in place of such a system is reportedly in progress in countries like, Chile, Dominican Republic – Central America, Bahrain, Morocco, Oman etc.

To conclude, in my view, when the Government of India is the sole authority to grant product patents in India, it is the responsibility of the same Government to protect those patents through its Health Regulatory System i.e. DCGI’s office. I reckon, such a system already exists in India. The procedure of (‘Patent Linkage’) checking the patent status before granting marketing approval already exists in FORM 44, which is an application to the DCGI for grant of permission to import or manufacture a New Drug or to undertake clinical trial in India. In the first page of FORM 44 (available in the website of the DCGI) under ‘Particulars of New Drug’ in point 8, it seeks details of the ‘Patent Status of the drug’. Can this information be not effectively utilized to justifiably deny marketing approval of a generic version of a patented molecule during its patent life in India? If not, it is difficult to make out what purpose will the DCGI utilize this information for?

Thus in my view, the procedure to be followed for ‘Patent Linkage’ in India is already in place. There is hardly any need to reinvent this wheel either. The Health Regulatory Authority of India should now make this procedure work effectively in its obligation to adhere to the commitment of the national Government to honour Article 21.1 of WTO TRIPS Agreement.
