R&D: Is Indian Pharma Moving Up the Value Chain?

It almost went unnoticed by many, when in the post product patent regime, Ranbaxy launched its first homegrown ‘New Drug’ of India, Synriam, on April 25, 2012, coinciding with the ‘World Malaria Day’. The drug is used in the treatment of plasmodium falciparum malaria affecting adult patients.  However, the company has also announced its plans to extend the benefits of Synriam to children in the malaria endemic zones of Asia and Africa.

The new drug is highly efficacious with a cure rate of over 95 percent offering advantages of “compliance and convenience” too. The full course of treatment is one tablet a day for three days costing less than US$ 2.0 to a patient.

Synriam was developed by Ranbaxy in collaboration with the Department of Science  and Technology of the Government of India. The project received support from the Indian Council of Medical Research (ICMR) and conforms to the recommendations of the World Health Organization (WHO). The R&D cost for this drug was reported to be around US$ 30 million. After its regulatory approval in India, Synriam is now being registered in many other countries of the world.

Close on the heels of the above launch, in June 2013 another pharmaceutical major of India, Zydus Cadilla announced that the company is ready for launch in India its first New Chemical Entity (NCE) for the treatment of diabetic dyslipidemia. The NCE called Lipaglyn has been discovered and developed in India and is getting ready for launch in the global markets too.

The key highlights of Lipaglyn are reportedly as follows:

  • The first Glitazar to be approved in the world.
  • The Drug Controller General of India (DCGI) has already approved the drug for launch in India.
  • Over 80% of all diabetic patients are estimated to be suffering from diabetic dyslipidemia. There are more than 350 million diabetics globally – so the people suffering from diabetic dyslipidemia could be around 300 million.

With 20 discovery research programs under various stages of clinical development, Zydus Cadilla reportedly invests over 7 percent of its turnover in R&D.  At the company’s state-of-the-art research facility, the Zydus Research Centre, over 400 research scientists are currently engaged in NCE research alone.

Prior to this in May 14, 2013, the Government of India’s Department of Biotechnology (DBT) and Indian vaccine company Bharat Biotech jointly announced positive results, having excellent safety and efficacy profile in Phase III clinical trials, of an indigenously developed rotavirus vaccine.

The vaccine name Rotavac is considered to be an important scientific breakthrough against rotavirus infections, the most severe and lethal cause of childhood diarrhea, responsible for approximately 100,000 deaths of small children in India each year.

Bharat Biotech has announced a price of US$ 1.00/dose for Rotavac. When approved by the Drug Controller General of India, Rotavac will be a more affordable alternative to the rotavirus vaccines currently available in the Indian market. 

It is indeed interesting to note, a number of local Indian companies have started investing in pharmaceutical R&D to move up the industry value chain and are making rapid strides in this direction.

Indian Pharma poised to move-up the value-chain:

Over the past decade or so, India has acquired capabilities and honed skills in several important areas of pharma R&D, like for example:

  • Cost effective process development
  • Custom synthesis
  • Physical and chemical characterization of molecules
  • Genomics
  • Bio-pharmaceutics
  • Toxicology studies
  • Execution of phase 2 and phase 3 studies

According to a paper titled, “The R&D Scenario in Indian Pharmaceutical Industry” published by Research and Information System for Developing Countries, over 50 NCEs/NMEs of the Indian Companies are currently at different stages of development, as follows:

Company Compounds Therapy Areas Status
Biocon 7 Oncology, Inflammation, Diabetes Pre-clinical, phase II, III
Wockhardt 2 Anti-infective Phase I, II
Piramal Healthcare 21 Oncology, Inflammation, Diabetes Lead selection, Pre-clinical, Phase I, II
Lupin 6 Migraine, TB, Psoriasis, Diabetes, Rheumatoid Arthritis Pre-clinical, Phase I, II, III
Torrent 1 Diabetic heart failure Phase I
Dr. Reddy’s Lab 6 Metabolic/Cardiovascular disorders, Psoriasis, migraine On going, Phase I, II
Glenmark 8 Metabolic/Cardiovascular /Respiratory/Inflammatory /Skin disorders, Anti-platelet, Adjunct to PCI/Acute Coronary Syndrome, Anti-diarrheal, Neuropathic Pain, Skin Disorders, Multiple Sclerosis, Ongoing, Pre-clinical, Phase I, II, III

R&D collaboration and partnership:

Some of these domestic companies are also entering into licensing agreements with the global players in the R&D space. Some examples are reportedly as follows:

  • Glenmark has inked licensing deals with Sanofi of France and Forest Laboratories of the United States to develop three of its own patented molecules.
  • Domestic drug major Biocon has signed an agreement with Bristol Myers Squibb (BMS) for new drug candidates.
  • Piramal Life Sciences too entered into two risk-reward sharing deals in 2007 with Merck and Eli Lilly, to enrich its research pipeline of drugs.
  • Jubilant Group partnered with Janssen Pharma of Belgium and AstraZeneca of the United Kingdom for pharma R&D in India, last year.

All these are just indicative collaborative R&D initiatives in the Indian pharmaceutical industry towards harnessing immense growth potential of this area for a win-win business outcome.

The critical mass:

An international study estimated that out of 10,000 molecules synthesized, only 20 reach the preclinical stage, 10 the clinical trials stage and ultimately only one gets regulatory approval for marketing. If one takes this estimate into consideration, the research pipeline of the Indian companies would require to have at least 20 molecules at the pre-clinical stage to be able to launch one innovative product in the market.

Though pharmaceutical R&D investments in India are increasing, still these are not good enough. The Annual Report for 2011-12 of the Department of Pharmaceuticals indicates that investments made by the domestic pharmaceutical companies in R&D registered an increase from 1.34 per cent of sales in 1995 to 4.5 percent in 2010. Similarly, the R&D expenditure for the MNCs in India has increased from 0.77 percent of their net sales in 1995 to 4.01 percent in 2010.

Thus, it is quite clear, both the domestic companies and the MNCs are not spending enough on R&D in India. As a result, at the individual company level, India is yet to garner the critical mass in this important area.

No major R&D investments in India by large MNCs:

According to a report, major foreign players with noteworthy commercial operations in India have spent either nothing or very small amount towards pharmaceutical R&D in the country. The report also mentions that Swiss multinational Novartis, which spent $ 9 billion on R&D in 2012 globally, does not do any R&D in India.

Analogue R&D strategy could throw greater challenges:

For adopting the analogue research strategy, by and large, the Indian pharma players appear to run the additional challenge of proving enhanced clinical efficacy over the known substance to pass the acid test of the Section 3(d) of the Patents Act of India.

Public sector R&D:

In addition to the private sector, research laboratories in the public sector under the Council for Scientific and Industrial Research (CSIR) like, Central Drug Research Institute (CDRI), Indian Institute of Chemical Technology (IICT) and National Chemical Laboratory (NCL) have also started contributing to the growth of the Indian pharmaceutical industry.

As McKinsey & company estimated, given adequate thrust, the R&D costs in India could be much lower, only 40 to 60 per cent of the costs incurred in the US. However, in reality R&D investments of the largest global pharma R&D spenders in India are still insignificant, although they have been expressing keenness for Foreign Direct Investments (FDI) mostly in the brownfield pharma sector.

Cost-arbitrage:

Based on available information, global pharma R&D spending is estimated to be over US$ 60 billion. Taking the cost arbitrage of India into account, the global R&D spend at Indian prices comes to around US$ 24 billion. To achieve even 5 percent of this total expenditure, India should have invested by now around US$ 1.2 billion on the pharmaceutical R&D alone. Unfortunately that has not been achieved just yet, as discussed above.

Areas of cost-arbitrage:

A survey done by the Boston Consulting Group (BCG) in 2011 with the senior executives from the American and European pharmaceutical companies, highlights the following areas of perceived R&D cost arbitrage in India:

Areas % Respondents
Low overall cost 73
Access to patient pool 70
Data management/Informatics 55
Infrastructure set up 52
Talent 48
Capabilities in new TA 15

That said, India should realize that the current cost arbitrage of the country is not sustainable on a longer-term basis. Thus, to ‘make hay while the sun shines’ and harness its competitive edge in this part of the world, the country should take proactive steps to attract both domestic as well as Foreign Direct Investments (FDI) in R&D with appropriate policy measures and fiscal incentives.

Simultaneously, aggressive capacity building initiatives in the R&D space, regulatory reforms based on the longer term need of the country and intensive scientific education and training would play critical role to establish India as an attractive global hub in this part of the world to discover and develop newer medicines for all.

Funding:

Accessing the world markets is the greatest opportunity in the entire process of globalization and the funds available abroad could play an important role to boost R&D in India. Inadequacy of funds in the Indian pharmaceutical R&D space is now one of the greatest concerns for the country.

The various ways of funding R&D could be considered as follows:

  • Self-financing Research: This is based on:
  1. “CSIR Model”: Recover research costs through commercialization/ collaboration with industries to fund research projects.
  2. “Dr Reddy’s Lab / Glenmark Model”: Recover research costs by selling lead compounds without taking through to development.
  • Overseas Funding:  By way of joint R&D ventures with overseas collaborators, seeking grants from overseas health foundations, earnings from contract research as also from clinical development and transfer of aborted leads and collaborative projects on ‘Orphan Drugs’.
  • Venture Capital & Equity Market:  This could be both via ‘Private Venture Capital Funds’ and ‘Special Government Institutions’.  If regulations permit, foreign venture funds may also wish to participate in such initiatives. Venture Capital and Equity Financing could emerge as important sources of finance once track record is demonstrated and ‘early wins’ are recorded.
  • Fiscal & Non-Fiscal Support: Should also be valuable in early stages of R&D, for which a variety of schemes are possible as follows:
  1. Customs Duty Concessions: For Imports of specialized equipment, e.g. high throughput screening equipment, equipment for combinatorial chemistry, special analytical tools, specialized pilot plants, etc.
  2. Income tax concessions (weighted tax deductibility): For both in-house and sponsored research programs.
  3. Soft loans: For financing approved R&D projects from the Government financial institutions / banks.
  4. Tax holidays: Deferrals, loans on earnings from R&D.
  5. Government funding: Government grants though available, tend to be small and typically targeted to government institutions or research bodies. There is very little government support for private sector R&D as on date.

All these schemes need to be simple and hassle free and the eligibility criteria must be stringent to prevent any possible misuse.

Patent infrastructure:

Overall Indian patent infrastructure needs to be strengthened, among others, in the following areas:

  • Enhancement of patent literacy both in legal and scientific communities, who must be taught how to read, write and file a probe.
  • Making available appropriate ‘Search Engines’ to Indian scientists to facilitate worldwide patent searches.
  • Creating world class Indian Patent Offices (IPOs) where the examination skills and resources will need considerable enhancement.
  • ‘Advisory Services’ on patents to Indian scientists to help filing patents in other countries could play an important role.

Creating R&D ecosystem:

  • Knowledge and learning need to be upgraded through the universities and specialist centers of learning within India.
  • Science and Technological achievements should be recognized and rewarded through financial grants and future funding should be linked to scientific achievements.
  • Indian scientists working abroad are now inclined to return to India or network with laboratories in India. This trend should be effectively leveraged.

Universities to play a critical role:

Most of Indian raw scientific talents go abroad to pursue higher studies.  International Schools of Science like Stanford or Rutgers should be encouraged to set up schools in India, just like Kellogg’s and Wharton who have set up Business Schools. It has, however, been reported that the Government of India is actively looking into this matter.

‘Open Innovation’ Model:

As the name suggest, ‘Open Innovation’ or the ‘Open Source Drug Discovery (OSDD)’ is an open source code model of discovering a New Chemical Entity (NCE) or a New Molecular Entity (NME). In this model all data generated related to the discovery research will be available in the open for collaborative inputs. In ‘Open Innovation’, the key component is the supportive pathway of its information network, which is driven by three key parameters of open development, open access and open source.

Council of Scientific and Industrial Research (CSIR) of India has adopted OSDD to discover more effective anti-tubercular medicines.

Insignificant R&D investment in Asia-Pacific Region:

Available data indicate that 85 percent of the medicines produced by the global pharmaceutical industry originate from North America, Europe, Japan and some from Latin America and the developed nations hold 97 percent of the total pharmaceutical patents worldwide.

MedTRACK reveals that just 15 percent of all new drug development is taking place in Asia-Pacific region, including China, despite the largest global growth potential of the region.

This situation is not expected to change significantly in the near future for obvious reasons. The head start that the western world and Japan enjoy in this space of the global pharmaceutical industry would continue to benefit those countries for some more time.

Some points to ponder:

  • It is essential to have balanced laws and policies, offering equitable advantage for innovation to all stakeholders, including patients.
  • Trade policy is another important ingredient, any imbalance of which can either reinforce or retard R&D efforts.
  • Empirical evidence across the globe has demonstrated that a well-balanced patent regime would encourage the inflow of technology, stimulate R&D, benefit both the national and the global pharmaceutical sectors and most importantly improve the healthcare system, in the long run.
  • The Government, academia, scientific fraternity and the pharmaceutical Industry need to get engaged in various relevant Public Private Partnership (PPP) arrangements for R&D to ensure wider access to newer and better medicines in the country, providing much needed stimulus to the public health interest of the nation.

Conclusion:

R&D initiatives, though very important for most of the industries, are the lifeblood for the pharmaceutical sector, across the globe, to meet the unmet needs of the patients. Thus, quite rightly, the pharmaceutical Industry is considered to be the ‘lifeline’ for any nation in the battle against diseases of all types.

While the common man expects newer and better medicines at affordable prices, the pharmaceutical industry has to battle with burgeoning R&D costs, high risks and increasingly long period of time to take a drug from the ‘mind to market’, mainly due to stringent regulatory requirements. There is an urgent need to strike a right balance between the two.

In this context, it is indeed a proud moment for India, when with the launch of its home grown new products, Synriam of Ranbaxy and Lipaglyn of Zydus Cadilla or Rotavac Vaccine of Bharat Biotech translate a common man’s dream of affordable new medicines into reality and set examples for others to emulate.

Thus, just within seven years from the beginning of the new product patent regime in India, stories like Synriam, Lipaglyn, Rotavac or the R&D pipeline of over 50 NCEs/NMEs prompt resurfacing the key unavoidable query yet again:

Has Indian pharma started catching-up with the process of new drug discovery, after decades of hibernation, to move up the industry ‘Value Chain’?

India, China Revoke Four Pharma Patents in A Fortnight: A Double Whammy for MNCs?

Revocation of four pharma patents by India and China within a fortnight has raised many eyebrows, yet again, across the globe. In this short period, India has revoked three patents and China one.

While this quick development is probably a double whammy for the Multinational Corporations (MNCs) operating in both the countries, a future trend could possibly emerge by analyzing and connecting the evolving dots.

On August 8, 2013, a judicial body, the Intellectual Property Apellate Board (IPAB) of India reportedly revoked two patents of Allergan Inc on Combigan and Ganfort, both are Fixed Dose Combination (FDC) drugs of known molecules, used in the treatment of specified eye conditions. Local pharmaceutical player Ajantha Pharma had challenged these patents granted earlier to Allergan Inc. by the Indian Patent Office (IPO), alleging that the patents were obtained on false representation, the compositions were obvious ones, mere admixture of two pharmaceutical substances and not inventions.

IPAB in its order, while revoking the patent, has also said:

  • “The revocation of the patent was sought on various grounds that the patent was obtained on a false suggestion or representation, that it is not an invention, that it is obvious and does not sufficiently disclose and that the Section 8 of the Patents Act, 1970 was violated.”
  • The “respondents (Allergan Inc) have incorrectly deciphered enhancement in therapeutic efficacy as reduction in interocular pressure comparable to serial application.”
  • “The respondent has not shown that it had complied with the Section 8 of Patents Act, 1970.”

Though Allergan claimed to have achieved enhanced efficacy with reduced side effects for these FDCs, the IPAB did not find the claims justifiable. Interestingly, Ajantha’s product reportedly is much less expensive too. As compared to Allergan’s Ganfort drops (3 ml) costing about Rs 580, Ajanta’s equivalent formulation costs just Rs 131.

The other pharma patent revocation of the fortnight:

On July 27, 2013, IPAB revoked yet another patent granted earlier to GlaxoSmithKline (GSK)’s Lapatinib ditosylate salt of its breast cancer drug Tykerb, while upholding the patent on the original API, Lapatinib. IPAB in its order has stated that the ditosylate salt version of Lapatinib is not patentable as per patentability criteria of the Indian Patents Act.

Experts believe, with these decisions, the Indian legal system has clearly demonstrated that despite intense anger, pressure and protests mainly from the United States and Europe, to dilute public health interest related safeguards enshrined in the current Indian patent regime, the rule of law still prevails in the country for IP disputes.

Tykerb decision of IPAB follows the landmark judgment of the Supreme Court of India clarifying patentability criteria for incremental innovations.

An interesting precedent set:

In case of Tykerb of GSK, unlike other occasions, for the first time one MNC has challenged the patent of another MNC in India, instead of domestic companies doing so. The German drug manufacturer, Fresenius Kabi, instead of criticizing Indian IP law like other MNCs, had challenged the British drug maker GSK’s patent on the patentability criteria as provided in the Indian Patent Law and obtained a favorable decision from the IPAB against one of their two patent challenges on Tykerb.

A different case, yet worth mentioning:

Earlier, in late 2012, Delhi High Court while recognizing the validity of Roche’s patent for Tarceva (erlotinib), ordered that Cipla’s generic equivalent of erlotinib has different molecular structures. Hence, Cipla has not infringed Roche’s patent.

The generic version of Cipla’s erlotinib is reportedly available at a price of Rs 1,600 against Roche’s price of Rs 4,800 for Tarceva. Though this is not a patent revocation, but an interesting case nevertheless.

Other patent revocations:

Besides the only Compulsory License (CL) issued, so far, by the IPO for Bayer’s Nexavar to Natco (Cost of a pack of 120 tablets of Natco generic is Rs.8,800 against Nexavar’s Rs. 280,000), such patent challenges are now taking place in India quite close on the heels of one another as follows:

Sutent (Pfizer): 

In this case, the patent for liver and kidney cancer drug of Pfizer – Sutent (Sunitinib), granted earlier by the IPO in 2007, was revoked by the IPAB in October 2012, after a post grant challenge by Cipla and Natco Pharma on the ground that the claimed ‘invention’ does not involve inventive steps.

However, on November 26, 2012 in a new twist to this case, the Supreme Court of India reportedly restored the patent for Sutent. Interestingly, at the same time the court removed the restraining order, which prevented Cipla from launching a copycat generic equivalent of Sunitinib.

The cost of 45 day’s treatment with Cipla generic is Rs. 50,000 against Rs. 196,000 of Sutent. (Source ET, April 7, 2013)

Pegasys (Roche):

Again, on November 2, 2012 the IPAB revoked the patent of Pegasys (Peginterferon alfa-2a) – the hepatitis C drug of the global pharmaceutical giant Roche. It is worth mentioning, Pegasys enjoys patent protection across the world.

Though Roche was granted a patent for Pegasys by IPO in 2006, this was subsequently contested by a post-grant challenge by the Indian pharma major – Wockhardt and the NGO Sankalp Rehabilitation Trust (SRT) on the ground that Pegasys is neither a ‘novel’ product nor did it demonstrate ‘inventiveness’ as required by the Patents Act of India.

It is worth noting, although the IPO had rejected the patent challenges by Wockhardt and SRT in 2009, the judicial body IPAB reversed IPO’s decision revoking the patent of Pegasys, costing Rs. 360,000 for a six month course of treatment for a patient.

Iressa (AstraZeneca):

On November 26, 2012, IPAB reportedly denied patent protection for AstraZeneca’s anti-cancer drug Iressa (Gefitinib) on the ground that the molecule lacked invention.

The report also states that AstraZeneca suffered its first setback on Gefitinib in June 2006, when the Indian generic company Natco Pharma opposed the initial patent application filed by the global major in a pre-grant opposition. Later on, another local company, GM Pharma, joined Natco in November 2006.

After accepting the pre-grant opposition by the two Indian companies, IPO in March 2007 rejected the patent application for Iressa Gefitinib citing ‘known prior use’ of the drug. AstraZeneca contested the order through a review petition, which was dismissed in May 2011.

Anti-asthma FDC aerosol suspension (Merck & Co):

Similar to Allergan case, on December 11, 2012 Indian Patent Office (IPO) reportedly revoked a patent granted to an anti-asthma FDC drug of Merck & Co on the ground of lack of invention, after the domestic pharma major Cipla Ltd challenged an earlier granted patent of this FDC drug.

This aerosol suspension combines three molecules: mometasone furoate, formoterol and heptaflouropropane.

A similar asthma treatment, Dulera, reportedly lost its Indian patent held by Novartis AG in 2010.

Patentability for ‘Incremental Innovations’ in India:

Patentability criteria for any ‘incremental innovation’ has been defined in the Section 3(d) of the Indian statute as follows:

“The mere discovery of a new form of a known substance which does not result in the enhancement of the known efficacy of that substance or the mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.”

“Explanation: For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance, unless they differ significantly in properties with regard to efficacy.”

Indian Patents Act prevails: 

As is well known, way back in 2006, IPO refused to grant patent to the cancer drug Glivec of Novartis on the ground that the molecule is a mere modification of an existing substance known as Imatinib.

In that case, on April 1, 2013 the Supreme Court of India upheld the validity of Section 3(d), where the rules of the game for patentability of incremental pharmaceutical innovations, as captured in the Indian Patents Act 2005, were cast in stone.

Court did not disallow all incremental innovations:

Point 191 in page number 95 of the Glivec judgment very clearly states as follows:

“191. We have held that the subject product, the beta crystalline form of Imatinib Mesylate, does not qualify the test of Section 3(d) of the Act but that is not to say that Section 3(d) bars patent protection for all incremental inventions of chemical and pharmaceutical substances. It will be a grave mistake to read this judgment to mean that section 3(d) was amended with the intent to undo the fundamental change brought in the patent regime by deletion of section 5 from the Parent Act. That is not said in this judgment.”

Thus, it should not be highlighted unfairly by concerned constituents that all ‘incremental innovations’ are not patentable in India. The above judgment just says that Glivec is not patentable as per Section 3(d) of Indian Patents Act based on the data provided and the arguments of Novartis.

Only 3% of patents are challenged:

Quoting a study, a recent media report highlighted that only 3% of the patent applications filed in India since 2006 were challenged. The study concluded, “This demonstrates that given the various resource constraints faced by the Indian patent office, one can never really be sure of the patent quality unless the patent is challenged.”

Rejection by IPO under Section 3d is minimum – is that a key issue?

Another study done by Columbia University reportedly found that out of 214 patents filed in India last year, only 3 patents were rejected by IPO exclusively for failing to prove better efficacy, as required under Section 3d. Turning this finding on its head, would it be reasonable to ponder:

Could this be a key issue for so many patents failing to pass the acid test of judicial scrutiny when challenged?

Government has no role to play in IP disputes:

The proponents of ‘no change required in the Section 3(d)’ argue, patent challenge is a legal process all over the world, where the Government has hardly any role to play in resolving these disputes. The law should be allowed to take its own course for all disputes related to the Patents Act of the country, including Section 3(d).

They also opine that India must be allowed to follow the law of justice without casting aspersions on the knowledge and biases of the Indian judiciary by the vested interests.

That said, there is certainly an urgent need to add speed to this legal process by setting up ‘Fast-track Courts’ for resolving all Intellectual Property (IP) related disputes in a time bound manner.

Pharma patents granted in India:

As reported in the media, pharma MNCs have been granted over 1,000 patents since 2005. Moreover out of 4,036 patents granted in the past six years, 1,130 have been awarded to MNCs, like:

  • AstraZeneca 180 patents
  • Roche with 166 patents
  • Sanofi with 159 patents
  • Novartis with 147 patents

It is therefore understandable, as pharma MNCs have secured more number of pharma patents they are facing larger number of litigations at this point of time.

China and Brazil revoke patents:

Last week, just about a year after China introduced the country’s amended patent law, its State Intellectual Property Office (SIPO) has reportedly revoked the patent on HIV/AIDS and hepatitis B drug – Viread (tenofovir disoproxil fumarate) of Gilead Science Inc. Aurisco, the largest manufacturer of active pharmaceutical ingredients in China, challenged this patent. The ground of patent revocation was that the drug lacked novelty and was not entitled to protection.

In 2008 Brazil also declared the patent of tenofovir invalid. It is worth mentioning that tenofovir of Gilead is the third-best-selling drug of the company, clocking sales of US$ 849 million in 2012.

South Africa mulls new law to stop ‘Evergreening’:

Recently, the Department of Trade and Industry of South Africa has reportedly submitted to the South African Cabinet a draft Intellectual Property Policy with far-reaching changes to the country’s Intellectual Property Rights (IPR) for medicines in order to increase access to cheaper drugs by making it harder for companies to obtain and extend patents.

The draft includes a proposal to introduce a patent examination office to stop pharmaceutical companies from “evergreening” where companies take out new patents based on minor changes or new uses. 

Currently, South Africa uses a depository system, in which patent applications are granted without extensive scrutiny. Experts believe, “this system allows companies to file multiple patents on the same medicine and extend the life of their monopoly, keeping prices artificially high.”

Innovators Angry:

In this context, the following report recently captured the anger of the innovator companies and stated that the US drug giants are once again pushing for stronger patent protection in India:

“A coalition of U.S. lawmakers and business groups outlined concerns about Indian policies as a threat to American exports, jobs and innovation in a letter to President Barack Obama on June 18. Among the business groups were the Pharmaceutical Research and Manufacturers of America and the Biotechnology Industry Association. On June 14, the top Democrat and Republican on the Senate Finance Committee urged that Kerry raise trade concerns on his visit.”

Quoting US Chamber of Commerce’s Global Intellectual Property Center another report highlighted, “Recent policy and judicial decisions that invalidate intellectual property rights, which have been increasing in India, cast a daunting shadow over its otherwise promising business climate. From the revocation of patents to the staggering rates of piracy, India stands alone as an international outlier in IP policies. This trend is bad for investment, innovation and international trade.”

Does it benefit patients? 

In the paper titled ‘TRIPS, Pharmaceutical Patents and Access to Essential Medicines: Seattle, Doha and Beyond’, published in ‘Chicago Journal for International Law, Vol. 3(1), Spring 2002’, the author argues, though the reasons for the lack of access to essential medicines are manifold, there are many instances where high prices of drugs deny access to needed treatments for many patients. Prohibitive drug prices, in those cases, were the outcome of monopoly due to strong intellectual property protection.

The author adds, “The attempts of Governments in developing countries to bring down the prices of patented medicines have come under heavy pressure from industrialized countries and the multinational pharmaceutical industry”.

While the ‘Trade-Related Aspects of Intellectual Property Rights Agreement (TRIPS)’ of the World Trade Organization (WTO) sets out minimum standards for the patent protection for pharmaceuticals, it also offers adequate safeguards against negative impact of patent protection or its abuse in terms of extraordinary and unjustifiable drug pricing. The levels of these safeguards vary from country to country based on the socioeconomic and political requirements of a nation, as in India.

Patentability for ‘genuine innovations’:

A report on ‘Patentability of the incremental innovation’ indicates that the policy makers keeping the following points in mind formulated the Indian Patents Act 2005:

  • The strict standards of patentability as envisaged by TRIPS pose a challenge to India’s pharmaceutical industry, whose success depended on the ability to produce generic drugs at much cheaper prices than their patented equivalents.
  • A stringent patent system would severely curtail access to expensive life saving drugs to a large number of populations in India causing immense hardships to them.
  • Grant of a product patents should be restricted only to “genuine innovations” and those “incremental innovations” on existing medicines, which will be able to demonstrate significantly increased efficacy over the original drug.

Conclusion:

study by the ‘Indian Pharmaceutical Alliance (IPA)’ indicates that 86 pharmaceutical patents granted by the IPO post 2005 are not breakthrough inventions but only minor variations of existing pharmaceutical products and demanded re-examination of them.

Since, most of the above patents have not been challenged, as yet, the quality of these patents cannot be ascertained beyond any reasonable doubt, as we discuss today.

If the apprehension, as expressed above in the IPA study has any merit, right answers to the following questions, I reckon, would help charting out the future direction for the IP ecosystem of India:

  • Is there a theoretical possibility of revocation of all these 86 already granted product patents, if and when challenged in a court of law?
  • Is the current Patents Act of India pragmatic?
  • Does it reasonably benefit both the innovators and the Indian patients,  signifying a paradigm shift in the global IPR scenario?
  • Will it inspire other countries also to emulate similar IP system in the years ahead?
  • Will it then invite more intense ire of the global pharma innovator companies creating increasing  pressure on the Indian Government to amend the current Patents Act?
  • Being under continuous public scrutiny, would it be feasible for any Indian Government, now or in future, in the near or medium term, to amend the Indian Patents Act due to any amount of outside pressure?
  • And finally, is the Act then irreversible, at least, for quite some time from now?

Is Fraud or Negligence in Drug Quality Standards Not a Fraud on Patients?

As we know, a substance is called a drug when it has scientifically proven and well documented efficacy and safety profile to reduce both mortality and morbidity of patients. Any fraud or negligence in the drug quality standards, for whatever may be the reasons or wherever these take place, is a fraud on patients and should warrant zero tolerance.

A perception survey on drug quality:

According to a poll released in 2010 by the ‘Pew Charitable Trusts’s Prescription Project’ of the United States:

  • More than three out of four voters are confident that prescription drugs made in the USA are free from contamination
  • While less than one in 10 feel confident about medications made in India or China.
  • 54 percent of Americans distrusted Indian drugs and 70 percent distrusted Chinese drugs.
  • “When you buy a shirt, it will say right on the label where it was made, but when you get a pharmaceutical, you don’t know.”

Despite all these, the survey points out that in 2007, 68 percent of the ingredients of all drugs sold worldwide came from India or China, as compared to 49 percent in 2004.

Experts comment that USFDA does not have either people or resources required to monitor manufacturing in the geographically widespread locations, as these are today.

Recent spate of charges against Indian pharmaceutical companies – a vindication?

Recent spate of charges against some top ranked Indian companies, will further dent the image of India not just in the United States or Europe, but also as a pharmacy of high quality yet low cost generic drugs for the developing countries of the world.

In May 2013, well known India-based pharma major Ranbaxy reported to have pleaded guilty to criminal charges of manufacturing and distributing some adulterated medicines, produced at its Paonta Sahib and Dewas, facilities and agreed to US$ 500-millon settlement. Can this be considered as a vindication of the above perception on the quality of ‘made in India’ drugs?

The view of WHO:

Interestingly the World Health Organisation (WHO) even after the above USFDA indictment has commented that at present it has no evidence that Ranbaxy manufactured medicines that are currently prequalified by WHO are of unacceptable quality.

Indian drug regulator initiates action:

It is good to know that the Drugs Controller General of India (DCGI) and the Ministry of Health will reportedly decide the way forward in this matter on completion of a fact-finding study initiated by the Central Drugs Standards Control Organization (CDSCO) on the subject.

Other incidents in India:

Following are examples of other reported serious regulatory violations involving the domestic pharmaceutical companies:

Source: The Economic Times (May 22, 2013), Financial Express (May 25, 2013)

Though some other countries also have faced bans from exporting products, it cannot be taken, I reckon, as any consolation by anyone.

A Mumbai Hospital demonstrated the mood of zero tolerance:

The above expression of good intent should not just remain as a ‘lip service’. Indian drug regulator is expected to take a leaf out of all these allegations and initiate appropriate audit as required. Otherwise, exhibiting zero tolerance, like Jaslok Hospital of Mumbai, many other institutions will ask their doctors not to prescribe products of these companies to protect patients’ interest. More hospitals reportedly are mulling similar action against Ranbaxy.

IMA expresses apprehension:

Even ‘The Indian Medical Association (IMA)’ has reportedly asked the DCGI to investigate quality of medicines manufactured by Ranbaxy.

It happens in the ‘heartland’ too just as in the ‘hinterland’:

Contrary to the above poll released in 2010 by the ‘Pew Charitable Trusts’s Prescription Project’, pointing accusing fingers, in this respect, exclusively to India and China, may not be just fair. Incidents of such regulatory violations are not just restricted to Indian pharmaceutical companies either. Unfortunately, these happen with the global majors too.

None of these should be condoned in any way by anyone and attract as much global publicity, public wrath and zero tolerance, as all these would possibly deserve.

Further, in December 1998 the US FDA reportedly had stopped shipments of Abbott Laboratories’ clot-busting drug Abbokinase till the company had resolved undisclosed manufacturing problems at its plant. Abbott subsequently resolved this to the satisfaction of the drug regulator.

Even end May 2011, the USFDA reportedly raised concerns about contamination of drugs of the American pharmaceutical major – Hospira, at its Indian manufacturing facility.This issue was highlighted as the latest in a string of manufacturing and quality problems dogging the company since 2010.

American lawmakers demand thorough review of USFDA oversight procedures:

Pressure has reportedly started mounting in the United States for a thorough review into the effectiveness of oversight procedures for all bulk drugs and formulations manufactured in foreign facilities.

Simultaneously, there is also a specific demand for an in-depth review of all actions of the US regulator for so many years, which allowed Ranbaxy’s ‘massive fraud to remain unchecked’.

Beyond regulatory oversight, need robust internal system driven model as a fire-wall:

To address such issues only drug regulators interventions may not be just enough, maintaining total integrity of ‘Supply Chain’ of an organization proactively in a well structured, fool-proof and a system-driven way, will continue to play the most critical role. This will help creating ‘fire-wall’, which will be difficult to breach.

The scope of Supply Chain:

The scope of ‘Supply Chain’, which is comprised of the entire network of entities from vendors who supply raw and packaging materials, manufacturers who convert these materials into medicines, together with warehouses, distributors, retailers and healthcare centers who will reach these medicines ultimately to patients exactly the way these will deserve.

Thus, just not in the manufacturing process, any breach of security at any place of the supply chain can cause serious problems to patients. 

Accordingly, pharmaceutical companies need to adequately invest along with appropriate staff training programs to ensure that the Supply Chain Integrity is maintained, always.

Supply Chain Security (SCS) is critical:

SCS, therefore, deserves to be of prime importance for the pharmaceutical companies across the globe. Recent high profile SCS related cases, as mentioned above, have exposed the vulnerability in addressing this global menace effectively.

All pharmaceutical players should realize that not just ‘show-off’, an effective integrated approach is of paramount importance to eliminate this crime syndicate, which is taking lives of millions of patients the world over.

Mixing-up counterfeit drugs with this menace may not be prudent:

Shouting for counterfeit drugs involving mainly intellectual property related issues, may be  important, but will in no way help resolving self-created menaces arising out of breach of supply chain integrity endangering million of lives, in another way.

Though an expensive process, can’t be compromised:

It is worth repeating, securing pharmaceutical supply chain on a continuous basis is of critical importance for all the pharmaceutical players across the globe. However, the process will no doubt be expensive for any company.

Like other industries, in the pharmaceutical sector, as well, cost effective procurement is critical, which entices many pharmaceutical players, especially, in the generic industry not to go for such expensive process just to maintain the SCS.

A serious SCS related tragedy:

I would like to reinforce my argument on the importance of SCS with the following example of the ‘Heparin tragedy’ where the supply chain integrity was seriously violated with ‘ingeneuity’.

In the beginning of 2008, there were media reports on serious adverse drug events, some even fatal, with Heparin, a highly sulfated glycosaminoglycan of Baxter International. Heparin is widely used as an injectable anticoagulant. Baxter voluntarily recalled almost all their Heparin products in the U.S. Around 80 people died from contaminated Heparin products in the U.S. The US FDA reported that such contaminated Heparin was detected from at least 12 other countries.

A joint investigation conducted by Baxter and the US FDA ascertained that the Heparin used in batches associated with the serious adverse drug events was contaminated with Over Sulfated Chondroitin Sulfate (OSCS). It was reported that Heparin Scientific Protein Laboratories, Changzhou, China supplied Heparin to Baxter.

The cost of OSCS is just a fraction of the ingredient used in Heparin. Being driven by the criminal profiteering motive the manufacturers in Changzhou, China had reportedly used OSCS for highly sulfated glycosaminoglycan, as the former could not be detected by the pharmacopeia test in use, until 2008. This is because OSCS mimics Heparin in the pharmacopeia test. Post this criminal event, at present, all over the world more specific pharmacopeia test methods have been adopted for Heparin.

Stakeholders need to be extremely vigilant:

Considering all these, pharmaceutical players and the drug regulators from across the world should put proper ‘fool proof’ systems in place to eliminate the growing menace of criminal adulteration of APIs, drug intermediates, excipients entering in the supply chain together with preventing any breach in their logistics support systems.

Apprehension against generic drugs as a class:

Taking advantage of the situation, one can possibly say, as some vested interests have already started propagating that generic equivalents of the branded drugs are really not quite the same in quality.

However, the point that cannot be ignored is the comment of a senior USFDA, who was quoted in the same article saying, “I have heard it enough times from enough people to believe that there are a few products that aren’t meeting quality standards.

Generic drug manufacturers should make serious note of such comments and act accordingly to allay prevailing lurking fear on the use of generic medicines, in general, though small in number.

Conclusion:

Following the recent series of incidents including that of Ranbaxy, the image of India as a low cost generic drugs manufacturer of high quality could get adversely impacted. Although there are enough instances that such things happen in the developed world, as well, including the United States.

Moreover, in the backdrop of high decibel quality concerns raised by USFDA, the level of apprehension regarding effectiveness of generic drugs made in India may increase significantly, unless some tangible, well thought out and highly publicized remedial measures are taken forthwith.

The decision of Jaslok Hospital, Mumbai advising their doctors for not using Ranbaxy products to patients on the same ground, will further strengthen the public apprehension.

Whatever may be the reason, as long as any company is in the business of manufacturing medicines, there should be demonstrable zero tolerance on any compromise, fraud or negligence in the drug quality standards. Any fraud and negligence in drug quality, I reckon, is virtually a fraud against humanity.

That said, changing mindset towards a strong corporate governance by walking the talk, all pharmaceutical companies must guarantee safe and high quality medicines to the society, come what may.

This, I believe, could be achieved by putting in place a robust SCS system and ensuring that this is not compromised in any way… anywhere…ever… for patients’ sakeboth globally and locally.

Does the Landmark Glivec Judgment Discourage Innovation in India?

No, I do not think so. The 112 pages well articulated judgment of the Supreme Court of India delivered on April 1, 2013, does not even remotely discourage innovation in India, including much talked about ‘incremental innovation’. This landmark judgment reconfirms the rules of the game for pharmaceutical innovation, as captured in the Indian Patents Act 2005.

When one reads the judgment, point 191 in page number 95 very clearly states as follows:

“191. We have held that the subject product, the beta crystalline form of Imatinib Mesylate, does not qualify the test of Section 3(d) of the Act but that is not to say that Section 3(d) bars patent protection for all incremental inventions of chemical and pharmaceutical substances. It will be a grave mistake to read this judgment to mean that section 3(d) was amended with the intent to undo the fundamental change brought in the patent regime by deletion of section 5 from the Parent Act. That is not said in this judgment.”

Thus all ‘incremental innovations’, which some people always paint with a general broad brush of ‘evergreening’, should no longer be a taboo in India. The judgment just says that Glivec is not patentable as per Section 3(d) of Indian Patents Act based on the data provided and arguments of Novartis.

To me, the judgment does also not signal that no more Glivec like case will come to the Supreme Court in future. It vindicated inclusion of Section 3(d) in the amended Indian Patents Act 2005.

It is interesting to note that honorable Supreme Court itself used the terminology of ‘incremental innovation’ for such cases.

That said, I find it extremely complex to imagine what would have happened, if the judgment had gone the opposite way.

A critical point to ponder:

The judgment will also mean that all those products, having valid product patents abroad, if fail to meet the requirements of Section 3(d), will not be patentable in India, enabling introduction of their generic equivalents much sooner in the country and at the same time causing a nightmarish situation for their innovators.

However, this again, in no way, is an outcome of this judgement or a new development, as stated above. It is just vindication of the intent behind inclusion of Section 3(d) in the amended Indian Patents Act, when it was enacted by the Parliament of India in 2005.

Patentability of ‘Incremental Innovations’ in India:

Patentability criteria for any ‘incremental innovations’ has been defined in the Section 3(d) of the Indian statute as follows:

“The mere discovery of a new form of a known substance which does not result in the enhancement of the known efficacy of that substance or the mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant.

Explanation: For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance, unless they differ significantly in properties with regard to efficacy.

Supreme Court interpretation of the term “Efficacy” in Section 3(d): 

The Honorable Supreme Court in page 90 of its above order under point 180 stated that in case of medicines, efficacy can only be “therapeutic efficacy”, which must be judged strictly and narrowly. The interpretation goes as follows:

180. “What is “efficacy”? Efficacy means ‘the ability to produce a desired or intended result’. Hence, the test of efficacy in the context of section 3(d) would be different, depending upon the result the product under consideration is desired or intended to produce. In other words, the test of efficacy would depend upon the function, utility or the purpose of the product under consideration. Therefore, in the case of a medicine that claims to cure a disease, the test of efficacy can only be “therapeutic efficacy”.

The Honorable Court under the same point 180 further elaborated:

“With regard to the genesis of section 3(d), and more particularly the circumstances in which section 3(d) was amended to make it even more constrictive than before, we have no doubt that the “therapeutic efficacy” of a medicine must be judged strictly and narrowly…Further, the explanation requires the derivative to ‘differ significantly in properties with regard to efficacy’. What is evident, therefore, is that not all advantageous or beneficial properties are relevant, but only such properties that directly relate to efficacy, which in case of medicine, as seen above, is its therapeutic efficacy.” 

Based on this interpretation of Section 3(d), the Honorable Supreme Court of India ordered that Glivec does not fulfill the required criteria of the statute.

The rationale behind Section 3(d):

A report on ‘Patentability of the incremental innovation’ indicates that the policy makers keeping the following points in mind formulated the Indian Patents Act 2005:

  • The strict standards of patentability as envisaged by TRIPS pose a challenge to India’s pharmaceutical industry, whose success depended on the ability to produce generic drugs at much cheaper prices than their patented equivalents.
  • A stringent patent system would severely curtail access to expensive life saving drugs to a large number of populations in India.
  • Grant of a product patents should be restricted only to “genuine innovations” and those “incremental innovations” on existing medicines, which will be able to demonstrate significantly increased efficacy over the original drug.

IPA challenges: 86 pharmaceutical patents granted by IPO fall under Section 3(d):

study by the ‘Indian Pharmaceutical Alliance (IPA)’ indicates that 86 pharmaceutical patents granted by the IPO post 2005 are not breakthrough inventions but only minor variations of existing pharmaceutical products and demanded re-examination of them.

Possible implications to IPA challenge:

If the argument, as expressed above in the IPA study, is true by any stretch of imagination, in that case, there exists a theoretical possibility of at least 86 already granted product patents to get revoked. This will invite again another nightmarish situation for innovators.

Examples of revocation of patents in India:

On November 26, 2012, the Intellectual Property Appellate Board (IPAB) reportedly denied patent protection for AstraZeneca’s anti-cancer drug Gefitinib on the ground that the molecule lacked invention.

The report also states that AstraZeneca suffered its first setback on Gefitinib in June 2006, when the Indian generic company Natco Pharma opposed the initial patent application filed by the global major in a pre-grant opposition. Later on, another local company, GM Pharma, joined Natco in November 2006.

After accepting the pre-grant opposition by the two Indian companies, the Indian Patent office (IPO) in March 2007 rejected the patent application for Gefitinib citing ‘known prior use’ of the drug. AstraZeneca contested the order through a review petition, which was dismissed in May 2011.

Prior to this, on November 2, 2012 the IPAB revoked the patent of Pegasys (Peginterferon alfa-2a) – the hepatitis C drug of the global pharmaceutical giant Roche.

Though Roche was granted a patent for Pegasys by the Indian Patent Office (IPO) in 2006, this was subsequently contested by a post-grant challenge by the large Indian pharma player – Wockhardt and the NGO Sankalp Rehabilitation Trust (SRT) on the ground that Pegasys is neither a “novel” product nor did it demonstrate ‘inventiveness’, as required by Section 3(d) of Patents Act of India 2005.

It is worth noting, although the IPO had rejected the patent challenges by Wockhardt and SRT in 2009, IPAB reversed IPO’s decision revoking the patent of Pegasys.

Similarly the patent for liver and kidney cancer drug of Pfizer – Sutent (Sunitinib) granted by IPO in 2007, was revoked by the IPAB in October, 2012 after a post grant challenge by Cipla and Natco Pharma on the ground that the claimed ‘invention’ does not involve inventive steps.

Patent challenges under section 3(d) may come up even more frequently in future:

Some observers in this field have expressed, although ‘public health interest’ is the primary objective for having Section 3(d) in the Indian Patents Act 2005, many generic companies, both local and global, have already started exploiting this provision as a part of their ‘business strategy’ to improve business performance in India, especially when an  injunction is usually not being granted by the honorable Courts for such cases on public health interest ground.

Thus, as stated above, there is likely to be many more cases like, Glivec coming before the Supreme Court in the years ahead.

Another related development of the last week:

It has been reported that American pharma major MSD has last week filed a suit in the Delhi High Court against Indian pharma major – Glenmark for alleged patent violation of its leading anti-diabetic drugs Januvia and Janumet. In this case also no interim injunction has reportedly been granted to MSD by the Honorable Delhi High Court.

Glenmark has stated through a media report, “It is a responsible company and has launched the products after due diligence and research.” The company has also announced that their version of the molecule named Zita and Zita Met will be available to patients at a 20 percent discount to MSD’s price.

Hence, once again, the Indian court to decide, the balance of justice would now point to which direction.

Government has no role to play – patent challenge is a legal process across the world:

The proponents of ‘no change required in the Section 3(d)’ argue, ‘Patent Challenge’ is a legal process all over the world, the Government has hardly got any role to play in settling such disputes. The law should be allowed to take its own course for all disputes related to the Patents Act of the country, including Section 3(d).

They also opine that India must be allowed to follow the law of justice without casting aspersions on the knowledge and biases of the Indian judiciary for vested interests.

That said, there is certainly an urgent need to add speed to this legal process by setting up ‘Fast-track Courts’ for resolving all Intellectual Property (IP) related disputes in a time bound manner.

Arguments against Section 3(d):

Opposition to the Section 3(d) counter-argues by saying, this is a critical period for India to help fostering an appropriate ecosystem for innovation in the country. This group emphasizes, “Providing the right incentives for incremental pharmaceutical innovation can move India forward on this path and encourage the development of drug products that meet the needs of Indian patients. Reforming Section 3(d) to encourage and protect incremental pharmaceutical innovation would create such incentives and help India become a true powerhouse of innovation.”

Another group says that the main reason in favor of Section 3(d) being the provision will prevent grant of frivolous patents, the ultimate fallout of which will result in limited access to these drugs due to high price, is rather irrelevant today. This, they point out, is mainly because the Government is now actively mulling a structured mechanism of price negotiation for all patented drugs to improve their access to patients in India.

Importance of ‘Incremental Innovation’ in India:

Incremental innovations are indeed very important for the country and have been benefiting the patients immensely over decades, across the world.

A report titled, “The Value Of Incremental Pharmaceutical Innovation” highlighted as follows:

  • As per the National Knowledge Commission, while 37.3% of Indian companies introduced breakthrough innovations in recent years, no fewer than 76.4% introduced incremental innovations.
  • 60 percent of the drugs on the World health Organization’s essential Drug list reflect incremental improvements over older drugs.

The report indicates some of the benefits of ‘Incremental Pharmaceutical Innovation’ for India as follows:

  1. Improved quality of drug products, including products that are better suited to India’s climate.
  2. Development of treatments for diseases that are prevalent in India for which new drug discovery is currently limited or otherwise inadequate.
  3. Increasing likelihood that for every therapeutic class, there is a treatment to which an Indian patient will respond.
  4. Development of the R&D capacity and expertise
 of Indian pharmaceutical companies.
  5. Reduction of healthcare and other social costs in India through improved drug quality and selection.
  6. Increased access to medicine as a result of price competition.

The study concluded by saying that Section 3(d) potentially precludes the patenting of hundreds of incremental pharmaceutical innovations that Indian companies are attempting to patent and commercialize outside India.

There are umpteen numbers of examples that can ably demonstrate, ‘incremental innovation’ of the pharmaceutical innovators help significantly improving the efficacy and safety of existing drugs. All such innovations should in no way be considered “frivolous” as they have very substantial and positive impact in improving conditions of the ailing patients.

Be that as it may, the Supreme Court judgment has categorically mentioned that all ‘Incremental innovations’ should conform to the requirement of the Section 3(d) of the statute.

West should learn from India’s high patent standards”

An article appeared just yesterday written by a well-regarded Indian economist recommended, “West should learn from India’s high patent standards”. It observed that    over-liberal patent system of the West is now broken and it should learn from India’s much tougher patent system.

Patent monopolies needs to be given only for genuine innovations, as defined in the Indian Patents Act 2005, where the public benefits clearly exceed the monopoly cost.

The author concluded by saying, “This means setting a high bar for innovation. High standards are desirable for patents, as for everything else.”

View of the Glivec inventor: 

In another interview titled, “If you erode patents, where will innovations come from?” Dr Brian Druker, whose work resulted in the development of Glivec, re-emphasizing the need for R&D by the pharmaceutical industry, commented,  “I’m going to stay away from the legal judgment … but as a physician, I do recognize that the advances will come from new products, not modifications.

Are discordant voices out of step with time?

The interpretation of the Section 3(d) of the statute by the Honorable Supreme Court of India is the last word for all, despite a few voices of discord from within and mostly outside India. These voices, many would reckon, could well be out of step with time, especially in relatively fast growing, modern, independent, thinking and assertive young  India.

Conclusion:

In my view, nothing materially has changed on the ground before and after the Supreme Court judgment on the Glivec case so far as the Indian Patents Act is concerned and also in its interpretation.

While encouraging all types of innovations, including incremental ones and protecting them with an effective IPR regime are very important for any country. No nation can afford to just wish away various socioeconomic expectations, demands and requirements not just of the poor, but also of the growing middle class intelligentsia, as gradually getting unfolded in many parts of the globe.

Available indicators do point out that the civil society would continue to expect in return, just, fair, responsible and reasonably affordable prices for the innovative medicines, based on the overall socioeconomic status of the local population.

This critical balancing factor is essential not only for the progress of the pharmaceutical industry, but also to alleviate sufferings of the ailing population of the country, effectively.

For arguments sake, in an ideal scenario, if the Central and State Governments in India decide to buy such drugs to supply to all patients free of cost, just like any ‘welfare state’, will even the Government be able to afford these prices and fund such schemes in India?

It is, therefore, now widely expected that innovator pharmaceutical companies, which play a pivotal role in keeping population of any nation healthy and disease free to the extent possible, should also proactively find out ways to help resolving this critical issue in India, working closely with the Government of 1.2 billion Indians, including other concerned stakeholders.

In that context, the landmark Supreme Court judgment on the Glivec case has vindicated the need of striking a right balance between encouraging and protecting innovation, including incremental ones and the public health interest of India.

Takes ‘Two to Tango’: Encashing Opportunities with Biologic drugs in India

Despite current ‘Patent Cliff’ ongoing research on biologics is now at the forefront of the Global Pharmaceutical Industry.  The bottom-line impact of a successful new biologic molecule to treat intractable ailments like, cancer, blood disorders, Parkinson’s, Myasthenia Gravis, Multiple Sclerosis, Alzheimer’s diseases, will be huge.

Currently, faster growth of this segment as compared to conventional small molecules is primarily driven by novel technologies and highly targeted approaches, the final outcome of which is being more widely accepted by both physicians and patients.

Lesser generic competition makes it more attractive:

After patent expiry, innovators’ small molecule brands become extremely vulnerable to cut throat generic competition with as much as 90% price erosion.This is mainly because  these small molecules are relatively easy to replicate by many generic manufacturers and the process of getting their regulatory approval is also not as stringent as biosimilar drugs in most of the markets of the world.

On the other hand biologic drugs involve difficult, complex and expensive processes for development. Such resource intensive scientific expertise together with stringent regulatory requirements for obtaining marketing approval, especially in the developed markets of the world like, EU and USA, help creating a significant market entry barrier for many players. That is why even after patent expiry, biologics enjoy significant brand protection from generic competition for quite some time, in many cases.

It is for this reason brands like the following ones are expected to go relatively strong even for some more time, without any significant competition from biosimilar drugs in many of the major markets of the world:

Brand Company Launch date
Rituxan Roche/Biogen idec 1997
Herceptin Roche 1998
Remicade Centocor/J&J 1998
Enbrel Amgen/Pfizer 1998

Global Market:

In 2011 the turnover of Biologic drugs increased to over US$ 175 billion in the total market of US$ 847 billion. The sale of Biosimilar drugs outside USA exceeded US$ 1 billion.

Six biologic drugs featured in the top 10 best selling global brands in 2012 with Humira of AbbVie emerging as the highest-selling biologics during the year.  Roche remained the top company by sales for biologics with anticancer and monoclonal antibodies.

According to IMS Health, by 2015, sales of biosimilars are expected to reach between US$ 1.9 – 2.6 billion, an increase from US$ 378 million for the year to the first half of 2011.

Attractiveness:

The answer to the key question of why do so many companies want to enter into the biotech space of the business, in summary, could lie in the following:

  • Truly innovative small molecule discovery is becoming more and more challenging and expensive with the low hanging fruits already being plucked.
  • More predictable therapeutic activity of biologics with better safety profile.
  • Higher percentage of biologics have turned into blockbuster drugs in the recent past.
  • Market entry barrier for biosimilar drugs, after patent expiry of the original molecule, is much tougher than small molecule generics.
  • A diverse portfolio of both small and large molecules will reduce future business risks.

A 2012 report by PwC titled ‘From Vision to Decision: Pharma 2020’ states that “the next few years may look bleak for pharma, but we’re convinced that the following decade will bring a golden era of renewed productivity and prosperity.”

The document also points out that the global pharmaceutical industry is now focusing its R&D initiatives on biologics for the treatment of cancer and rare diseases. Nearly 30 percent of the 7,891 molecules currently in clinical testing cover cancer and autoimmune conditions.

Another emerging opportunity:

As stated above, unlike commonly used ‘small molecule’ drugs, ‘large molecule’ biologics are developed from living cells using very complex processes.

It is virtually impossible to replicate these protein substances, unlike the ‘small molecule’ drugs. One can at best develop a biologically similar molecule with the application of high degree of biotechnological expertise. These drugs are known as ‘Biosimilar Drugs’ and usually cost much less than the original ones.

Biosimilar drugs market is currently fast evolving across the world with varying degree of pace and stages of developments. The U.S currently holds the leadership status in the production of biologics, with around 45 percent of the total share. India’s share, now being at 7 percent is continuously increasing.

Future business potential with cost arbitrage of India:

In 2013, products like, Avonex of Biogen Idec, Humalog of Eli Lilly, Rebif of Merck KgaA, Nupugen of Amgen will go off-patent, paving the way of entry for lower priced biosimilar drugs. The sum total of revenue from all such drugs comes to over U.S$ 15 billion.

The report from the ‘Business Wire’ highlights that, ‘the manufacture and development of a biosimilar molecule requires an investment of about US$ 10 to 20 million in India, as compared to US$ 50 to 100 million in developed countries’, vindicates the emergence of another lucrative business opportunity for India for such drugs with significant cost arbitrage.

Government support in India:

In India, the government seems to have recognized that research on biotechnology has a vast commercial potential for products in human health, including biosimilars, diagnostics and immunobiologicals, among many others.

To give a fillip to the Biotech Industry in India the National Biotechnology Board was set up by the Government under the Ministry of Science and Technology way back in 1982. The Department of Biotechnology (DBT) came into existence in 1986. The DBT currently spends around US$ 300 million annually to develop biotech resources in the country and has been reportedly making reasonably good progress.

The DBT together with the Drug Controller General of India (DCGI) has now prepared ‘Regulatory Guidelines for Biosimilar Drugs’ in conformance to international quality and patient safety standards.

Currently, a number of both financial and non-financial incentives have been announced by the Central and the State Governments to encourage growth of the biotech industry in India, which include tax incentives, exemption from VAT and other fees, grants for biotech start-ups, financial assistance with patents, subsidies on investment from land to utilities and infrastructural support with the development of ten biotech parks through ‘Biotechnology Parks Society of India’.

A commendable DBT initiative:

Towards this direction, the Department of Biotechnology (DBT) of the Government of India has taken a commendable step to encourage the small and medium scale business outfits by setting-up ‘The Small Business Innovation Research Initiative (SBIRI)’. This scheme has been launched to boost ‘Public-Private-Partnership (PPP)’ projects in the country.

SBIRI supports ‘the high-risk pre-proof-of-concept research’ and ‘late stage development’ in small and medium size companies to get them involved in the development of biologics.

Some examples:

Examples of some among many of the PPP initiatives in the healthcare space under SBIRI are as follows:

Besides, Indian pharmaceutical majors like Dr. Reddy’s Laboratories (DRL), Reliance Life Science, Shantha Biotech, Ranbaxy, Biocon, Wockhardt and Glenmark have made good investments in biotech drugs manufacturing facilities keeping an eye on the emerging opportunities with Biosimilar drugs in the developed markets of the world.

Funding remains a critical issue:

That said, many industry experts do feel that R&D funding for the Biotech sector in the country is grossly inadequate. Currently, there are not many ‘Venture Capital’ funds for this sector and ‘Angel Investments’ almost being non-existent, Indian biotech companies are, by and large, dependent on Government funding.

Making India a global hub for biosimilar manufacturing:

However, with around 40 percent cost arbitrage, adequate government support and without compromising on the required stringent international regulatory standards, the domestic ‘biologic’ players should be able to establish India as one of the most preferred manufacturing destinations to meet the global requirements for particularly ‘biosimilar drugs’.

Experience in conforming to stringent US FDA manufacturing standards, having largest number of US FDA approved plants outside USA, India has already acquired a clear advantage in manufacturing high technology chemical based pharmaceutical products in India. Significant improvement in conformance to Good Clinical Practices (GCP) standards will offer additional advantages.

Conclusion:

With increasing support from the government and fueled by creative, scientific and technological inputs from various experts and entrepreneurs in the country, India has the potential to emerge as one of Asia’s best powerhouses in the field of biosimilars drugs by the end of this decade. It will take ‘two to tango’.
