India needs ‘Orphan Drugs Act (ODA)’ to counter growing threat of dreaded rare diseases and simultaneously boost global growth potential of the Indian Pharmaceutical Industry

An orphan disease is a rare and uncommon disease and an ‘Orphan Drug’ is a pharmaceutical substance that has been developed to treat an orphan disease. The US FDA defines a rare disease, with a prevalence of 1 in 5,000 of the general population, whereas in the European Union (EU) defines it as a disease with a prevalence of 5 in 10,000 of the population.

Around 6-8% of the world population is manifested by such rare diseases. There are around 5000 of reported rare diseases with an ascending growth trend.

Despite such trend, high drug development cost coupled with low return on investment, do not encourage many innovator pharmaceutical companies to get engaged in R&D initiatives for such drugs. However, this perception is fast changing, as we shall see below.

US took the first step to encourage commercialization of ‘Orphan Drugs’:

Public awareness drives for ‘Orphan Diseases’ first originated in the USA with the formation of a rare disease support group representing around 200,000 patients suffering from such diseases. This awareness campaign ultimately culminated into a path breaking legislation in the US named, ‘Orphan Drugs Act’ (ODA), in 1983. The key purpose of ODA was to incentivize initiatives towards development of such drugs to treat around 25 million Americans suffering from ‘Orphan diseases’. The incentives included:

- Funding towards investigation for “Orphan Disease’ treatment
- Tax credit for Clinical Research
- Waiver of fees for New Drug Application (NDA)
- Offering more lucrative incentive than product patent (product patent requires the drug to be novel), as the orphan designation of the product by the US FDA and product approval by them are the only requirements for 7 year market exclusivity of an ‘Orphan Drug’ for the same indication.
- Market exclusivity of ‘Orphan Drugs’ become effective from the date of regulatory approval, unlike product patent, product development time remains outside this period.
- The drugs, which are not eligible for product patent, may be eligible for market exclusivity as an ‘Orphan Drug’ by the US-FDA

Thanks to this Act, currently around 230 ‘Orphan Drugs’ are available in the US for the treatment of around 11 million patients suffering from rare diseases. With the help of ‘Human Genome Project’ more orphan diseases are expected to be identified and newer drugs will be required to treat these rare ailments of human population.

1983 signaled the importance of ‘Orphan Drugs’ with the ODA in the US. A decade after in 1993, Japan took similar initiative followed by Australia in 1999. Currently, Singapore, South Korea, Canada and New Zealand are also having their country specific ODAs.

India needs ODA:

Unfortunately in India, we do not have any ODA, as of now. Such legislation could give a new fillip to the Indian Pharmaceutical and Bio-Pharmaceutical industry and at the same time usher in a new hope to thousands of patients suffering from rare diseases in India, with the availability of relatively lower cost medications to them.

The global market:

The global market of ‘Orphan Drugs’ is expected to grow to US $ 112 billion in 2014 from US $85 billion in 2009. Biotech products contribute around 70% of this turnover with relatively higher CAGR growth rate of around 7%. However, reluctance of the insurance companies to cover ‘Orphan Drugs’ due to higher price still remains a global issue.

Orphan drugs to create a paradigm shift in the Pharmaceutical Industry: says Frost & Sullivan:

“While the pharmaceutical industries have been focusing on ‘blockbuster’ small molecules (chemical drugs) for high revenue generation in the past, it is expected that in 5 years, around $90.0 billion worth of branded drugs will lose their exclusivity. The current economic situation plus the huge generic competition shifted the focus of pharmaceutical companies and they are moving to a new business model – ‘Niche busters’, also called Orphan drugs.”

It is believed that Orphan drugs will now offer an attractive opportunity to the pharmaceutical companies than ever before to significantly absorb the impact of the ‘Patent Cliff’. Various financial incentives provided by the governments of various countries under the ODA coupled with many smaller collaborative projects towards this direction will further encourage the global pharmaceutical players to develop ‘Orphan Drugs.

Currently, EU has granted over 700 ‘Orphan Designations’ and over 60 new drugs have received favorable response for Market Authorization.

Sales potential for ‘Orphan Drugs’:

Generally ‘Orphan Drugs’ were not expected to be very high revenue earners. However, about 4 year ago in the year 2006, about 50 ‘Orphan Drugs’ were reported to had crossed a sales turnover of US $200 million. In 2006 the following ‘Orphan Drugs’ with expired market Exclusivity in the US, had assumed blockbuster status:

- Enbrel (Immunex): US $ 4.38 billion
- Rituxan (Genentech): US$ 3.97 billion
- Nupogen/Neulasta (Amgen): US $ 3.92 billion
- Epogen (Amgen): US $ 2.50 billion
- Avonex (Biogen): US $ 1.70 billion
- Betaseron (Novartis & Bayer): US $ 1.33 billion
- Intron A/ PEG-Intron (Schering): US $ 1.07 billion
- Kogenate (Bayer): US $ 1.07 billion
- Ceredase/Cerezyme (Genzyme): US $ 1.00 billion

Key growth drivers for ‘Orphan Drugs’:

In my view the following key factors will play critical role in driving the growth for ‘Orphan Drugs’:

- Market exclusivity options for a number of FDA recognized ‘Orphan Indications’ for the same drug
- Market exclusivity for seven years in the U.S. and ten years in the EU for each of the ‘Orphan Indications’
- Oncology could be a good segment to get such multiple ‘Orphan Indications’ for the same molecule

Glivec of Novartis obtained approval for around five new ‘Orphan Indications’, the key indications being Chronic Myelogenous Leukemia (CML) and Gastrointestinal Stomal Tumors. The product has already assumed a global blockbuster status with an estimated sales turnover of over US $4 billion by 2011.

Biotech companies are champions for the development of ‘Orphan Drugs’, globally:

Since long, the Biotech companies are taking initiatives for the development of ‘Orphan Drugs’. The path breaker in this respect was Genentech of the US, which developed two growth hormone molecules with names Protophin and Nutrophin, way back in 1985. Now, having realized the hidden potential of this segment more number of pharmaceutical players are entering into this arena. Thus, it is no wonder that 13 out of 19 blockbuster ‘Orphan Drugs’ were biologics in the year 2006.

Conclusion:

It is interesting to note that some of the ‘orphan diseases’ are now being diagnosed in India, as well. As India takes rapid strides in the medical science, more of such ‘Orphan Diseases’ are likely to be known in our country. Thus the moot question is how does India address this issue with pro-active measures?
Currently, India is curving out a strong niche for itself in the space of biogenerics. Pfizer-Biocon deal will vindicate this point.

Moreover, with Pharmacogenomics keep gaining ground at a faster pace, as I mentioned earlier, there will be a shift towards personalized medicines, in not too distant future, in which case the blockbuster drugs as defined today, will be effective only for a smaller number of patients. If the Government of India visualizes this scenario sooner, and comes out with appropriate ODA for the country, domestic pharmaceutical industry of India, in general and biopharmaceuticals industry of the country, in particular, will be able emerge as a force to reckon with, in this important global space, much faster than what one would currently anticipate.

Recent appetite of Global Pharmaceutical Majors for Generic Pharmaceutical Business: can it pose a threat to pure generic players?

Last year Lehman Brothers estimated that by 2012 over 25% of the global pharmaceutical market will face competition from generics. Higher demand of generics is mainly due to the following reasons:1. Increased number of patented drugs is going off-patent.2. Cost containment and pricing pressure, especially from the Government, in the developed markets of the world.

3. Increasing number of patents is being challenged, especially in the U.S courts, on the ground of “obviousness”.

“Obviousness” is becoming a key reason of patent challenges in the U.S:

In first quarter of the last year we read about the U.S trial court making void the key patent of Yasmin, the contraceptive drug of Bayer for ‘obviousness’. This incident had compelled Bayer to revise its profit forecast downwards, for 2008.

‘Obviousness’ is increasingly becoming one of the key reasons for challenging Patents in many countries of the world, including India. Financial Times reported recently that keeping protection to all patents intact, could eventually pose to be a key challenge for the R&D based global pharmaceutical companies. Many analysts feel that the issue of “obviousness” could indeed be a threat to many U.S pharmaceutical patents, especially those, which will be considered by the court just as a ‘tweaked-up’ version of existing drugs.

As reported by ‘Chemical Weekly’, March 2008, total 338 patent challenges were recorded globally in 2008. India ranks only next to USA with a share of 21% pharmaceutical patent challenges.

Global generic pharmaceutical market is growing at a faster pace:

Prescription market in the U.S grew by just 1.3% last year to U.S$291 billion. Key factors believed to be responsible for slower growth in the U.S market are as follows:

1. Higher prescriptions for less expensive generic medicines.

2. Lower sales of higher priced new products.

3. Economic downturn has made more patients to move to generics and large number of consumers to lose their health insurance.

Similarly in the United Kingdom (U.K) generics industry supplies 64% of medicines dispensed by the National Health Scheme (NHS), though they contribute just around 30% of NHS expenditure towards medicines.

Recent reports indicate that the generic global pharmaceutical market is expected to record a turnover of U.S$ 520 billion by 2012. This market size is too lucrative to ignore by any big global pharmaceutical player.

Based on sales turnover of 2007, Teva tops the list of global generic players with a turnover of U.S$ 9.1 billion, followed by Sandoz with U.S$ 5.8 billion and Mylan/Merck with U.S$ 4.6 billion.

From India, Ranbaxy registered a turnover of U.S$ 1.7 billion, Dr.Reddy’s U.S$ 1.4 billion, Cipla U.S$ 1 billion and Sun Pharma/Taro U.S$ 900 million, during that year.

48% of the total 422.6 million prescriptions written in Canada in 2007 were for generic medicines, which registered an annual growth of 14%, reports IMS Canada. Compared to this performance, branded products in Canada recorded a growth of meager 0.2%, during this period. As a consequence, generic Canadian pharmaceutical companies like Novopharm (Teva) and Apotex recorded impressive growth of 46.8% and 18.5%, respectively, in that period.

Despite such outstanding performance of generic pharmaceuticals, overall growth of prescription drugs in Canada was at just 6.3%, the lowest in the last ten year period.

President Obama’s Healthcare Policy will encourage generics and biosimilar drugs:

It is widely believed that the new U.S administration under President Barak Obama will try to encourage speedy introduction of generics into the U.S market.

So far as ‘Biosimilar’ drugs are concerned, in 2009 Obama administration is expected to work out the road map to facilitate the introduction of ‘Biosimilar dugs’ in the U.S market. Due to inherent characteristics that biological are ‘grown and not just manufactured’, biosimilar drugs are not expected to be replica of the original products.

To find out a solution to the heated debate, an answer has to be found out regarding the extent of clinical trials that the ‘biosimilar’ manufacturers will require to undertake to satisfy the U.S FDA that these drugs are as safe as the original ones. It is believed by some that the answer to this question lies in the approach that gives regulatory authority the flexibility in ‘what it demands that asks for more evidence than is now required for generic drugs, but something less than the kind of full-blown trials required for products new to the market.’

Global pharmaceutical majors are developing appetite for generics business:

Keeping a close vigil on these developments, as it were, even Pfizer, the largest pharmaceutical player of the world, has started curving out a niche for itself in the global market of fast growing generics, following the footsteps of other large global players like Novartis, GlaxoSmithKline, Sanofi-Aventis and Daiichi Sankyo.

Is Pfizer planning to follow the business model of Abbott and Johnson & Johnson (J&J)?

As reported by the Wall Street Journal (WSJ), Mr. Kindler the CEO of Pfizer very recently commented, “We are breaking the company down into smaller units so we aren’t dependent on any single product… I am a great admirer of J&J and Abbott’s business model.”

It appears what Mr. Kindler perhaps meant by this statement is that smaller business units, like Over the Trade Counter (OTC), Vaccines, Nutrition and Animal Health can be more ‘manoeuvrable and innovative’ for faster business growth. Acquisition of Wyeth could actually help Pfizer to implement this business model.

Coming back to generic business, the recent collaborative arrangement of Pfizer with Aurobindo Pharma in India vindicates Pfizer’s recent appetite on generic global pharmaceutical business. The company is already in this business with some of its off patent products. But now like others, Pfizer seems to be strategizing to reap a rich harvest from fast-growing generic pharmaceutical business through most probably its “Established Products” business division.

Could such business model of Global Pharmaceutical majors pose a threat to pure generic players in the business?

The entry of the global pharmaceutical majors into generic pharmaceutical business, in my view, could pose a serious threat to current generic players in the business, including those who are operating from India in the ‘regulated markets’ of the world, for the the following reasons:

1. Generic pharmaceutical business is usually a high volume, relatively low margin and highly competitive business. To survive in this business of cut-throat competition will require both financial and innovative marketing expertise, as well as financial and marketing muscle, where large global players are expected to easily score over others.

2. Product price of generics of the same or similar molecules being within a price band, prescribers and payors’ preference are expected to be in favour of large global pharmaceuticals, because of corporate brand image.

3. In future, the pharmaceutical marketing model, in my view, is expected to shift from ‘marketing of only medicines’ to ‘marketing of a bundle of medicines and services’. In the changed scenario global pharmaceutical majors are expected to have a distinct strategic advantage.

4. Global Pharmaceutical majors may also use this business model as a ‘preventive strategy’ to restrict market entry of number of players for an off-patent molecule and thereby effectively contain the extent of price erosion, as the brands will go off-patent.

It will, therefore, be quite interesting to watch, what happens in the global generic pharmaceutical business in the next five to ten years. I expect a significant consolidation taking place in this market, both global and local.
