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:

No.	Company Name with Collaborator	Title of the Project Supported
1.	IcubedG Ideas Private Limited, New Delhi	Risk based Process Design for large scale Manufacturing of male injectable contraceptive (Phase I)
2.	Incozen Therapeutics Pvt. Ltd., Hyderabad	Discovery and Development of Novel, Selective and Potent Dihydroorotate Dehydrogenase Inhibitors in Inflammatory Bowel diseases. (Phase I)

12.	Avesthagen Limited, Bangalore	Scale-up and evaluation of high-value biosimilar product (Etanercept) aimed at providing cost-effective healthcare solutions to the emerging markets(Phase II)
13.	Bharat Serum and Vaccines Limited, Mumbai	Expression of recombinant proteins for development of synthetic pulmonary surfactant for Respiratory Distress Syndrome(Phase I)
14.	Cadila Pharmaceuticals Ltd., Ahmedabad	Development of Mycobacterium was an adjuvant for anti – rabies vaccine(Phase I)

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’.
