Indian biogenerics could form a major piece of the global biotherapeutics market in the future.
India's pharmaceutical manufacturers currently sell close to 30% of the world's generic therapeutics. Sales of generic versions of biologicals in India have grown rapidly, and that growth will likely expand into export sales over the next decade, according to the joint study, Advances in Biopharmaceutical Technology in India, (February 2008) by BioPlan Associates, Inc., and the Society for Industrial Microbiology.
Biogenerics represent a high-growth sector in India, where recombinant insulin, granulocyte cell stimulating factor (G-CSF), interferon alpha, erythropoietin (EPO), monoclonal antibody (MAb) products, and recombinant vaccines are manufactured by a number of domestic biotech companies. The costs of Western-made biopharmaceutical products places them out of reach of much of the world, and many of these products are close to losing their patent protections. To assist the Indian biotech industry in seizing this opportunity, the Indian government has streamlined some of its drug application and review procedures, and has offered strong tax incentives. As a result, India's biotech industry has been investing heavily in the development of facilities. It is expected that Indian biogenerics makers will soon receive their first approvals to manufacture products for the European market.
"Indian companies such as Biocon, Dr. Reddy's Laboratory, Intas Pharmaceuticals, MJ Biopharma, and others have the skills to develop and manufacture recombinant biotech products," says Ashesh Kumar, PhD, head of Medipolis GMP. These products include hepatitis B vaccine, streptokinase, human insulin, G-CSF, EPO, human growth hormone (HGH), interferon alpha-2a, and MAbs for cancer and Hodgkin's lymphoma.
Following the success of its generic pharmaceutical industry, Indian policy makers plan to repeat this in the biogeneric sector. Indian biotech revenues, currently at about $2 billion, are projected to reach $5 billion by 2010. Already, nearly 60% of these revenues are from exports.1 The year 2005 was an important milestone for Indian biotechnology as revenues crossed $1 billion.2
The success demonstrated by India's small molecule generic drug industry may not be a easily duplicated, however, for several reasons.
Yet, India seems intent on developing a world-class biotech capability. Even in the early 1980s, when Genentech and other American biotech companies were just beginning to make headlines, the Indian government initiated a program to promote its own biotech industry. In 1982, the National Biotechnology Board was set up under the Ministry of Science and Technology and became the Department of Biotechnology (DBT) in 1986. The DBT now spends close to $200 million annually to develop biotech resources in the country, including the expansion and improvement of academic programs, the development of more and better infrastructure, the nurturing of biotech companies, and the improvement of technology transfer to businesses from universities and other noncommercial laboratories.
This enthusiasm for biotech springs partly from an appreciation that biotherapeutics represent the future of medicine. But Indians also see in biotech an advanced, high-tech industry more in keeping with the image they expect of their country. Immensely proud of their world-class IT industry, Indians would like to mirror this in biotech, thus becoming "one of the nations to be counted" in the world community.3 And a natural step is for the country to become a major producer of generic biologics.
Blockbuster first-generation biotherapeutics developed in the West are already starting to lose patent protection in Western markets, and in the next decade, even second-generation products will begin to go off-patent. The biogenerics markets in Europe and the US together could amount to more than $15 billion in the next three years, at an average annual growth rate of close to 70%.
India's biogenerics industry remains relatively small, and nearly all of the products marketed now or in the near future are accounted for by a handful of companies (Tables 1 and 2). There are four main players.
Table 1. Biotherapeutics in India and their manufacturers
Biocon: India's first and largest biotech company was founded in 1978. Bangalore-based Biocon is now the largest biotech firm in Asia by market capitalization and the sixteenth largest worldwide. Biocon's existing biogenerics product line includes recombinant human insulin (Insugen), EPO (Erypro), G-CSF, and streptokinase. Most of Biocon's pipeline is now filled with innovative molecules, and it already markets a novel biologic, an anti-epidermal growth factor receptor (EGFR) MAb (BioMAB-EGFR) for head and neck cancers. As Biocon's CEO, Kiran Mazumdar-Shaw, told Fortune a year ago, "Unfortunately, [analysts] still tend to categorize us as a generics company...We keep saying, 'Look, we're not interested in generic companies, because we're trying not to be one.'"4
Table 2. Top biotech organizations in india by revenue
Dr. Reddy's Laboratories: India's third largest pharmaceuticals company, Dr. Reddy's was founded in 1984 in Hyderabad as a bulk pharmaceuticals manufacturer and soon grew to become one of India's best known generics makers. Among other ventures, Dr. Reddy's has manufacturing plants in the UK and a research facility in the US. The company currently markets only two biologics, both generics: Reditux, a version of Roche's blockbuster rituximab monoclonal against non-Hodgkins lymphoma; and Grafeel, a version of G-CSF. Dr. Reddy's announced in mid-2007 that it planned to invest $20 million to expand its biogenerics capability, and expected to roll out one new biogeneric product per year for the next eight years.5
Ranbaxy Laboratories/Zenotech: Founded in 1961, Haryana-based Ranbaxy is India's largest pharmaceutical company. It recently decided to move toward biogenerics by taking a large stake in Hyderabad-based Zenotech, an established biotech firm. The two companies now sell biogeneric versions of G-CSF and GM-CSF and have an Interleukin-2 generic, a recombinant HGH generic and a rituximab generic in clinical trials.
Shantha Biotechnics: Hyderabad-based Shantha, now 60% owned by Merieux Alliance, currently markets three biogenerics—an interferon alpha-2b, a streptokinase, and an EPO. The company's biogenerics pipeline includes a tPA product and a pegylated interferon for treating hepatitis C, although most of Shantha's research and development has been focused on new biologics and vaccines. Shantha has been making a recombinant-protein hepatitis-B vaccine since 1997.
Wockhardt: Based in Mumbai, Wockhardt currently has six biogenerics on the market in India: an EPO and a recombinant human insulin. Its pipeline includes an insulin glargine generic, interferon alpha 2b, and G-CSF.
New regulatory guidelines enable a streamlined clinical trials and review process under a single National Biotechnology Regulatory Authority.6 However, India's biogenerics manufacturers are less interested in India's market, or in other loosely regulated markets where consumers are relatively poor, than they are in the wealthy US and European markets.
The bioequivalence issue in the US is awaiting legislation that would amend Sec. 262 of the Public Health Service Act. Major healthcare legislation is unlikely in 2008, an election year, and passage of a standalone biogenerics bill is also unlikely, given the opposition by the Pharmaceutical Research and Manufacturers of America and other lobbying groups for innovator biotech companies.7 In late 2005, the EMEA gave final approval to basic guidelines for Similar Biological Medicinal Products.8 Since then, it has approved two growth hormone biosimilars, Sandoz's Omnitrope and Biopart-ners' Valtropin, in early 2006, as well as Sandoz's EPO biosimilar in August 2007.
The opening up of the European biosimilars market marks the end of the beginning of the biogenerics industry. Products made by India's biogenerics makers or their Western licensees will appear in European pharmacies as soon as their abbreviated clinical research requirements and EMEA reviews are completed successfully. Biogenerics will ultimately take, and keep, a significant chunk of the global biotherapeutics market, as biotherapeutics themselves take a larger portion of the global pharmaceuticals market.
But in the near term, the biosimilars market isn't as appealing as it might seem. The lack of US legislative action so far, the unlikelihood of action any time soon, and the evident opposition to such legislation, reduces the available market. And it is far from clear that when such legislation is enacted, it will include terms that make the follow-on biologics market attractive for India's generics makers.
Even in the European biosimilars market there is room for skepticism. Two of the first three approved biosimilars are competing against each other, and the more popular one of the two, Sandoz's Omnitrope, has so far captured less than 1% of the European HGH market, despite being priced up to 25% lower than the drug it was made to resemble, Pfizer's Genotropin.9
For Indian companies, a smaller piece of the pie may still be enough to justify their efforts. But some may elect to license development and marketing in Western markets to Western partners—as Biocon already has done for its G-CSF biogeneric—in advance of approval. And as Biocon's evolution also has shown, biogenerics may represent only a passing phase for some Indian biotech companies, who prefer to focus their R&D efforts on the creation of new and patentable biologics. Indeed, the same national pride that makes Indians want to excel at IT and biotechnology seems to make some of them anxious to outgrow the country's "cheap generics" reputation. Dr. Swati A. Piramal, director of an R&D center for Nicholas Piramal in Mumbai, was quoted not long ago as saying, "Indian companies are no longer going to be just copycats. We want to take our rightful place at the head table with the developed nations."10
