Biosimilars
Manufacturing of biosimilars
Manufacturing of biosimilars is more challenging than the traditional small molecule generics. Some of the reasons are:
- Investments (including operating costs) associated with manufacturing of biosimilars along with the risk of failure for biosimilars are significantly higher than that for small molecule generics. This results in a relatively smaller discount for biosimilars compared to small molecule generics.
- Minor changes in manufacturing process can cause significant changes in efficacy or immunogenicity.
- Biosimilars are larger and more complex molecules to manufacture.
Partnerships will drive biosimilar development
With biosimilars tipped to become a multibillion-dollar market in the coming years, everybody is jumping on the biosimilars bandwagon, and it seems it’s not just limited to pharmaceutical companies.
Does industry support biosimilar user fees in the US?
According to FDA, biopharmaceutical trade groups are supportive of its proposal for biosimilar user fees, with sponsors paying an up-front fee with their applications.
Challenges ahead for biosimilar development
Biosimilars, it seems are here to stay, but there is still some way to go before they become commonplace. There is also concern over the associated costs for biological medicines. The cost of biotech therapies is expected to steadily grow by about 30% (an approximately 20 fold increase in 10 years) by 2016.
Market opportunities for biosimilars
Although growth in annual spending on medicines is set to reduce, there is still a huge market out there and spending on biosimilars is expected to increase in the coming years.
Caution over IP provisions for biologicals in TPP
The US Generic Pharmaceutical Association (GPhA) has expressed its concerns over negotiations currently taking place on the Trans-Pacific Partnership (TPP) agreement.
Merck enters biosimilars deal with Korea’s Hanwha
US pharma giant Merck announced on 13 June 2011 an exclusive deal with South Korea’s Hanwha Chemical Corporation to develop and commercialise a biosimilar version of Amgen and Pfizer’s blockbuster rheumatoid arthritis drug Enbrel (etanercept).
Mylan re-brands Matrix Labs to enter Indian market
US generics manufacturer Mylan announced on 27 May 2011 that it plans to rebrand its India-based subsidiary Matrix Laboratories as Mylan in order to launch its own prescription drugs in the emerging Indian market over the next year.
US approvals of biologicals doubled in last decade
Regulatory approvals for new biological drugs in the US have nearly doubled in the last decade compared with the 1990s, according to the May/June 2011 issue of the Tufts Center for the Study of Drug Development (CSDD) Impact Report. However, the author of the report, Research Assistant Professor Janice Reichert, said there are still ‘substantial challenges’ to be faced by biologicals manufacturers if they wish to ‘maintain that pace’.
Standards for biosimilars or ‘alternative’ biologicals in India
In the highly regulated market of the EU clear and rigorous guidelines exist for approval of biosimilars. In the EU biosimilars must ensure the same quality, safety and efficacy, as any other product, along with demonstrating biosimilarity (comparability) with the reference product.
