Biosimilars
The biosimilars landscape
There is obviously a market for biosimilars. This is driven by the cost savings to be made by payers and patients alike. By 2015, IMS Health (IMS) expects spending on biosimilars to exceed US$2 billion annually, or about 1% of total global spending on biologicals. They expect new biosimilars to enter the US market by 2014 and European markets to have additional biosimilar molecules introduced during this period [1].
Sanofi announces new long-term objectives
At a ‘strategy and outlook’ seminar for investors held on 6 September 2011, sanofi-aventis (sanofi) CEO Mr Christopher A Viehbacher commented on the group’s outlook. The group has undergone radical changes since 2008, when it was faced with losing several blockbuster drugs over a relatively short time period, the so-called ‘patent cliff’. The main action sanofi took was to buy biotech company Genzyme and thus gain access to the biosimilars, rare diseases and multiple sclerosis markets. However, other actions not so interesting to the media have also played a great part in the company’s repositioning.
EMA comparability studies limiting biosimilar success
The EMA’s comprehensive biosimilar regulatory pathway, which includes the need for new clinical trials and comparability studies that demonstrate quality, efficacy, and safety, is a barrier for the development of clinically superior compounds, according to innovation researchers at Utrecht University, Utrecht, The Netherlands [1].
Biosimilars: barriers to entry and profitability in the EU and US
The implications of the US biosimilars law and the pending patent expiries of the 12 major biological products in the EU and the US will have an impact on the profitability and viability of the biosimilars industry [1].
The market for global and European biosimilars
Due to expiring patents for brand name products, cheaper generics are expected to grab market share [1]. This is not surprising due to the list of blockbuster drugs losing their patent protection in 2011 and 2012. These include the world’s best-selling drug, Lipitor (atorvastatin), which in 2010 had almost US$13 billion in worldwide sales, accounting for 15.8% of Pfizer’s total revenue [2].
Hospira looks to biosimilars and increased use of generics for growth
Injectable generics leader, Hospira, announced on 7 September 2011 at its investor day, that it will look to biosimilars and international expansion for future growth.
Five years of bioequivalence data from Cetero questioned
FDA is challenging five years of bioequivalence and other studies conducted at Cetero Research’s Houston facility in the US. This could affect both originator and generics companies alike, putting into question data provided to FDA to support new drug applications (NDAs) and abbreviated new drug applications (ANDAs).
Biosimilars and the pharmaceutical industry
IMS Health predicts a slowing down of the growth in annual spending on medicines, with generics being one of the main contributing factors for this reduction.
Positive results for phase I trial of biosimilar erythropoietin
Hospira, self-proclaimed leader in injectable generics, announced on 6 September 2011 positive results from a phase I clinical trial of its biosimilar erythropoietin (EPO) carried out in the US in patients with anaemia associated with chronic renal (kidney) failure and chemotherapy.
Opportunities for biosimilars in emerging markets
By 2015, IMS Health expects spending on biosimilars to exceed US$2 billion annually, or about 1% of total global spending on biologicals [1]. This growth in biosimilars will be driven mainly by patent expiries coming in the next five years. However, due to the complexity and cost of developing biosimilars for western markets many biosimilar manufacturers are turning to emerging markets as being a much more cost-effective solution.
