Spectrum Pharmaceuticals to Develop Biosimilar Rituximab
- Signs A Binding Letter Of Agreement With Viropro, Inc.
- 2009 Rituximab Sales Were Approximately $5.6 Billion Worldwide
IRVINE, Calif.--(BUSINESS WIRE)-- Spectrum Pharmaceuticals (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in oncology, today announced that it has signed a letter of agreement with Viropro, Inc., for the development of a biosimilar version of the monoclonal antibody drug rituximab (marketed by Genentech/Roche). Worldwide sales of rituximab in 2009 in all indications, including non-Hodgkin's lymphoma and chronic lymphocytic lymphoma, were approximately $5.6 billion.
"We are excited at the opportunity to develop our own proprietary biosimilar formulation of rituximab in anticipation of patent expirations for rituximab over the coming years," said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals, Inc.
Biosimilars, or follow-on biologics, are terms used to describe officially-approved subsequent versions of innovator biopharmaceutical products made by a different sponsor following patent and exclusivity expiry on the innovator product. Unlike the more common small-molecule drugs, biologics generally exhibit high molecular complexity and micro-heterogeneity. Biologics are also very sensitive to manufacturing process changes, including the choice of the cell type, production process, purification process and formulation of the biologic into a drug. In view of the complexity and sensitivity of the biologics to manufacturing process, no two biotech medicines can be exactly the same, hence the term "biosimilar." A number of biosimilar products are already in the market in Europe. Following enactment of the Biologics Price Competition and Innovation Act of 2009 (BPCI Act), an abbreviated approval pathway for biosimilars has been created in United States.
