A biosimilar is a biological product that closely mimics and is identical to a previously approved reference product. These are less expensive than branded or certified items. Several oncology biologics have already lost their patents, and others are about to expire. Biosimilars are predicted to gain popularity as more products lose their patents. Leading generic companies including Allergan Plc., Teva Pharmaceutical Industries Ltd., Mylan N.V., and Sandoz (a Novartis International AG division) are likely to benefit from these patent expirations and position themselves as market leaders in oncology biosimilars.
