Amgen/Allergan Score Positive EMA Evaluation, but Launch Will Be Delayed

A couple of noteworthy pieces of news have emerged from across the pond on the biosimilar front. The first involves progress for Amgen’s application for its bevacizumab biosimilar at the European Medicines Agency (EMA). Its drug evaluation arm, the Committee for Medicinal Products for Human Use, recommended approval of the biosimilar on November 9.

Assuming EMA final approval is received, however, Amgen and Allergan’s cancer treatment agent will not be marketed any time soon. The principal European patent is not set to expire until 2022.

In the US, Mvasi™ was approved by the Food and Drug Administration in September, but its launch is similarly delayed by patent litigation. The main US patents should expire in 2019 (Roche claims to hold 27 enforceable patents). Amgen had filed suit October 6 challenging the validity of the patents in question, but this case may not be heard until late 2018. Amgen has the option of launching “at-risk,” but it has not indicated that it will go this route. Otherwise, the earliest launch may be sometime in 2019.

Several other potential bevacizumab makers have already challenged the patents, according to other reports. These include Boehringer Ingelheim, Celltrion, Pfizer, and Samsung Bioepis.

In other related news…An announcement will be made on November 20 regarding where the EMA will relocate its headquarters as a result of the Brexit. The Agency will need to complete its move by March 31, 2019, when Britain’s divorce from the European Union is finalized.
