Samsung Bioepis Signals a Settlement With Genentech on Herceptin Biosimilar

And then there was one. Samsung Bioepis and Genentech filed a motion in District Court to drop all pending patent litigation regarding Ontruzant®, an approved Herceptin® biosimilar. A Joint Stipulation of Dismissal is usually the confirmation that a licensing agreement has been reached.

This leaves one remaining approved trastuzumab biosimilar maker that has not settled with Genentech (a subsidiary of Roche). Amgen’s product Kanjinti®, which was the last trastuzumab biosimilar approved (in June), is the last of 5 approved agents that is not yet subject to a Genentech agreement. The other manufacturers, Mylan/Biocon, Teva/Celltrion, Pfizer, and now Samsung Bioepis, will likely pay a royalty to Genentech whenever their products are launched.

Launch dates have not been announced (nor have the terms of these agreements) for any Herceptin biosimilar. However, the principal patent for Herceptin® has expired, so biosimilar competition should be available before the end of the year.

In other biosimilar news…Coherus Biosciences announced that it has manufactured its 400,000th dose of its pegfilgrastim biosimilar Udenyca®. Additionally, its unaudited second quarter earnings seem to indicate positive movement, as much as $84 million (more than doubling first-quarter earnings of $37 million).
