EC approves Plexxikon's Zelboraf to treat BRAF mutation-positive MM

Plexxikon Inc., a member of Daiichi Sankyo Group, today announced that the European Commission has approved Zelboraf® (vemurafenib) for the monotherapy treatment of adult patients with BRAF^V600 mutation-positive unresectable or metastatic melanoma. The cobas 4800 BRAF V600 Mutation Test, a companion diagnostic used to identify patients with the BRAF mutation, is CE marked and commercially available in Europe. Zelboraf is designed to selectively inhibit the BRAF mutation that occurs in about half of all cases of melanoma.

Zelboraf and its companion diagnostic have already been approved in the United States, Switzerland, Israel, Brazil, New Zealand and Canada. In the United States, Zelboraf is being co-promoted by Daiichi Sankyo, Inc. and Genentech, a member of the Roche Group. Roche promotes Zelboraf outside of the United States.

"The approval of Zelboraf by the European Commission marks a significant advancement for European patients with metastatic melanoma who historically have had very limited treatment options," said K. Peter Hirth, Ph.D., chief executive officer of Plexxikon. "We are very pleased that our strategy to co-develop Zelboraf along with a companion diagnostic helped accelerate the availability of this personalized medicine for these patients."
