JOINT PROMOTION AGREEMENT ON ANTIEMETIC AGENT WITH HELSINN THERAPEUTICS INC. IN THE UNITED STATES REVISED
Eisai to Return All Rights to Promote and Distribute AKYNZEO® (netupitant/palonosetron) to Helsinn Therapeutics Inc.

Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that its U.S. subsidiary Eisai Inc. has agreed to revise the joint promotion agreement with Helsinn Healthcare S.A. (Headquarters: Lugano, Switzerland, Group Vice Chairman and CEO: Riccardo Braglia, “Helsinn”) for their chemotherapy-induced nausea and vomiting (CINV) franchise.

Under the new arrangement, from April 1, 2016, Helsinn Therapeutics Inc., the U.S. affiliate of Helsinn (“Helsinn U.S.”), will obtain exclusive rights to promote and sell AKYNZEO (netupitant/palonsetron), its oral fixed dose combination product for the prevention of CINV. AKYNZEO had previously been co-promoted in the United States by both Helsinn U.S. and Eisai Inc. As part of the revised agreement, Eisai and Helsinn U.S. will continue to co-promote ALOXI® (palonosetron HCl) injection in the United States for CINV.

Moving forward, Eisai Inc. will focus on further contributing to patients with ALOXI through this revised joint promotion agreement with Helsinn U.S., along with Eisai’s in-house anticancer agents Halaven® and Lenvima®.
