Dr. Masashi Miyamoto, Executive Officer, Director, Strategic Product Portfolio Department of Kyowa Hakko Kirin said “We are pleased to enter into a partnership with Syndax to develop Entinostat in Japan and Korea. Entinostat has great potential to treat a cancer with a mode of action modifying epigenetics,”We believe that Entinostat could deliver a lot of benefit to breast cancer and other cancer patients, which lead to strengthening KHK’s future oncology portfolio.” Arlene Morris, president and chief executive officer of Syndax, said, “Since we have already begun a registration-directed Phase III trial in breast cancer in the US, it’s important and timely to enter into this agreement with KHK to initiate development in order to bring entinostat to breast cancer patients in Japan and Korea.” “The expansion of the global development effort further validates the importance of prolonging survival in metastatic breast cancer as observed in our Phase II trial and underscored by the FDA designating entinostat a Breakthrough Therapy when combined with exemestane in postmenopausal women with HR+ metastatic breast cancer. Syndax is very pleased to be able to collaborate with KHK, a company with a strong track record of developing important therapeutic products.” Kyowa Hakko Kirin is planning to initiate clinical trials in 2015.
