TOKYO, October 16, 2019 -- Oncolys BioPharma Inc. (hereafter, “Oncolys”) and Chugai Pharmaceutical Co., Ltd. (hereafter, “Chugai”) announced today that the Ministry of Health, Labour and Welfare (“MHLW”) officially accepted the application on October 15, 2019, jointly filed by both companies to change the designated applicant of the SAKIGAKE Designation for Telomelysin (OBP-301) (hereafter, “Telomelysin”) an oncolytic viral immunotherapy, in which both companies concluded an exclusive license agreement on April 8, 2019.

Oncolys initiated dosing of a corporate initiated Phase I clinical trial for Telomelysin-radiation combination therapy for esophageal cancer in July 2017. Both companies have entered into an agreement on April 8, 2019 that Oncolys will grant an exclusive license, with sublicensing rights, to Chugai concerning the development, manufacturing and marketing in Japan and Taiwan, as well as exclusive option rights concerning the worldwide development, manufacturing and marketing excluding Japan, Taiwan, China, Hong Kong and Macau to Chugai. On the same day, Telomelysin was granted SAKIGAKE Designation by MHLW. The acceptance of the change in designated applicant by MHLW is on the ground that the development of Telomelysin will be transferred from Oncolys to Chugai under the exclusive license agreement concluded between both companies in April 2019. Both companies will continue to work together to promote the development of Telomelysin.
