Regarding an oral antiviral drug (development number: S-217622) that selectively inhibits 3CL protease, enrollment has been completed in the Phase 2a Part of Phase 2/3 clinical trial and Phase 2b/3 Part is currently underway. Shionogi has completed the procedures for opening clinical trial sites not only in Japan but also in South Korea, Singapore, Vietnam, etc., and is accelerating patient enrollment. Shionogi will continue discussions with regulatory authorities so that Shionogi can provide this therapeutic drug in Japan and overseas as soon as possible. Regarding supply, Shionogi has already started commercial production, and there is no change in the plan to provide S-217622 for 1 million people by the end of FY2021.
