Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) announced today that Chugai Pharma Taiwan Ltd., a wholly owned subsidiary of Chugai, launched Hemlibra^®, a new drug created by Chugai for routine prophylaxis of bleeding episodes in patients with hemophilia A with factor VIII inhibitors administered once weekly by subcutaneous injection.

“At present, Hemlibra is used by more than 4,000 people with hemophilia A worldwide. We are pleased that Hemlibra is now available for people with hemophilia A with factor VIII inhibitors in Taiwan,” said Chugai’s Executive Vice President, Co-Head of Project & Lifecycle Management Unit, Dr. Osamu Okuda. “Chugai will cooperate with Chugai Pharma Taiwan so that Hemlibra may contribute to people with hemophilia A with inhibitors in Taiwan as a new treatment option.”

About Hemlibra
Hemlibra is a bispecific monoclonal antibody, which was developed using Chugai’s proprietary antibody engineering technologies. The drug is designed to bind factor IXa and factor X. In doing so, Hemlibra provides the cofactor function of factor VIII in people with hemophilia A, who either lack or have impaired coagulation function of factor VIII^{1, 2)}. Hemlibra is approved in more than 90 countries, since the product has been approved for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients with hemophilia A (congenital factor VIII deficiency) with factor VIII inhibitors for the first time in the world by the U.S. Food and Drug Administration (FDA) in November 2017.
