Asahi Kasei Pharma announces that Doptelet® Tablet 20 mg (generic name: avatrombopag maleate), for which it obtained exclusive distribution rights in Japan from Swedish Orphan Biovitrum Japan Co., Ltd. (Sobi Japan), has been approved for the additional indication of persistent and chronic immune thrombocytopenia (ITP).

Avatrombopag, a thrombopoietin receptor agonist which stimulates the production of platelets, was approved in Japan in March 2023 for the indication of improving thrombocytopenia in patients with chronic liver disease who are scheduled to undergo an invasive procedure1. Sold in Japan by Asahi Kasei Pharma, avatrombopag has been approved for the treatment of chronic ITP2 in the U.S., Europe, and other markets.

By providing a new therapeutic option for persistent and chronic ITP, Asahi Kasei Pharma aims to realize a society where “no one should have to give up doing what they love due to illness” in accordance with its mission “to sincerely care for each individual life and solve their unmet medical needs with a wealth of ideas and solid science.”
