Shares of MEI Pharma traded higher after the company announced that it has entered into development and global licensing agreement with Kyowa Kirin for its oral selective PI3Kδ inhibitor (ME-401) used for treating B-cell malignancies.

Late-stage pharmaceutical company MEI Pharma Inc. (MEIP:NASDAQ), which is focused on developing potential new therapies for cancer, and Kyowa Kirin Co. Ltd.

MEI Pharma's COO & General Counsel David M. Urso commented, "This global partnership with Kyowa Kirin is a key step to achieving our goal of broadly developing and commercializing ME-401, optimizing the opportunity to benefit patients across multiple B-cell malignancies inside and outside the U.S., and also building value for our shareholders...The decision to expand our alliance with Kyowa Kirin is based on the successful relationship we've built working together to date under our 2018 Japan license agreement, and the respect we have for Kyowa Kirin and their ability to jointly execute our shared vision of ME-401 in the U.S. and around the world."

Tomohiro Sudo, executive officer, director of Strategic Product Planning Department for Kyowa Kirin, added, "I am delighted to expand our agreement with MEI Pharma for the development and commercialization of ME-401 all over the world...We believe that ME-401 may be an important new treatment option for patients and further enhances our global oncology pipeline."

The first study is the Phase 2 TIDAL trial evaluating ME-401 as a monotherapy for the treatment of adults with relapsed or refractory follicular lymphoma, and the second study is a Phase 1b dose escalation and expansion trial evaluating ME-401 as a monotherapy and in combination with other therapies or investigational agents in patients with relapsed or refractory B-cell malignancies.
