ME-401 is being studied in the ongoing Phase 2 TIDAL clinical trial evaluating patients with relapsed or refractory follicular lymphoma which, subject to results, may support an accelerated approval of a marketing application with the U.S. Food and Drug Administration (FDA). An ongoing Phase 1b study is evaluating ME-401 as a monotherapy and in combination with rituximab (Rituxan) or zanubrutinib (Brukinsa) in patients with B-cell malignancies. Also, a Phase 1 study was initiated in 2019 evaluating ME-401 as a monotherapy in patients with indolent B-cell malignancy in Japan.

"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," said David M. Urso, J.D., chief operating officer & general counsel of MEI Pharma. "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."

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

About the Global License, Development and Commercialization Agreement

Under the terms of the agreement, which substantially retains and consolidates the terms of the 2018 license agreement between MEI and Kyowa Kirin to develop and commercialize ME-401 in Japan, MEI will receive a $100 million upfront payment from Kyowa Kirin. MEI is also eligible to receive up to $582.5 million in additional payments from Kyowa Kirin depending on the achievement of certain U.S. and ex-U.S. development, regulatory and commercial milestones.

If approved by FDA in the U.S., MEI and Kyowa Kirin will co-promote ME-401, with MEI booking all revenue from sales. MEI and Kyowa Kirin will share U.S. profits and costs (including development costs) on a 50-50 basis.

Outside the U.S., Kyowa Kirin will have exclusive commercialization rights, lead commercialization and book all revenues from sales of ME-401. Kyowa Kirin will pay MEI escalating tiered royalties on ex-U.S. sales starting in the teens. Kyowa Kirin will be responsible for all incremental ex-U.S. clinical development costs and all ex-U.S. regulatory, CMC and commercial costs.

The companies have agreed to a development plan designed to broadly evaluate ME-401 in patients with various B-cell malignancies, including in combination with other agents.

About ME-401

MEI-401 is an investigational treatment and not approved by the U.S. Food and Drug Administration (FDA) or other Health Authorities. Clinical development of ME-401 as an oral, once-daily, selective PI3Kδ inhibitor for the treatment of B-cell malignancies is ongoing. The U.S. FDA recently granted ME-401 Fast Track designation.

MEI is currently conducting two ongoing studies evaluating ME-401. The first is a Phase 2 clinical trial evaluating ME-401 as a monotherapy for the treatment of adults with relapsed or refractory follicular lymphoma after failure of at least two prior systemic therapies including chemotherapy and an anti-CD20 antibody. Subject to the results, upon completion of the Phase 2 clinical trial, ME-401 is planned to be submitted with the FDA to support an accelerated approval of a marketing application under 21 CFR Part 314.500, Subpart H. The second study is a multi-arm, open-label, 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. Additionally, a Phase 1 study was initiated by Kyowa Kirin in 2019 evaluating ME-401 as a monotherapy in patients with indolent B-cell malignancy in Japan.
