BRISBANE, Calif. and BASEL, Switzerland, Sept. 06, 2019 (GLOBE NEWSWIRE) — Myovant Sciences (NYSE: MYOV) today announced that its founding shareholder, Roivant Sciences, and Sumitomo Dainippon Pharma Co., Ltd. (TSE: 4506) (“Sumitomo Dainippon”), a leading global Japanese pharmaceutical company, have announced their entry into a non-binding memorandum of understanding for the creation of a broad strategic alliance. The Sumitomo Dainippon-Roivant Alliance (“Alliance”) is expected to create a new corporate entity which will be wholly owned by Sumitomo Dainippon and will assume Roivant’s ownership interest in Myovant Sciences.  The Alliance is expected to support Myovant Sciences through commercialization and profitability.  Roivant and Sumitomo Dainippon have stated that they expect to sign the definitive agreement for the Alliance by the end of October 2019.  The transaction will be subject to customary closing conditions and any required governmental approvals.

“We are excited to be part of this new Alliance which we believe would provide significant advantages for us as we prepare for the launch of relugolix,” said Lynn Seely, M.D., President and CEO of Myovant Sciences. “Our planned NDA filings and launch preparations for relugolix are well underway and we would benefit from the support we anticipate from the Sumitomo Dainippon-Roivant Alliance.”

Earlier this year, Myovant Sciences announced positive top-line data from two Phase 3 clinical studies, LIBERTY 1 and LIBERTY 2, evaluating relugolix combination therapy in women with uterine fibroids, as well as positive results from a separate bioequivalence study supporting a potential one pill, once-a-day dosing regimen of relugolix combination therapy. Myovant Sciences is on-track to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) by the end of this calendar year. Myovant also expects to announce topline results from its Phase 3 prostate cancer study later this year and results from its two Phase 3 endometriosis studies in the first and second quarters of calendar year 2020.
