The companies will equally share profits and certain costs, while Myovant will record revenue. Myovant will also be responsible for interactions with the regulator and for drug supply and clinical development. The company will be entitled to $200 million in potential regulatory milestones for FDA approvals for relugolix combination tablet in women’s health, and to tiered sales milestones upon reaching up to $2.5 billion in net sales for prostate cancer and women’s health indications.
“There continues to be a high unmet need among the millions of women who experience the common and debilitating symptoms associated with uterine fibroids and endometriosis,” said Nick Lagunowich, global president, Pfizer Internal Medicine
Evercore analyst Josh Schimmer said the deal is positive for Myovant.
“After having some time to digest it, we like it,” Schimmer wrote in a note to clients. “While It gives up half the economics of relugolix (which we hadn’t modelled), that’s adequately offset by adding PFE’s commercial efforts as well as the billions of milestones which we think are achievable.”
