Astellas Pharma Inc. announced topline results from the Phase 3 SKYLIGHT 4 clinical trial investigating the long-term safety of fezolinetant, an investigational oral, nonhormonal compound being studied for the treatment of moderate to severe vasomotor symptoms associated with menopause (VMS) which will support future regulatory filing submissions.

Astellas Pharma studied the potential of fezolinetant, a selective neurokinin-3 receptor (NK3R) antagonist, against hot flashes in a series of double-blinded and placebo-controlled trials.

With a $425 million upfront payment, Bayer bolstered the company’s women’s healthcare pipeline with the acquisition of U.K.-based KaNDy Therapeutics and an investigational treatment for menopause.
