ObsEva Announces Positive Results from Uterine Fibroids Phase 3 Study (PRIMROSE 2) of Linzagolix - Seite 2

Dr. Hugh Taylor, Professor and Chair of Obstetrics and Gynecology at Yale University, said, “Women with uterine fibroids need non-surgical alternatives to reduce the often unbearable effects of heavy menstrual bleeding. The prospects for a medical treatment with multiple dosing options would address a need for this diverse population of women. I am particularly impressed with the 94% responder rate and 80% amenorrhea rate that linzagolix has shown.”
