Myovant Sciences (NYSE: MYOV) and Pfizer Inc. (NYSE: PFE) announced today that the U.S. Food and Drug Administration (FDA) has extended the review period for the supplemental New Drug Application (sNDA) for MYFEMBREE® (relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg) for the management of moderate to severe pain associated with endometriosis. The FDA requires extended time to review additional information the Agency requested from the companies regarding bone mineral density. The extended Prescription Drug User Fee Act (PDUFA) goal date is August 6, 2022.
“We remain confident in the clinical profile of MYFEMBREE and its potential to become a therapeutic option for the management of endometriosis-associated pain,” said Juan Camilo Arjona Ferreira, Chief Medical Officer of Myovant Sciences, Inc. “We will continue to work closely with the FDA to support the ongoing review of the sNDA.”
MYFEMBREE® was approved in the U.S. in 2021 for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women with a treatment duration of up to 24 months.
About Endometriosis
Endometriosis is a condition in which tissue similar to the uterine lining is found outside of the uterine cavity, which often causes disruptive symptoms like painful periods, fatigue, pain in the lower back and abdomen, heavy menstrual bleeding, and even painful or difficult sexual intercourse. For endometriosis-associated pain, current treatment options include prescription and over-the-counter pain medications, oral contraceptives, GnRH agonists, and antagonists. There are also surgical options including adhesiolysis, cyst removal, and hysterectomy.
Endometriosis can also impact general physical, mental, and social well-being, requiring a multi-disciplinary approach to care. Almost 200 million women suffer from symptoms of endometriosis globally. i In the U.S., there are approximately 7.5 million premenopausal women with endometriosis. ii,iii,iv It can take between four and eleven years to get an endometriosis diagnosis v,vi,vii,viii and for some women, current treatment options do not provide relief.
About MYFEMBREE®
