ObsEva Announces Positive CHMP Opinion for Linzagolix, an Oral GnRH Antagonist, for the Treatment of Uterine Fibroids

Share

-European Commission Decision Anticipated in Q1 2022-

-CHMP recommendation follows the recent acceptance of the linzagolix uterine fibroids NDA by the U.S. Food and Drug Administration-

Ad hoc announcement pursuant to Art. 53 LR of the SIX Swiss Exchange

GENEVA, Switzerland December17, 2021 – ObsEva SA (NASDAQ: OBSV; SIX: OBSN), a biopharmaceutical company developing and commercializing novel therapies to improve women’s reproductive health, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending approval of linzagolix, an oral GnRH antagonist for the management of moderate to severe symptoms of uterine fibroids (UF) in adult women of reproductive age.

ObsEva’s Marketing Authorisation Application submission was based on positive data from the Company’s two Phase 3 PRIMROSE trials. If approved, linzagolix would be the first and only approved GnRH receptor antagonist with a non-hormonal option to address the needs of women who cannot or do not want to take hormones.

"The positive CHMP opinion is an important milestone for millions of women in the EU living with UF to address the diverse medical needs of the women who suffer from this condition,” said Brian O’Callaghan, CEO of ObsEva. “We will continue our productive, ongoing dialogue with EMA toward potential marketing authorization in the EU, and in parallel, continue to work with the FDA to advance linzagolix through the U.S. regulatory process.”

Jacques Donnez, M.D., Ph.D., a key opinion leader in gynecologic therapeutics commented, “While GnRH antagonists offer an exciting new, non-invasive alternative for the treatment of uterine fibroids, there is still the need for more individualized treatment options for the millions of women who may have a higher risk of contraindications to hormonal add-back therapy or ABT. If approved, linzagolix would be the only approved GnRH antagonist to provide flexible dosing options with and without hormonal ABTs to better address the individual needs of patients. Results from the PRIMROSE studies further underscore linzagolix’s differentiated profile and potential clinical utility. Additionally, the strong results on the full suppression dose (200 mg) with ABT showed that linzagolix could potentially offer best-in-class efficacy.”

The positive opinion adopted by the CHMP is based on 52-week treatment results from the Phase 3 PRIMROSE 1 (U.S. only; n=574) and PRIMROSE 2 (Europe and U.S.; n=535) clinical studies as well as supportive results from the 76-week post-treatment follow-up periods of both trials. Both studies evaluated full suppression (200 mg once daily) and partial suppression (100 mg once daily) doses of linzagolix, with and without hormonal add-back therapy (ABT).

PRIMROSE 1 and 2 successfully met their primary endpoints, with all doses showing statistically significant and clinically relevant reductions in heavy menstrual bleeding (HMB) compared to placebo. A number of important secondary endpoints were also met, including reduction in pain, rates of amenorrhea, time to reduced HMB and amenorrhea, and for the high dose without ABT, reductions in uterine and fibroid volume.

A final marketing authorization decision from the EC is anticipated within two months. The CHMP’s positive opinion follows the recent FDA acceptance for review of the uterine fibroids New Drug Application (NDA) (PDUFA date of September 13, 2022).

About the Phase 3 PRIMROSE Program in Uterine Fibroids
PRIMROSE 1 & 2 were prospective, randomized, parallel group, double-blind, placebo-controlled Phase 3 studies that investigated the efficacy and safety of two dosing regimens of linzagolix, 100 mg and 200 mg once daily, alone and in combination with hormonal ABT (1 mg estradiol and 0.5 mg norethisterone acetate) for the treatment of heavy menstrual bleeding associated with uterine fibroids. PRIMROSE 1 was conducted in the United States and enrolled 574 women. PRIMROSE 2 was conducted in Europe and the United States and enrolled 535 women. Both trials comprised a 52-week treatment period followed by a 6-month post treatment follow-up period. Additional information can be found here.

About Uterine Fibroids
Uterine fibroids are common benign tumors of the muscular tissue of the uterus. Uterine fibroids affect women of childbearing age and can vary in size from undetectable to large bulky masses.  Few long-term medical treatments are available.

The symptoms of uterine fibroids are wide-ranging and include heavy menstrual bleeding, anemia, pelvic pressure and bloating, urinary frequency and pain that can be extremely debilitating with a significant impact on quality of life. These symptoms can also have an impact on mental health, creating the additional burden of anxiety and distress.
