ObsEva Reports First Quarter 2019 Financial Results

2019 Phase 3 Data Readouts on track for nolasiban in IVF and linzagolix in uterine fibroids;

MAA submission for nolasiban IVF therapy targeted by year-end

GENEVA, Switzerland and BOSTON, MA. (May 9, 2019) – ObsEva SA (NASDAQ: OBSV / SIX: OBSN), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapeutics for serious conditions that compromise a woman’s reproductive health and pregnancy, today reported financial results for the first quarter ending March 31, 2019 and provided a business update.

Recent Highlights

Nolasiban to improve IVF outcomes

• ObsEva continued enrolling patients in IMPLANT 4, ObsEva’s confirmatory Phase 3 trial for the oxytocin receptor antagonist nolasiban in IVF.  Approximately 820 patients who are undergoing a Day 5 single embryo transfer will be enrolled at approximately 40 sites primarily in Europe.
• ObsEva reported final follow-up safety data from the nolasiban IMPLANT 2 trial.   The results showed no difference from placebo in the developmental health of infants at six months post-birth, as measured by the About Ages and Stages Questionaire-3 (ASQ-3), a broadly validated assessment of infant development.

Linzagolix for the treatment of endometriosis associated pain and heavy menstrual bleeding due to uterine fibroids

• ObsEva reported positive long-term data from the Phase 2b EDELWEISS trial of linzagolix in endometriosis. Some patients were treated for 52 weeks in the extension study and others were followed for six months off treatment after the initial six-month treatment period.  The results were consistent with prior data, showing durable efficacy as well as favorable bone mineral density impact within expected ranges for partial and full suppression of estrogen.
• ObsEva made strong enrollment progress in PRIMROSE 1, the Company’s U.S. Phase 3 trial for linzagolix in the treatment of uterine fibroids.  The PRIMROSE 1 and PRIMROSE 2 trials are targeting enrollment of approximately 1,000 women with heavy menstrual bleeding associated with uterine fibroids.  The efficacy and safety of two doses of linzagolix are being studied, including 100mg without low dose hormonal add-back therapy (ABT) and 200mg with ABT.

OBE022 for the treatment of preterm labor

• ObsEva announced encouraging Part A results leading to the initiation of Part B of PROLONG, a proof-of-concept Phase 2a trial of the oral prostaglandin F2 alpha receptor antagonist OBE022 for the treatment of preterm labor.  Part A results showed that OBE022 was well tolerated by mothers and their fetuses and supported prior favorable pharmacokinetic analysis.  Eight of nine patients achieved the treatment goal of seven-days without delivering a baby.
• Ongoing part B is the multicenter, randomized, double-blind, placebo-controlled portion of the trial that will enroll up to 120 patients with preterm labor at a gestational age of between 24 and 34 weeks.

“We are thrilled with our progress this past quarter as we advanced all three of our Phase 3 clinical programs, and have initiated two Phase 3 trials for endometriosis this year.  2019 is a transformational year for us as we work toward the MAA filing of nolasiban later this year. We are excited about developing our commercial capabilities in anticipation of a planned European launch in 2021,” said Ernest Loumaye, co-founder and Chief Executive Officer of ObsEva.
