GENEVA, Switzerland and BOSTON, MA (August 7, 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 second quarter ending June 30, 2019 and provided a business update.

Recent Highlights

Nolasiban to improve live birth rates in patients undergoing embryo transfer (ET) following IVF

• Completed patient enrollment during the second quarter in IMPLANT 4, the confirmatory Phase 3 trial for the oxytocin receptor antagonist nolasiban. Approximately 800 patients undergoing a Day 5 single embryo transfer following IVF were enrolled at approximately 40 sites, primarily in Europe.
• Presented positive Phase 3 IMPLANT 2 efficacy and safety results at the European Society of Human Reproduction and Embryology (ESHRE) Annual Meeting, held June 23-26 in Vienna.
• Made significant progress toward starting U.S. Phase 3 development at End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA).

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

• Presented positive efficacy and safety results from the Phase 2b EDELWEISS 1 trial of linzagolix for the treatment of endometriosis-associated pain at the ESHRE meeting.
• Initiated the Phase 3 EDELWEISS 2 (U.S.) and EDELWEISS 3 (U.S. and Europe) clinical trials in May 2019. These trials are planned to each enroll 450 women with endometriosis-associated pain, and include two oral doses of linzagolix, 75mg once daily without low-dose hormonal add-back therapy (ABT) and 200mg once daily with ABT.
• Completed patient recruitment in PRIMROSE 1, the U.S. Phase 3 trial for linzagolix in the treatment of uterine fibroids. The PRIMROSE 1 and PRIMROSE 2 trials include approximately 1,000 women in total with heavy menstrual bleeding (HMB) associated with uterine fibroids. The efficacy and safety of two oral doses of linzagolix are being studied, including 100mg once daily without ABT and 200mg once daily with ABT.

OBE022 for the treatment of preterm labor

• Completed enrollment of the first 30 patients in Part B of the PROLONG trial, a 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.
• In July 2019 the independent data monitoring committee (IDMC) for the PROLONG trial recommended continuing the trial with no modifications.

"This past quarter brought another major milestone for ObsEva with the initiation of our two Phase 3 trials of linzagolix for endometriosis-related pain," said Ernest Loumaye, co-founder and Chief Executive Officer of ObsEva. "We also advanced Phase 3 trials of linzagolix for uterine fibroids and the confirmatory European trial of nolasiban for improving outcomes in embryo transfer following IVF, both of which we expect will have primary endpoint readout in the fourth quarter of this year. We are on track to end the year with our most exciting milestone yet, the MAA filing of nolasiban."

2019-2020 Milestones

ObsEva expects to achieve the following clinical and regulatory milestones in 2019-2020:

Nolasiban

• In the fourth quarter of 2019, reporting of primary endpoint results (10-week ongoing pregnancy) for the Phase 3 IMPLANT 4 trial of nolasiban.
• In late 2019, assuming positive IMPLANT 4 results, submission of a European Marketing Authorization Application (MAA).
• In the third quarter of 2019, submission of an updated IND and Phase 3 trial protocol to the FDA for the Phase 3 IMPLANT 3 trial, and subsequently begin the trial in the fourth quarter of 2019 or first quarter of 2020.
