GENEVA, Switzerland and BOSTON, MA – May 6, 2021 – ObsEva SA OBSV (SIX: OBSN) (ObsEva or the Company), a biopharmaceutical company developing and commercializing novel therapies to improve women's reproductive health, today reported financial results for the quarter ended March 31, 2021 and provided a business update.

"The outset of 2021 was marked with a prioritization of capitalization and commercialization, and we have made significant progress on both fronts," said Brian O'Callaghan, CEO of ObsEva. "In the first quarter of 2021, we raised over $60 million in gross equity proceeds, providing the capital needed to continue to advance our pipeline, reach multiple clinical and regulatory milestones, and execute on our well-defined strategic plan. On the commercialization front, we have created significant optionality and momentum with numerous negotiations that have reached an advanced stage. We plan to build on this momentum and select the best potential partners and strategies for each of our programs and look forward to providing additional updates in due course."

Anticipated Milestones

ObsEva aims to achieve the following key clinical and regulatory objectives in 2021:

• Yselty for uterine fibroids: NDA submission (Q3:21); MAA approval recommendation (Q4:21)
• Yselty for endometriosis: Phase 3 EDELWEISS 3 primary endpoint readout (Q4:21)
• Ebopiprant for treatment of preterm labor: Phase 2b dose ranging study initiation in EU/Asia (Q4:21)
  
  

Pipeline Update

Yselty for the treatment of uterine fibroids and endometriosis

• Yselty for Uterine Fibroids:   ObsEva is developing Yselty, an oral GnRH receptor antagonist with the potential to treat more women due to its potential best-in-class efficacy, a favorable tolerability profile and unique, flexible dosing options for the treatment of uterine fibroids. Following the European Medicine Agency's (EMA) validation of the marketing authorization application (MAA), a major milestone toward making Yselty available in the EU, the Company continues to work closely with the EMA to achieve marketing approval, with an approval recommendation from the Committee for Medicinal Products for Human Use (CHMP) projected in Q4:2021 and formal product approval expected to follow shortly thereafter. The Company is also working to submit a U.S. New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA), projected in Q3:2021, that will include the Week 76 post-treatment follow-up results from the Phase 3 PRIMROSE 1 (US only; n=574) and PRIMROSE 2 (Europe and US; n=535) clinical studies. In addition, the Company recently announced commencement of an observational study (PRIMROSE 3) of bone mineral density in women who completed at least 20 weeks of treatment in either of the PRIMROSE 1 or 2 studies.
  
  

• Yselty for Endometriosis: The EDELWEISS 3 study in the EU is progressing as planned, with randomization of patients recently completed and primary endpoint data expected in Q4:2021. The ongoing Phase 3 EDELWEISS 3 study (Europe and US) is designed to enroll approximately 450 patients with endometriosis-associated pain, with a co-primary endpoint of response on both dysmenorrhea (menstrual pain) and non-menstrual pelvic pain. The study includes a 75 mg once-daily dose without hormonal ABT (1 mg estradiol / 0.5mg norethindrone acetate), and a 200 mg once-daily dose in combination with hormonal ABT. Subjects who have completed the initial six-month treatment period will have the option to enter a six-month treatment extension.
  
  

Ebopiprant for Treatment of Preterm Labor:   Preparations are ongoing to initiate a Phase 2b clinical study in Q4:21. The Phase 2b dose ranging study will build on the recently announced PROLONG Phase 2a proof-of-concept study, which demonstrated early clinical efficacy and safety in pregnant women with spontaneous preterm labor. Given ebopiprant is currently the only known product in development for this indication and based on its innovative mechanism of action and positive topline data, the Company plans to discuss with European regulators a possible accelerated registration program based on a Phase 2b/3 adaptive design.    In parallel with development of ebopiprant in Europe and Asia, the Company is also actively evaluating the regulatory strategy for ebopiprant development in the United States, where there are currently no FDA-approved tocolytic medications available for treatment of preterm labor.

Nolasiban for In Vitro Fertilization:   ObsEva is also advancing nolasiban, an oral oxytocin receptor antagonist, to improve live birth rates in women undergoing in vitro fertilization.
