GENEVA, Switzerland and BOSTON, MA - March 5, 2021 - ObsEva SA (NASDAQ: OBSV) (SIX: OBSN), a biopharmaceutical company developing and commercializing novel therapies to improve women's reproductive health, today reported financial results for the year ended December 31, 2020 and provided a business update.

"2020 was a critical year for ObsEva as it marked the beginning of our transformation from a clinical stage company to one preparing for regulatory approvals and commercialization," said Brian O'Callaghan, CEO of ObsEva. "The clinical and regulatory achievements of 2020 provide a solid foundation upon which to prepare Yselty for market launch in uterine fibroids and further its development for endometriosis."

"Our accomplishments also provide the impetus for advancing ebopiprant for treatment of preterm labor into a Phase 2b dose ranging study later this year," continued Mr. O'Callaghan. "Given the potential for expedited approval for this program, we are already beginning planning for its regulatory submission and commercialization. And though we have recently extended our cash runway into Q2 2022, we remain focused on securing further sources of long-term funding as well as suitable commercialization partners. Given the very positive outlook for ObsEva, our entire team is excited about the coming year and what the long-term future holds."

Anticipated Milestones

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

• Yselty for uterine fibroids: NDA submission (Q2:21); MAA approval (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 Uterine Fibroids:ObsEva is developing Yselty, an oral GnRH receptor antagonist with the potential to treat more women thanks 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) recent validation of the marketing authorization application (MAA), a major milestone toward making Yselty available in the E.U., the Company will continue to work closely with the EMA to achieve marketing approval, projected in Q4:2021. Meanwhile, the Company is also working to submit a U.S. New Drug Application (NDA), projected in Q2:2021, 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.
  
  
• Yselty for Endometriosis:The EDELWEISS 3 trial in the EU is progressing as planned, with primary endpoint data expected in Q4:2021. The ongoing Phase 3 EDELWEISS 3 study (Europe and US) was 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, and a 200 mg once-daily dose in combination with hormonal ABT (1 mg E2 / 0.5mg NETA). Subjects who completed the initial six-month treatment period will have the option to enter a six-month treatment extension.
  
• Ebopiprant for Treatment of Preterm Labor:A key objective for 2021 will be to initiate a Phase 2b clinical study, which will build on the recently announced positive topline data from the PROLONG Phase 2a proof-of-concept study by initiating a late-stage clinical development program. Based on the unmet need, ebopiprant's innovative mechanism of action and positive topline data regarding early clinical efficacy and safety in pregnant women with spontaneous preterm labor, and with no other known compound under development for this indication, the Company plans to discuss with European regulators a possible accelerated registration program based on a Phase 2b/3 adaptively designed trial.
  
  
• 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.
  
  

Financial Update

Cash Position: As of December 31, 2020, ObsEva had cash and cash equivalents of $31.2 million, compared with $69.4 million as of December 31, 2019. In January and February 2021, ObsEva received additional net proceeds of $55.6 million from equity issuances via its At-The-Market (ATM) program and exercises of warrants that were issued in connection with ObsEva's underwritten equity offering completed in September 2020. ObsEva believes its available cash and cash equivalents are sufficient to fund its planned operations (not including commercialization) into Q2:2022. The Company is actively exploring potential sources of non-dilutive or hybrid funding, including strategic partnerships and structured financing related to its further proposed development and commercialization efforts.
