GENEVA, Switzerland – May 17, 2022 – 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 first quarter ended March 31, 2022 and provided a business update.

"We are eagerly anticipating the approval of linzagolix in Europe, which would mark our first product approval and a major achievement for ObsEva," said Brian O'Callaghan, CEO of ObsEva. "With the potential to be, if approved, the first and only approved GnRH antagonist with flexible dosing options with and without hormonal add-back therapy, we believe linzagolix could transform the standard of care for millions of women living with uterine fibroids. In the United States, the regulatory review process likewise remains on track, setting ObsEva up for multiple potential approvals this year. We are advancing launch preparations in both markets through our commercial agreements with Theramex and Syneos Health to fully realize the significant commercial potential of linzagolix, while continuing to evaluate strategic opportunities in women's health that could further enhance ObsEva's value."

Anticipated Milestones

ObsEva anticipates the following key clinical and regulatory objectives in 2022:

• Linzagolix for uterine fibroids: Prescription Drug User Fee Act (PDUFA) target action date of September 13, 2022, as set by the U.S. Food and Drug Administration (FDA); European Commission approval expected following confirmation in April of the Committee for Medicinal Products for Human Use (CHMP) positive opinion for the marketing authorization application (MAA).         
  
  
• Linzagolix for endometriosis: Additional data from the post-treatment follow-up of the Phase 3 EDELWEISS 3 trial as well as data from the long-term treatment in the extension study are expected in mid-2022, and from the post-treatment follow-up of the extension study in early 2023.        
  
  

Pipeline Update

• Linzagolix for Uterine Fibroids: ObsEva is developing linzagolix, an oral GnRH receptor antagonist with potential best-in-class efficacy, a favorable tolerability profile, and flexible dosing options for the treatment of uterine fibroids. The CHMP of the European Medicines Agency confirmed its positive opinion recommending approval of the linzagolix MAA at the April 2022 CHMP meeting. The European Commission is now reviewing the CHMP recommendation. If approved, linzagolix will be the first and only approved oral GnRH antagonist in uterine fibroids with a dosing option without additional hormonal add-back therapy (ABT) to address the needs of women who cannot or do not want to take hormones. In February 2022, ObsEva announced a strategic licensing agreement with Theramex to support the commercialization and market introduction of linzagolix across global markets outside of the U.S., Canada and Asia, and EU launch preparations are advancing. Theramex's extensive women's health commercial infrastructure includes a dedicated sales force of more than 180 experienced representatives across Europe, Brazil, and Australia, alongside third-party distributors across approximately 60 countries. In the United States, the New Drug Application (NDA) for linzagolix for uterine fibroids has been accepted for review by the FDA, with a PDUFA target action date of September 13, 2022. In October 2021, ObsEva announced a commercial sales agreement with Syneos Health to commercialize linzagolix within the United States. Syneos Health is a fully integrated biopharmaceutical solutions organization with significant experience in women's health launches. ObsEva's agreement with Syneos Health provides access to a dedicated sales force, marketing, medical affairs professionals, and market access in support of the linzagolix launch, if approved.
  
  

At the American College of Obstetricians and Gynecologists (ACOG) Annual Clinical and Scientific Meeting on May 6-8, additional data from the PRIMROSE Phase 3 studies of linzagolix for uterine fibroids was featured in an oral presentation and four posters. The analyses and post-treatment data continue to underscore linzagolix's clinical utility and differentiated profile.

• Linzagolix for Endometriosis: In January 2022, ObsEva announced positive topline results from the Phase 3 EDELWEISS 3 trial in women with moderate-to-severe endometriosis-associated pain. The 200 mg with hormonal add-back therapy (ABT, estradiol 1mg/norethindrone 0.5mg) dose met the co-primary efficacy objectives, demonstrating reductions in dysmenorrhea (DYS) and non-menstrual pelvic pain (NMPP) at 3 months. The 75 mg dose without hormonal ABT demonstrated a statistically significant reduction versus placebo in DYS at 3 months. Although the 75 mg dose without hormonal ABT showed improvement in NMPP at 3 months, it did not reach statistical significance versus placebo, and thus did not meet the co-primary efficacy objective. Both doses were generally well-tolerated and results support continued development of linzagolix, including further exploration of dose options without hormonal ABT. Additional efficacy results from the 6-month analysis of the Phase 3 EDELWEISS 3 trial were announced in March 2022, demonstrating rapid onset of treatment effect, positive impact on quality of life, and intentions for surgery. Further data from the post-treatment follow-up of the Phase 3 EDELWEISS 3 trial as well as data from the long-term treatment in the extension study are expected in mid-2022, and from the post-treatment follow-up of the extension study in early 2023.
  
  
  • Ebopiprant for Treatment of Preterm Labor: In July 2021, ObsEva granted a license to Organon (NYSE:OGN) for the global development, manufacturing and commercial rights to ebopiprant. Ebopiprant is an investigational, orally active, selective prostaglandin F2α (PGF2α) receptor antagonist being evaluated as a potential treatment for preterm labor by reducing inflammation and uterine contractions. ObsEva previously conducted clinical development through an ex-US Phase 2a clinical trial, where reduced deliveries in singleton pregnancies 48 hours after the start of dosing were observed. Under the terms of the agreement, ObsEva is entitled to receive tiered double-digit royalties on commercial sales as well as up to $500 million in upfront and milestone payments, including up to $90 million in development and regulatory milestones. ObsEva is working closely with Organon to discuss with the FDA the submission of an Investigational New Drug Application for ebopiprant anticipated in 2022 to enable clinical development in the United States.
    
    
  • 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. ObsEva has partnered with Yuyuan BioScience Technology for the development and commercialization of nolasiban in China.
    
    

Leadership Transition

• Dr. Brandi Howard was appointed as Chief Clinical Officer and member of the company's Executive Committee. Dr. Howard brings to ObsEva more than 20 years of expertise in women's health, with increasing responsibilities in medical affairs strategy and leadership, as well as leading large clinical development programs. Dr. Howard succeeds Dr. Elizabeth Garner, who departed ObsEva on May 6, 2022 to pursue a new opportunity. To help ensure a smooth transition, Dr. Garner has agreed to provide advisory consulting services to ObsEva on an as needed basis.         
  
  
  
  

Financial Results for the First Quarter Ended March 31, 2022

• ObsEva had cash and cash equivalents of $57.6 million at March 31, 2022 compared to $54.7 million at December 31, 2021. The increase of $2.8 million is primarily attributable to $5.7 million of net cash received during the first quarter 2022 from the utilization of its at-the-market offering program, $8.3 million in proceeds from the Company's securities purchase agreement with certain funds and accounts managed by JGB Management, Inc. (JGB), a $5.7 million upfront payment in connection with the Company's licensing agreement with Theramex, offset by cash used for operating activities.
• Operating income other than revenue was $2.2 million for the quarter ended March 31, 2022 compared to $6,000 in the prior year period. The increase was due to the partial recognition of the upfront payment associated with the Company's licensing agreement with Theramex, net of fees and recognition of the associated intangible asset.
• Research and development expenses were $5.6 million for the quarter ended March 31, 2022, compared to $15.5 million in the prior year period, representing a decrease of $9.9 million. The decrease was primarily due to decreased costs related to the development of linzagolix due to the timing of clinical trial activities.
• General and administrative expenses were $7.2 million for the quarter ended March 31, 2022 compared to $4.2 million in the prior year period, an increase of $3.0 million. The increase was attributable to professional fees associated with commercial launch preparation, insurance, and additional employee compensation costs; partially offset by lower legal fees.
• Finance result, net was $1.1 million for the quarter ended March 31, 2022, compared to $0.3 million for the prior year period. The increased expense was primarily due to higher interest costs related to ObsEva's borrowings under its securities purchase agreement with JGB.
• Net loss for the quarter ended March 31, 2022 was $11.8 million, or $0.14 net loss per share, compared to $20.0 million in the prior year period, or $0.29 net loss per share. The difference in net loss was primarily attributable to the recognition of the upfront payment in connection with the Company's licensing agreement with Theramex and lower research and development expenses, offset by higher general and administrative expenses.
