Geneva, Switzerland and Boston, MA - March 9, 2018 - ObsEva SA (NASDAQ: OBSV), 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 fourth quarter and year ended December 31,2017, and provided a business update outlining recent corporate progress and upcoming milestones.

"2017 was a very important year for ObsEva as we became a public company, focused on designing, initiating, and enrolling clinical trials within our four ongoing development programs seeking to bring new treatment alternatives to women in need" said Ernest Loumaye, co-founder and Chief Executive Officer of ObsEva. "We look forward to delivering on our strategic, clinical and regulatory milestones for all three of our development compounds over the course of 2018".  

Recent Pipeline Highlights

  • Randomization of 778 patients was completed in the fourth quarter of 2017 for the Phase 3 IMPLANT 2 trial of nolasiban, ObsEva's oral oxytocin receptor antagonist given as a single dose, 4 hours prior to a single ET and designed to improve clinical pregnancy and live birth rates in women undergoing in-vitro fertilization (IVF).  Positive top line results disclosed in February 2018 showed the primary endpoint was achieved, with a 10-week ongoing pregnancy rate of 35.6% for nolasiban treated patients vs. 28.5% for placebo treated patients, a 25% relative increase (p= 0.031).  In the embryo transfer (ET) D5 subgroup, the relative increase was 32% and the absolute increase was 11.2% in favor of nolasiban (nolasiban 45.9% and placebo 34.7%, p = 0.034). In addition, nolasiban treatment was safe and well tolerated with no difference in rates of discontinuation from treatment emergent adverse events (TEAE's) nor the incidence of serious adverse events (SAE's) as compared to placebo. 
  • U.S. patient recruitment was completed in the fourth quarter of 2017 for the EDELWEISS Phase 2b clinical trial of OBE2109, ObsEva's oral GnRH receptor antagonist for the treatment of endometriosis.  Enrollment in the trial of approximately 330 patients combined in Europe and the U.S. is now complete, and the patient treatment and follow-up portion of the trial is ongoing.  
  • Patient enrollment continued in the PRIMROSE 1 and PRIMROSE 2 Phase 3 clinical trials of OBE2109 for the treatment of uterine fibroids, with a target enrollment of approximately 1,000 women in total (US and Europe).
  • The PROLONG Phase 2a clinical trial of OBE022, ObsEva's oral prostaglandin F2 alpha receptor antagonist for the treatment of pre-term labor in pregnant women between 24 and 34 weeks of gestation, was initiated in December, 2017.

Upcoming Milestones

ObsEva expects to achieve the following clinical and regulatory milestones during 2018:

  • 12 week results from the Phase 2b EDELWEISS clinical trial of OBE2109 for the treatment of endometriosis, in mid-2018.  End-of-phase 2 meeting with regulatory authorities to discuss the design of the phase 3 program for that indication is expected by the end of 2018.
  • Completion of patient recruitment in the Phase 3 PRIMROSE 1 and 2 trials of OBE2109 for the treatment of uterine fibroids by the end of 2018.
  • Results of live birth rates and 28-day neonatal safety from the Phase 3 IMPLANT2 clinical trial of nolasiban in IVF in the fourth quarter of 2018. Post consultation with regulatory authorities, initiation of US Phase 3 clinical development program is expected by the end of 2018.  
  • Initial efficacy results from the Phase 2a PROLONG clinical trial of OBE022 in pre-term labor in late 2018.
