Geneva, Switzerland and Boston, MA – March 5, 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 fourth quarter and the year ending December 31, 2018. It has also provided a business update outlining recent corporate progress and upcoming milestones.
“2018 was a year of tremendous pipeline advancement with successful clinical data readouts that have positioned ObsEva to take the next step in 2019 towards the transition to a commercial company,” said Ernest Loumaye, co-founder and Chief Executive Officer of ObsEva. “We are looking forward to Phase 3 data this year for both nolasiban and linzagolix, followed by our first regulatory filing planned for Europe.”
- In November 2018, ObsEva announced the initiation of the Phase 3 IMPLANT4 trial of the oxytocin receptor antagonist nolasiban in IVF. IMPLANT4 is planning to enroll approximately 820 patients undergoing a Day 5 single embryo transfer (SET) at approximately 50 clinical sites in 10 countries primarily in Europe (n=41), Canada (n=4) and Russia (n=4).
- In December 2018, patient recruitment was completed in the Phase 3 PRIMROSE 2 trial of the oral GnRH receptor antagonist linzagolix for the treatment of uterine fibroids. Along with the PRIMROSE 1 trial in the U.S., these trials are targeting enrollment of approximately 1,000 women and are designed to assess the effect of the linzagolix treatment on heavy menstrual bleeding (HMB) associated with uterine fibroids. The efficacy and safety of two linzagolix doses being studied are 100mg without ABT and 200mg with ABT.
- Also during the quarter, ObsEva completed a successful end-of-Phase 2 meeting with the FDA to review the Phase 3 clinical trial program for linzagolix in endometriosis, which is commencing this quarter. The EDELWEISS 2 and 3 trials are expected to enroll approximately 900 patients in total with endometriosis associated pain, comparing two, once-daily, dosing regimens of linzagolix to placebo; 75mg without ABT, and 200mg with ABT.
- In early 2019, ObsEva announced the completion of the open label Part A of the PROLONG Phase 2a trial of the oral prostaglandin F2 alpha receptor antagonist OBE022, for the treatment of pre-term labor in pregnant women between 24 and 34 weeks of gestation. The randomized, double-blinded, placebo-controlled Part B of the trial is presently enrolling patients after observing 8 of 9 patients successfully completing the 7-day dosing period without delivering a baby, as well as a positive pharmacokinetic (PK) and safety data.
ObsEva expects to achieve the following clinical and regulatory milestones in 2019:
- In the second quarter of 2019, results for the final prospectively designed endpoint are expected from the IMPLANT2 trial of nolasiban, which is the 6-month pediatric safety follow-up.
- In the first half of 2019, the Week 48 (6-month post treatment follow-up) and the Week 52 (treatment extension up to 12 months) results in the EDELWEISS phase 2b trial.
- In the second quarter of 2019, ObsEva expects to announce completion of patient recruitment in the IMPLANT 4 trial of nolasiban with expected primary endpoint, 10-week ongoing pregnancy results expected in the fourth quarter of 2019. Assuming confirmatory results, a European Marketing Authorization Application (MAA) regulatory submission is planned for late 2019.
- For U.S. nolasiban development, additional FDA feedback on trial design is expected in the second quarter of 2019, which may lead to commencement of the Phase 3 program in the second half of 2019.
- Six-month primary endpoint data from the PRIMROSE 2 trial of linzagolix for the treatment of uterine fibroids is expected in the fourth quarter of 2019, and recruitment completion for the PRIMROSE 1 trial is now expected in the second quarter of 2019 with primary endpoint data anticipated in early 2020. Accordingly, an NDA for linzagolix in uterine fibroids remains targeted for 2020.
- Part B of the Phase 2a PROLONG clinical trial of OBE022 in acute pre-term labor is presently ongoing, with initial interim analysis of the primary endpoint for the first 30 patients expected by H1:19.
