Geneva, Switzerland and Boston, MA - July 6, 2018 - ObsEva SA (NASDAQ: OBSV), a Swiss 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 announced the listing of its shares on SIX Swiss Exchange with the publication of its listing prospectus. ObsEva shares are expected to begin trading on the SIX Swiss Exchange on July 13, 2018, under the ticker symbol 'OBSN' under SIX's International Reporting Standard. ObsEva will not issue any new shares in connection with the listing in Switzerland.

The company is already listed on the NASDAQ Global Select Market (OBSV) since January 2017. The trading of ObsEva's shares on NASDAQ will continue in addition to the SIX listing. With listing on SIX Swiss Exchange, ObsEva is expecting to raise its profile among Swiss and European investors, provide another robust market for any future potential financing activities and to secure for its shareholders the protection offered by the Swiss takeover rules.

Ernest Loumaye, CEO and Co-Founder of ObsEva said: "Millions of women worldwide are affected by serious conditions compromising their reproductive health and pregnancy. At ObsEva, we believe the efficacy of the current standard of care is limited and associated with clear safety issues for women. The innovative solutions we are developing can potentially help resolve some of the major obstacles by offering orally active medications with fast onset therapeutic effect and fewer side effects. As a Swiss company, we are honoured to be listed on the SIX Swiss Exchange and to take another important step toward achieving our goals."

An innovative pipeline for significant unmet patient needs
There are millions of women globally of reproductive age (15 - 49) who suffer from reproductive health conditions that affect their quality of life, their ability to conceive, or that result in pregnancy  complications and newborn health issues. These women may require IVF to conceive, or they may be affected by conditions such as endometriosis, uterine fibroids and pre-term labor.

ObsEva is bringing innovative treatments to physicians and patients with the goal of improving upon the efficacy, tolerability and safety of existing therapeutic alternatives. Comprehensive preclinical and clinical development programs are in progress to confirm efficacy and safety of ObsEva's compounds.

Treatments in development include:

  • Linzagolix (OBE2109), a novel, oral GnRH receptor antagonist for the treatment of pelvic pain associated with endometriosis (200 million women affected) and heavy menstrual bleeding associated with uterine fibroids (80% of women develop the condition by age 50). In addition to treating the chronic symptoms of both conditions, treatment aims are to mitigate bone mineral density loss and other adverse effects associated with excessive estradiol suppression. Linzagolix is progressing well through clinical trials for the treatment of endometriosis and uterine fibroids. On June 18, 2018, ObsEva announced successful results for EDELWEISS, a Phase 2b clinical trial of linzagolix for the treatment of endometriosis related pelvic pain.
  • Nolasiban is an oral oxytocin receptor antagonist, to improve pregnancy and live birth rates in women undergoing IVF. IVF helps women achieve pregnancy through the collection of mature eggs in the ovaries, followed by fertilization and early embryo development in the laboratory before transfer of the embryos into the womb. A key focal point is improving IVF success utilizing single embryo transfer (SET), and avoiding transfer of multiple embryo transfers that lead to multiple pregnancies, and health risks associated with multiple births, including premature birth and low birth weight, in addition to much higher medical costs. ObsEva believes that Nolasiban could represent a compelling option for increasing IVF outcomes and resulting in pregnancy/live birth rate. In February 2018, the company released positive results from the Phase 3 IMPLANT2 clinical trial in Europe. Nolasiban improved the rate of ongoing 10-week pregnancy, and appears well tolerated with a safety profile not different from placebo.
  • OBE022 is an oral and selective prostaglandin receptor antagonist for treating preterm labor from 24 to 34 weeks gestational age. Preterm labor, defined as the body commencing the birthing process prior to 37 weeks, is characterized by uterine contractions, cervical dilation and rupture of the fetal membranes that surround and protect the fetus during pregnancy. Preterm labor can lead to preterm birth, which is currently the leading worldwide cause of death of newborn babies. To date, only treatments with limited efficacy or restrictive safety issues are available to treat preterm labor. OBE022 is designed to control preterm labor by reducing inflammation, decreasing uterine contractions and preventing cervical changes and fetal membrane ruptures. In December 2017, ObsEva announced the initiation of PROLONG, a Phase 2a proof-of-concept trial of OBE022 being conducted in Europe.  ObsEva plans to announce initial interim efficacy results from the PROLONG clinical trial in the fourth quarter of 2018.

Clear strategy going forward
ObsEva's strategy is to build the leading women's reproductive health and pregnancy company focused on conditions where current treatment options are limited and significant unmet needs exist. The key elements of the strategy include:

  • Continuing to advance each of the current product candidates in their respective indications.
  • Developing a targeted commercialization strategy for approved product candidates.
  • Pursuing additional indications for the current product candidates.
  • Leveraging the international product development experience and extensive network of clinical experts and pharmaceutical industry executives within women's reproductive health and pregnancy to in-license or acquire novel product candidates.
