11:45 am MDT: “A Placebo-controlled, Randomized, Double Blind, Phase 3 Study Assessing Ongoing Pregnancy Rates After Single Oral Administration of a Novel Oxytocin Receptor Antagonist, Nolasiban, Prior to Single Embryo Transfer”

About the IMPLANT 2 Clinical Trial

IMPLANT 2 is a Phase 3, randomized, double blind, clinical trial designed to confirm the efficacy of nolasiban to increase the chance of pregnancy and live birth in patients undergoing IVF or ICSI. Following ovarian stimulation, egg retrieval and fertilization, eligible women were randomized to receive either a single, oral dose of 900 mg nolasiban or placebo, 4 hours before Day 3 or Day 5 fresh, single embryo transfer (SET). The primary endpoint was ongoing pregnancy at 10 weeks after SET. Women with confirmed pregnancies were monitored until delivery, with a key secondary endpoint being live birth, and the infants are being followed-up for 6 months.

About Assisted Reproductive Technology (ART)

Infertility affects about 10 % of reproductive-aged couples, with more than 2 million ART treatments (mostly IVF) performed worldwide each year. Currently 59% of fresh embryo transfers are performed on Day 5 and 31% on Day 3 in the United States (CDC report, 2015 data).

While the success of ART depends on multiple factors such as embryo response, fertilization, embryo quality and ET procedure, a successful pregnancy ultimately hinges on the receptivity of the uterus to accept embryo implantation. Uterine contractions at the time of ET, as well as suboptimal thickness of the uterine wall and reduced blood flow to the uterus, may impair the implantation of the embryo.

About Nolasiban

Nolasiban (previously known as OBE001), is an oral oxytocin receptor antagonist with the potential to decrease uterine contractions, improve uterine blood flow and enhance the receptivity of the endometrium to embryo implantation, all of which may increase the chance of successful pregnancy and live-birth among patients undergoing ART. ObsEva licensed nolasiban from Merck KGaA, Darmstadt, Germany, in 2013 and retains worldwide, exclusive, commercial rights.
