Erlosiban (OBE-001 or Nolasiban) is an oral oxytocin receptor antagonist. Erlosiban inhibits myometrium contractions and inflammation elicited by oxytocin. Erlosiban has the potential to decrease contractions and improve uterine blood flow hence enhancing the receptivity of the endometrium to embryo implantation. This may increase the rates of successful implantation, clinical pregnancy, and live-births among patients undergoing ART, or more specifically IVF procedures.
