Phase II Clinical Trial to Evaluate the Ongoing Pregnancy Rate With OXO-001 in IVF/ICSI With Donor Oocytes.
- Registration Number
- NCT05076032
- Lead Sponsor
- OXOLIFE
- Brief Summary
The main objective of this clinical research trial is to test the efficacy of OXO-001 in a daily oral administration increasing the pregnancy rate in IVF/ICSI by preparing the uterus to receive the embryo.
- Detailed Description
Assisted reproductive techniques are the most common procedures to fulfill the desire for pregnancy in infertile women. Unfortunately, more than half of the assisted reproduction cycles result in implantation failure or early pregnancy loss, the two main causes of infertility and the most important unmet medical need in the field of infertility with current treatments.
This clinical trial aims to test the capacity of OXO-001 to enhance embryo implantation. It is a phase II, randomised, double-blind, parallel-group, placebo-controlled trial that will assess the ongoing pregnancy rate with OXO-001 (200 mg, 300 mg) or placebo at 10 weeks following fresh single blastocyst transfer resulting from donor oocyte IVF/ICSI.
