Comparing a new semi-automated system for freezing eggs to the standard manual method

Paired Non-inferiority Study Comparing Overture Semi-automated Vitrification System ("DaVitri") to Standard Manual Process for Clinical Pregnancy Outcomes

Not applicable Interventional Overture Life · NCT06853418

This study is testing a new semi-automated system for freezing eggs to see if it works as well as the traditional manual method for women looking to preserve their fertility.

What this trial studies

This clinical trial aims to evaluate the effectiveness of the Overture Semi-automated Vitrification System, known as DaVitri, in comparison to the traditional manual process for oocyte cryopreservation. The study will recruit 260 female recipients and up to 130 donors, focusing on the clinical pregnancy outcomes associated with each method. Donors will provide informed consent and undergo egg retrieval, with their oocytes assessed for maturity and morphology before being randomly assigned to either the DaVitri or control group. The primary endpoint will be the blastocyst rate, which will help determine the non-inferiority of the new system.

Who should consider this trial

Good fit: Ideal candidates include premenopausal females aged 18-45 undergoing IVF with egg donation.

Not a fit: Patients over 45 years of age or those with certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the efficiency and outcomes of egg freezing procedures for patients undergoing IVF.

How similar studies have performed: Other studies have shown promising results with similar vitrification techniques, suggesting potential for success in this approach.
