Enrolling by invitation

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

CAPA-IVM is being evaluated for its feasibility as an In vitro maturation (IVM) system in US fertility clinics. IVM is a laboratory process for maturing immature oocytes (eggs) outside of the body after egg retrieval. Egg retrievals are performed without prior ovarian stimulation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Signed Informed Consent Form to participate in this study voluntarily.
  2. Age 18-37 years at the time of starting the CAPA-IVM cycle.
  3. Body mass index (BMI) ≤38 kg/m2.
  4. Serum AMH levels greater than or equal to 3.5 ng/mL.
  5. Have an indication for IVM/IVF cycle.
  6. Have not received more than two previous treatments of IVM/IVF.
  7. Willing and able to comply with trial procedures, including oocyte pick-up from small follicles and to follow a CAPA-IVM cycle.
  8. Agree to culture all embryos to blastocyst stage, vitrify suitable blastocysts, and submit suitable blastocysts for PGT-A according to clinic protocol before determining transfer eligibility.
  9. Agree that only euploid CAPA-IVM-derived blastocysts will be eligible for transfer and that a single euploid blastocyst will be transferred per programmed FET cycle, unless a protocol-defined exception is prospectively justified by the investigator.

Exclusion Criteria:

  1. Prior ovarian surgery.
  2. Known uterine abnormalities (adenomyosis, leiomyoma (≥5 cm), bicornuate uterus, intrauterine adhesion) that would compromise successful pregnancy or live birth.

  12. Pregnancy or contraindication to pregnancy.
  13. Undiagnosed vaginal bleeding.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Metaphase II rate
Time Frame: Assessed approximately 40 hours after egg retrieval
The metaphase II (MII) rate is defined as the number of oocytes that reach MII stage of development divided by the number of cumulus-oocyte-complexes (COCs) placed into CAPA-IVM culture.
