About this study

Official title: Auto-transplantation of Fragmented Ovarian Cortical Tissue in Infertile Patients With Premature Ovarian Oocyte Depletion - a Study to Promote Follicular Activation and Subsequent Fertility

The aim of this project is to activate recruitment and growth of resting primordial follicles in the ovaries of women with diminished ovarian reserve, in attempt to increase the chance to become pregnant, either naturally or after assisted reproduction.

Read the detailed description

For this study investigators will carefully select 20 women with low AMH and imminent POI.

They will be randomized to have cortical ovarian biopsies taken from either the left or right ovary. The biopsies will be fragmented in 1x1 mm2 pieces and immediately auto-transplanted in a peritoneal pocket under the right ovary.

The contralateral untouched ovary will act as the control, making each woman their own control.

Follow up: each week in 2,5 months the women will be assessed by transvaginal ultrasound and hormonal status. After 2,5-6 months the women will receive a FSH stimulation cycle (rFSH 300 IU or Corifollitropin) followed by standard IVF/ICSI,

Hypothesis: the ovaries contain a pool of resting primordial follicles. By fragmentation of cortical ovarian tissue, manipulation of the local environment in the tissue will inhibit the Hippo Pathway and hereby active recruitment and growth of primordial follicles.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Biopsy of ovarian cortical tissueProcedure or surgery

    Biopsies will be taken from either right or left side. The cortical tissue will be isolated and fragmented in 1x1 mm2 pieces, followed by auto-transplantation to a peritoneal pocket.

Receives: Procedure: Biopsy of ovarian cortical tissue

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of follicles > 12 mm

    Number of follicles > 12 mm in response to controlled ovarian stimulation with corifollitropin from the biopsied ovary versus the contralateral untreated ovary

    Measured: Up to 6 month after the auto-transplantation

Secondary outcomes (1)
  1. Side of ovulation

    Frequency of ovulations occurring at the "biopsy side" versus the contralateral side in the subsequent 4- 6 months

    Measured: Up to 6 months after auto-transplantation

Questions about this trial

What is this clinical trial studying?

A study testing Biopsy of ovarian cortical tissue in people with Infertility, run by Anders Nyboe Andersen at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of follicles > 12 mm (time frame: Up to 6 month after the auto-transplantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02792569, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2020.
