  • Child, Adult

Who may be able to join

  • Female Patients only
  • 0-42 years of age.
  • Will undergo surgery, chemotherapy, drug treatment and/or radiation for the treatment or prevention of a medical condition or malignancy that places the patient at risk for impaired ovarian function and infertility OR, have a medical condition or malignancy that requires removal of all or part of one or both ovaries.
  • May have newly diagnosed or recurrent disease. Those not enrolled at the time of initial diagnosis are eligible if they have not received therapy that is viewed as likely to result in complete and permanent loss of ovarian function.

About this study

Official title: Ovarian Tissue Cryopreservation for Fertility Preservation in Girls and Women Facing a Fertility Threatening Medical Diagnosis or Treatment Regimen

This study will compare efficacy of ovarian tissue freezing using slow-freeze versus vitrification methods.

Read the detailed description

The primary objective of this study is to determine the efficacy of ovarian tissue cryopreservation using slow-freeze and vitrification methods in enabling long-term preservation of ovarian function and fertility, in females undergoing treatment that may cause infertility. This study will provide study participants with their own tissue to cryopreserve and reserve for future use and:

  • Determine the efficacy of ovarian cryopreservation techniques.
  • Provide long-term follow up for patients who have undergone ovarian tissue cryopreservation for participants' own use.

In addition to providing study participants with the future opportunity to use their tissue with the intent to reinstate ovarian function, this study will provide research tissue to the embryology research lab at the Family Fertility Center at Texas Children's Hospital that will be used to:

  • Optimize techniques for ovarian tissue cryopreservation of ovarian tissue for use in future retransplantation).
  • Investigate factors affecting successful maturation and quality of immature oocytes obtained from ovarian tissue including growth factors, hormones and other culture conditions.

What participants receive

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

  • OophorectomyProcedure or surgery

    Patients undergoing surgery for any indicated procedure for fertility-threatening treatment will have attempt at collecting ovarian tissue at time of surgery.

Study groups in NCT05434936
Study groupRoleWhat they receive
CollectionOtherThere is only one arm of the study, all patients enrolled will have surgery in which the attempt will be made to collect ovarian tissue.
Receives: Procedure: Oophorectomy

What is being measured

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

  1. Effect of vitrification and slow freeze cryopreservation methods on follicular survival

    Investigators will explore and compare the impact of vitrification and slow freeze cryopreservation methods by evaluating follicular survival using classic histological analysis of follicular morphology.

    Measured: 5+ years

Secondary outcomes (1)
  1. Live birth rates in patients using cryopreserved ovarian tissue

    Investigators will explore reproductive outcomes of women using cryopreserved tissue by measuring the live birth rate as defined by the number of initial live births divided by the total number of ovarian tissue implantations performed.

    Measured: 5+ years

Model description
This is a tissue bank protocol in which prospectively collected specimens of ovarian tissue and a sample of whole blood will be obtained from patients who elective to cryopreserve ovarian tissue to preserve fertility. The portion of tissue designated for patient use will be cryopreserved using the slow freeze method while the portion designated for research purposed will be divided and cryopreserved using the slow freeze versus vitrification methods.

Questions about this trial

What is this clinical trial studying?

A study testing Oophorectomy in people with Fertility Preservation, run by Baylor College of Medicine at 1 site in United States.

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 5 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: paused, as of the sponsor's last update on 18 Jun 2023. 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 United States. 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?

Results are not available in the source record.

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?

Effect of vitrification and slow freeze cryopreservation methods on follicular survival (time frame: 5+ years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jun 2023.
