Study summary

Ovarian Tissue Freezing For Fertility Preservation In Girls Facing A Fertility Threatening Medical Diagnosis Or Treatment Regimen

Read the detailed description

Cancer is a health concern; however, science advancement in disease detection and treatment modalities continues to improve patient survival rates. Cancer treatment consequences are gaining importance for survivors, families and providers. Infertility is a primary concern among female cancer survivors as it not only has biological implications, but psychosocial implications as well. Cancer treatment can cause acute ovarian failure, premature menopause and results in reproductive challenges in survivorship. Females who are approaching reproductive age at time of cancer diagnosis, who receive abdominopelvic radiation or high dose alkylating agents and those diagnosed with Hodgkin's lymphoma have increased risk for infertility following treatment. Cancer treatment is not the only treatment that threatens reproductive capacity, but rheumatoid arthritis and lupus treatment may also cause infertility.

Female cancer patients express fertility preservation is extremely important for their long-term psychosocial health. The current American Society for Clinical Oncology Clinical Practice Guideline states that all patients should be made aware of possible side effects of treatment on fertility, and that patients be offered fertility preservation interventions. Embryo banking or egg banking (oocyte preservation) prior to chemotherapy is the most successful options for fertility preservation in women. This option necessitates time for ovarian stimulation and retrieval which can take up to 2-3 weeks and is costly. This option may be longer for those who acquire ovarian hyper-stimulation syndrome and younger patients have a higher risk for OHSS. Embryo banking requires mature oocytes and can cause emotional and physical stress. The financial and physical challenges with fertility preservation motivate the desire to find alternatives for young cancer patients.

Improved freezing and thawing techniques for human oocytes have contributed to pregnancy rates comparable to those using fresh egg following in vitro fertilization. Prior to ovarian tissue cryopreservation there was no fertility preservation intervention available to patients who could not delay treatment or were too young to undergo hormonal stimulation. As of 2017, greater than 130 live births following transplantation of frozen/thawed ovarian tissue have been reported. Ovarian tissue cryopreservation has proven to be a safe and efficient method for preserving future fertility for patients undergoing potentially sterilizing treatments. Ovarian tissue cryopreservation is a standard-of-care in parts of Europe and is routine in several children's hospitals throughout the United States. We propose this option be available to qualifying patients at Phoenix Children's Hospital.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Newly diagnosed or with proposed treatment regimen containing at least ONE (1) of the following:

whole abdomen or pelvic irradiation

total body irradiation

Proposed treatment regimen to include any of the following:

cyclophosphamide equivalent dose (CED, see Green et al 2014) ≥7.5 g/m2

any treatment regimen containing procarbazine

bone marrow transplant conditioning regimen containing alkylators

OR health condition or malignancy that requires removal of one or both ovaries. Health status adequate to undergo elective laparoscopic surgery (as per anesthesiologist assessment)

Exclusion criteria

Exclusion Criteria:

  • Pregnancy or a patient who is currently breastfeeding

Patients who are eligible for and agree to oocyte preservation

Anyone deemed high risk for complications from the surgery and/or anesthesia.

Anyone unable to provide consent due to psychiatric conditions or cognitive delay (in parent/guardian for patients \<18 years, and patient >18 years)

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

    Procedure: Ovarian tissue removal will be performed laparoscopically

Interventions

  • ProcedureOvarian tissue removal will be performed laparoscopically

    under general anesthesia concomitantly with another scheduled procedure if possible. Following removal, ovarian tissue will be shipped to University of Pittsburg Medical Center, Magee-Womens Research Institute for processing. Freezing and storing techniques will be in accordance with FDA regulations for reproductive tissues, guidelines of the American Association of Tissues Banks and any other applicable federal, state and local regulations. The tissue will be carefully separated dividing the cortex from the medulla. The cortex will then be cryopreserved for long term storage. The medulla will be shipped overnight back to the PCH Department of Pathology for histological evaluation. If pathology finds evidence of cancer in the ovarian tissue provided, they may request that all of the patient's tissue be returned to pathology for a more detailed examination, which may eliminate the tissue available for the patient's future use.

What researchers measure

Primary outcomes

  1. Percentage of patients who utilize their ovarian tissue and the age at which they use it will be evaluated. The number of patients who elect to have OTC will be analyzed over time to identify trends.

    data will be investigated via qualitative analysis.

    Time frame: 10 years

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2020 (actual). Primary completion is estimated for Jul 2030, 120 months after the start.

Of 141 non-industry interventional studies with no phase under Infertility, Female, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 41. This study's planned 120 months is above that.

Counting every sponsor, half of 155 studies reached it within 23 months; a quarter within 9 and three quarters within 41.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
