About this study

Official title: Autologous Stem Cell Ovarian Transplantation to Restore Ovarian Function in Premature Ovarian Failure Patients. Pilot Study ASCOT-2

This study aims to recover ovarian function in POF/POI patients. With this pueprose we designed a study protocol including two arms: ASCOT arm, were patients receive the stem cell mobilization treatment with Granulocyte colony stimulating factor (G-CSF) followed by apheresis and ovarian artery catheterism to selectively infuse the stem cells into the ovary and the G-CSF arm including patients that receive the mobilization treatment but not the ovarian artery catheterism to selectively infuse the cells into the ovary.

Read the detailed description

Ovarian aging appears early in life as a decline in function at 30s leading to a complete ovarian failure around 51 years of age in women. Women in modern society have delayed the age of childbearing due to socioeconomic changes and patient´s age has become the main determinant of infertility, since it is well known that both quantity and quality of the oocytes from aging patients are seriously impaired. Nevertheless, the low ovarian reserve is not only associated with age. Primary ovarian insufficiency (POI) is a cause of infertility in women, affecting 1% of the population. It is characterized by amenorrhea, hypoestrogenism, and elevated gonadotropin levels in women younger than 40 years of age. Impairment of ovarian function in POI can be mixed up with a low ovarian reserve or poor ovarian response although represent different clinical entities and patients.

Thus, interventions to recover damaged gonads in POI patients should be developed in order to enhance their reproductive potential. Clinically, bone marrow (BM) transplant in patients with POI due to chemotherapy treatment rescues ovarian functions as demonstrated by several spontaneous pregnancies. Previous research demonstrates that autologous stem cell ovarian transplantation (ASCOT) improves ovarian reserve (AMH and AFC) in 81% of women. Three of the eleven included patients achieve 5 pregnancies and 3 healthy babies have born. Response is highly variable between patients and molecular mechanisms still unknown. New approach is mandatory to elucidate them.

Results obtained in our premature ovarian failure (POF) animal model (included chemotherapy, CT ovarian injury) demonstrate that bone marrow stem cells restore ovulation by means of increasing vascularization, proliferation and diminishing apoptosis within the ovarian niche. These ovarian niche improvements promotes follicular development, increased number of antral and preovulatory follicles and corpus luteum.

POF model is ideal to demonstrate effectivity of ASCOT technique as they represent the worst possible scene. Any improvement in those patients should be significant.

Trying to be less invasive, we designed a study protocol including two arms: ASCOT arm as previously described and Granulocyte colony stimulating factor (G-CSF) arm including patients that receive the treatment but not the apheresis nor the ovarian artery catheterism to selectively infuse the cells into the ovary.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing G-CSF and ASCOT in people with Premature Ovarian Failure (POF), run by Instituto de Investigacion Sanitaria La Fe at 1 site in Spain.

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 4 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 24 May 2018. 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 Spain. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact Monica Romeu, Doctor (+34961244000 ext. 244116, monicaromeuvillarroya@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Antral follicle count (AFC) (time frame: 6 months). 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 24 May 2018.
