Premature Ovarian Insufficiency and Haematopoietic stem-cell transplantation (HSCT): what the trial registry contains

Why this is studied in Premature Ovarian Insufficiency

Primary ovarian insufficiency is loss of ovarian function before forty, from genetic, autoimmune or iatrogenic causes. Cell and platelet-based 'ovarian rejuvenation' aims to restore folliculogenesis. Occasional spontaneous ovulation occurs in this condition — including spontaneous pregnancies — which is the fact most often exploited by uncontrolled case reports.

What HSCT means in this table

Haematopoietic transplantation is the oldest and most consequential cell therapy in medicine, with conditioning regimens that carry real mortality risk alongside genuine disease-modifying power. Registrations under this label therefore mix decades-old standard-of-care protocols with newer autoimmune-reset trials, and the risk profile is nothing like that of an outpatient infusion.

The numbers

Every figure below comes from one reproducible query (primary ovarian insufficiency x hematopoietic stem cell transplantation) run against ClinicalTrials.gov API v2 on 2026-08-29.

How mature is this evidence?

A small later-stage tail exists (1 of 9 records at Phase 3 or 4); the centre of gravity is still Phase 1 and 2 work sized for safety rather than proof of benefit.

4 records are marked completed and 0 ended early (terminated, withdrawn or suspended): 0% of registrations did not run to plan.

Median planned enrolment is 51 participants (largest single study: 200). Trials of this size can describe safety and generate hypotheses; detecting a modest clinical benefit reliably usually needs substantially larger numbers with a control group.

Where the studies are

The work is distributed across 7 countries; Egypt alone accounts for about 33% of mentions, so 'internationally researched' can still mean concentrated in a few regulatory environments.

Legal pathway differs by country — see where cell therapy is legal, by country.

Who runs them

The sponsor mix is academic (4 academic or hospital, 3 commercial among the most frequent lead sponsors).

• Al-Azhar University — 2 records
• M.D. Anderson Cancer Center — 1 record
• University Hospital, Bordeaux — 1 record
• Instituto de Investigacion Sanitaria La Fe — 1 record
• First Affiliated Hospital Xi'an Jiaotong University — 1 record
• Stem Cells Arabia — 1 record

Representative registered studies

Recruiting studies first, then the most advanced phases. Each identifier links to the registry record, where eligibility criteria, outcome measures and contacts are published.

What this page does and does not tell you

These figures describe effort, not outcome. Published results, with their control arms and endpoints, are where benefit is decided.

If a clinic offers you this today, the useful question is not "is there research?" but "which of these registered studies is mine part of, and if none, what evidence applies to the exact product I am being sold?" The Provider Question Builder turns that into a scored checklist.

Frequently asked

How many HSCT studies for Premature Ovarian Insufficiency are recruiting right now?

0 of 9 registered records were listed as recruiting in the 2026-08-29 snapshot. Recruitment status changes frequently; the registry record is authoritative.

Is HSCT an approved treatment for Premature Ovarian Insufficiency?

Registration on ClinicalTrials.gov is not approval. Approval is granted by a regulator for a specific product and indication after review of submitted evidence. 9 registered studies tell you research exists, not that a product cleared review.

How advanced is the research on HSCT for Premature Ovarian Insufficiency?

1 of 9 records carry a Phase 3 or Phase 4 label and 4 are marked completed. Registrations run from 2002 to 2025.
