Heart Failure & Cardiac Repair and Haematopoietic stem-cell transplantation (HSCT): what the trial registry contains
The ClinicalTrials.gov registry holds 13 records for HSCT in Heart Failure & Cardiac Repair: 1 recruiting now, 1 labelled Phase 3 or 4, across 14 countries. Snapshot 2026-08-29.
Why this is studied in Heart Failure & Cardiac Repair
Heart failure with reduced ejection fraction involves lost cardiomyocytes and adverse remodelling. Cell therapy has been studied here longer than in almost any other indication, and the arc is instructive: early enthusiasm, mixed later-phase results, and a field that has narrowed its claims from regeneration to modest functional support.
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 (heart failure x hematopoietic stem cell transplantation) run against ClinicalTrials.gov API v2 on 2026-08-29.
| Metric | Value |
|---|---|
| Registered studies (all statuses) | 13 |
| Interventional studies in the sample | 12 |
| Recruiting right now | 1 |
| Completed | 6 |
| Terminated, withdrawn or suspended | 2 |
| Phase 3 or Phase 4 records | 1 |
| Countries with at least one site | 14 |
| Median planned enrolment | 40 participants |
| Largest single planned enrolment | 159 participants |
| First / most recent start year | 2006 — 2020 |
How mature is this evidence?
The ladder is partly climbed: 1 confirmatory-phase records against 13 in total, with the remainder concentrated in dose-finding and safety territory.
6 records are marked completed and 2 ended early (terminated, withdrawn or suspended): 15% of registrations did not run to plan.
| Phase label | Records | Share |
|---|---|---|
| Phase 2 | 8 | 50% |
| Phase 1 | 6 | 38% |
| Phase 3 | 1 | 6% |
| Not applicable | 1 | 6% |
Median planned enrolment is 40 participants (largest single study: 159). 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
Across 14 countries with registered sites, United States dominates at roughly 35% — a concentration driven by funding and regulation rather than by clinical outcome.
| Country | Studies with a site there |
|---|---|
| United States | 6 |
| Canada | 2 |
| Iran | 2 |
| China | 1 |
| Japan | 1 |
| Australia | 1 |
| Austria | 1 |
| Belgium | 1 |
| France | 1 |
| Italy | 1 |

What this page does and does not tell you
Registration counts measure activity, not effect. A study appears here the moment it is registered — before any participant is enrolled, and regardless of whether results are ever posted.
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 Heart Failure & Cardiac Repair are recruiting right now?
1 of 13 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 Heart Failure & Cardiac Repair?
Registration on ClinicalTrials.gov is not approval. Approval is granted by a regulator for a specific product and indication after review of submitted evidence. 13 registered studies tell you research exists, not that a product cleared review.
How advanced is the research on HSCT for Heart Failure & Cardiac Repair?
1 of 13 records carry a Phase 3 or Phase 4 label and 6 are marked completed. Registrations run from 2006 to 2020.
