A Phase 2 Trial of AMI MultiStem® Therapy in Subjects With Non-ST Elevation Acute Myocardial Infarction

A Phase 2 interventional study of AMI MultiStem cells and Sham in Heart Attack and NSTEMI, sponsored by Healios K.K.. Terminated at 11 sites in United States. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2021-07-22.

Registry
Myocardial Infarction — the first condition term the registry derived for this study.
ClinicalTrials.gg
Non-ST Elevated Myocardial Infarction
Why
  1. The study's listed conditions name Non-ST Elevated Myocardial Infarction, a narrower term within Myocardial Infarction.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Inclusion criteria

  • Subjects of either gender, 18-85 years of age, inclusive
  • Diagnosis of non-ST elevation myocardial infarction (NSTEMI)
  • (LVEF) between ≥ 25 and ≤ 45%

Exclusion criteria

Exclusion Criteria:

  • Previous Coronary Artery Bypass Graft (CABG)
  • Previous autologous, allogeneic bone marrow or peripheral stem cell transplant
  • Previous solid organ transplant
  • Anticipated need for additional planned coronary revascularization procedure(s)
  • Hemodynamic instability
  • Mechanical complications of the index acute myocardial infarction
Terms in these criteria, in plain language(1)

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.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

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 Jul 22, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
