Cell therapy for chronic heart pain

Randomized Controlled Pivotal Trial of Autologous Bone Marrow Cells Using the CardiAMP Cell Therapy System in Patients With Refractory Angina Pectoris and Chronic Myocardial Ischemia (CardiAMP CMI Trial)

Not applicable Interventional BioCardia, Inc. · NCT03455725

This study tests whether a new cell therapy can help people with chronic heart pain feel better and improve their heart function compared to a placebo treatment.

What this trial studies

This trial evaluates the effectiveness of the CardiAMP cell therapy system in treating patients with refractory angina and chronic myocardial ischemia. It is a multi-center, randomized, sham-controlled, and double-blinded study comparing the actual treatment with a sham procedure. Participants will receive either the active bone marrow cell therapy or a placebo treatment, with the aim of assessing improvements in angina symptoms and overall heart function.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 to 80 with severe refractory angina who have not responded to maximum doses of anti-angina medications.

Not a fit: Patients with other significant cardiac or vascular conditions or those who do not meet the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly reduce angina symptoms and improve quality of life for patients with chronic heart pain.

How similar studies have performed: Other studies using stem cell therapies for heart conditions have shown promise, suggesting potential for success in this approach.
