Safety evaluation of Intra-Coronary Administration of MCRcI® stem cells in Patients with Diffuse Coronary Artery Disease.

This trial is a Phase II, multicenter clinical study. The purpose of this trial is to evaluate the safety and efficacy of MiSaver, a cellular therapy product, in patients who have experienced an acute myocardial infarction (AMI). Specifically, the study aims to assess the improvement in left ventricular function of the heart following the administration of MiSaver, as well as to determine the safety of using stem cell therapy in these patients.
This trial will employ a single-blind design (subject-blinded), meaning that the participants will not be aware of whether they are receiving MiSaver or standard treatment, while the researchers will have this information. This design helps ensure transparency and adherence to ethical standards while also providing valuable clinical insights.
By utilizing randomization, we can enhance the reliability and comparability of the study results. A portion of the participants will receive MiSaver, while the others will undergo standard treatment. This allows for a direct comparison of the two therapeutic approaches to determine their respective efficacy.
The primary objective of this trial is to evaluate the safety and efficacy of MiSaver, in the treatment of patients with acute myocardial infarction (AMI). To achieve this, we will collect comprehensive participant data, including assessments of cardiac function, records of cardiac events, and quality-of-life surveys. By analyzing these data, we aim to gain a deeper understanding of the benefits and limitations of this treatment approach.

Despite advancements in treatments, cardiovascular diseases, especially acute myocardial infarction (AMI), remain significant health concerns. This study hypothesized that stem cells could improve left ventricular function post-AMI. An open-label trial was initiated to assess the safety and feasibility of intravenous infusion of ABO blood group-matched allogeneic umbilical cord blood stem cells (USC) prefabricated into MiSaver (Myocardial Infarction Saver) in AMI patients.
Primary Endpoint:
The primary endpoint focused on safety and adverse events over a 12-month observational period. Results showed the treatment was well-tolerated with no AEs attributed to the study product.
Secondary Outcomes:
Secondary outcomes evaluated changes in left ventricular ejection fraction (LVEF) from baseline to 12 months post-treatment. A retrospective study compared eligible controls with low and middle dosage groups.
