Acute Myocardial Infarction Clinical Trial
Official title:
A Retrospective Phase IIa Study of Intravenous Allogeneic Non-HLA-Matched, Unrelated Donor Stem Cell, MiSaver (Myocardial Infarction Saver), Infusion for Recent Acute Myocardial Infarction
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.
Cardiovascular diseases, particularly acute myocardial infarction (AMI), persist as significant health concerns despite advancements in pharmaceutical and interventional treatments. Herein,investigators hypothesized stem cells could enhance left ventricular functional outcomes in patients recently afflicted by acute myocardial infarction (AMI). To investigate this hypothesis, investigators initiated an open-label, dose-escalating trial to evaluate the safety and feasibility of intravenous infusion of ABO matched allogeneic umbilical cord blood stem cells (USC), prefabricated into our study product MiSaver (Myocardial Infarction Functional Saver), in patients following recent AMI. Participants were enrolled in cohorts of five, each receiving low or middle dosages (0.5x10^7 and 1.6x10^7 cells/kg, respectively), with infusions administered 2-5 days post-AMI onset. (Study details for low and middle dose please see study NCT04050163) Retrospective participants meeting similar inclusion criteria of recent AMI and LVEF < 45% were identified from the study site. Twenty eligible participants were selected as controls and compared for analysis with the low and middle dosage groups. ;
