Stem Cell Injection in Cancer Survivors

This phase I, randomized, placebo-controlled, trial will evaluate the safety and feasibility of allo-MSCs administered by transendocardial injection in thirty-seven subjects with anthracycline-induced cardiomyopathy (AIC). The first six subjects received allo-MSC therapy (open label) and were assessed for safety and feasibility of the study procedures. Following 1 month data review of each of the six subjects by the National Heart, Lung, and Blood Institute Gene and Cell Therapy Data Safety Monitoring Board; this was followed by a randomized, double-blind clinical trial enrolling thirty-one subjects. These subjects were randomized 1:1 to receive allo-MSCs or placebo. All subjects underwent cardiac catheterization and study product administration using the NOGA Myostar catheter injection system. Subjects are being followed at 1 day, 1 week, 1 month, 6 months, and 12 months post study product injection. All endpoints are assessed at the 6 and 12 month visits which will occur 180 ±30 days and 365 ±30 days, respectively, after the day of study product injection (Day 0). For the purpose of the safety evaluations and endpoint analysis, the Investigators will utilize an "intention-to-treat" study population. In addition, because this phase I study is the first cell therapy study in this population, at 12 months available standard-of-care medical records for cancer surveillance will be reviewed for cancer recurrence.
