Stem Cell Injection in Cancer Survivors

Phase 1
Completed
Conditions
Cardiomyopathy Due to Anthracyclines
Interventions
Biological: Placebo
Biological: Allo-MSCs
Registration Number
NCT02509156
Lead Sponsor
The University of Texas Health Science Center, Houston
Brief Summary

The primary purpose of this study is to examine the safety and feasibility of delivering allogeneic human mesenchymal stem cells (allo-MSCs) by transendocardial injection to cancer survivors with left ventricular (LV) dysfunction secondary to anthracycline-induced cardiomyopathy (AIC).

The secondary purpose of this study is to obtain preliminary evidence for therapeutic efficacy of allo-MSCs delivered by transendocardial injection to cancer survivors with LV dysfunction secondary to AIC.

Detailed Description

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.

Secondary Outcome Measures

Change in global circumferential strain as assessed via cardiac MRI

Change in left ventricular ejection fraction as assessed via cardiac MRI.

Change From Baseline in Left Ventricular Ejection Fraction (LVEF)-TrajectoryAssessed as a trajectory (baseline, 6 months, and 12 months)

The change in this measure over time is assessed using a repeated measures linear regression model of trajectory (change over time). If there is no interaction between change over time and treatment a single calculated value is the slope (the change per six months) from the model. If there is an interaction, the p-value for interaction is presented along with two calculated values representing the slope (the change per six months) for each treatment arm from the model.

Change in left ventricular end diastolic volume index as measured via cardiac MRI
