Trial Summary

Will I have to stop taking my current medications?

The trial requires participants to be on stable, maximally tolerated doses of heart failure medications for at least one month before joining. This means you should not stop taking your current medications, but they need to be stable without changes for 30 days.

What data supports the effectiveness of the treatment Umbilical Cord-derived Mesenchymal Stromal Cells (UC-MSCs) for cardiomyopathy?

Research shows that UC-MSCs can improve heart function and repair heart tissue in animal models of heart disease, suggesting they might help in treating cardiomyopathy. These cells have been shown to improve heart function in rat models of heart failure and have regenerative potential in heart conditions.12345

Is stem cell therapy using umbilical cord-derived mesenchymal stromal cells (UC-MSCs) safe for humans?

Studies have shown that using umbilical cord-derived mesenchymal stromal cells (UC-MSCs) in humans is generally safe, with no serious adverse effects reported in patients with heart failure or rheumatoid arthritis.15678

How is the treatment with Umbilical Cord-derived Mesenchymal Stromal Cells (UC-MSCs) different from other treatments for cardiomyopathy?

This treatment is unique because it uses stem cells from umbilical cords, which are easily accessible and can be expanded in the lab. Unlike other treatments, UC-MSCs are administered intravenously and have shown potential to improve heart function by helping repair heart tissue in experimental models.12359

What is the purpose of this trial?

This is a Phase IIA, randomized, double blind, placebo controlled, multicenter study designed to assess the safety, feasibility, and efficacy of umbilical cord derived mesenchymal stromal cells (UC MSCs), administered intravenously (IV) as a single dose or repeated doses, in patients with ischemic cardiomyopathy (ICM).

Treatment Details

Interventions

  • Umbilical Cord-derived Mesenchymal Stromal Cells (UC-MSCs)
Trial Overview The trial is testing whether injecting umbilical cord-derived mesenchymal stromal cells into patients with ischemic cardiomyopathy can be safe and effective. Participants will receive either one dose or repeated doses intravenously in a randomized double-blind setup against a placebo.
Participant Groups
3Treatment groups
Experimental Treatment
Placebo Group
Group I: single-dose groupExperimental Treatment1 Intervention
One dose of UC-MSCs (100 x 106 cells) will be infused IV at a rate of 2 ml/min for a total of 60 ml over 30 minutes (3.3 million cells/ml/min). This will be followed by three IV infusions of placebo (same volume and rate) 2, 4, and 6 months later.
Group II: repeated-dose groupExperimental Treatment1 Intervention
Four doses of UC-MSCs (100 x 106 cells each) will be given 2 months apart. Each dose will be infused IV at a rate of 2 ml/min for a total of 60 ml over 30 minutes (3.3 million cells/ml/min).
Group III: control groupPlacebo Group1 Intervention
Four doses of vehicle (Plasma-Lyte A supplemented with 1% HSA) will be given 2 months apart. Each dose will be infused IV at a rate of 2 ml/min for a total of 60 ml over 30 minutes.

Findings from Research

Transplanting human umbilical cord-derived mesenchymal stem cell (UC-MSC) sheets onto the heart significantly improved cardiac function in rat models of chronic ischemic heart failure compared to control groups, as shown by echocardiography after four weeks.
The UC-MSC sheets not only enhanced heart function but also reduced left ventricular remodeling and improved neovascularization, indicating their potential as an effective treatment strategy for heart disease.
Human umbilical cord-derived stem cell sheets improve left ventricular function in rat models of ischemic heart failure.Wu, Y., Zhang, H., Wang, S., et al.[2022]
Transplanting human umbilical cord-derived mesenchymal stromal cells (hUC-MSCs) into the heart after a myocardial infarction in rats significantly improved heart function, as shown by a better left ventricular ejection fraction compared to the control group.
The hUC-MSCs not only engrafted into the heart tissue but also partially transformed into heart muscle cells (cardiomyocytes) and promoted new blood vessel formation, indicating their potential for enhancing heart regeneration after injury.
Umbilical cord mesenchymal stromal cells engraft and transdifferentiate into cardiomyocyte-like cells following acute myocardial ischemia⋆.Yigman, Z., Ozdemir, ED., Turan, NN., et al.[2021]
In a rat model of myocardial infarction, chorion-derived mesenchymal stem cells (C-MSCs) significantly improved heart function, as indicated by increased left ventricular ejection fraction (LVEF) and fractional shortening (FS) after 8 weeks compared to control and other stem cell types.
C-MSCs also enhanced capillary density and showed higher expression of cardiac markers (cTnT and α-SA), suggesting they have superior therapeutic potential for heart repair compared to bone marrow-derived (BM-MSCs) and umbilical cord-derived mesenchymal stem cells (UC-MSCs).
