Allogeneic Mesenchymal Human Stem Cell Infusion Therapy for Endothelial DySfunctiOn in Diabetic Subjects With Symptomatic Ischemic Heart Disease. (ACESO-IHD) (ACESO-IHD)

June 15, 2026 updated by: Joshua M Hare

Allogeneic Mesenchymal Human Stem Cell Infusion Therapy for Endothelial DySfunctiOn in Diabetic Subjects With Symptomatic Ischemic Heart Disease.

The purpose of this study is to test the hypothesis that allogeneic Mesenchymal Stem Cells (MSCs) promote systemic and coronary endothelial repair through rescue of bone marrow progenitors in type 2 diabetic patients with symptomatic IHD compared to placebo.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
