Regression of Fibrosis & Reversal of Diastolic Dysfunction in HFpEF Patients Treated With Allogeneic CDCs

Summary

Perform a randomized, double blind, placebo-controlled Phase 2a feasibility study to determine whether treatment of HFpEF patients with intracoronary allogeneic CDCs affects clinical functional status (QOL scores), exercise tolerance (6MHW), exercise hemodynamics (supine exercise ergometry during right heart catheterization), myocardial interstitial fibrosis (MRI with native T1 mapping and calculation of extracellular volume \[ECV\] after gadolinium administration), macroscopic fibrosis by delayed gadolinium enhancement (DGE), and diastolic function (catheterization, echocardiography, BNP). Treatment of patients with symptomatic hypertensive heart disease-induced HFpEF with allogeneic CDCs will be safe and will improve clinical functional status, exercise tolerance/hemodynamics, myocardial interstitial structure, and diastolic function; the mechanisms underlying these improvements will be reflected in changes in plasma biomarkers that indicate a reduction in pro-inflammatory and pro-fibrotic signaling.
