About

The primary objective of this study is to determine whether transendocardial delivery of allogeneic human bone marrow-derived mesenchymal precursor cells (MPCs [rexlemestrocel-L]) is effective in the treatment of chronic heart failure (HF) due to left ventricular (LV) systolic dysfunction.

Full description

The purpose of this study is to evaluate the efficacy and safety of a single transendocardial delivery in the cardiac catheterization laboratory of human bone marrow-derived allogeneic MPCs (rexlemestrocel-L) for improvement in clinical outcomes (heart failure major adverse cardiac events [HF-MACE]), preventing further adverse cardiac remodeling (left ventricular end systolic volume [LVESV] and left ventricular end-diastolic volume [LVEDV]), and increasing exercise capacity (six-minute walking test [6MWT]) in participants with chronic HF due to LV systolic dysfunction of either ischemic or nonischemic etiology who have received optimal medical/revascularization therapy.

Enrollment: 565 patients

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• The participant is 18 to 80 years of age, inclusive; both men and women will be enrolled.
• The participant has a diagnosis of chronic HF of ischemic or nonischemic etiology for at least 6 months
• The participant is on stable, optimally tolerated dosages of HF therapies including beta-blockers (approved for country-specific usage), angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs), and/or aldosterone antagonists, without change in dose for at least 1 month before study intervention
• The participant is on a stable, outpatient, oral diuretic dosing regimen in which the participant remains clinically stable during screening.
• Other Criteria apply, please contact the investigator

Exclusion criteria

• The participant has NYHA Functional Class I or Functional Class IV symptoms.
• Other Criteria apply, please contact the investigator

565 participants in 2 patient groups

Sham Control

Sham Comparator group

Description:

Participants randomly assigned to control treatment underwent a single cardiac catheterization involving a scripted sham cardiac mapping and cell delivery procedure at a cell injection center at Day 0 by an interventional cardiology team not involved with review or assessment of subsequent study results.

Experimental group

Description:

Participants randomly assigned to treatment underwent a single index cardiac catheterization involving transendocardial delivery of rexlemestrocel-L into the myocardium at a cell injection center at Day 0 by an interventional cardiology team not involved with review or assessment of subsequent study results.
