Product Candidate for Coronary Microvascular Dysfunction (CMD)
CLBS16, the subject of a recently completed positive 20-patient proof-of-concept ESCaPE-CMD Phase 2 study at two centers in the United States. The trial was financially supported by a grant awarded from the National Heart, Lung and Blood Institute of the National Institutes of Health.
Coronary Microvascular DysfunctionCoronary microvascular dysfunction, previously known as Syndrome X, is a heart disease in which disease of the microcirculation results in severe myocardial ischemia in the absence of blockages in the large arteries. CLBS16 is designed to reduce the serious adverse consequences caused by the damage to the inner walls of the heart’s blood vessels through CD34+ cells’ innate ability to repair small blood vessels or microcirculation.
CD34+ cell therapy is supported by a profound body of clinical evidence
CD34+ cells have been investigated in clinical studies encompassing >700 patients
- Pre-clinical studies document improved microcirculation1
- Phase 2 clinical studies consistently show benefits in safety and function
- Reduced amputation in critical limb ischemia2
- Improved function in claudication3
- Reduced angina and improved ETT in refractory angina4
- Improved mortality and LVEF in dilated cardiomyopathy5
Opportunities exist across multiple under served cardiovascular indications
- Critical limb ischemia (CLI) in Japan
- Coronary microvascular dysfunction (CMD)
- Refractory angina
Phase 2 development program for coronary microvascular dysfunction
