Product Candidate for No Option Refractory Disabling Angina (NORDA)

NORDA is a severe end-stage condition which results in disabling symptoms due to extensive coronary disease that has not responded to bypass surgery, stenting or medications. OLOGO™ (CLBS14) has been studied in Phase 1, Phase 2 and Phase 3 randomized, double-blind placebo-controlled clinical trials. 1-3 Recent publications in the European Heart Journal4 and Cardiovascular Revascularization Medicine 5, 6, provide an independent analysis of the evidence from these studies and reveal significant improvements in exercise capacity, angina frequency and mortality in this orphan sized patient population. Under the terms of the RMAT designation, Caladrius is holding discussions with the FDA to determine the most expeditious regulatory pathway to bring this potentially restorative therapy to patients in need.
