Caladrius Biosciences Treats First Patient in the Phase 2b FREEDOM Trial of CLBS16 for the Treatment of Coronary Microvascular Dysfunction

Initiation of the Phase 2b FREEDOM trial represents the next step in development of CLBS16 as a potential breakthrough treatment for the millions of sufferers of CMD in the U.S., most of whom are women

Patient enrollment underway at The Christ Hospital Health Network in Cincinnati (OH) and Mayo Clinic in Rochester (MN) with additional sites across the United States targeted to open soon

Strong investigator and subject interest driven by the positive results of the Phase 2a ESCaPE-CMD trial reported in spring of 2020

BASKING RIDGE, NJ, USA I January 19, 2021 I Caladrius Biosciences, Inc. (Nasdaq: CLBS) (“Caladrius” or the “Company”), a clinical-stage biopharmaceutical company dedicated to the development of cellular therapies designed to reverse disease, announced that it has treated the first patient in its Phase 2b FREEDOM trial of CLBS16 as a therapy for coronary microvascular dysfunction (“CMD”) at The Christ Hospital Health Network in Cincinnati, Ohio. The 105-patient double-blind and placebo-controlled clinical trial is designed to further evaluate the efficacy and safety of intracoronary delivery of autologous CD34+ cells (CLBS16) in subjects with CMD and without obstructive coronary artery disease.

“We are very excited about our CLBS16 program as it represents a potential breakthrough in the treatment of CMD, a condition which afflicts millions of patients in the US alone, many of whom are women. As a result, CMD is a women’s health issue of emerging importance as currently there are no products with approved labeling for coronary microvascular dysfunction,” said David J. Mazzo, PhD, President and Chief Executive Officer of Caladrius. “The treatment of the first patient in the FREEDOM trial is an important milestone for our Company and the program and we look forward to completing enrollment by the target of year-end 2021. It is especially noteworthy that even during the COVID-19 pandemic, physicians and patients are active in our trial, denoting the seriousness of the disease and underscoring the lack of available effective treatment for CMD.”

“Following the outstanding full data results from the ESCaPE-CMD study that I presented at SCAI 2020, we are very excited to participate in the FREEDOM trial,” said Timothy D. Henry, M.D., Medical Director of the Carl and Edyth Lindner Center for Research at The Christ Hospital Health Network. “Caladrius’ CLBS16 program has demonstrated great promise and I am looking forward to seeing how this new therapeutic option can benefit patients with CMD.”

About Coronary Microvascular Dysfunction

Coronary microvascular dysfunction is a type of non-obstructive coronary artery disease that causes decreased blood flow to the heart muscle that affects approximately 8.3 million people in the U.S.1,2 With common symptoms that include recurring, debilitating chest pain, tiredness, and shortness of breath, many CMD patients are undiagnosed because of the absence of large vessel obstruction. Due to an under appreciation of the disease, patients, the majority of whom are women, often go years without proper treatment. When a diagnosis of CMD is missed, patients are untreated and remain at high risk of heart attack and/or cardiovascular-related death.
