Independent Data Monitoring Committee advises continuation of trial without modification

No safety or tolerability concerns observed in the first two patients dosed

Top-line data from all subjects expected by the first quarter of 2023

BASKING RIDGE, N.J., May 19, 2022 (GLOBE NEWSWIRE) — Caladrius Biosciences, Inc. (Nasdaq: CLBS) (“Caladrius” or the “Company”), a clinical-stage biopharmaceutical company dedicated to the development of innovative therapies designed to treat or reverse disease, today announced that the Independent Data Monitoring Committee (“IDMC”) overseeing the Phase 1b, open-label, proof-of-concept study of CLBS201 for the treatment of diabetic kidney disease (“DKD”) has reviewed the initial safety and tolerability data from the first two, sequentially treated, patients. Based on their assessment of the data, the IDMC approved proceeding with the enrollment of the remaining four patients in the study without further review.

“We are very pleased with the progress of the study and with the recommendations of the IDMC,” stated Kristen K. Buck, M.D., Executive Vice President of R&D and Chief Medical Officer of Caladrius. “We find it encouraging that CLBS201 appeared to be well-tolerated based on the initial assessment of data. We look forward to continuing this study and hope to rapidly enroll the remaining patients, leading to top-line data by the first quarter of 2023.”

About the Phase 1b clinical trial of CLBS201 for the treatment of DKD

Progressive kidney failure is associated with attrition of the microcirculation of the kidney. Preclinical studies in kidney disease and injury models have demonstrated that protection or replenishment of the microcirculation results in improved kidney function. Based on these observations, the Company recently initiated a Phase 1, open-label, proof-of-concept trial evaluating CLBS201, a CD34+ regenerative cell therapy investigational product for intra-renal artery administration in patients with DKD. Patients selected for the study will be in the pre-dialysis stage of kidney disease and will exhibit rapidly progressing stage 3b disease. The protocol provides for a staggered, sequentially dosed cohort of six patients overseen by an IDMC with the objective of determining the tolerance of intra-renal cell therapy injection in DKD patients as well as the ability of CLBS201 to regenerate kidney function.

About Diabetic Kidney Disease

DKD, also called diabetic nephropathy, is a serious kidney-related complication of diabetes. Diabetes mellitus is the leading cause of kidney disease; approximately 40% of individuals with diabetes have DKD.

¹

Over time, high blood sugar from poorly controlled diabetes can damage the small blood vessels (microvasculature) in the kidneys, which can lead to kidney damage. This microvascular complication may eventually develop in approximately 30% of patients with type 1 diabetes and approximately 40% of patients with type 2 diabetes. All-cause mortality in patients with DKD is reported to be higher than in patients with diabetes without kidney disease.
