Treatment continues to be well-tolerated and deemed non-futile for therapeutic effect

BASKING RIDGE, N.J. (March 8, 2018) – Caladrius Biosciences, Inc. (Nasdaq:CLBS) (“Caladrius” or the “Company”), a development-stage biopharmaceutical company with multiple technology platforms targeting autoimmune and select cardiovascular indications, reports results from the predetermined interim analysis in The Sanford Project: T-Rex Study, a prospective, randomized, placebo-controlled, double-blind Phase 2 clinical trial of 110 patients to evaluate the safety and efficacy of the Company’s CLBS03 as a treatment for recent-onset type 1 diabetes (“T1D”).

The interim analysis was triggered by 50% of the targeted total number of subjects in the trial completing six months of follow-up. The interim analysis, conducted by independent statisticians, showed that CLBS03 continues to be well-tolerated and led to the conclusion that the study was non-futile as determined by pre-defined futility criteria for therapeutic effect.

CLBS03 is a personalized autologous cell therapy consisting of each patient’s own regulatory T cells (“Tregs”) which have been expanded in number and functionally enhanced by a proprietary method developed through a collaboration with Jeffrey Bluestone, Ph.D., and renowned researchers at the University of California, San Francisco. Caladrius holds exclusive rights to an international portfolio of issued and pending patents related to this product. CLBS03 as a treatment for T1D has U.S. Food and Drug Administration (“FDA”) Orphan Drug designation, European Medicine Agency Advanced Therapeutic Medicinal Product classification and FDA Fast Track designation, which represents the first T1D program to receive this distinction.

“The results of this interim analysis show that CLBS03 remains well-tolerated and that a positive outcome for therapeutic effect at the end of the trial remains a statistical possibility. Of course, we have long anticipated that an analysis of the complete data set at the end of the study would be necessary to fully understand the impact of CLBS03 treatment on patients with recently-diagnosed T1D,” stated David J. Mazzo, Ph.D., President and Chief Executive Officer of Caladrius. “We look forward to completing and reporting on the 12-month follow-up on all 110 patients in early 2019 and using the complete results to determine the next steps in our development plan.”

The Phase 2 T-Rex study is being conducted with support from Sanford Research, a Sanford Health subsidiary, a grant from the California Institute for Regenerative Medicine and a grant from the Juvenile Diabetes Research Foundation.

About The Sanford Project: T Rex Study

The landmark T-Rex study, which is being conducted in collaboration with Sanford Research, a Sanford Health subsidiary, is a prospective, randomized, placebo-controlled, double-blind Phase 2 clinical trial to evaluate the safety and efficacy of CLBS03 as a treatment for T1D in approximately 110 subjects age 8 to 17 with recent-onset T1D. Subjects are randomized into one of three groups to receive, through a single administration, either a high dose of CLBS03, a low dose of CLBS03 or a placebo. Enrollment of the first cohort of 19 subjects, designated for a preliminary safety evaluation, was completed in August 2016. The evaluation of safety data from this group was satisfactory and the Company began enrollment of the second cohort of subjects in October 2016. The key endpoints for the trial are the standard medical and regulatory endpoints for a T1D trial and include preservation of C-peptide (an accepted measure for pancreatic beta cell function), insulin use, severe hypoglycemic episodes and glucose and hemoglobin A1c levels to be evaluated when all patients complete 12-month follow-up.
