SAN DIEGO, CA, USA I January 19, 2023 I Stemedica Cell Technologies, a best-in-class manufacturer of ischemic tolerant, allogeneic mesenchymal stem cells (itMSC), announced today that it has initiated its “PHASE IIB/III, MULTICENTER, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED STUDY TO ASSESS THE EFFICACY, SAFETY, AND TOLERABILITY OF A SINGLE INTRAVENOUS INJECTION OF ALLOGENEIC MESENCHYMAL STEM CELLS TO SUBJECTS WITH ISCHEMIC STROKE” under an existing US IND using its itMSC product.

Stemedica plans to initiate a Phase IIb/III, multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy, safety, and tolerability of a single intravenous injection of allogeneic mesenchymal stem cells to subjects with ischemic stroke. The primary objective of this study is to evaluate the efficacy of an IV injection of itMSCs for improvement in clinical outcomes of the upper-extremity portion of the body as measured on the Fugal-Meyer Scale in subjects with ischemic stroke at Day 0 through Month 6.

Secondary endpoints of the study include measuring change from the baseline in the modified Rankin Scale and Barthel Index, as well as the safety and tolerability of Stemedica’s itMSCs. Approximately 300 subjects will be enrolled in the Study, where they will be randomized into two cohorts; one receiving an IV injection of Stemedica’s itMSCs at Day 0 and standard treatment and the other cohort receiving placebo and standard treatment.

Stemedica successfully completed a Phase I/II Study of Safety and Preliminary Efficacy of Intravenous Allogeneic Mesenchymal Stem Cells in Chronic Stroke in patients with chronic ischemic stroke and demonstrated an excellent safety profile of itMSCs. Statistically significant improvements were observed in study participants in four efficacy endpoints: NIH Stroke Scale (NIHSS) for neurological assessment, Barthel Index (BI) for ability to perform daily tasks, Mini-Mental Status Exam (MMSE) for mental status, and Geriatric Depression Scale (GDS) for degree of depression. The study was conducted at three centers: University of California, San Diego (UCSD); Mercy Gilbert Medical Center; Gilbert, Arizona; and University of California, Irvine (UCI).

“It is critical to address the enormous medical and social issues caused by approximately ten million new cases of stroke each year around the world. We are encouraged that Stemedica’s Phase IIb/III clinical trial under the FDA IND can validate the role that our ischemic tolerant mesenchymal stem cells can play in addressing this crisis,” said Dr. Nikolai Tankovich, Stemedica’s President and Chief Medical Officer. “Stemedica has begun discussions with possible Strategic Partners that have a deep commitment to advancing treatment solutions for stroke and see Stemedica’s study design and product uniqueness as a keen strategic advantage in today’s marketplace.”

“To date, there are no effective drugs or therapies available for the treatment of chronic ischemic stroke with current treatments primarily relying on rehabilitation to prevent further degradation. We hope to bring this medication to patients with this debilitating condition,” said Dr. Lev Verkh, Chief Regulatory and Clinical Development Officer. “Unlike other stroke trials using stem cells, this is the first clinical trial of its kind, evaluating Stemedica’s itMSCs. We believe the unique nature of our low oxygen-manufactured cells will yield favorable cell proliferation, gene expression, cytokine production, and effective cell migration as part of positive patient responses to treatment using Stemedica’s itMSCs.”

About Stroke

Stroke is among the leading causes of death and disability in adults. In 2019, over 10 million new cases were reported globally, and over 6 million died due to stroke. Ischemic stroke incidents comprise nearly 90% of all strokes. The mean survival post stroke is 6 to 7 years with more than 85% of patients living past the first year post stroke, enduring years of disability and neuropsychiatric syndrome. Once entering the chronic stage of stroke, the patient’s welfare is affected, and significant family and societal burdens are experienced. To date, there are no effective drugs or therapies available for the treatment of chronic stroke; therefore, medical and social experts believe it is vitally important to identify new approaches in treating those afflicted by ischemic stroke.
