PLANO, Texas--(BUSINESS WIRE)--Oct 28, 2025--

Secretome Therapeutics today announced the launch of a Phase 1, dose-escalating trial of STM-01, Secretome’s neonatal cardiac progenitor cell (nCPC) product, for the treatment of heart failure in young adults with dilated cardiomyopathy (DCM). This trial, and a subsequent dose-escalating Phase 1 of STM-01 in pediatric DCM, are funded through a grant from The Marcus Foundation and will take place at Children’s Healthcare of Atlanta.

Pediatric DCM is a rare but life-threatening form of heart failure that affects between 500 and 1,000 children in the United States. The disease is diagnosed on average at 2 years of age, and without heart transplantation, life expectancy is 5 years after diagnosis on average. Preclinical studies conducted in the laboratories of Michael Davis, Ph.D. at Emory University and Georgia Tech, and Sunjay Kaushal, M.D., Ph.D. at the University of Maryland, Baltimore indicate that nCPC produce marked improvements in cardiac function in both adult and juvenile animal models of heart failure.

“Our preclinical published results in animals suggest that, compared to mesenchymal stem cells from older donors, STM-01 is uniquely potent at improving ejection fraction and treating heart failure,” said Michael Davis, Ph.D., Director of the Emory and Children’s Heart Research and Outcomes Center and Professor of Cardiology and Biomedical Engineering at the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. “We are grateful for the support from The Marcus Foundation to now study this potentially groundbreaking new therapy in adults and children with DCM who truly need a new treatment option.”

The Phase 1 trial in adult patients with DCM will study the safety of multiple ascending doses of STM-01. If safe and well-tolerated, STM-01 will proceed to a Phase 1 multiple ascending dose study in pDCM. Both trials will occur at the Marcus Center for Cellular Therapy at Children's Arthur M. Blank Hospital.

“The launch of this clinical study is the first step towards offering a new class of therapies to adult and pediatric patients suffering from DCM,” said Vinny Jindal, President and Chief Executive Officer of Secretome Therapeutics. “We are honored to work with the teams at Children’s, Emory, and The Marcus Foundation to study STM-01 in this lethal and underserved disease.”
