BioCardia Announces CardiAMP Chronic Myocardial Ischemia Trial Top Line Data of Roll-in Cohort Show Improved Exercise Tolerance and Reduced Angina Episodes at Six-Month Primary Follow-up
SUNNYVALE, Calif., Sept. 18, 2025 (GLOBE NEWSWIRE) -- BioCardia, Inc. (NASDAQ:BCDA), a developer of cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today announced the primary endpoint results of the open label roll-in cohort of the CardiAMP® Cell Therapy in Chronic Myocardial Ischemia Trial.
Results from the open label roll-in cohort patients having chronic myocardial ischemia with refractory angina show that the minimally-invasive CardiAMP Cell Therapy procedure was well tolerated with no treatment emergent major adverse cardiac events. All patients were on guideline-directed medical therapy (GDMT) and responded positively to the autologous cell therapy. Patients experienced increased exercise tolerance of an average of 80 seconds and an average of 82% reduction in angina episodes at the six-month primary endpoint when compared to measurements prior to cell therapy treatment. Sixty percent of the patients showed substantial improvements in both measures.
These early, open-label results compare favorably to those demonstrated by current FDA approved therapies such as Ranolazine and Enhanced External Counter Pulsation (EECP) (1,2,3). Patients already on Ranolazine experienced dramatic reduction in angina episodes at the six-month follow-up. These results are in line with previous compelling investigational trial results utilizing cost prohibitive cell therapy (4).
"With these final roll-in results, this novel investigational therapy shows promise in addressing debilitating refractory angina, a significant unmet need for patients with chronic myocardial ischemia," said Carl Pepine, MD, MACC, Professor of Medicine, Division of Cardiovascular Medicine, University of Florida at Gainesville.
"We are working with our investigators to submit these results for peer reviewed scientific publication," said Peter Altman, President and CEO. "The results from this roll-in cohort supports our continued development of this novel therapeutic approach for chronic myocardial ischemia with refractory angina and enhances the value of our CardiAMP cell therapy platform."
About Chronic Myocardial Ischemia with Refractory Angina
Chronic myocardial ischemia occurs in the setting of coronary artery disease when there is reduced blood flow to the heart. This causes angina, a type of chest pain which is characterized as refractory angina when this pain cannot be controlled by a combination of optimal medical therapy, angioplasty or bypass surgery, and is estimated to impact 600,000 to 1.8 million patients in the United States. Up to 15% of patients who have ischemia or angina and undergo cardiac catheterization are suboptimal candidates for conventional revascularization. Although prognosis of refractory angina has improved in recent years, patients with refractory angina experience a significantly impaired quality of life with disproportionately high utilization of healthcare services. These observations reflect the great need for new therapies for these patients. Promising results in treating this patient population with an autologous bone marrow derived cell therapy have been shown previously (4).
About the CardiAMP Cell Therapy Program
Designated by the FDA as a Breakthrough Therapy for Ischemic Heart Failure, CardiAMP Cell Therapy uses a patient's own bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure to potentially stimulate the body's natural healing response. CardiAMP Cell Therapy incorporates three proprietary elements not previously utilized in investigational cardiac cell therapy: a pre-procedural cell analysis for patient selection, a high target dosage of cells, and a proprietary delivery system that has been shown to be safer than other intramyocardial delivery systems and exponentially more successful in cell retention. The CardiAMP cell therapy trials for the indications of both chronic myocardial ischemia and ischemic heart failure are covered by the Center for Medicare and Medicaid for both treatment and control procedures. CAUTION - Limited by United States law to investigational use.
