April 20, 2026 - BioCardia And Japan PMDA Align on Acceptability of CardiAMP Clinical Data to Support Regulatory Approval in Ischemic Heart Failure

April 20, 2026

BioCardia^®, Inc. [Nasdaq: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today reported a positive outcome in its formal clinical consultation with Japan's Pharmaceutical and Medical Device Agency (PMDA). PMDA has determined that the clinical safety and efficacy evidence for the CardiAMP^® Cell Therapy in ischemic heart failure is likely sufficient to support market clearance.

Good alignment was achieved in the meeting on the acceptability of the foreign clinical data that has been developed in the United States, the indications for use in patients, the approach for introduction of the therapy in Japan, and the need for continued post marketing studies in Japan. The Company will await the minutes from PMDA to provide detailed feedback and timeline for potential filing.

"We are thankful for PMDA's engagement and for the unanimous support of the world class cardiologists from Japan and the United States attending the meeting," said BioCardia Chief Executive Dr. Peter Altman. "We are on track to have the first minimally invasive biologic therapy in ischemic heart failure approved in Japan."
