Published Peer-reviewed Initial Data From Biocardia Pivotal Phase 3 Clinical Trial Of Cardiamp Demonstrates Improvement In Heart Failure Patients Measured By Exercise Outcomes And Cardiac Function

Paper Published in International Journal of Cardiology Demonstrates Safety and Tolerability While Showing Functional Improvement at Six Months

SAN CARLOS, Calif. – October 26, 2020 – BioCardia®, Inc. [Nasdaq: BCDA](“BioCardia” or the “Company”), a leader in the development of comprehensive solutions for cardiovascular regenerative therapies, today announced the publication of data from the Company’s initial open-label roll-in cohort that served as the precursor for the Company’s ongoing CardiAMP™ Heart Failure (HF) Phase 3 clinical trial. Published in the International Journal of Cardiology, the study data shows that CardiAMP is a well-tolerated treatment in heart failure patients and demonstrated improved distance in six-minute exercise testing at six months and a trend toward improvement at one year. This 10-patient cohort was the feasibility test for the currently enrolling CardiAMP HF Phase 3 clinical trial.

The study, entitled “Point of care, bone marrow mononuclear cell therapy in ischemic heart failure patients personalized for cell potency: 12-month feasibility results from CardiAMP heart failure roll-in cohort,” followed 10 patients with chronic post-heart attack heart failure (NYHA class II and III) who underwent a 5 ml bone marrow aspiration to determine cell potency using the patented CardiAMP cell potency assay followed by CardiAMP cell therapy, consisting of bone marrow mononuclear cell (BM MNC) enrichment and transendocardial injection of 200 million BM MNCs, at a subsequent single point-of-care visit. The study followed those subjects for 12 months and showed no serious adverse events related to bone marrow or cell delivery. Importantly, improvement at six months was observed in Six Minute Walk distance (+47.8 meters, p=0.01) and trended to improvement at 12 months (+46.4 meters, p=0.06). Echocardiographic data substantiated the improved performance of patients, as better contractility was seen of the heart.

“These results surpassed what we saw in our Phase 2 trial in similar NYHA Class I, II, and III ischemic heart failure patients. Utilizing our cell potency assay is an important component of the CardiAMP treatment process, as it is the potency of the patients’ own cells that facilitates the regeneration and, therefore, the therapy. The results for these 10 patients are a meaningful marker for the heart failure community as a whole, and we believe it bodes well for our larger trial, for which these first patients laid the groundwork,” said BioCardia Chief Medical Officer Eric Duckers, M.D., Ph.D. “Our current CardiAMP HF trial is currently enrolling, and we anticipate full enrollment as early as the fourth quarter of 2021. In the meantime, we expect to receive the results from our data and safety monitoring board (DSMB) review by December 15, 2020.”

The published paper also reported 12-month trends toward improvement in a variety of cardiac functions, including left ventricular ejection fraction and recruitment of previously akinetic left ventricular wall segments. The 10-patient cohort also displayed trends toward improvement of NYHA heart failure functional class and overall quality of life. The International Journal of Cardiology article is currently available online here and is expected to be available in print in the coming weeks.
