BioCardia Awarded New U.S. Patent Covering Helix System for Local Biotherapeutic Delivery of Autologous and Allogenic Cells to the Heart

April 28, 2020

SAN CARLOS, Calif. – BioCardia®, Inc., [NASDAQ: BCDA], a leader in the development of comprehensive solutions for cardiovascular regenerative therapies, today announced the issuance of United States Patent No. 10,632,281, entitled “Drug Delivery Catheters that Attach to Tissue and Methods for Their Use.” This new patent provides additional, broad protection for the Helix™ Biotherapeutic Delivery System and covers the use of the helical needle delivery system with a deflectable guide catheter. The U.S. Patent Office has extended the life of this patent for 2.8 years beyond the usual 20-year term.

Published literature has shown that the Helix System presents the lowest risk to patients for biotherapeutic delivery compared to other delivery methods evaluated,1 and is three to six times more efficient at delivering cells to the heart muscle than other methods.2 The Helix System is believed to be the only CE Marked intramyocardial delivery system and the only intramyocardial delivery system in clinical use today.

“The Helix System is a key element in our CardiAMP® and CardiALLO™ cell therapy programs and is also being used by partners such as AstraZeneca, CellProThera and leading academic institutions in their biotherapeutic development programs,” said Peter Altman, PhD, chief executive officer of BioCardia. “This is just one of many patents that protect our signature delivery system, allowing us to provide physicians with compelling -- and differentiated -- technology they need to enable safe and efficient local biotherapeutic delivery to the heart.”

The Helix System is currently being evaluated in the U.S. Phase III pivotal CardiAMP Heart Failure Trial along with the company’s lead cell therapy candidate (CardiAMP), which uses a patient’s own (autologous) bone marrow cells delivered to the heart in a minimally-invasive procedure to potentially stimulate the body’s natural healing response.
