## Article Body
BioCardia, Inc. [Nasdaq: BCDA], a developer of cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today reported it has completed its Pre-Submission to FDA under its Q-Submission program for the approval of its Helix Transendocardial Delivery Catheter (“Helix”) for intramyocardial therapeutic and diagnostic agent delivery.

The data supporting safety and effectiveness for the Helix Pre-Submission is from fifteen well-controlled clinical trials of cell and gene therapy delivery to the heart using Helix, where patients were enrolled in three primary cardiac clinical indications. The Helix Pre Submission has been made under the CardiAMP Cell Therapy System FDA Breakthrough Designation, which the Helix underlies. BioCardia seeks to align with FDA on the regulatory pathway and timing for approval in the next 45 days. An application for market clearance could soon follow.

“This Pre-Submission and discussion with FDA should lead to our Helix catheter being the first approved transendocardial delivery catheter system in the United States,” said Peter Altman, PhD, BioCardia’s President and CEO. “FDA clearance of Helix will streamline the future approvals of BioCardia’s autologous and allogeneic cell therapies for the treatment of Heart Failure and Chronic Myocardial Ischemia. Approval should also reduce development risk for biopharmaceutical and biotechnology partners seeking to employ our best-in-class minimally invasive delivery technology for cardiovascular cell, gene, and protein development programs aiming to address enormous unmet medical needs.”

About the Helix Transendocardial Delivery Catheter The Helix transendocardial delivery catheter is an enabling platform for minimally invasive targeted delivery of therapeutic and diagnostic agents to the heart intramyocardially. It enables agents to be delivered precisely within the heart with superior retention over other therapeutic delivery modalities, and to many regions of the heart that other delivery methods cannot reach. The Helix includes a specialized small distal helical needle which engages the heart tissue from within the chamber of the heart and provides stability within the dynamic beating heart to safely enable agent delivery.

The Helix delivery catheter is intended to be used by interventional cardiologists, electrophysiologists, and cardiac surgeons trained to perform endovascular and transendocardial procedures. In independent reviews of clinical experience with Helix relative to other transendocardial delivery catheters, it has shown superior procedural safety 1 and in pre-clinical studies has demonstrated a three-fold increase in effective dosing compared to open surgical access intramyocardial biotherapeutic delivery and eighteen-fold increase compared to intracoronary artery infusion 2 . The Helix catheter is further enhanced by BioCardia’s FDA approved Morph ® DNA™ steerable introducer product, which physicians use to navigate the Helix with superior control in the heart.
