October 19 - BioCardia Announces FDA Acceptance of De Novo Pre-Submission Package for Helix™ Catheter Marketing Clearance FDA Substantive Review and Meeting Expected this Quarter

October 19, 2026

BioCardia, Inc. [NASDAQ: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today announced the FDA has accepted its pre-submission package for marketing clearance of its Helix catheter (“Helix”) intended for therapeutic and diagnostic agent delivery. 
In May 2026, the Company and FDA met and reviewed our initial De Novo pre-submission package. FDA agreed that there are two pathways for Helix marketing clearance and raised no concerns regarding the product’s safety data, performance, or compatibility with general classes of agents. In August 2026, FDA confirmed and accepted the meeting minutes. In September 2026, the De Novo pre-submission was revised, incorporating the advice from FDA CDRH as detailed in the meeting minutes, re-submitted and has now been accepted by FDA. BioCardia expects FDA substantive review with written feedback, followed by a meeting with BioCardia to discuss approval via the De Novo pathway, this quarter.
The extensive clinical data and safety profile from fifteen clinical trials including nearly five hundred patients presents an opportunity for FDA to ensure that follow-on catheters demonstrate a similar level of safety and clinical experience to obtain clearance.
Marketing clearance of Helix by FDA has the potential to expand BioCardia’s opportunities to partner with developers of investigational cells, genes, and protein therapeutics requiring targeted delivery to the heart.

 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.

CardiAMP® autologous and CardiALLO™ allogeneic cell therapies are the Company’s biotherapeutic platforms for the treatment of heart disease.
