Exhibit 99.1

BioCardia Announces Positive DSMB Review of CardiALLO Allogeneic Cell Therapy for Heart Failure Phase 1/2 Clinical Trial

Independent Data Safety Monitoring Board (DSMB) recommends that the study proceeds as designed based on 30-day data safety assessment of participants treated in low dosage group.

The company plans to progress the trial to enrollment of 39 participants in the United States.

Sunnyvale, Calif. – April 15, 2025 - BioCardia, Inc. [Nasdaq: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today announced that the study’s independent DSMB, which conducted a planned review of the 30-day safety data from the roll-in 20 million cell dosing cohort in the CardiALLO-HF trial, recommended that the study continue as designed. There have been no treatment emergent major adverse cardiac events observed nor has there been any clinical evidence of immune reactions to the allogeneic cells implanted.

“We are pleased with the DSMB’s recommendation, an important step forward in advancing this allogeneic off the shelf mesenchymal stromal/stem cell therapy,” said Peter Altman, BioCardia Chief Executive Officer. “Today’s result has potential to be helpful with ongoing discussions around nondilutive funding and partnering opportunities for our MSC platform. Success in this trial can enable future pivotal trial design and funding in the USA, conditional time limited approval with reimbursement in Japan, as well as the advancement of CardiALLO MSC therapy for the likely orphan indications of pediatric and adult congenital heart disease.”

Previous clinical results of MSC in ischemic heart failure from our co-sponsored TRIDENT trial^1^ demonstrated that higher MSC cell dosages reduced myocardial scar and increased left ventricular ejection fraction, and peer results^2^ have indicated that patients with active inflammation have sustained reduction in cardiovascular major morbidity. CardiALLO HF at high dosage is anticipated to have at least twice the effective dosage of these previous studies and will be the first trial to target patients with active inflammation.

About CardiALLO HF

The CardiALLO Heart Failure Trial is a Phase I/II study with an open label Phase I nine-patient dose escalation cohort, followed by a thirty-patient randomized double-blinded placebo procedure-controlled cohort, intended to develop support for safety and efficacy of this treatment. For Phase I, three patients are to be treated at one of three escalating doses of 20 million cells, 100 million cells, and 200 million cells, using the efficient Helix minimally invasive delivery system. The proprietary CardiALLO human MSCs and their dedicated proprietary catheter delivery system are manufactured at BioCardia’s facility in Sunnyvale, California.
