Current report

Clinical data from a 10-patient roll in cohort was published in 2021 in the International Journal of Cardiology. These results concluded that all CardiAMP HF protocol procedures were feasible and well tolerated. Favorable functional, echo and quality of life trends suggest this approach may offer promise. Thereafter, the randomized study enrolled 115 advanced heart failure patients on guideline directed medical therapy, in addition to the initial 10-patient roll-in cohort.

Current report

In patients with elevated NTproBNP biomarkers (50% of enrolled patients) compared to patients on optimized heart failure medication regimens alone had:

Current report

On March 2, 2026, CardiAMP HF echocardiography clinical results measured by the blinded echocardiography core laboratory at the Yale University Cardiovascular Research Group were presented at the Late Breaking Clinical trial session at the Technology and Heart Failure Therapeutics conference in Boston Massachusetts. Results showed positive evidence of decreased pathological left ventricular remodeling over time in patients receiving CardiAMP cell therapy treatment compared to patients not receiving the treatment. These results correlated to findings for the trial primary and key secondary endpoints of reduced fatal and non-fatal major adverse cardiovascular events and improved quality of life measures for treated patients. The Yale core laboratory measured both left ventricular end diastolic volume, when the heart ventricle is fully dilated (p = 0.06), and the left ventricular end systolic volume, when the heart is fully contracted (p=0.09). For the prespecified subgroup of patients having elevated biomarkers of heart stress, the differences between the treated and control patients were both clinically meaningful (>20ml/m2 and 15 ml/m2, respectively) and statistically significant (p = 0.02 and p = 0.01, respectively).

Current report

We are exploring approval for market release of CardiAMP in the United States with FDA, and in Japan with PMDA, based on the strength of this excellent but imperfect data. Approvals in both countries are at minimum expected to require post marketing studies to gather additional evidence of safety and efficacy. In the U.S., we expect to file a Q-Sub request with FDA on approvability of the FDA designated Breakthrough CardiAMP cell therapy device based on its safety and compelling signals of benefit in patients with elevated biomarkers of heart stress. These discussions will be simplified by reference to the Helix as a stand-alone delivery device, which has a pre-submission actively under review by FDA. In Japan, we have completed a number of preclinical consultations with PMDA on the approvability of the CardiAMP Cell Therapy System. We have scheduled a formal clinical consultation to align with PMDA on the acceptability of the existing clinical data from the three trials to allow us to submit for market release.

Current report

In February 2026, we announced a 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 clinical trials of cell and gene therapy delivery to the heart using Helix, where patients were enrolled in three primary cardiac clinical indications. FDA has accepted the Helix pre-submission and has confirmed that it contains all of the necessary elements and information needed to proceed with substantive review. We are scheduled to meet with the FDA in the second quarter of 2026, and we expect to receive written feedback. We expect that the FDA Center for Devices and Radiological Health (CDRH) will lead the review in consultation with the FDA Center for Biologics Evaluation and Research (CBER). The FDA has acknowledged to us that the CBER Breakthrough Designation on the Helix enables in the CardiAMP Cell Therapy for ischemic heart failure.

Previous report

We have submitted the Annual Report for the CardiAMP Heart Failure Trial to FDA, which details our plans for completing patient follow-up and we intend to request a meeting with FDA to discuss the results with respect to approvability of the CardiAMP Cell Therapy System. We also completed a supplementary submission to Japan Pharmaceutical and Medical Device Agency (PMDA) providing answers to PMDA’s previous responses on the approvability of the CardiAMP Cell Therapy System based on U.S. data and had a consultation in November 2024, as preparation for a subsequent clinical consultation after results from the CardiAMP Heart Failure Trial are available. Should results meet expectations, there is potential for approval based on this and previous clinical data.

Previous report

This trial also includes a 30-day window after patient consent and before baseline measures. This is intended to address the Hawthorne effect, where patient behavior changes can occur after they are under closer observation of their care providers. We have multiple consented patients in the screening queue and many sites that are at various stages of the onboarding process.

Previous wording

The CardiAMP Heart Failure Trial is a randomized, double-blinded, placebo procedure controlled, multi-center pivotal clinical trial for the treatment of heart failure of reduced ejection fraction (HFrEF). The trial is assessing the safety and effectiveness of the CardiAMP Cell Therapy System for the treatment HFrEF, an investigational device system that has received Breakthrough Device Designation from the FDA. The CardiAMP autologous cell therapy is delivered during a standard minimally invasive catheter-based procedure. Patients are typically discharged after an overnight stay. The cell therapy is designed to promote microvascular repair through enhanced capillary density and reduced fibrosis, both of which have been demonstrated in small and large animal models of disease.

This confirmatory trial focuses on patients in active heart failure who demonstrated the greatest benefits in the interim results of the CardiAMP Heart Failure I Trial.

Previous wording

In August 2024, the FDA approved a protocol amendment for the this trial, which allows patients who would have previously been excluded from treatment to receive additional cell deliveries to achieve the same target minimum dosage utilizing a treatment plan informed by the preprocedural CardiAMP Cell Population Analysis (CPA). The CPA approach was developed to select patients most likely to respond to therapy based on their therapeutic cell composition at screening. Utilizing available clinical results allowed us to refine the algorithm in the CardiAMP Heart Failure II Trial and develop a personalized treatment plan for patients below the CPA acceptance criteria. Such treatment plans adjust the number of dosing aliquots for patients with lower concentrations of important specified cells. Combined, the algorithm modifications and development of the treatment plan approach are expected to increase the number of patients eligible for the trial.

Previous wording

The CardiAMP Cell Therapy Chronic Myocardial Ischemia Trial is a Phase III, multi-center, randomized, double-blinded, placebo-controlled study of up to 343 patients at up to 40 clinical sites. The Phase III pivotal trial is designed to provide the primary support for the safety and efficacy of the CardiAMP Cell Therapy System for patients with no option chronic myocardial ischemia with refractory angina (BCDA-02). These patients experience frequent angina (i.e., chest pain) attacks that are uncontrolled by optimal drug therapy, and these patients are not suitable candidates for stent placement or bypass surgery, leaving them few therapeutic options. Our therapeutic approach uses many of the same novel aspects used in the CardiAMP Heart Failure Trial and is expected to leverage our experience and investment in the heart failure trial.

Previous wording

Based upon our current operating plan, we believe that the cash and cash equivalents of approximately $2.4 million as of December 31, 2024 are not sufficient to fund our planned expenditures and meet our obligations beyond May 2025. In order to continue development of our therapeutic candidates beyond such time, we plan to raise additional capital, potentially including non-dilutive collaboration and licensing arrangements, debt or equity financing, or a combination from these sources. We may be unsuccessful in raising funds from any or all such sources, and to the extent we raise any funds, they may be on highly dilutive terms. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of our therapeutic candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development of our therapeutic candidates.

We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of our therapeutic candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development of our therapeutic candidates.
