Orchestra BioMed Reports First Quarter 2025 Financial Results and Highlights Recent Regulatory and Clinical Milestones

• FDA Breakthrough Device Designation Awarded to AVIM Therapy
• FDA IDE Approved for Virtue SAB U.S. Pivotal Trial for Launch

NEW HOPE, Pa., May 12, 2025 (GLOBE NEWSWIRE) -- Orchestra BioMed Holdings, Inc. (NASDAQ:OBIO, "Orchestra BioMed" or the "Company")), a biomedical company accelerating high-impact technologies to patients through risk-reward sharing partnerships, today announced financial results for the first quarter ended March 31, 2025, and provided a business update highlighting continued regulatory momentum, disciplined operational execution, and a strengthening clinical development pipeline.

Q1 2025 Highlights:

• U.S. Food and Drug Administration ("FDA") Breakthrough Device Designation ("BDD") granted for atrioventricular interval modulation ("AVIM") therapy in patients with uncontrolled hypertension and increased cardiovascular risk, with or without an indication for a pacemaker, marking a major regulatory validation of the therapy's potential to improve hypertensive heart disease outcomes. FDA BDD enables prioritized regulatory interactions and strengthens potential access to add-on reimbursement.
• BACKBEAT Global Pivotal Study execution continuing to progress in strategic collaboration with Medtronic (NYSE:MDT).
• New Clinical Data presented demonstrating the favorable impact of AVIM therapy on cardiac function in patients with diastolic dysfunction, a key contributor to the development of heart failure, as late breaker at THT 2025.
• Intellectual Property Expansion continues with AVIM therapy patent estate reaching 137 issued patents worldwide, with recent additions bolstering coverage for both hypertension and heart failure indications.
• FDA Investigational Device Exemption ("IDE") Approval received for the Virtue® Sirolimus AngioInfusion Balloon ("SAB") U.S. pivotal trial, a randomized head-to-head study comparing Virtue SAB with the commercially available AGENT^TM DCB paclitaxel-coated balloon (the "Virtue Trial"). Trial initiation is currently targeted for the second half of 2025.
  • Orchestra BioMed is sponsoring and in full operational control of the Virtue Trial; mediation with Terumo of certain other contractual terms is progressing.

Key Chief Executive Officer ("CEO") Commentary:

David Hochman, Chairman and CEO of Orchestra BioMed, stated: "We continued to make meaningful progress during the first quarter with significant inflection points for both our AVIM therapy and Virtue SAB programs. We believe the FDA's Breakthrough Device Designation for AVIM therapy signals meaningful recognition of its potential to meet the clinical needs of millions living with hypertensive heart disease, a population in which chronic high blood pressure can lead to various heart problems like left ventricular hypertrophy, diastolic dysfunction, heart failure, and coronary artery disease. We believe that AVIM therapy has the potential to provide a potent additional therapeutic option for these patients. We are focused on execution of the BACKBEAT global pivotal study alongside our strategic partner Medtronic as the critical pathway toward making AVIM therapy available to patients globally."

Mr. Hochman continued, "In parallel, we secured full IDE approval to conduct the Virtue Trial, a U.S. pivotal coronary study that will evaluate Virtue SAB, our investigational, non-coated drug-eluting balloon designed to deliver a large liquid dose of proprietary extended-release sirolimus, head-to-head against the commercially available AGENT paclitaxel-coated balloon. We believe the updated design of the trial, which we currently plan to initiate in the second half of the year, offers the most direct path to regulatory approval while showcasing the distinctive pharmacokinetic and therapeutic advantages of our proprietary technology. Taken together, these milestones mark tangible progress on multiple fronts. We continue to execute methodically and remain focused on advancing our pivotal trials, generating clinical evidence, and building long-term value for patients, physicians, shareholders and strategic partners alike."

Financial Results for the First Quarter Ended March 31, 2025

• Cash and cash equivalents and Marketable securities totaled $49.9 million as of March 31, 2025.
• Net cash used in operating activities and for the purchase of fixed assets was $16.7 million during the first quarter of 2025, compared with $13.1 million for the first quarter in 2024, with the primary driver being increased research and development costs during the first quarter of 2025.
• Revenue for the first quarter of 2025 was $0.9 million, compared with $0.6 million for the first quarter in 2024. The increase was primarily due to recognition of partnership revenues earned under the agreement with Terumo.
• Research and development expenses for the first quarter of 2025 were $13.5 million, compared with $9.1 million for the first quarter in 2024. The increase was primarily due to additional costs associated with the ongoing BACKBEAT global pivotal study.
• Selling, general and administrative expenses for the first quarter of 2025 were $6.3 million, compared with $5.9 million for the first quarter of 2024. The increase was primarily due to an increase in stock-based compensation and increased professional fees associated with the overall growth of the business.
• Net loss for the first quarter of 2025 was $18.8 million, or $0.49 per share, compared with a net loss of $13.5 million, or $0.38 per share, for the first quarter of 2024. Net loss for the first quarter of 2025 included $3.0 million in non-cash stock-based compensation expense as compared to $2.6 million for the same period in 2024.

About AVIM Therapy

AVIM therapy is an investigational therapy compatible with standard dual-chamber pacemakers designed to substantially and persistently lower blood pressure. It has been evaluated in pilot studies in patients with hypertension who are also indicated for a pacemaker. MODERATO II, a double-blind, randomized pilot study, showed that patients treated with AVIM therapy experienced net reductions of 8.1 mmHg in 24-hour ambulatory systolic blood pressure (aSBP) and 12.3 mmHg in office systolic blood pressure (oSBP) at six months when compared to control patients. In addition to reducing blood pressure, clinical results using AVIM therapy demonstrate improvements in cardiac function and hemodynamics. The BACKBEAT (BradycArdia paCemaKer with atrioventricular interval modulation for Blood prEssure treAtmenT) global pivotal study will further evaluate the safety and efficacy of AVIM therapy in lowering blood pressure in patients who have systolic blood pressure above target despite anti-hypertensive medication and who are indicated for or have recently received a dual-chamber cardiac pacemaker. AVIM therapy has been granted Breakthrough Device Designation by the FDA for the treatment of uncontrolled hypertension in patients who have increased cardiovascular risk.

About Virtue SAB

Virtue SAB is an investigational therapeutic combination drug-device designed to deliver a proprietary extended-release formulation of sirolimus, SirolimusEFR™ through a non-coated microporous AngioInfusion™ Balloon, protecting the drug in transit through the arteries and consistently delivering a large liquid dose, overcoming certain limitations of drug-coated balloons. SirolimusEFR delivered by Virtue SAB has been shown in published preclinical series involving hundreds of arterial deliveries to achieve sustained tissue levels well above the known required therapeutic tissue concentration for inhibiting restenosis (1 ng/mg tissue) for the entire critical healing period of approximately 30 days. Virtue SAB demonstrated positive three-year clinical data in coronary in-stent restenosis ("ISR") in the SABRE study, a multi-center prospective, independent core lab-adjudicated clinical study conducted in Europe. Virtue SAB has been granted Breakthrough Device Designation by the FDA for specific indications relating to coronary ISR, coronary small vessel disease and peripheral artery disease below-the-knee. The FDA granted IDE approval for Orchestra BioMed to evaluate the efficacy and safety of Virtue SAB in the Virtue Trial, a pivotal trial that will randomize Virtue SAB against commercially available AGENT^TM DCB, a paclitaxel-coated balloon.
