(Nasdaq: OBIO) (“Orchestra BioMed” or the “Company”), a biomedical company accelerating high-impact technologies to patients through risk-reward sharing partnerships, today announced that the U.S. Food and Drug Administration (“FDA”) has granted Breakthrough Device Designation (“BDD”) for atrioventricular interval modulation (“AVIM”) therapy. Specifically, the BDD is for an implantable system (i.e., a pacemaker) to deliver AVIM therapy using conduction system pacing to reduce blood pressure in patients with increased ten-year atherosclerotic cardiovascular disease (“ASCVD”) risk, preserved left ventricular systolic function, and uncontrolled hypertension, despite the use of anti-hypertensive medications or in patients who may have intolerance to anti-hypertensive medications. Orchestra BioMed estimates that there are over 7.7 million patients in the U.S. that meet the criteria for the BDD for AVIM therapy. AVIM therapy is currently being evaluated under an FDA investigational device exemption (“IDE”) in the BACKBEAT global pivotal study which is being conducted by Orchestra BioMed in collaboration with Medtronic. The BACKBEAT pivotal study is enrolling pacemaker-indicated patients with uncontrolled hypertension despite the use of anti-hypertensive medication, a key subpopulation under the BDD for which Orchestra BioMed believes AVIM therapy may offer optimal clinical benefit. “We are delighted to have received FDA Breakthrough Device Designation for AVIM therapy which has the potential to offer a differentiated, advantageous solution for hypertension management in a broad population,” commented David Hochman, Chairman and Chief Executive Officer of Orchestra BioMed. “Patients at higher risk for mortality and morbidity associated with high blood pressure are the core of the population we are actively enrolling in the BACKBEAT global pivotal study of hypertensive pacemaker-indicated patients in collaboration with Medtronic. The FDA Breakthrough Device Designation recognizes the potential of this unique therapy to benefit a significantly expanded number of patients who are not indicated for a pacemaker but who also have uncontrolled hypertension and increased cardiovascular risk. We are committed to working closely with the FDA, Medtronic and the clinical community to maximize the impact of AVIM therapy.” The FDA Breakthrough Devices Program, which reflects the FDA’s commitment to device innovation and protecting public health, is designed to expedite the development and provide priority review of innovative medical technologies that have the potential to significantly improve outcomes for patients with serious or life-threatening conditions. To be eligible for this designation, a device must demonstrate the potential to provide more effective treatment or diagnosis of a life-threatening or irreversibly debilitating condition. In addition, the device must meet at least one of the following criteria: it must represent breakthrough technology, have no approved or cleared alternatives, offer significant advantages over existing options, or be determined by the FDA to be in the best interest of patients. Beyond regulatory acceleration, the Breakthrough designation may also support favorable reimbursement pathways, including eligibility for incremental inpatient reimbursement through the New Technology Add-on Payment (“NTAP”) and outpatient Transitional Pass-Through payments (“TPT”) under the Center for Medicare & Medicaid Services (“CMS”) programs. These mechanisms may help facilitate more timely access to breakthrough technologies while supporting provider adoption and patient access. “We are very pleased that AVIM therapy received Breakthrough Device Designation, a recognition of the potential of AVIM therapy to address unmet needs in hypertension management,” said Robert C. Kowal, M.D., Ph.D., Vice President and General Manager of Cardiac Pacing Therapies within the Medtronic Cardiac Rhythm Management operating unit. “Hypertension remains a significant global public health challenge that is especially relevant to the pacemaker population as the most common comorbidity in these patients. Medtronic is committed to collaborating with Orchestra BioMed to advance this innovative, investigational therapy through the BACKBEAT global pivotal study.” Orchestra BioMed has a strategic collaboration with Medtronic, the global market leader in cardiac pacing therapies, for development and commercialization of AVIM therapy for the treatment of uncontrolled hypertension in pacemaker-indicated patients. Under the terms of the existing collaboration agreement, Medtronic holds the right of first negotiation to expand its licensing agreement with Orchestra BioMed to obtain global rights to commercialize AVIM therapy for the treatment of uncontrolled hypertension in patients that do not have an indication for a pacemaker. About Orchestra BioMed Orchestra BioMed (Nasdaq: OBIO) is a biomedical innovation company accelerating high-impact technologies to patients through risk-reward sharing partnerships with leading medical device companies. Orchestra BioMed’s partnership-enabled business model focuses on forging strategic collaborations with leading medical device companies to drive successful global commercialization of products it develops.

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. About the FDA Breakthrough Device Program The FDA Breakthrough Device Program, established in 2015, is designed to expedite the development, review, and potential market access of medical devices that may offer more effective treatment or diagnosis for life-threatening or irreversibly debilitating conditions. The designation provides manufacturers with prioritized FDA review and early, frequent interactions with agency experts to efficiently address development and regulatory considerations. Breakthrough status may also support streamlined reimbursement pathways, including eligibility for New Technology Add-on Payments (NTAP) and Transitional Pass-Through Payments (TPT), by helping to demonstrate substantial clinical improvement.
