Orchestra BioMed Presents New Data Showing Sustained Clinically Meaningful Reduction In 24-Hour Ambulatory Systolic Blood Pressure In Hypertensive Pacemaker Patients Treated With AVIM Therapy For Over 3 Years
- 8.9 mmHg mean reduction in 24-Hour ambulatory systolic blood pressure at average of 3.6 years from initiation of AVIM therapy in patients who participated in the MODERATO II study
- Orchestra BioMed is actively enrolling patients in the BACKBEAT pivotal study of AVIM therapy in hypertensive pacemaker patients
NEW HOPE, Pa., Feb. 26, 2024 (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 the presentation of new data demonstrating the long-term effect of atrioventricular interval modulation ("AVIM") therapy (also known as BackBeat CNT™) on generating clinically-meaningful reductions in 24-hour ambulatory systolic blood pressure ("aSBP") in pacemaker-indicated patients with uncontrolled hypertension despite the use of antihypertensive medications. The data were presented by Avi Fischer, M.D., Senior Vice President of Medical Affairs and Innovation of Orchestra BioMed in a scientific session at the Innovation in Cardiovascular Interventions ("ICI") 2024 Meeting.
"People who suffer from hypertension face a lifelong burden of blood pressure management. This is particularly relevant in the pacemaker-indicated population of older patients who have a higher risk of other co-morbidities and adverse clinical outcomes," commented Dr. Fischer. "These new long-term follow up data demonstrate AVIM therapy's ability to drive a substantial and sustained reduction in 24-hour ambulatory systolic blood pressure, the gold standard, and most accurate measure of hypertension. Seeing substantial sustained ambulatory blood pressure reductions in patients treated with AVIM therapy for over three and a half years on average reinforces our confidence in the potential of this novel therapy to have a clinically meaningful and long-lasting beneficial effect on hypertensive pacemaker patients."
Reduction in aSBP measured at 6 months from randomization and therapy activation was the primary endpoint of the MODERATO II study, a European multi-center, double-blind, randomized pilot study involving 47 subjects. Patients randomized to AVIM therapy and antihypertension medication in that study experienced an 11.1 mmHg (p<0.001) reduction in mean aSBP at 6 months follow-up, resulting in a statistically significant difference of 8.1 mmHg compared to control patients who were managed only with antihypertensive medications (p=0.01).1
Long-term blood pressure results are from a follow-up study of 16 patients originally enrolled in the MODERATO II study. This group included eight patients from the MODERATO II AVIM treatment arm and eight control arm patients that crossed over to AVIM therapy at the end of the 6-month double-blind phase. Each patient's aSBP was measured an average of 3.6 (±0.6) years following original initiation of AVIM therapy. As a group and based on individual paired data, these patients continued to experience a statistically significant, clinically meaningful mean aSBP reduction of 8.9 mmHg, identical to the 8.9 mmHg mean reduction in aSBP seen in this same group of patients at the 6-month primary aSBP measurement endpoint of the original study.
AVIM therapy is an investigational patented bioelectronic therapy, administered using a standard dual-chamber pacemaker, designed to immediately, substantially and persistently reduce blood pressure. Orchestra BioMed and Medtronic plc (NYSE:MDT) ("Medtronic") formed a strategic collaboration for the development and commercialization of AVIM therapy for hypertensive pacemaker patients in July 2022. If AVIM therapy is approved by the U.S. Food and Drug Administration, Medtronic will have exclusive global rights to commercialize AVIM-enabled pacing systems for this target population, and Orchestra BioMed will share in the revenues generated from Medtronic sales of the AVIM-enabled pacing systems.
Orchestra BioMed is actively enrolling patients in the BACKBEAT pivotal study, a global, multi-center, prospective, randomized, double-blind study investigating the efficacy and safety of AVIM therapy in patients who have recently undergone implantation of a Medtronic dual-chamber cardiac pacemaker and have uncontrolled hypertension despite the use of antihypertensive medications. The study's primary efficacy endpoint will determine at three months post-randomization whether AVIM-treated patients experience a statistically significant reduction in aSBP as compared to control patients.

About Hypertension and the Risk of High Blood Pressure in the Pacemaker Population
Hypertension ("HTN") is characterized by elevated blood pressure which increases the force of blood pushing against blood vessels, requiring the heart to work harder and consume more oxygen. HTN accelerates the progression of atherosclerosis and leads to increased risk of major cardiac events like heart attack, heart failure, kidney disease and other end organ damage. HTN is the leading global risk factor for death, affecting an estimated 1.28 billion adults worldwide. In the United States, 122 million adults, or approximately 47% of all adults, are estimated to have HTN. While many patients do not notice high blood pressure, cardiovascular risk doubles for every 10-mmHg increase in systolic blood pressure and the mortality rate doubles with an increase of 20 mmHg in systolic blood pressure.2
It is estimated that more than 70% of the approximately 1.1 million people globally who are implanted with cardiac pacemakers each year are also diagnosed with HTN. Based on updated American College of Cardiology/American Heart Association guidelines, an even higher percentage (approximately 80%) of U.S. patients that are indicated for the implant of a pacemaker have HTN. Pacemaker patients tend to be elderly and are more likely to suffer from co-morbidities such as atherosclerosis, hyperlipidemia, diabetes mellitus and chronic kidney disease, and harder to treat effectively with medical therapy for many reasons including co-morbidities and a high prevalence of isolated systolic HTN.
About AVIM Therapy (BackBeat CNT™)
AVIM therapy, also known as BackBeat CNT™, 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. The global IDE pivotal BACKBEAT (BradycArdia paCemaKer with atrioventricular interval modulation for Blood prEssure treAtmenT) study will further evaluate the safety and efficacy of AVIM therapy in lowering blood pressure in a similar target population of patients who have been indicated for, and recently implanted with, a dual-chamber cardiac pacemaker.
