Orchestra BioMed Holdings, Inc. announced the presentation of new data demonstrating the long-term effect of atrioventricular interval modulation therapy on generating clinically-meaningful reductions in 24-hour ambulatory systolic blood pressure 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. 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). 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 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.
