Additional data from APPRAISE ATP trial reinforce modular therapy approach with EMBLEM™ Subcutaneous Implantable Defibrillator and EMPOWER™ Leadless Pacemaker

MARLBOROUGH, Mass., May 18, 2024 /PRNewswire/ — Boston Scientific Corporation (NYSE: NYSE:) today announced positive six-month results from the ongoing pivotal MODULAR ATP clinical trial of the mCRM™ System, the first modular cardiac rhythm management (CRM) system that consists of the EMBLEM™ Subcutaneous Implantable Defibrillator (S-ICD) System and the EMPOWER™ Leadless Pacemaker (LP). As components of the mCRM System, the devices are designed to work together wirelessly to coordinate painless intracardiac anti-tachycardia pacing (ATP) therapy, provide rate-responsive bradycardia pacing support and to prevent sudden cardiac death without the risk of leads in the heart or under the sternum. Findings were presented at Heart Rhythm 2024, the annual meeting of the Heart Rhythm Society, and simultaneously published in The New England Journal of Medicine.

In addition to evaluating the safety and performance of the EMPOWER LP as a standalone pacemaker, the trial evaluated the ability of the EMBLEM S-ICD System to successfully communicate a wireless request to the LP to deliver ATP therapy. Findings from the trial met all pre-specified six-month safety and effectiveness endpoints, and demonstrated:

  • A major complication-free rate of 97.5% after implantation of the EMPOWER LP.1
  • A communication success rate of 98.8% from the EMBLEM S-ICD System to the EMPOWER LP.2
  • An ATP success rate of 61.3%,3 and no patient requests for deactivation of ATP or bradycardia pacing due to pain or discomfort.
  • Pacing capture thresholds, which indicate stable device fixation within the heart, of ‰¤ 2.0 V at 0.4 ms in 97.4% of patients.

“We saw excellent overall clinical performance of the mCRM System in this study, including a high rate of communication success from the S-ICD to the leadless pacemaker, and a low rate of major leadless pacemaker complications,” said Prof. Reinoud Knops, M.D., Ph.D., Department of Cardiology and Electrophysiology, Amsterdam UMC, Amsterdam, Netherlands. “These findings are noteworthy, as high percentages of communication success and pain-free termination of spontaneous arrhythmia episodes indicate a potential upgrade pathway for patients currently implanted with an S-ICD who develop a need for ATP or pacing.”

Also presented at Heart Rhythm 2024 were results from the APPRAISE ATP clinical trial “ a prospective, randomized, multicenter study evaluating ATP as a primary strategy for terminating ventricular tachycardias in primary prevention (PP) patients (i.e., those without a history of spontaneous sustained ventricular arrhythmias). The trial enrolled 2,626 PP patients indicated to receive an ICD at 134 centers globally and is the largest head-to-head trial of ATP in this patient group. In the study, patients were randomized 1:1 to standard transvenous-ICD therapy “ ATP plus an ICD-delivered shock to terminate a ventricular tachycardia “ versus shock only. Across five years of follow up, data demonstrated a statistically significant, but small absolute first all-cause shock reduction in only 1% of patients per year. Shock burden, or the number of shocks experienced by a patient, was not significantly different between the two arms, and the vast majority of patients in the ATP-plus-shock arm did not require ATP therapy.

“Together, data from the MODULAR ATP and APPRAISE ATP trials reinforce the promise of the groundbreaking mCRM System, illustrating a clear path forward for physicians to offer therapies that prevent sudden cardiac death and deliver ATP for the small number of patients who benefit from it,” said Kenneth Stein, M.D., senior vice president and global chief medical officer, Boston Scientific. “Instead of subjecting all patients to the risks of more invasive approaches, such as placing leads in the heart or tunneling them under the sternum to provide therapies they might not require, these data indicate physicians may have the opportunity to tailor therapy to the patient’s individual needs and health.”

The company anticipates U.S. Food and Drug Administration approval of the mCRM System in 2025. For more information on the mCRM System and MODULAR ATP trial, visit www.bostonscientific.com/mcrm. To learn more about the EMBLEM MRI S-ICD System, visit www.sicdsystem.com.

1 Major complications defined as any complication related to the EMPOWER LP or its implantation procedure that results in system revision, permanent loss of LP function, hospitalization, or death.
2 During communication tests, the S-ICD attempted to command the LP to deliver pacing at a rate approximately 10 beats per minute faster than the patient’s intrinsic rhythm.
3 ATP success rate defined as terminating ventricular arrhythmia.
