Summary

This trial tests a special pacemaker called the BackBeat Moderato that can adjust its pacing to help control high blood pressure. Researchers will turn the device on and off for short periods in 28 people who already have the pacemaker implanted, measuring how their blood pressure changes. The goal is to see if the device can safely lower systolic blood pressure when active.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
BackBeat Moderato device (programmable hypertension control via pacemaker)
What this could lead to
If it works, this could offer a new way to manage high blood pressure using a pacemaker, potentially reducing the need for daily pills.
What could go wrong
This is a small, early-phase study with only 28 participants, so results may not apply to everyone. The device requires implantation, which carries surgical risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subject is implanted with a Moderato® implantable pulse generator (IPG) and is being followed by the site per standard of care. * Subject has an average office systolic blood pressure \> 130 mmHg and \< 170 mmHg at the sub-study screening visit. Exclusion Criteria: * Subject has permanent atrial fibrillation. * Subject had significant paroxysmal atrial fibrillation/flutter burden (defined as \>25% of beats) in the past month. Atrial fibrillation/flutter burden will be determined by interrogation of the Moderato pulse generator. * Subject experienced neurological events (stroke or TIA) within the past year. Subject have had a serious adverse event classified as related to CNT or the Backbeat Moderato device. * Female subject who is pregnant, breast-feeding, intends to become pregnant or has the possibility of becoming pregnant during the conduct of the study and is not willing to use contraception during the study. * Subject cannot or is unwilling to provide informed consent.
