Bryn Mawr Hospital first site in world to enroll patient and complete protocol in landmark JANUS trial for sleep apnea
Bryn Mawr Hospital, part of Main Line Health’s Lankenau Heart Institute, on August 18, 2020 became the first site in the world to successfully enroll a patient and complete the protocol in JANUS, a landmark clinical trial for sleep apnea. The trial seeks to explore whether transvenous stimulation can improve airway physiology. In this first patient, Sheetal Chandhok, MD, the investigator and implanting physician, was able to demonstrate feasibility in this novel approach for managing sleep apnea.
Sleep apnea---when prolonged pauses in breathing occur during sleep---is a serious health issue for many Americans. An estimated 22 million Americans suffer from some degree of sleep apnea, a condition that causes breathing to abruptly stop and restart during sleep. In addition to poor sleep quality, sleep apnea can lead to high blood pressure, heart failure, atrial fibrillation, stroke and other health issues.
The primary objective of the JANUS trial, sponsored by Respicardia, is to assess acute changes in respiration and airway physiology during sleep. The trial is being conducted in patients with central sleep apnea who are undergoing a Remedé system implant, which uses transvenous stimulation to reduce the periods of the breathing pauses. The JANUS trial is conducted during the implantation of commercially available device called the Remede® System, a diaphragm pacemaker that works to stimulate breathing in the same way that the brain would. The Remede® System was first implanted at Bryn Mawr Hospital by Dr. Sheetal Chandhok, a cardiac electrophysiologist, in January 2019.
“Central sleep apnea occurs when the brain temporarily stops sending signals to the muscles that control our breathing. When that happens, this pacemaker (the Remede® System) sends a signal to the phrenic (diaphragm) nerve to trigger breathing. This prevents the risk of interrupted breathing at night, and currently is the only approved treatment for central sleep apnea,” explains Sheetal Chandhok, MD, an electrophysiologist with Bryn Mawr Medical Specialists Association and a member of Lankenau Heart Institute. “In the JANUS trial we hope to show that an alternative transvenous lead location can affect respiration and airway physiology during a commercial Remedē® System implant procedure”.
Dr. Chandhok is one of three primary investigators for the JANUS trial and was the first clinician in the world to enroll a subject and complete the objective for the trial. “The potential success of JANUS trial may have far-reaching implications for a broader set of sleep apnea patients for whom there are only limited treatments,” he said.
The JANUS trial is currently enrolling subjects who are undergoing transvenous phrenic nerve stimulation for moderate to severe central sleep apnea using the Remedē® System. Participants must be over 18. To learn more about this trial or to enroll, visit clinicaltrials.gov.
