Chronic Evaluation of Respicardia Therapy

Plain-language summary
The purpose of this study is to determine the chronic safety and efficacy of phrenic nerve stimulation on central sleep apnea (CSA). Clinically, CSA events translate into sleep fragmentation, excessive daytime sleepiness, reduced exercise capacity, and possibly ventricular arrhythmias.
The study is chronic in nature, such that subjects will undergo the implantation of an implantable pulse generator and stimulation lead. A sensing lead may also be placed during the initial implant procedure. Subjects will be followed for up to six-months on therapy to assess respiratory and heart failure outcomes. Following the six-month therapy visit, subjects will enter into a long-term follow-up phase until the completion of the study.
It is anticipated that data obtained in this study will show that the proposed intervention can modify respiration with a low incidence of adverse effects. The results of this trial are intended to be used to develop a subsequent protocol for pivotal study.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Candidate is at least 18 years old

* Apnea-Hypopnea Index (AHI) greater than or equal to 20 events/hr
* Predominantly central origin (central apnea events comprise 50% or more of all apnea events)
* Limited obstructive events (obstructive apneas comprise less than 20% of the AHI)
Exclusion Criteria:
* Candidates who are pregnant
* Candidates with baseline oxygen saturation less than or equal to 90% on a stable FiO2
* Candidates with severe COPD

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
