Combined Zephyr Valve System With Inter-lobar Fissure Completion for Lung Volume Reduction in Emphysema
United States20 participantsStarted 2021-08-01
Plain-language summary
The purpose of this protocol is to perform a pilot prospective randomized controlled clinical trial to evaluate the potential role of lung fissure completion strategy (experimental intervention) in addition to endobronchial valve (EBV) placement (representing "standard-of-care") in select patients with severe COPD/emphysema and with evidence for \<95% fissure completion between adjacent lung lobes. In select patients, lung fissure completion strategy will be performed by either video-assisted thorascopic surgery (VATS)-guided or robotic-guided stapling along the lung fissures in an attempt to reduce collateral ventilation and determine whether or not this experimental strategy will improve outcome following subsequent EBV placement. EBV placement will follow successful VATS-guided or robotic-guided fissure stapling.
The study will enroll approximately 20 patients at BIDMC, and outcomes will focus on procedure-related complications, physiological measurements (ex., FEV1 by pulmonary function testing) and clinical symptoms (i.e., questionnaires). Patient will be followed for 3-month period, receiving usual standard of care during the 3 months of follow-up. The goal of this protocol is to determine if elimination of significant collateral lung ventilation between lung lobes is possible, and whether such strategy to eliminate collateral lung ventilation between lobes improves outcomes following subsequent EBV placement (i.e. promotes atelectasis of diseased lung segments) in the management of severe COPD/emphysema in appropriate candidates. For subjects in the medical management control group, upon completion of the 3-month F/U period, they will be eligible for EBV if they choose.

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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
