What is this study?

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.

It is , overseen by an independent and licensed medical staff.

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.

Who this study is looking for

In plain language, from the study's own rules. The study team confirms the full details with you — this isn't a final yes or no.

✅ You may be able to join if…

  • Age 40 to 75 years.
  • COPD/emphysema that is stable on less than 10 mg prednisone (or equivalent) per day.
  • Not smoking for 4 months before screening and willing to not smoke during the study.
  • Finished supervised pulmonary rehabilitation within the last 12 months (or doing regular maintenance rehab if the first supervised program was more than 12 months ago).
  • Able to complete required follow-up visits and procedures.

🚫 You may not be able to join if…

  • More than 95% fissure completion on HRCT or negative collateral ventilation on StratX/Chartis evaluation.
  • More than 4 tablespoons per day of clinically significant mucus production.
  • Heart problems that are not stable, including a myocardial infarction within 6 months, uncontrolled congestive heart failure, or uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure >45 mmHg) or CorPulmonale history.
  • Too many recent lung flare-ups/infections (three or more pneumonia episodes or three or more COPD exacerbation episodes in the last year).
  • Certain past lung procedures or conditions, including prior lung transplant, LVRS, bullectomy, or lobectomy, or clinically significant bronchiectasis.

Are you a good fit?

Simplified highlights. The study team always confirms the full details with you.

  • Adults roughly 40–75
  • !Some conditions may not be a fit: Heart / cardiovascular disease, High blood pressure, COPD (chronic lung disease)

What to expect, step by step

  1. 1

    Usually a few weeks

    The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.

  2. 2

    Treatment

    If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.

  3. 3

    Follow-up

    After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.

Has this treatment been tested before?

What you need to know before you apply

What is this study testing?+

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.

Is it safe? Who makes sure of that?+

This is a research study. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.

Will I get a placebo instead of the real treatment?+

Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.

Do I have to stop taking my current medications?+

It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.

Does it cost anything? Will I be paid?+

Study-related care is provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.

Do I need insurance? Will anyone ask about my immigration status?+

No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.

What if English isn't my first language?+

You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.

Is my information private?+

Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
