Inter-lobar Fissure Completion in Patients With Failed Bronchoscopic Lung Volume Reduction
(SAVED-1)
What this study is about
The purpose of this protocol is to perform a pilot forward-looking controlled clinical trial to evaluate the potential role of lung fissure completion with pleural adhesiolysis strategy (experimental intervention) in severe emphysema/COPD patients with failed bronchoscopic lung volume reduction (BLVR) via the use of endobronchial valves (EBVs) therapy.
View original scientific description
The purpose of this protocol is to perform a pilot prospective controlled clinical trial to evaluate the potential role of lung fissure completion with pleural adhesiolysis strategy (experimental intervention) in severe emphysema/COPD patients with failed bronchoscopic lung volume reduction (BLVR) via the use of endobronchial valves (EBVs) therapy. In select patients, the lung fissure completion with adhesiolysis strategy will be performed by video-assisted thoracoscopic surgery (VATS) guided stapling along the lung fissures to reduce collateral ventilation with adhesions removal and determine whether this experimental strategy will improve outcomes after failed BLVR in patients with severe emphysema/COPD.

- Nonsmoking for 4 months prior to screening and willing to not smoke during the study duration.
- Current pneumococcus vaccination.
- Current influenza vaccination.
- Target lung volume reduction \<350ml after bronchoscopic lung volume reduction (BLVR).
- Persistent dyspnea defined as an mMRC score greater or equal to 2 after bronchoscopic lung volume reduction (BLVR).
- Endobronchial valves (EBV) are still in place.
- Willing and able to complete protocol required study follow-up assessments and procedures.
Exclusion criteria
- Clinically significant (greater than 4 tablespoons per day) mucus production.
- Myocardial infarction within 6 months of screening.
- Decompensated heart failure.
- Three or more pneumonia episodes in last year.

- Prior lung transplant, LVRS, bullectomy, or lobectomy.
- Clinically significant bronchiectasis.
- Unable to safely discontinue anticoagulants or platelet activity inhibitors for 7 days.
- Uncontrolled pulmonary hypertension (systolic pulmonary arterial pressure \>45mmHg) or evidence or history of CorPulmonale as determined by a recent echocardiogram (completed within the last 3 months prior to screening visit).
- Left ventricular ejection fraction (LVEF) less than 40% as determined by a recent echocardiogram (completed within the last 3 months prior to screening visit).
- Resting bradycardia (\<50 bpm), Complex ventricular arrhythmia, sustained SVT.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
