PATCHVALVE: Endobronchial Valves Plus Blood Patch for Persistent Air Leaks
What this study is about
The goal of this study is to evaluate the real-world safety and effectiveness of combining endobronchial valve (IBV) placement with endobronchial blood patching (EBP) for the treatment of persistent air leaks (PALs) in adult patients undergoing bronchoscopy. PALs are a challenging condition often associated with prolonged hospital stays, increased morbidity, and delayed recovery.
View original scientific description
The goal of this study is to evaluate the real-world safety and effectiveness of combining endobronchial valve (IBV) placement with endobronchial blood patching (EBP) for the treatment of persistent air leaks (PALs) in adult patients undergoing bronchoscopy. PALs are a challenging condition often associated with prolonged hospital stays, increased morbidity, and delayed recovery. The main questions this study aims to answer are: * Does the combination of endobronchial valve placement and endobronchial blood patching accelerate resolution of persistent air leaks? * What are the procedural outcomes, complications, and hospital-related metrics (e.g., chest tube duration, length of stay, and readmission rates) associated with this technique? Participants will: * Undergo standard-of-care bronchoscopy with identification of air leak source. * Receive intrabronchial instillation of autologous blood and tranexamic acid (TXA) followed by balloon occlusion and endobronchial valve placement. * Be followed for resolution of air leak and post-procedure outcomes through standard inpatient monitoring and data collection.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Adult (≥18 years) patients who have been diagnosed with persistent air leaks (PALs) due to conditions such as alveolar-pleural fistulas following pulmonary resections, traumatic injury, or underlying lung disease or other cause.
- PAL patients who are deemed non-candidates for surgical intervention or have declined surgery. {
Exclusion criteria
- Patients who have received other experimental or investigational treatments for PALs that could confound the results.
- Patients with contraindications to undergoing bronchoscopy, such as severe cardiovascular instability, or those who cannot tolerate the procedure due to other medical reasons.
- Bronchopleural fistula
Where
- Boston, Massachusetts
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.
