Brief Summary
The OXYGEN-RCT trial is a randomized, controlled, double blinded, prospective, multi-center trial to demonstrate the safety and efficacy in adult benign central airway stenosis. Participates will be i...
Detailed Description
Subjects will complete follow-up post-treatment at 30 days, 3 months, 6 months, 12 months, and every 6 months after through the primary endpoint, with a minimum of 2 years at study end.
Eligibility Criteria
Inclusion
- Age ≥ 22 years.
- Symptomatic de-novo or restenotic benign central airway stenosis in the subglottis, trachea, or mainstem bronchi with at least 50% narrowing, as determined by CT or bronchoscopy.
- In the opinion of the investigator, subject can undergo laryngoscopy/bronchoscopy under general anesthesia and has a central airway stenosis amenable to balloon dilation.
- For idiopathic subglottic stenoses, either de-novo or a dilation interval equal to or less than 18 months.
- Target benign stenosis etiologies including:
- Post-intubation stenosis,
- Idiopathic subglottic stenosis,
- Post-transplantation stenosis,
- Non-malignant trachea-bronchial stenosis
- Willing and able to complete protocol required follow-up visits.
- Willing and able to provide written informed consent.
Exclusion
- Two or more clinically significant (e.g. non-traversable) stenoses with total length \>5cm or unable to be treated with a single balloon 2. Female subjects who are pregnant or breastfeeding or plan to become pregnant in next 12 months 3. Subject currently has a stent at target stenosis location or has had a stent at the target location within the past 90 days.
- 4\. Subject has existing tracheostomy or had a tracheostomy within past 90 days 5. Contraindication to laryngoscopy/bronchoscopy, anesthesia, or deep sedation 6. Planned tracheal resection in the next 90 days. 7. Dynamic etiology of benign stenosis such as excessive dynamic airway collapse, tracheobronchomalacia, or stenosis due to external compression, or past tracheostomy which requires stent placement or surgical referral 8. Inclusion of vocal cord in target stenosis 9. Known medically significant unresolved lower respiratory tract infection, such as pneumonia, fungus, tuberculosis, etc.unrelated to stenosis 10. Target stenosis is beyond the mainstem bronchi 11. Signs or suspicion of a malignant airway obstruction NOTE: If obstruction is suspicious for malignancy based on clinical or laryngoscopic/bronchoscopic presentation, malignancy must be excluded by biopsy prior to randomization 12. Severe coagulation disorders or current use of anticoagulant or antiplatelet medication that cannot be safely managed per recommended guidelines prior to the index procedure 13. Chronic steroid use exceeding more than 10 mg per day for any medical condition including immunosuppression post-lung transplant or autoimmune associated airway suppression.
- 14\. Received local steroid or chemotherapeutic treatments into target stenosis in the last 12 weeks or planned treatment during index or staged study procedure.
- 15\. Planned serial intralesional steroid injections (SILSIs) post index procedure.
- 16\. Stenosis not amenable to laryngoscopic/bronchoscopic dilation in the opinion of the investigator 17. Acute condition that requires emergent procedure prior to screening assessment 18. Concurrent medical condition that would affect the investigator's ability to evaluate the patient's condition or could compromise patient safety, such as recent myocardial infarction, severe pulmonary disease, bleeding diathesis, large thoracic aneurysm, pharyngeal or cervical deformity, ongoing infection, etc 19. Subject has known fistula between tracheobronchial tree and esophagus, mediastinum to pleural space.
- 20\. Subject has vasculitis that is not well controlled in the opinion of the investigator.
- 21\. Diagnosed with a disease requiring chemotherapy (e.g. cancer). 22. Allergy to paclitaxel or structurally related compounds 23. Target stenosis is within a transplanted lung or transplant anastomosis, or a tracheal resection anastomosis, which has been transplanted or resected within the last 60 days.
- 24\. Target stenosis is related to radiation therapy 25. Subject has a life expectancy of less than 2 years. 26. Current participation in another pre-market drug or medical device clinical study that has not reached its primary endpoint.
