Everolimus Trial in Laryngotracheal Stenosis
Study Details
Study Description
Brief Summary
Subglottic stenosis (obstructing scar in the larynx and trachea) occurs in patients spontaneously (idiopathic), with autoimmune disease, and after long-term breathing tube placement and can result in communication disability and high mortality rates due to the obstructed airway. The proposed Adjuvant EveRolimus Outcomes (AERO) trial is proof-of-concept study using the immunosuppressant drug, everolimus, to reduce the number of surgeries for patients with idiopathic Subglottic Stenosis (iSGS). Success with the AERO trial will allow for everolimus to be used in subsequent larger trials of participants with laryngotracheal stenosis and could lead to everolimus being the first FDA approved medical treatment for iSGS.

Change in Peak Expiratory flow (L/min) in patients with Laryngotracheal Stenosis will be assessed.
Secondary Outcome Measures
- Dilation interval (time between surgery) [Up to 2 years]
Dilation interval (time between surgery) in months will be assessed.
