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.

Serum creatinine < 2.0 mg/dL
The patient must be able to comprehend and have signed the informed consent
The patient must have documentation of their date of laryngotracheal stenosis diagnosis and prior medical/surgical history
Participants must have also had a prior suspension microlaryngoscopy with endoscopic excision of scar and balloon dilation procedure prior to study entry

Exclusion Criteria

Use of corticosteroids (glucocorticoids) within 7 days of everolimus administration (except physiologic dose equivalent)

Current use of cytochrome P450 3A inhibitors (such as azole antifungals, nondihydropyridine calcium channel blockers, some macrolide antibiotics, grapefruit) can result in significant interactions
Baseline proteinuria as defined by urine dipstick analysis
History of angioedema
Baseline/continued use of drugs known to be associated with angioedema including angiotensin converting enzyme inhibitors
Significant pulmonary disease independent of laryngotracheal stenosis as defined by and FEV1/FVC < 10% of the expected value for the patient's age
Evidence of a COVID-19 infection including anosmia, upper respiratory symptoms or positive test result within the 30 days prior of trial participation
Patients who are not fully vaccinated for COVID 19 for at least 4 weeks prior to study entry
Immunosuppressive therapy within previous 21 days or expected need for immunosuppressive therapy for the duration of the study
Known immunodeficiency
