Study Summary
This trial is a prospective, single center, interventional study evaluating the safety and efficacy of SCT in patients with BCAS.
Who is the study for?
This trial is for adults over 18 with significant tracheal stenosis, which means their airway passage is narrowed by at least half. They should be referred for endoscopic treatment of suspected benign tracheal stenosis and able to consent. It's not for those with malignant stenosis, recent multiple treatments, oxygen needs above a certain level, severe lung conditions like COPD or asthma, unstable blood pressure or heart rate, cartilage issues needing surgery or a history of complications from cryotherapy.Check my eligibility
What is being tested?
The CryoStasis trial tests spray cryotherapy (SCT), where liquid nitrogen treats the airways versus standard care involving radial incisions and balloon dilation. The goal is to see if SCT can better maintain open airways after six months compared to current methods. This study will provide more solid evidence on whether SCT leads to longer-lasting improvements in patients with non-cancerous narrowing of the breathing tubes.See study design
What are the potential side effects?
While specific side effects are not listed here, procedures like balloon dilation and radial incision can cause bleeding, infection or recurrence of narrowing. Spray cryotherapy may have similar risks along with potential cold-related damage to healthy tissues around the treatment area.

Who else is applying?
What site did they apply to?
Vanderbilt University Medical Center
What portion of applicants met pre-screening criteria?
Did not meet criteria
Why did patients apply to this trial?
I am looking to see if there are alternatives to the dilation surgery. My condition is stable since it was diagnosed in March of 2022. However, it is only a matter of time before surgery will be needed. I know the surgery is ongoing and that many people have had multiple surgeries every year. I am looking for a less invasive and/or better treatment option.
