Spray Freezing for Non-Cancerous Airway Narrowing
Part of Lungs & breathing clinical trials.
This trial is testing a treatment called spray cryotherapy, which uses extreme cold to open up a narrowed airway. It may help people with non-cancerous (benign) narrowing of the windpipe or voice box area that is causing symptoms like trouble breathing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a narrowing in your windpipe or voice box area that is not caused by cancer and is causing symptoms.
- The narrowed part of your airway is less than 1 centimeter wide.
- Your airway narrowing is simple (not complicated) and does not involve damaged cartilage.
- You do not have other serious lung conditions like large air pockets, a hole between your windpipe and food pipe, or active cancer in your windpipe.
- You are not pregnant.

This trial tests a freezing spray (cryospray) to treat narrowing of the windpipe (trachea) that is not caused by cancer. It may be an option if you need a procedure to open your airway.
This trial uses a freezing technique (cryoablation) through a bronchoscope to shrink tumors blocking the main airways. It is combined with standard chemotherapy and immunotherapy (pembrolizumab) to treat advanced lung cancer that hasn't been treated before.
This trial studies genetic changes in people with tracheal stenosis (narrowing of the windpipe). It compares two treatments: wedge resection (cutting out the narrow part) and radial incision (cutting to open it up). This may help doctors choose the best treatment in the future.
This trial tests a cold-treatment procedure (cryotherapy) to treat a stubborn cough caused by nerve signaling (not infections or common allergy/acid problems). It may help people whose cough has lasted at least 8 weeks and who have already tried to rule out other causes.
This study tests a new way to freeze and destroy small lung tumors using a thin tube with a camera (bronchoscope) to guide the freezing probe. It is for people with early-stage lung cancer or limited lung metastases who cannot or prefer not to have surgery or radiation.
This study tests a freezing technique called cryoablation for people with small lung tumors (3 cm or less) who cannot have surgery or standard treatments. The procedure is done through a bronchoscope, a thin tube passed through the mouth into the lungs.
