Microwave probe aims to clear cancer-blocked airways, but study halted early
NCT ID NCT06105606
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new microwave device used through a thin tube to destroy tumors blocking the main airways in people with lung cancer. Only 3 patients were enrolled before the study was stopped. The goal was to see if the device could safely and effectively open the airway.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients age between 18 and 80 years of age and able to provide informed consent. * Candidate for bronchoscopy under general anesthesia. * Diagnosis of central airway obstruction (trachea, right main stem bronchus, left main stem bronchus), as evidenced by CT or CT/PET imaging confirmed or suspected to be due to malignant etiology, for which the bronchoscopist has deemed that endoscopic ablation/debridement is indicated (i.e. endobronchial tumors, mixed endobronchial/extrinsic compression lesions). Exclusion Criteria: * Patients who are unable to understand the informed consent, including potential risks and benefits of the procedure. * Patients in whom bronchoscopy under general anesthesia is contraindicated. * Any comorbidity that the investigator feels would interfere with the safety of the subject or the evaluation of study objectives * Pacemaker, implantable cardioverter, or another electronic implantable device * Patients with coagulopathy * Patients in other therapeutic lung cancer studies * COVID-19 positive patient at the time of the procedure. * Patients who are pregnant * Patients with purely extrinsic compression of the airway.
