Description

PRIMARY OBJECTIVE:

I. To identify the maximum tolerated dose (MTD) for cryodevitalization cycle duration.

OUTLINE: This is a dose-escalation study.

Patients undergo 3 freeze-thaw cycles of cryodevitalization over 30 seconds or 3, 5, or 7 minutes each during standard of care robotic bronchoscopy with biopsy on study. Patients then undergo standard of care surgical resection on study. Patients also undergo a chest radiography (x-ray) on study as well as computed tomography (CT) and tissue sample collection throughout the study.

After completion of study treatment, patients are followed up at 3 and 7 days and are then followed as clinically required per standard of care for 24 months.
