About this study

Background: Non-small cell lung cancer (NSCLC) can be hard to treat and is often fatal. People with NSCLC commonly have changes in the bacteria that populate their lungs. These bacterial changes may aid tumor growth. Researchers want to find out if treating the bacteria, too, can help cancer treatment work better. Objective: To test 2 inhaled antibiotics (aztreonam and vancomycin), combined with a standard cancer treatment, in people with NSCLC. Eligibility: People aged 18 years and older with NSCLC that has returned or progressed after treatment and cannot be treated with surgery. Design: Participants will be screened. They will have a physical exam with blood tests. They may blow into a machine to test how well their lungs work. They will have imaging scans. They may need to have a small piece of tissue cut from their tumor (biopsy). Participants will be treated in six 21-day cycles. They will visit the clinic to receive a drug for cancer treatment on the first day of each cycle. This drug will be administered through a tube attached to a needle inserted into a vein in the arm. The 2 antibiotic drugs will be in the form of a fine mist that can be inhaled. Participants use a device to take these drugs at home. They will inhale aztreonam up to 3 times a day and vancomycin 1 or 2 times a day. They will take these drugs during only 3 of the treatment cycles. Biopsies and other tests will be repeated halfway through and after the study treatment. Follow-up visits will…
