Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on the use of the patient's natural defences, immunotherapy mobilizes the immune system to recognize and destroy cancer cells, and it has revolutionized the treatment of lung cancer.

However, the effectiveness of immunotherapy varies from patient to patient. At present, we have no weak markers to predict with certainty the efficacy of immunotherapy treatment in a given individual.

Current scientific data identifies a number of molecules produced by the cancer cells and their environment which can be detected by various means (blood tests, breath analysis, etc.).

The aim of this study is to understand whether the amount of nitric oxide (NO) present in the breath is a more accurate predictor of response to immunotherapy.

Participation in this study involves breath testing (to measure FeNO (Fractional exhaled Nitric Oxide)) before receiving the first infusion of immunotherapy, and at the follow-up visit after the 4th course of immunotherapy.
