A Multicenter Phase II Randomized Trial Of Immunotherapy Versus Chemotherapy Guided By Circulating Tumor DNA-Based Molecular Response On Patients With Metastatic NSCLC

Subjects will be randomized 2:1 and patients in both arms will begin treatment with nivolumab 360 mg intravenously every 3 weeks and ipilimumab 1 mg/kg intravenously every 6 weeks. At five weeks of treatment, subjects will have ctDNA response evaluation with Guardant360 Response assay. At the next cycle of treatment (+/- 2 days), patients in the larger arm will receive treatment based on the Guardant360 Response assay results, as described below. Subjects will undergo ctDNA evaluation with Guardant360 Response assay 6- week post-randomization and at the time of progression. Response to therapy…
