Study Title

Effect of Prolonged Nightly Fasting (PNF) on Immunotherapy Treatment Outcomes in Patients with Advanced Head and Neck Cancer (HNSCC)-Role of Gut Microbiome


The purpose of this study is to determine if Prolonged nightly fast (PNF) /Time restricted eating leads to improved responses to ICB in patients with metastatic head and neck cancer.


Primary objective; Aim 1: Evaluate compliance to PNF in metastatic head and neck cancer patients, measured at 3 months. This is a pilot study in preparation of a larger RCT. The RCT will be considered feasible if our pilot study has >75 % retention rate of participants through the first 3 months. Aim 2: To evaluate dynamic changes in gut microbiome composition/diversity as well as gut microbial metabolites in patients on PNF and controls and corelate with response to ICB therapy. Response will be measured by objective response rate (ORR) of ICB using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 at 3 months
