About this study

This phase Ib trial tests the safety, side effects and how well losartan, pembrolizumab and stereotactic body radiation therapy (SBRT) for the treatment of patients with head and neck squamous cell carcinoma that has come back to nearby tissue or lymph node after a period of improvement (locally recurrent), that has not responded to previous treatment (refractory) or that has spread from where it first started to multiple other placed in the body (oligometastatic). Losartan is a drug used to treat high blood pressure that may enhance the effects of other cancer treatments such as immunotherapy and radiation. Immunotherapy with pembrolizumab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Giving losartan, pembrolizumab and SBRT may work better in treating patients with locally recurrent, refractory or oligometastatic head and neck squamous cell carcinoma.
