This clinical trial is focused on studying treatments for Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma, a type of cancer that occurs in the head and neck region and has returned or spread to other parts of the body. The study will evaluate the effectiveness and safety of three different treatment approaches: a combination of Pembrolizumab and Epacadostat, Pembrolizumab alone, and a treatment regimen known as the EXTREME regimen. Pembrolizumab, also known by its code name MK-3475, is a medication that helps the immune system fight cancer cells. Epacadostat, with the code name INCB024360, is a drug that may enhance the effects of Pembrolizumab.
The purpose of the study is to assess how well these treatments work in managing the cancer and to monitor their safety. Participants will receive one of the treatments and will be monitored over a period of time to see how their cancer responds. The study will also track any side effects experienced by participants to ensure the treatments are safe. The EXTREME regimen is a combination of chemotherapy drugs, including Cetuximab, Cisplatin, and Fluorouracil, which are commonly used to treat this type of cancer.
Throughout the study, participants will receive regular check-ups and assessments to monitor their health and the progress of their treatment. The study aims to provide valuable information on the best treatment options for patients with this type of cancer, helping to improve future care and outcomes. Participants may receive a placebo, which is a substance with no active medication, as part of the study design to compare the effects of the actual treatments.
