Pembrolizumab, Cisplatin, and Intensity Modulated Radiation Therapy in Treating Patients with Previously Untreated Stage III-IVb Head and Neck Cancer

Trial Status: Active

This randomized phase II trial studies how well pembrolizumab works when given during or after cisplatin and intensity modulated radiation therapy in treating patients with previously untreated stage III-IVb head and neck cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. It is not yet known whether giving pembrolizumab during or after cisplatin and intensity modulated radiation therapy will kill more tumor cells.

PRIMARY OBJECTIVE:

I. To evaluate two schedules of fixed-dose pembrolizumab (concurrent versus [vs.] sequential) added to standard, concurrent cisplatin-intensity modulated radiotherapy (IMRT) in patients with previously untreated locally advanced (PULA) head and neck squamous cell carcinoma (HNSCC), in order to recommend the schedule to be tested in a subsequent definitive, randomized study.

SECONDARY OBJECTIVE:

I. To evaluate the toxicity of two sequences of the combination of pembrolizumab and concurrent cisplatin-IMRT in patients with PULA HNSCC.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I (SEQUENTIAL): Patients receive cisplatin intravenously (IV) over 60 minutes and undergo IMRT once weekly in weeks 1-7. Beginning 2 weeks after cisplatin and IMRT, patients receive pembrolizumab IV over 30 minutes every 3 weeks in weeks 9, 12, 15, 18, 21, 24, 25, and 30.

ARM II (CONCURRENT): Patients receive pembrolizumab IV over 30 minutes in weeks -1, 3, 6, 9, 12, 15, 18, and 21. Patients receive cisplatin over 60 minutes IV and undergo IMRT as in Arm 1.

After completion of study treatment, every 3 months for 21 months, every 6 months for 1 year, than annually for 2 years.
