A Randomized Phase II/III Trial of De-Intensified Radiation Therapy for Patients With Early-Stage, P16-Positive, Non-Smoking Associated Oropharyngeal Cancer
In Brief
A Phase 2 clinical trial evaluating Biopsy Procedure, Biospecimen Collection, and 10 other interventions for Basaloid Squamous Cell Carcinoma and 7 related conditions. Active but no longer recruiting, targeting 384 participants across 494 sites in 2 countries.

Detailed Summary
This phase II/III trial studies how well a reduced dose of radiation therapy works with nivolumab compared to cisplatin in treating patients with human papillomavirus (HPV)-positive oropharyngeal cancer that is early in its growth and may not have spread to other parts of the body (early-stage), and is not associated with smoking. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, 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. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial is being done to see if a reduced dose of radiation therapy and nivolumab works as well as standard dose radiation therapy and cisplatin in treating patients with oropharyngeal cancer.

Timeline
Arms & Interventions
Patients undergo standard dose RT as 70 Gy IMRT or IGRT over 6 fractions per week and receive 100 mg/m\^2/day cisplatin IV over 30-60 minutes on days 1 and 22. Treatment continues for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients receive FDG and undergo PET/CT or CT during screening and during follow up, and undergo MRI during follow up. Patients may also undergo tissue biopsy and blood sample collection throughout the study.
Patients undergo reduced dose RT as 60 Gy IMRT or IGRT QD over 5 fractions per week and receive 100 mg/m\^2/day cisplatin IV over 30-60 minutes on days 1 and 22. Treatment continues for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients receive FDG and undergo PET/CT or CT during screening and during follow up, and undergo MRI during follow up. Patients may also undergo tissue biopsy and blood sample collection throughout the study.
Beginning 1 week prior to radiation, patients receive 240 mg fixed dose nivolumab IV over 30 minutes on day 1. Treatment repeats every 2 weeks (14 days) for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo reduced dose RT as 60 Gy IMRT or IGRT over 6 fractions per week for 5 weeks in the absence of disease progression or unacceptable toxicity. Patients receive FDG and undergo PET/CT or CT during screening and during follow up, and undergo MRI during follow up. Patients may also undergo tissue biopsy and blood sample collection throughout the study.
