This randomized phase II/III trial studies how well radiation therapy works with durvalumab or cetuximab in treating patients with stage III-IVB head and neck cancer who cannot take cisplatin. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Monoclonal antibodies, such as durvalumab and cetuximab, may interfere with the ability of tumor cells to grow and spread. It is not known if radiation therapy with durvalumab will work better than the usual therapy of radiation therapy with cetuximab in treating patients with head and neck cancer.
Lead-In: To determine the safety of radiotherapy (RT) with concurrent and adjuvant anti-PD-L1 therapy [MEDI4736 (durvalumab)] is safe in patients with locoregionally advanced head and neck cancer (HNC) who have a contraindication to cisplatin. Phase II: To test the hypothesis that concurrent RT and anti-PD-L1 therapy improves PFS compared to standard therapy (RT with concurrent cetuximab) in patients with locoregionally advanced HNC who have a contraindication to cisplatin. Phase III: To test the hypothesis that concurrent RT and anti-PD-L1 therapy improves overall survival compared to standard therapy (RT with concurrent cetuximab) in patients with locoregionally advanced HNC who have a contraindication to cisplatin.
Active Comparator: Cetuximab + Radiation Therapy Patients receive cetuximab IV weekly over 60-120 minutes. Treatment repeats every week for up to 8 courses in the absence of disease progression or unacceptable toxicity. Beginning 5-7 days after first cetuximab dose, patients undergo IMRT 5 fractions per week for up to 7 weeks. Experimental: Durvalumab + Radiation Therapy Patients receive durvalumab IV over 60 minutes every 4 weeks. Treatment repeats every 4 weeks for up to 7 courses in the absence of disease progression or unacceptable toxicity. Beginning week 2, patients undergo IMRT 5 fractions per week for up to 7 weeks.
