What this Trial Is About

Radiotherapy for advanced-stage head and neck squamous cell carcinoma (HNSCC) results in an unfavorable 5-year overall survival of 40%, and there is a strong biological rationale for improving outcome by combinatorial treatment with immunotherapy. However, also immunosuppressive effects of radiotherapy have been reported and recently a randomized phase-III trial failed to show any survival benefit following the combination of a PD-L1 inhibitor with chemoradiotherapy. The hypothesis is that the combination of these individually effective treatments failed because of radiation-induced lymphodepletion and that the key therefore lies in reforming conventional radiotherapy, which typically consists of large lymphotoxic radiation fields of 35 fractions. By integrating modern radiobiology and individually established innovative radiotherapy concepts, the patient's immune system could be maximally retained. This will be achieved by 1) increasing the radiation dose per fraction so that the total number of fractions can be reduced (HYpofractionation), 2) by redistributing the radiation dose towards a higher peak dose within the tumor center and a lowered elective-field dose (Dose-redistribution) and 3) by using RAdiotherapy with protons instead of photons (HYDRA). The objectives of this study are to determine the safety of HYDRA with protons and photons by conducting two parallel phase-I trials. HYDRA's efficacy will be compared to standard of care (SOC). The immune effects of HYDRA-protons will be evaluated by longitudinal immune profiling and compared to HYDRA-photons and SOC (with protons and photons). There will be a specific focus on actionable immune targets and their temporal patterns that can be tested in future hypofractionated-immunotherapy combination trials. This trial therefore is an important step towards future personalized immuno-radiotherapy combinations with the ultimate goal to improve survival for patients with HNSCC.
