Brief summary:
The purpose of this study is to investigate the safety of zalutumumab in combination with radiotherapy as the treatment of patients with head and neck cancer who are not eligible for platinum based chemotherapy.

Detailed description:
This is an open label, multi-center, phase I/II dose-escalation clinical trial investigating the safety of zalutumumab in combination with radiotherapy. The safety of zalutumumab doses in combination with radiotherapy (RT) will be investigated using 3 patient cohorts in a dose-escalation / de-escalation design based on Dose Limiting Toxicity (DLT). The dose-escalation starts at 8 mg/kg zalutumumab in combination with RT. Initially, three patients will be treated at a dose level and observed for DLTs. If none of the three patients experience a DLT, then the next cohort of three patients is treated at the next higher dose of zalutumumab. If one of three patients treated at a dose level experience a DLT, then three more patients are treated at the same dose level. If two or more of the three patients experience DLTs, then the next cohort of three patients should be treated at the next lower dose of zalutumumab, unless at least six patients on that dose have already been dosed. Furthermore, if 1 or fewer DLTs are observed among six patients at a given dose level, then the next cohort of three patients is treated at the next higher dose of zalutumumab. The maximum tolerated dose will be decided by Genmab based on the recommendations made by the IDMC on the basis of their review of the aggregated safety data.

Arms:
arm 1: Zalutumumab in combination with radiotherapy for 8 weeks. The treatment period of 8 weeks is followed by a 3 week follow-up period where all adverse events are collected and then additionally a 2 year follow-up period where only serious adverse events are collected. arm 2: Zalutumumab in combination with radiotherapy for 8 weeks. The treatment period of 8 weeks is followed by a 3 week follow-up period where all adverse events are collected and then additionally a 2 year follow-up period where only serious adverse events are collected.

Interventions: intervention 1: Zalutumumab
Intervention descriptions: intervention 1: Eight weekly infusions
