Trial Description

start of 1:1-Block title


An Open-label, Single Arm, Phase II Trial to Investigate the Safety and Efficacy of Sym004 in Patients With Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck (SCCHN) Who Have Failed Anti-EGFR Monoclonal Antibody-based Therapy

Brief Summary in Lay Language

The trial is designed as a multi-centre, open label phase II trial that investigates the
efficacy and safety of Sym004 in patients with squamous cell cancer of the head and neck

Patients included must have responded to previous anti-EGFR monoclonal antibody-based
therapy and subsequently become resistant to that therapy.

It is believed that Sym004 has the potential to induce tumor responses and provide a
superior treatment option to patients with advanced SCCHN.

Secondary Outcome

- Adverse Events
- Objective Tumor Response
- Biomarkers; Tumor and skin biopsies are assessed for inhibition of EGFR and downstream intermediates.
Optional biomarker study will investigate associations between biological parameters and clinical features such as disease symptoms, drug response or potential adverse events.
