A Randomized, Phase II Study of Ficlatuzumab with or without Cetuximab in Patients with Cetuximab-Resistant, Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma
This randomized phase II trial studies how well ficlatuzumab with or without cetuximab work in treating patients with head and neck squamous cell carcinoma that has come back or spread to other places in the body and resistant to cetuximab treatment. Monoclonal antibodies, such as ficlatuzumab and cetuximab, may block growth signals that lets a tumor cell survive and reproduce, and helps the immune system recognize and fight head and neck squamous cell carcinoma.
Primary Objective: To assess the efficacy of ficlatuzumab, with or without concurrent cetuximab, in patients with cetuximab-resistant, recurrent/metastatic HNSCC as measured by Progression-Free Survival (PFS). Secondary Objective: To describe toxicity and patient-reported quality of life. - To evaluate response rate and overall survival in both treatment arms. - To evaluate the relationship between clinical outcomes (PFS, RR) and candidate tumoral, genomic, peripheral, and immune biomarkers, including: HGF/cMet, EGFR/EGFR, and EGFR/HER2 dimers; mutations in PIK3CA, PTEN, and HRAS; peripheral serum biomarkers including VeriStrat, HGF, soluble HGF, and IL6; peripheral lymphocyte populations; archived and baseline immune infiltrate.
