A phase II study of capecitabine, oxaliplatin, and cetuximab with or without bevacizumab as frontline therapy for metastatic colorectal cancer. A Fox Chase extramural research study.

ABSTRACT:

Objectives

Dual inhibition of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) demonstrated initial promise in clinical trials. This phase II study tested the efficacy and safety of capecitabine, oxaliplatin, and cetuximab with or without bevacizumab as first-line treatment for metastatic colorectal cancer patients.

Methods

Patients were randomized to receive capecitabine 850 mg/m2 PO twice daily for 14 days, oxaliplatin 130 mg/ m2 IV day 1, and cetuximab 400 mg/m2 IV loading dose followed by 250 mg/m2 IV days 1, 8, and 15 with (arm A) or without (Arm B) bevacizumab 7.5 mg/kg IV day 1 every 21 days. Tumor samples were collected and retrospectively analyzed for KRAS mutation status. The primary endpoint was response rate, with time to prog
