Actual date on which the first participant was enrolled.

OBJECTIVES: Primary * Determine the safety profile of neoadjuvant cetuximab, fluorouracil, and pelvic irradiation in patients with locally advanced or locally recurrent rectal cancer. Secondary * Determine the activity of this regimen, in terms of pathological complete response rate, in these patients. OUTLINE: This is a non-randomized, open-label, pilot study. Patients receive cetuximab IV over 1-2 hours on days 1, 8, 15, 22, 29, 36, 43, 50, 57, and 64 and fluorouracil IV continuously on days 1-42. Patients undergo whole-pelvic radiotherapy once daily on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40. Treatment continues in the absence of disease progression or unacceptable toxicity. Approximately 1-3 weeks after completion of study treatment, patients undergo surgical resection followed by adjuvant chemotherapy off-study. Patients are followed for up to 5 years.

Design Details

28 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
