Colorectal Neoplasms Clinical Trial
Official title:
A Phase II Multicenter Study of Erbitux (Cetuximab) in Patients With Refractory, EGFR-Negative Metastatic Colorectal Carcinoma
This is a phase II, multicenter, open-label study of cetuximab in patients with epidermal
growth factor receptor (EGFR) negative, metastatic colorectal carcinoma who have progressed
after receiving at least one standard chemotherapeutic regimen that included a
fluoropyrimidine. Target enrollment is 80 evaluable patients.
Patients with EGFR-negative metastatic colorectal carcinoma who have progressed after
receiving at least one standard chemotherapeutic regimen that included a fluoropyrimidine,
will receive an initial dose of cetuximab, 400 mg/m2 , intravenously (i.v.) over 120
minutes, followed by weekly treatment with cetuximab, 250 mg/m2 i.v. over 60 minutes.
Patients who experience unacceptable toxicity or who have progressive disease (PD) will not
receive further cetuximab therapy.
Patients will be evaluated for a tumor response at a minimum of every 6 weeks while on
cetuximab therapy. Patients with stable disease (SD), partial response (PR), or a complete
response (CR) may continue to receive weekly cetuximab therapy, unless they are dose-delayed
or discontinued because of toxicity. Patients who have a PR or CR must have a confirmatory
tumor assessment no less than 4 weeks after the initial evaluation demonstrating a response.
To evaluate the objective response rate, a single-stage design will be used in this study.
