Trial Information

A Pilot Clinical Trial of Preoperative Cetuximab With Concurrent Continuous Infusion Fluorouracil and Pelvic Radiation in Patients With Local-Regionally Advanced Rectal Cancer


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.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Histologically confirmed rectal adenocarcinoma meeting 1 of the following staging
criteria:

- Locally advanced disease

- Resectable (uT3) disease

- Primary gross transmural tumor that is not adherent to adjacent pelvic
structures by endorectal ultrasound

- Primary tethered or unresectable (cT4 or uT4) disease

- Primary tumor is contiguous with or adherent or fixed to adjacent
pelvic structures by clinical exam and CT scan

- Primary surgery would likely leave residual tumor

- Small volume extrapelvic metastases allowed

- Recurrent disease after definitive resection

- Disease limited to the pelvis

- Requires combined modality treatment

- Epidermal growth factor receptor status-positive, -negative, or -unknown

- If previously treated with adjuvant fluorouracil-based chemotherapy, no disease
recurrence during or within 12 months after completion of adjuvant therapy
