Study information

Scientific title



Study hypothesis

To evaluate the improvement in pathological complete response rate from the addition of cetuximab to neoadjuvant oxaliplatin and capecitabine followed by synchronous chemoradiation and Total Mesorectal Excision (TME) in patients with Magnetic Resonance Imaging (MRI) defined high risk rectal cancer.

Ethics approval

Rectal cancer


Group one: receiving oxaliplatin (Eloxatin), capecitabine (Xeloda) and pre-operative radiotherapy with cetuximab followed by TME.
Group two: receiving oxaliplatin (Eloxatin), capecitabine (Xeloda) and pre-operative radiotherapy without cetuximab followed by TME.

Intervention type



Phase II

Drug names

Oxaliplatin, capecitabine, cetuximab.

Primary outcome measures

Pathological complete response at TME.

Secondary outcome measures

1. Radiological response rates after neoadjuvant chemotherapy and after completion of all neoadjuvant chemoradiotherapy
2. Complete resection rate (R0 resection) with microscopic clear resection margin (tumour observed more than 1 mm from the resection margin), especially circumferential resection margin
3. Perioperative measures including operation time, duration of in-patient stay, peri-operative transfusion requirement and mortality within 30 days of operation
4. Post-operative complications including wound infection, wound dehiscence fistula formation
5. Quality of TME as graded by audit of photographed surgical specimens
6. Rate of Abdomino-Peritoneal Excision (APE)
7. Rate of permanent defunctioning colostomies
8. Clinical and radiological anastomotic leak rate
9. Progression free survival and patterns of failure
10. Overall survival
11. Safety
13. Quality of life including long term bowel function
13. Evaluation of molecular and genetic predictors of response to anti-Epidermal Growth Factor Receptor (anti-EGFR) treatment
14. Evaluation of gene expression changes which occur in response to treatment with cetuximab, and to correlate these changes with response to treatment and prognosis.

Participant inclusion criteria

1. Aged 18 years or over
2. Histological diagnosis of adeno- or undifferentiated non-small cell carcinoma of rectum
3. High risk operable rectal cancer as defined by the presence on MRI of at least one of the following:
a. tumours within 1 mm of mesorectal fascia i.e. circumferential resection margin threatened or involved
b. T3 tumours at/below levators
c. tumours extending into more than or equal to 5 mm into peri-rectal fat
d. T4 tumours (including the involvement of bladder or vagina if surgical resection is possible with clear margins)
e. presence of extra-mural venous invasion (primary tumour is therefore at least T3)
4. World Health Organisation (WHO) performance status of zero to two
5. No evidence of metastatic disease as determined by Computerised Tomography (CT) scan of chest and abdomen or other investigations such as Positron Emission Tomography (PET) scan or biopsy if required
6. Adequate bone marrow function with platelets more than 100 x 10^9/l, White Blood Cells (WBC) more than 3 x 10^9/l and neutrophils more than 1.5 x 10^9/l
7. Serum bilirubin less than 1.5 x Upper Limit of institutional Normal range (ULN) and transaminases less than 2.5 x ULN
8. Serum creatinine less than ULN or calculated creatinine clearance more than 50 ml/min
9. No concurrent uncontrolled medical condition
10. No active malignant disease other than non-melanotic skin cancer or carcinoma in situ of the uterine cervix in the last ten years
11. Life expectancy of more than three months
12. Adequate contraceptive precautions if relevant
13. Informed written consent

Target number of participants


Participant exclusion criteria

1. Any contraindications to MRI (e.g. patients with pacemakers)
2. Medical or psychiatric conditions that compromise the patient’s ability to give informed consent
3. Patients with rectal cancer which is deemed inoperable at diagnosis should not be entered into the study even if they are potentially operable if their primary is successfully downstaged by neoadjuvant treatment. This includes patients with locally advanced inoperable disease, such as tumour extending beyond the mesorectal fascia into pelvic side wall structures, or situations where surgical resection with clear margins is unlikely to be possible
4. T1-2 rectal cancer at any level
5. Presence of metastatic disease or recurrent rectal tumour
6. Concurrent uncontrolled medical conditions
7. Any previous chemotherapy or radiotherapy, and any investigational treatment for rectal cancer
8. Pregnancy or breast feeding
9. Patients with known malabsorption syndromes or a lack of physical integrity of the upper gastrointestinal tract
10. Clinically significant (i.e. active) cardiac disease (e.g. congestive heart failure, symptomatic coronary artery disease and cardiac dysrhythmia, e.g. atrial fibrillation, even if controlled with medication) or myocardial infarction within the last 12 months
11. Patients with any symptoms or history of peripheral neuropathy
