Study information

Scientific title

A phase I/II study of Radiotherapy, Irinotecan, Capecitabine then Excision for locally advanced rectal cancer



Study hypothesis

Phase I/II study. Phase I investigated the safety of preoperative neoadjuvant chemoradiation using radiotherapy combined with concurrent capecitabine and irinotecan for locally advanced rectal cancer before surgery, determining the recommended dose.

Phase II of the study then used the recommended dose to assess the histological downstaging efficacy of this chemoradiation regimen, together with assessment of long-term survival end points and late radiation morbidity.

Ethics approval

First MREC approved on the 18th March 2004 (ref: 04/4/015)

2. Male or female patients aged greater than or equal to 18 years old
3. World Health Organization (WHO) performance status 0, 1 or 2
4. Histologically confirmed previously-untreated carcinoma of the rectum with distal extent within 12 cm of the anal verge using a rigid sigmoidoscope
5. Deemed to be a candidate for preoperative downstaging chemoradiation due to: T3 disease on magnetic resonance imaging (MRI) scanning with disease less than or equal to 2 mm from the edge of the mesorectum or T4 disease on MRI scanning or any T3/T4 disease on MRI scanning with the distal extent of tumour less than or equal to 5 cm from the the anal margin

7. Adequate renal and hepatic function: serum creatinine = 1.5 x upper limit of normal (ULN), serum bilirubin = 1.25 x ULN, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase = 2.5 x ULN

Age group




Target number of participants

Planned sample size: 142; UK sample size: 142

Participant exclusion criteria

1. Previous systemic chemotherapy
2. Previous radiotherapy to the planned exposure area
3. Those unfit for resection because of metastases
4. Any severe concurrent medical condition which would make it undesirable, in the clinician's opinion, for the patient to participate in the trial or which would jeopardise compliance with the trial protocol
5. Patients with a calculated creatinine clearance of less than 50 ml/min
6. Patients with loss of continuity of the upper gastrointestinal (GI) tract or malabsorbtion
7. Patients who have suffered a myocardial infarction within last year and/or have unstable angina, arrythmia or cardiac failure
8. Pregnancy or lactation. Patients of child bearing potential not implementing adequate contraception.
9. Previous or current malignancies at other sites, with the exception of adequately treated in situ carcinoma of the cervix uteri and basal or squamous cell carcinoma of the skin
10. Subjects considered by the investigator to be at risk of transmitting any infection through blood or other body fluid including Acquired Immune Deficiency Syndrome (AIDS), or other sexually transmitted disease or hepatitis
11. Patient participation in other studies
12. Partial or complete bowel obstruction (though patients in whom this has been relieved with a defunctioning stoma, are permitted to enter the trial)
