| Scientific title | A pilot study of the administration of curcumin to determine colonic curcumin tissue levels in patients awaiting colorectal endoscopy or patients with colorectal cancer awaiting resection |
| Study acronym | CTAAC Pilot of curcumin |
| Study objectives | To assess colorectal tissue levels of curcumin in individuals who have taken 1.8 g of curcumin daily for 14 days. Patients are either from the National Colorectal Cancer Screening Programme or from those waiting resection of colorectal cancer. |
| Ethics approval(s) | NRES, Northern & Yorkshire Research Ethics Committee, 29/11/2007, ref: 07/MRE03/31 |
| Health condition(s) or problem(s) studied | Colorectal cancer |
| Intervention | 1. Endoscopy but only as part of routine screening under the National Colorectal Cancer Screening Programme 2. Resection of colorectal cancer by surgery All patients will receive curcumin 1.8 g daily as tablets for 14 days prior to endoscopy. Patients will be contacted once, 7 days after completing curcumin, to ensure that no late effects have occurred. |
| Intervention type | Drug |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Curcumin |
| Primary outcome measure(s) |
From 30 eligible patients who are compliant in taking all doses have tissue measurement of curcumin greater than or equal to 5 nMol/g tissue, assessed approximately two months after completion of the trial when the colon biopsies will be assayed in the laboratories for curcumin levels. The exact timing of assay will vary depending on the number of samples which will be batched together for assessment. |
| Key secondary outcome measure(s) |
To assess the practicality, acceptability and safety of individuals taking 5 capsules of curcumin (2.25 g total daily dose of curcuminoids, 1.8 g curcumin) daily for 14 days, assessed at 3 weeks from entry to the study. |
| Completion date | 31/12/2011 |
