Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Other design features
This study is a pilot investigation of the feasibility of using measurement of serum 5-HIAA as a surrogate clinical marker for the antivascular activity of voltaren in patients with colorectal cancer. This study will also investigate if increases in 5 HIAA are observed in healthy controls following a dose of voltren, and whether chemotherapeutic agents also induce a rise.
