COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

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

Outcomes
Primary outcome [1] 670 0
The primary aim of this exploratory study is to determine whether advanced cancer results in a decreased functional activity of CYP2C19, independent of genotype, as assessed by metabolism of a single dose of omeprazole
Timepoint [1] 670 0
At 2 hours post administration
Secondary outcome [1] 1377 0
To determine whether decreased CYP2C19 function correlates with markers of disease severity as determined by circulating inflammatory cytokines (IL1, IL6 & TNF-α) and a marker of acute phase response, C-reactive protein.
Timepoint [1] 1377 0
