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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

* Travelled to or lived (2 weeks or more) in a malaria-endemic country during the past 12 months or planned travel to a malaria-endemic country during the course of the study.
* Has evidence of increased cardiovascular disease risk (defined as greater than 10%, 5 year risk)
