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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Summary
Brief summary
Wegener’s Granulomatosis (WG) and WG-like diseases affect the small/medium sized blood vessels. In Canterbury the prevalence of WG is one of the highest in the world. Despite this, we are reliant on information from the Northern Hemisphere to guide us on outcomes and treatments. Whether there are differences in disease severity, prognostic markers and treatment response between the Northern and Southern Hemispheres is unknown. We wish to undertake an observational study of WG patients in Canterbury to characterise the clinical characteristics, treatments and outcomes and compare them to those in the Northern Hemisphere. In addition we will evaluate whether novel markers in the blood and urine help predict disease relapse. Although WG is a rare condition, the severity, chronicity and treatments have a significant impact on those affected. The ability to better predict disease relapse will potentially avoid exposure to harmful treatments.
