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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Description of intervention(s) / exposure
National prospective observation study/registry of patients identified with a severe cutaneous adverse reaction (SCAR).
Participants will be identified by site investigators as having SCAR. Identified patients meeting inclusion/exclusion criteria will be consented to one or more of - (i) access the medical record for clinical data, (ii) 12 month follow up questionnaire, (iii) saliva for DNA biobanking [single sample], (iv) blood test [single sample] for peripheral blood mononuclear cell (PBMC) storage, (v) skin biopsy of acute exanthema [applicable to only some sites for separate study - stub study with same researchers]. Patients followed until 12 months post SCAR onset.

Statistical methods / analysis
Where the data distribution conforms to a Gaussian distribution the mean will be compared using paired students t-tests. Where the data does not conform, the non-parametric Mann-Whitney U test will be used to assess differences. Chi square test or Fisher’s exact test will be used to assess differences in categorical data.

Summary
Brief summary
The development of a national clinical and DNA registry, AUS-SCAR, of SCAR patients with severe T cell-mediated drug hypersensitivities will allow investigators to (i) perform surveillance for new and emerging drug causality, (ii) develop clinical prediction rules, (iii) understand best-practice treatment approaches, (iv) discover genomic predictors that prevent SCAR onset and (v) improve long-term outcomes and medication safety.
