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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
The lysosomal storage disorders (LSDs) are monogenic disorders associated with inflammation affecting multiple organs, and early death. Few treatments are available that can modify the disease course, and there is an urgent need to identify new steps in pathogenesis that can be targeted therapeutically. The complement system is novel and highly plausible as a primary driver of inflammation and cellular injury in the LSDs. This study assesses the complement activation state in patients with Fabry disease (FD), Gaucher disease (GD) and Niemann-Pick disease, type C (NPC), with comparison to healthy controls. This has the potential for immense clinical benefit through targeted complement inhibition across the full spectrum of lysosomal storage disorders, in which key pathophysiological processes including the inflammatory response to lysosomally 'stored' materials are shared.
