The System Study

Currently Recruiting

6 Jul 2026

Up to $5,350

Brisbane, Australia

Inflammatory and autoimmune conditions are disorders where the immune system becomes overactive and causes ongoing inflammation in the body. This happens because certain immune signals stay switched on for longer than they should. One of the key proteins involved in this process is called IRAK4, which normally helps the body respond to infection. In these conditions, IRAK4 sends too many inflammatory signals, leading to persistent inflammation that can affect the skin, joints, or other parts of the body. This study aims to test the safety and tolerability of a potential new oral treatment for these conditions.

While these are considered unlikely, you will be carefully monitored throughout the study and provided with prompt treatment if any such effects occur. 

Before joining, you’ll receive detailed information about the study, meet with a doctor, and have the chance to ask any questions.
