Melbourne, Australia

We’re conducting a clinical trial to evaluate a potential new treatment given as an injection under the skin. It is designed to help people with moderate to severe rheumatoid arthritis (RA)—a chronic autoimmune condition that causes joint pain and inflammation. 

The potential new treatment aims to deliver targeted anti-inflammatory effects while minimizing side effects commonly associated with steroid treatments.

Join our clinical trial

This is a first-in-human study, meaning it’s the first time it is being tested in people. Participants will be helping researchers understand how the drug behaves in the body and assess its safety.

We’re looking to understand: 

  • How the body absorbs and processes the potential treatment. 
  • How well the treatment is tolerated at different dose levels. 
  • Whether the treatment shows promise as a safe and effective treatment for RA. 

 

Why participate?

  • Help advance research into a new treatment option for rheumatoid arthritis. 
  • Contribute to early-stage research that could lead to more targeted therapies with fewer side effects. 
  • Receive close medical monitoring and care throughout the study.
