The Linden Study

Currently Recruiting

6 May to 13 May 2026

Up to $2,900

Brisbane, Australia

The study drug is being developed as a potential treatment to support people living with obesity and assist with weight management. While current treatments can be effective, they do not work well for everyone and may cause side effects such as nausea, vomiting, and other gastrointestinal symptoms.

This investigational treatment is designed to offer a different approach. Rather than focusing solely on overall weight reduction, it aims to help regulate appetite while supporting a healthier balance between fat mass and lean muscle mass. By targeting body composition as well as weight, the study drug may provide an alternative option for individuals who have not responded well to existing treatments.

Join our clinical trial

This is a first-in-human (FIH) study, meaning it is the first time the potential treatment is being tested in people. The study has been carefully designed with strict safety protocols and has been approved by an independent ethics committee. It is not known whether the study drug may cause unexpected, serious, or life-threatening side effects. 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.
