The Men's Health Study

Currently Recruiting

Brisbane, Australia

This study aims to evaluate a new medication being developed for erectile dysfunction (ED). 

Erectile dysfunction (ED) is a common condition where a man cannot get or keep an erection firm enough for sexual activity. It can affect confidence, relationships, and overall quality of life, and may be caused by physical, hormonal, or psychological factors. While medications are approved for use which improve blood flow and are widely used, they do not work for everyone.  

The study drug combines sildenafil (commonly known as Viagra®) with cabergoline, which acts on brain and hormone pathways. It aims to improve effectiveness especially for those who do not respond well to current treatments while potentially reducing side effects.

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.
