Clinical trials can evaluate medicines, procedures, medical devices, and other health treatments. They are divided into different stages, called phases. The earlier phase trials look at whether an intervention is safe and effective, whilst later phase trials aim to test whether new treatments are better than existing treatments.
Within South West Sydney we primarily conduct Phase II and Phase III trials.
Phase I clinical trials test a new drug or intervention for the first time, in a small group of people. The aim is to evaluate how safe the medicine is, how it works, and how well tolerated it is. These trials are generally very short, and have a high degree of supervision.
Phase II trials are conducted on a small group of people have a specific medical condition. The aim is to assess whether the intervention is safe and effective. These trials are also closely supervised.
Phase III trials generally involve many thousands of people from around the world. The aim is to show that the intervention is safe and effective for the treatment of a specific medical condition. These trials are monitored both locally and at an international level.
Phase IV These trials are done after the drug or intervention is approved by the Therapeutic Goods Administration (TGA). The aim of these trials is to obtain further information about the drug or intervention in widespread clinical practice.
