Holdsworth House clinical trials has participated in research since Sydney medical centre was founded, and the semi-autonomous research unit has grown to become one of Sydney's most ambitious and comprehensive. Holdsworth House clinical trials has participated in almost every major national and international HIV clinical trial conducted during the past few years, and is one of Australia's largest recruiter for HIV treatment studies.

The research unit has participated in over 50 studies, and is constantly supervising the progress of between 20 to 30 trials at any time. The number of participants for each trial ranges from 5 to over 200. Such studies include investigating new drugs used to treat HIV, sociological and epidemiological research and many aspects of sexual health as well as other areas such as hypertension and Diabetes. Health research is a continuous process and as such, Holdsworth House medical centre is always involved in cutting edge research that can benefit its patients.

Most of the trials involve drugs which are in their final testing and marketing stage, and the studies must be approved by an independent ethics committee. The trials are conducted for private pharmaceutical companies, collaborations with hospitals, studies initiated by Holdsworth House medical centre, and trials in collaboration with the National Centre in HIV Epidemiological and Clinical Research; although research trials are not limited to HIV treatments.

Clinical Research

Clinical research is a form of medical science that is generally used to assess the safety and effectiveness of medications, treatment regimens and diagnostic products that may be used for prevention, treatment, diagnosis or for relief of symptoms in a disease. These studies are conducted when the medication or therapy is intended for human use.

Clinical research can be conducted using two methods, interventional and observational. Interventional studies are used to determine the efficacy and safety of new medications or dosages of known therapies, iunder controlled circumstances. Observational studies address health issues in large groups of people or for populations in natural settings.

The Australian government requires medication to be tested to confirm it is safe and effective. It is not until this data has been assessed by the Australian government's Therapeutic Goods Administration (TGA) that new medicines are approved for prescribing by your doctor or hospital and made available for sale at the pharmacy.

In Australia, clinical research must conform to the Ethical Principles of the Declaration of Helsinki and to international Good Clinical Practice guidelines. Before a study can go ahead it needs to be approved by independent ethics committees that operate according the guidelines issued by the National Health and Medical Research Council (NHMRC Guidelines). All of the studies conducted at Holdsworth House medical centre have prior ethical approval and meet GCP guidelines. We are regularly audited to ensure that standards are constantly maintained.
