There are about 10460 clinical studies being (or have been) conducted in Australia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This project will examine whether short-term (over a 12-hour period) pharmacological lowering of the stress hormone 'cortisol' improves the nervous system response to food intake in overweight or obese individuals who have metabolic syndrome. The investigators know from our previous research that overweight/obese persons who are insulin resistant, have a blunted sympathetic nervous response to carbohydrate ingestion. This means that they are less able to dissipate energy from caloric intake, which would favour the maintenance of the obese state. Cortisol adversely impacts on insulin action and transport into the brain and cortisol levels are often elevated in persons with central (abdominal) obesity. A randomized, double-blind, placebo controlled, cross-over design will be used to compare the effects of overnight treatment with metyrapone (15 mg/kg at midnight and 15 mg/kg at 6 am) versus placebo on sympathetic nervous system activity in response to a standard 75-g oral sugar (glucose) tolerance test. A 2 week washout will separate treatments. Metyrapone is a drug that reversibly inhibits the enzyme 11beta-hydroxylase, and therefore the production of cortisol. It is used clinically to test the activity of the adrenal gland (the key site of cortisol production) and the pituitary gland. The investigators anticipate that at the dosage used, it will lower blood cortisol concentration by 44 to 64% during the experimental morning. The study protocol comprises two screening visits and two experimental mornings. Key procedures will include: - Assessment of insulin action (sensitivity) using the gold standard 'clamp' method. - Measurement of sympathetic nervous system activity by both biochemical methods (isotope dilution which provides a measure of the apparent rate of release of 'noradrenaline'-the key neurotransmitter in the sympathetic nervous system) and direct intra-neuronal nerve recordings from the peroneal nerve in the lower leg. - Indirect calorimetry to assess resting metabolic rate and the response to sugar ingestion. - DEXA scan to quantify fat and lean mass. - Assessment of arterial elasticity and calf blood flow by non-invasive methods. - A standard 75g oral sugar tolerance test. The results will provide important new information regarding the role of cortisol on nervous system function in overweight/obese individuals.
To determine the dose or doses of PF-00547659 that will be the most effective to improve or halt the disease symptoms in patients with moderate to severe ulcerative colitis.
The aim of this extension trial is to assess the long-term safety of BIBF 1120 treatment in patients with Idiopathic Pulmonary Fibrosis who have completed one year treatment and the follow up period in the double-blind phase III placebo controlled parent trials (1199.32 and 1199.34), who wish to continue treatment with BIBF 1120.
The purpose of this study is to confirm the efficacy and safety of perampanel compared to placebo in patients with refractory partial-onset seizures
To assess whether adding LCL161 to weekly paclitaxel enhances the efficacy of paclitaxel in women with triple negative breast cancer whose tumors are positive for a defined pattern of gene expression
The purpose of this trial is to assess the safety profile of Cvac for epithelial ovarian cancer patients who were enrolled in the Cvac clinical trial CAN-003 and are no longer eligible for study participation due to disease progression.
The investigators hypothesise that testosterone therapy will synergize with dietary intervention to achieve weight loss. Obese men will receive diet, and be randomised to either testosterone therapy or placebo. Primary outcomes will be weight and body composition.
The purpose of this study is to determine if 24 weeks of treatment with Pegylated Interferon Lambda plus Ribavirin and 12 weeks of treatment with Pegylated Interferon Lambda plus Ribavirin and Daclatasvir will be safe and effective for treatment of hepatitis C compared to 24 weeks of treatment with Pegylated Interferon Alfa-2a plus Ribavirin
