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.
The main purpose of this study is to investigate whether bosentan (Tracleer®) affects the wall thickness of the pulmonary arteries in patients with idiopathic pulmonary arterial hypertension (iPAH) and PAH related to systemic sclerosis (PAH-SSc). The second purpose is to investigate if bosentan affects the enlargement of small vessels in the lungs in response to natural chemicals in patients with iPAH and PAH-SSc.
Alzheimer's disease (AD) is a fatal degenerative disease of the brain for which there is no cure. AD causes brain cells to die. AD is thought to be caused by an excess of beta-amyloid (β-amyloid), a sticky protein in the brain that forms amyloid plaques. At autopsy, AD patients are required to have these amyloid plaques in the brain in order to have a definitive diagnosis of AD. Inhibiting the enzyme gamma-secretase (γ-secretase) lowers the production of β-amyloid. Semagacestat (LY450139) is a functional γ-secretase inhibitor and was shown to lower β-amyloid in blood and spinal fluid in humans tested thus far and in blood, spinal fluid, and brain in animals tested thus far. This study used several different tests to measure the effect of semagacestat on both β-amyloid and amyloid plaques for some participants. The build-up of amyloid plaques was measured by a brain scan that takes a picture of amyloid plaques in the brain. Other tests measured the overall function of the brain and brain size in some participants. In this trial, participants who initially received placebo (inactive sugar pill) were, at a certain point in the study, switched over to active drug, semagacestat. In other words, all participants could eventually receive active drug. Participation could last approximately 2 years. Participants taking approved AD medications were permitted to participate in this study and continue taking these medications during the study. All participants who completed this study had the option to continue receiving semagacestat by participating in an open-label study. Preliminary results from this study (H6L-MC-LFAN [LFAN]) and another similar study (H6L-MC-LFBC [LFBC; NCT00762411]) showed semagacestat did not slow disease progression and was associated with worsening of clinical measures of cognition and the ability to perform activities of daily living. Study drug was stopped in all studies. Studies LFAN, LFBC, and open-label H6L-MC-LFBF (LFBF; NCT01035138) were amended to continue collecting safety data, including cognitive scores, for at least 7 months. The Clinical Trial Registry (CTR) will reflect results of analyses from the original LFAN protocol in addition to those from the amended LFAN protocol.
This study will follow ,morbidly obese subjects as they undertake weight loss before and after laparoscopic gastric banding, examining markers of glucose and lipid metabolism, adipokines and measures of body fat.
DMD/BMD is a genetic disorder that develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability during childhood and teenage years. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of DMD/BMD in approximately 13 percent (%) of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 2b trial that will evaluate the clinical benefit of ataluren in boys with DMD/BMD due to a nonsense mutation. The main goals of the study are to understand whether ataluren can improve walking, activity, muscle function, and strength and whether the drug can safely be given for a long period of time.
This phase-II trial will investigate the efficacy, safety and the tolerability of a sequential therapy consisting of 4 courses of single agent rituximab followed by 4 courses of R-CHOP chemotherapy in patients with CD20+ posttransplant lymphoproliferative disorders (PTLD). However, responders to rituximab achieving a CR after the first 4 applications of rituximab will go on with rituximab monotherapy and will not receive chemotherapy.
The purpose of this study is to show that doripenem is as effective as imipenem-cilastatin in the treatment of patients with ventilator-associated pneumonia.
PF-02341066 may work in cancer by blocking the cell growth, migration and invasion of tumor cells. PF-02341066 is a new class of drugs called c-Met/Hepatocyte growth factor receptor tyrosine kinase inhibitors. This compound is also an inhibitor of the anaplastic lymphoma kinase (called ALK) tyrosine kinase and ROS receptor tyrosine kinases. This research study is the first time PF-02341066 will be given to people. PF-02341066 is taken by mouth daily.
The objective is to evaluate whether once weekly subcutaneous (SC) injection of idrabiotaparinux is at least as efficient to prevent clots in brain and in the other organs than oral international normalized ratio (INR) adjusted-dose warfarin in patients with atrial fibrillation (AF).

The purpose of this study is to assess the effect of rimonabant treatment on the histological features of NASH in patients with Type 2 diabetes.
