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.
Tamoxifen is an important drug for the treatment of breast cancer. Used adjuvantly after operation in early breast cancer, tamoxifen reduces annual recurrence rate by half and cancer death by one third. Used preventatively it also reduces the risk of breast cancer by 50% in women at high risk for developing the disease Tamoxifen needs to be activated in the body to an active form called endoxifen, mainly by the enzyme called CYP2D6. Patients have variable capability to activate tamoxifen due to variable function of this enzyme. Studies showed clear correlation of specific genetic variant of CYP2D6 with endoxifen blood levels. It is estimated that up to 25% Caucasian population have reduced or even absent CYP2D6 function. More recently, there were studies that showed the correlation with genetic variant of CYP2D6 and breast cancer relapse in early breast cancer patients treated with tamoxifen. Food and Drug Authority (FDA) in America and recommended checking CYP2D6 genotype in patients receiving tamoxifen treatment, but they did not specify how to interpret the genotype results and what kind actions to take in patient with adverse genotype. The aim of the investigators study is to see if increasing tamoxifen in patients with genetic polymorphism of CYP2D6 will increase endoxifen level to the same range of most patients who have wild type (normal functional)CYP2D6.
Endometrial cancer usually begins in the endometrium, which is the tissue lining of the uterus. Endometrial cancer is the most commonly diagnosed gynaecological malignancy in Australia. It affects 1 in 80 Australian women and there are about 1400 new cases and 260 deaths from the disease every year. Most affected women are aged between 50 and 70 years. The purpose of this study is to investigate the possible role of the endocrine system in the regulation of human endometrial cancer. By looking at the laboratory results of people with endometrial cancer and also those without endometrial cancer we hope to gain a better understanding of how endometrial cancer develops and progresses. This may lead to the development of new, effective therapies for endometrial cancer.
The purpose of this study is to determine if LY2189265 is effective in reducing hemoglobin A1c (HbA1c) and safe, as compared to Insulin Glargine in participants with Type 2 Diabetes. Participants must also be taking metformin and glimepiride.
The primary objective of this study is to evaluate the efficacy and safety of once daily (QD) versus twice daily (BID) dosing of eliglustat tartrate (Genz-112638) in patients with Gaucher disease type 1 who have demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638). The secondary objective is to evaluate the pharmacokinetics (PK) of Genz-99067 when eliglustat tartrate (Genz-112638) is administered QD and BID in patients with Gaucher disease type 1 who have demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638).
GAND-emesis is a multinational, randomized, double-blind, placebo-controlled, parallel-group study to investigate the efficacy and tolerability of a neurokinin1 receptor antagonist (fosaprepitant dimeglumine) in combination with an antiemetic (anti-nausea-and-vomiting) control regimen (palonosetron and dexamethasone) in patients with a gynaecological cancer diagnosis, who are scheduled to receive radiotherapy and weekly chemotherapy. The study aims at investigating if a three-drug antiemetic regimen is superior to a two-drug regimen (standard treatment) in preventing nausea and vomiting in patients receiving radiotherapy and weekly chemotherapy. A pilot study demonstrated that approximately 50% of patients will experience nausea and vomiting when offered a two-drug antiemetic regimen, and it is expected that addition of a third drug (a neurokinin1 receptor antagonist) can increase the proportion of patients with no vomiting in the course of combined chemo-radiotherapy.
The purpose of this study is to compare the effect of azacitidine (Vidaza) to conventional care regimens on overall survival in elderly AML patients.
The primary objective of this study is to assess the effect of treatment with bendamustine on cardiac repolarization as reflected by the rate-corrected QT interval by the Fridericia method (QTcF).
The primary objective of the study is to determine whether armodafinil treatment, at a dosage of 150 mg/day, is more effective than placebo treatment as adjunctive therapy to mood stabilizers for treatment of adults with major depression associated with bipolar I disorder.
This was an open-label, dose escalation study to investigate the safety, pharmacokinetics, pharmacodynamics and clinical activity of GSK2118436 and GSK1120212 in combination. This study was designed in four parts. In Part A, the effect of repeat doses of GSK1120212 on the pharmacokinetics of single dose GSK2118436 was investigated prior to evaluating combination regimens. In Part B, the range of tolerated dose combinations was identified using a dose-escalation procedure. In Part C, different dose combinations of GSK2118436 and GSK1120212 were evaluated, based on results from the dose escalation cohorts. In Part D, the pharmacokinetics and safety of GSK2118436 administered as HPMC capsules alone and in combination with GSK1120212 was evaluated.
This is an extension study designed to assess the safety and durability of platelet count increases with romiplostim treatment of thrombocytopenic patients with immune (Idiopathic) thrombocytopenia purpura. This study is available to pediatric patients who have completed a previous romiplostim ITP study and meet the eligibility criteria of this study.
