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 phase III trial is studying vincristine, carboplatin, and etoposide to see how well they work compared to observation only in treating patients who have undergone surgery for newly diagnosed retinoblastoma. Drugs used in chemotherapy, such as vincristine, carboplatin, and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, no additional treatment is needed for the tumor until it progresses. In this case, observation may be sufficient.
This phase II trial is studying how well combination chemotherapy, radiation therapy, and/or surgery work in treating patients with high-risk kidney tumors. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
The purpose of this study is to evaluate whether a higher dosage of clopidogrel with aspirin (two doses) will decrease the risk of ischemic complications (cardiac death (CV death), myocardial infarction (MI), stroke) after a percutaneous coronary intervention (PCI).
This is a multicenter, 6 months open label safety extension study for all patients who are willing and eligible to continue from the pivotal, double-blind S308.3.003 trial
This study has two main aims. The first is to assess whether Dexamethasone can increase the number of patients with who respond to Velcade. The second aim of this study is to see whether treating patients with relapsed multiple myeloma with Velcade and Dexamethasone for a longer period of time extends the time that the myeloma is under control.
This is a multicenter, randomized, double blind, parallel group study of 6 months' treatment with SLV308 as monotherapy in patients with early stage PD. An open label safety extension to this study is planned as a separate protocol for patients who are willing and eligible to participate.
The primary objective of this study will be to provide further evidence of the long-term safety and tolerability of levodopa-carbidopa intestinal gel (Duodopa®) over 12-months in participants with advanced Parkinson's disease (PD) and severe motor fluctuations.
The purpose of this study is to compare eritoran tetrasodium and placebo in patients with severe sepsis and to demonstrate a reduction of mortality from all causes.
To evaluate efficacy and safety of pazopanib compared to placebo in patients with locally advanced and/ or metastatic renal cell carcinoma (RCC). Approximately 350-400 eligible patients will be stratified and randomized in a 2:1 ratio to receive either 800 mg pazopanib once daily or matching placebo. The study treatment will continue until patients experience disease progression, unacceptable toxicity or death. Primary objective of the study is to evaluate and compare the two treatment arms for progression-free survival. Principal secondary objective is to evaluate and compare the two treatment arms with respect to overall survival. Other objectives are overall response rate [complete response (CR) + partial response (PR)], rate of CR + PR + 6 months stable disease, and the incidence, severity and causality of adverse events and serious adverse events. Safety and efficacy assessments will be regularly performed on all patients. An Independent Data Monitoring Committee will be established to monitor safety during the course of the study and to evaluate interim efficacy data on overall survival.
Many patients develop kidney failure after cardiac surgery. Although this kidney failure can usually be treated effectively, a longer stay in intensive care is often required. While many patients suffer no long term ill effects after developing post-operative kidney failure, some require long term kidney dialysis. We also know that patients who develop post-operative kidney failure are much more likely to die before they leave hospital. Why some people develop kidney failure after cardiac surgery is not known. However, doctors suspect that the process of cardiopulmonary bypass (where the functions of the heart and lungs are taken over by a machine during the operation, to allow the surgeon to operate) overactivates some of the same mechanisms the body uses to defend itself against severe infection. Many of the cell changes by which severe infection causes kidney failure also occur after cardiopulmonary bypass. One of the main overactive defence mechanisms is the release of highly toxic compounds derived from oxygen - a process called 'oxidative stress'. The investigators believe that sodium bicarbonate might reduce the oxidative stress, which occurs during cardiac surgery, and so prevent or decrease the kidney failure, which occurs in many patients. The investigators hope to give sodium bicarbonate (in similar doses to those used safely for treatment of acidosis) to patients during, and for 24 hours after cardiac surgery, and to compare the effects with patients who have not had sodium bicarbonate. The drug, or a placebo, will be given through the drip, which is present in all cardiac surgery patients. Whether a particular patient receives the drug or placebo will be decided at random, and neither the patient nor the investigators will know which has been given. We will measure kidney function before and after the operation using the standard blood tests. The investigators will also take four 20ml samples of blood, spaced before, during, and after the operation, from the arterial catheter routinely inserted in every patient. This blood would be used to measure oxidative stress, and also some of the proteins inside the blood cells, which are responsible for creating the toxic oxygen compounds. In this way we will discover not only the effect of sodium bicarbonate, but also the mechanism of that effect. Sodium bicarbonate is commonly used to treat metabolic acidosis in severe renal disease, circulatory insufficiency due to shock or severe dehydration and has been shown to be an effective drug in preventing contrast-induced nephropathy. Sodium bicarbonate is considered to be safe in the setting of intensive care treatment and is often used in the treatment of patients with metabolic acidosis without any discernible adverse clinical effects. This is a pilot study. If the drug proves effective in this context, further studies on a larger scale would be required to justify its general use. There will be no extra risk to a patient who participates in the study, and no discomfort other than that normally associated with cardiac surgery. Informed consent will be obtained from the patient prior to the operation by one of the investigators or the ICU research nurse. The clinical care of a patient who does not consent for any reason will not be affected.
