There are about 6915 clinical studies being (or have been) conducted in Austria. 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.
Objective: The objective of this study is to compare the efficacy of duloxetine in the treatment of patients with chronic low back pain with a radicular component to placebo. Study hypothesis: Duloxetine is a new substance now in use for the treatment of neuropathic pain. It has proven its efficacy in diabetic peripheral neuropathy and fibromyalgia in several trials. The investigators therefore hypothesize that duloxetine will be efficacious in patients with chronic low back pain and a radicular component. Study Rationale: Chronic low back pain is an extremely common diagnosis. However, therapeutic options for the condition are limited and therapy remains difficult. Duloxetine has proven its efficacy in patients with neuropathic pain and may also be useful in chronic low back pain. If the investigators are able to show a benefit for patients in the duloxetine arm, the substance may constitute a further treatment alternative in chronic low back pain. Study Design: Prospective, randomized, double-blind placebo-controlled cross over study. Patients will be administered duloxetine for 4 weeks followed by a 2 week wash-out phase after which they will be medicated with placebo for 4 weeks. A second group of patients will receive the medication in reversed order. The primary study endpoint is constituted the weekly mean of VAS-Score in the last week of each treatment period. Secondary endpoints are defined as use of rescue medication, Beck Depression Inventory score, Health related Quality of Life SF-36 score and side effects/adverse events.
The purpose of this study was to find out if in patients with non-exudative age-related macular degeneration (AMD), randomly assigned to cataract surgery, any AMD size progression or progression to exudative AMD could be detected 6 months after surgery.
Endostatin, a 20-kDa cleavage product of collagen XVIII, is a component of the extracellular matrix expressed in the basement membrane. As a potent inhibitor of angiogenesis, endostatin induces endothelial cell apoptosis and diminishes cell migration, adhesion and proliferation. Endostatin may stop the progression of atherosclerosis. Atherosclerotic heart disease involves unwanted tissue growth. By cutting off the blood supply from a plaque the likelihood of plaque rupture may eventually be reduced. Recent data indicates that the loss of collagen XVIII/endostatin is related to the enhancement of neo-vascularization and vascular permeability in atherosclerosis. Plaque neo-vascularization strongly correlates with the regional content of inflammatory cells. Furthermore, increased vascular permeability enhances lipid accumulation in the vessel walls, hence increasing foam cells. Therapeutic angiogenesis is a most promising strategy for the treatment of myocardial infarction. However, it remains unknown if and how endogenous angiogenesis inhibitors, such as endostatin, regulate angiogenesis in myocardial infarction. Rat models showed that after myocardial infarction endostatin neutralization displayed adverse left ventricular remodeling and severe heart failure compared with controls. Although angiogenesis was increased, tissue remodeling and interstitial fibrosis were further exaggerated in post-myocardial infarction hearts by endostatin neutralization. However, several studies suggest that endostatin may locally modulate coronary collateral formation by inhibiting collateral vessel formation in patients with ischemic heart disease. During treadmill exercise tests in healthy volunteers a significant increase in circulating endostatin levels can be observed. Exercise induces angiogenesis in cardiac and skeletal muscles by decreasing endostatin in the muscle tissues to increase blood flow to these metabolically active tissues. Thereby endostatin is released into the general circulation. In summary, endostatin might be a new weapon to fight against atherosclerotic progression by inhibiting neo-vascularization of atherosclerotic plaques.
Hyperglycemia is common in critically ill patients and associated with an adverse outcome. Thus, glycaemic control is an important issue in critical care. Despite extensive efforts of the intensive care unit staff difficulties were experienced in achieving efficient and safe glucose control. A fully automated algorithm may help to overcome some of these limitations by excluding intuitive interventions and integrating relevant clinical data in the decision-making process. Space GlucoseControl (TGC system) is a decision support system which helps to achieve safe and reliable blood glucose control in the desired ranges. Information on parenteral and enteral nutrition is automatically integrated into the calculations. The primary objective of the current study is to investigate the performance and usability of the Space TGC system for glucose control in medical ICU patients.
This is a multicenter open-label uncontrolled phase II study. There are no previous clinical data to estimate the expected response rate of everolimus in MALT lymphomas and in the other less common MZLs (i.e. nodal and splenic) refractory or relapsing after at least 1 prior systemic treatment (chemotherapy or immunotherapy). The primary objective of this study is to define the antitumor activity, in term of overall response rate (ORR), as sum of complete remissions (CR) and partial remissions (PR) of everolimus in relapsed or refractory marginal zone B-cell lymphomas. The secondary objectives of this study are to assess safety, as acute or long-term toxicity, response duration (RD) (time to relapse or progression) in responders and progression-free survival (PFS) (time to disease progression or death from any cause) in all patients.
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether temozolomide is more effective when given with or without bevacizumab in treating patients with recurrent glioma. PURPOSE: This randomized clinical trial is studying how well temozolomide works with or without bevacizumab in treating patients with recurrent glioma.
Age-related macular degeneration (AMD) is by far the most common disorder in the group of irreversible causes of visual disability. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process and severely compromises the highly developed functions of the macula, such as perception of details, central fixation, color vision, and reading ability. AMD-related visual impairment is associated with a loss of autonomy and quality of life. Current therapeutic approaches target vascular endothelial growth factor (VEGF), which has been identified as a main cytokine in the pathogenesis of nAMD. Ranibizumab, the fab-fragment of an antibody targeting VEGF is approved for the treatment of nAMD applied intravitreally in monthly intervals until the disease activity is stopped. However, a significant proportion of patients with nAMD suffer from persistent or recurring disease with the need of continuous anti-VEGF therapy over months and years, often leading to irreversible changes in the photoreceptor layer and the pigment epithelium. Recent studies regarding the treatment of nAMD utilized different forms of therapies, combining photodynamic therapy with verteporfin (PDT) and ranibizumab, as well as therapeutic regimen containing steroids. Even though these studies did not provide evidence that combination therapies are superior to ranibizumab monotherapy, studies were only conducted with patients with previously untreated nAMD. Therefore, currently there is no alternative therapeutic approach for patients with recurrent or persistent form of nAMD after multiple treatments with ranibizumab monotherapy. The purpose of this study is to assess the treatment effect of reduced fluence PDT and intravitreal ranibizumab versus intravitreal dexamethasone and ranibizumab versus intravitreal ranibizumab monotherapy in patients with persistent or recurrent choroidal neovascularization (CNV) due to AMD. The investigators hypothesis is that these findings will offer new insights in the management of persistent or recurrent CNV secondary to AMD.
The purpose of this experimental pilot study is to assess a positive effect of higher injection volumes of fluid (physiological sodium) in the elbow-flection-muscle (M. biceps brachii) and elbow flexion and extension movements on fluid distribution in the muscle tissue.
The purpose of the study is to assess the efficacy and safety of Prothromplex Total as a treatment for the immediate reversal of oral anticoagulant therapy with vitamin K antagonists in patients with acquired deficiency of prothrombin complex coagulation factors (II, VII, IX, X). Upon enrolment, subjects will receive Prothromplex Total for the treatment of acute bleeding due to oral anticoagulants or for the prevention of excessive bleeding during the interventional procedure (Day 1). Additional doses of Prothromplex Total may be administered at the discretion of the investigator. Efficacy and safety assessments will be performed during a period of 72 (± 4) hours after administration of the last dose of Prothromplex Total or until discharge from hospital, whichever occurs first.
