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.
Rationale: The narrow therapeutic range and wide inter-patient variability in dose requirement make anticoagulation response to coumarin derivatives unpredictable. As a result, patients require frequent monitoring to avert adverse effects and maintain therapeutic efficacy. Polymorphisms in cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase complex 1 (VKORC1) jointly account for about 40% of the inter-individual variability in dose requirements. To date, several pharmacogenetic guided dosing algorithms for coumarin derivatives, predominately for warfarin, have been developed. However, the potential benefit of these dosing algorithms in terms of their safety and clinical utility has not been adequately investigated in randomised settings. Objective: To determine whether a dosing algorithm containing genetic information increases the time within therapeutic INR range during anticoagulation therapy with each of warfarin, acenocoumarol and phenprocoumon compared to a dosing regimen that does not contain this information. Secondary outcomes of the study include cost effectiveness, number of thromboembolic and bleeding events, time to reach stable dose and number of supratherapeutic INR peaks. Study design: This is a two-armed, single-blinded, randomised controlled trial. In one arm (intervention) patients commencing anticoagulation therapy with either warfarin, acenocoumarol or phenprocoumon will be dosed according to a drug-specific genotype-guided dosing algorithm, which is based on genetic information, clinical data and (in the monitoring phase) previous INR. For the other arm (control) patients will be dosed according to a non-genotype-guided dosing regimen which does not include genetic information. The follow-up period per patient is 3 months. Study population: Newly diagnosed patients of both genders and at least 18 years old who need anticoagulant treatment with either acenocoumarol, phenprocoumon or warfarin within the low intensity INR range will be included in the trial. Main study parameters/endpoints: The % time within therapeutic INR range in the first 3 months of anticoagulation therapy. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Six extra blood samples are taken from each participant at the start of the study. Patients also have to attend 8 scheduled visits within the 3 months study period and are asked to fill in questionnaires. The genotype-guided dosing algorithm is anticipated to improve the accuracy of coumarin dosing and thus improve the safety and efficacy of anticoagulation therapy.
The purpose of this study is to test the safety and efficacy of duloxetine versus placebo in elderly patients suffering from generalized anxiety disorder (GAD).
The purpose of the study is to evaluate the ability of Rituximab maintenance therapy to prolong progression free survival in patients with chronic lymphocytic leukemia, who responded to a Rituximab induction therapy.
This is a multiple vaccination study to find out if it is a safe treatment and what effects it has on the symptoms of early Alzheimer's disease in male and female patients aged 50 to 80 years. Approximately 40 study sites in Europe will be involved. Patients will be randomized to receive either AFFITOPE AD02 or placebo. Each patient's participation will last 1 year.
Conventional pain efficacy measures such as Visual Analogue Scores (VAS) are often unable to detect treatment efficacy in small-scale clinical trials. Combining conventional pain efficacy measures with quantitative sensory testing (QST) may provide more sensitive and informative outcome measures in clinical trials.
Rationale/Purpose: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating young patients with acute lymphoblastic leukemia (ALL). This trial is studying several different combination chemotherapy regimens to compare how well they work in treating young patients with ALL. Study objectives Primary study questions: - Non high-risk (non-HR) precursor-B ALL (pB-ALL) patients with TEL/AML1-negative ALL or unknown TEL/AML1 status and flow cytometry minimal residual disease (MRD) in bone marrow on day 15 <0.1% or with TEL/AML1-positive ALL (randomized study question R1): Can the daunorubicin dose in Protocol IA be safely reduced by 50 % with a non-inferior EFS and a reduction of toxicity (treatment-related mortality and AE/SAE in Protocol I)? - Patients with pB-ALL and risk group medium risk (MR) (randomized study question R2): Can the clinical outcome be improved by protracted asparagine depletion achieved through application of intensified PEG-L-asparaginase during reintensification and early maintenance? - High-risk (HR) patients (as identified by day 33 - randomized study question RHR): Can the clinical outcome be improved by protracted exposure to PEG-L-asparaginase during Protocol IB? Secondary study questions: - Standard risk (SR) patients identified by at least one sensitive marker: Is the clinical outcome comparable to that obtained in SR patients (identified with two sensitive markers) in AIEOP-BFM ALL 2000, or can the outcome even be improved with the use of PEG-L-asparaginase instead of native E. coli L-ASP? - T-ALL non-HR patients: Can the high level of outcome which was obtained for these patients in study AIEOP-BFM ALL 2000 be preserved or even improved with the use of PEG-L-ASP instead of native E. coli L-ASP? - HR patients with persisting high MRD levels despite the use of the HR blocks in the intensified consolidation phase "MRD Non-Responders": Is it possible to improve the outcome and to achieve a further reduction of leukemic cell burden by administration of an innovative treatment schedule (DNX-FLA)? - Patients participating in the randomized asparaginase studies (pB-ALL/MR, HR): Are asparaginase activity and asparaginase antibodies associated with development of allergic reactions, and do they have an effect on the outcome of the patients? - What is the relative value of different methods of MRD monitoring in the definition of alternative stratification systems within a BFM-oriented protocol?
Primary objective: To demonstrate the superiority of insulin glargine over liraglutide in terms of percentage of patients reaching a Glycosylated Haemoglobin (HbA1c) < 7% at the end of the comparative period (24 weeks) in Type 2 diabetic patients failing lifestyle management and oral agents Secondary objectives of the comparative period (24 weeks): >To assess the effect of insulin glargine in comparison with liraglutide on: - HbA1c level - Percentage of patients whose HbA1c has decreased but remains >= 7% at the end of the comparative period - Percentage of patients whose HbA1c has increased at the end of the comparative period - Fasting Plasma Glucose (FPG) - 7-point Plasma Glucose (PG) profiles - Hypoglycemia occurrence - Body weight - Adverse events Objectives of the extension period (24 weeks): >To assess the effect of insulin glargine in patients not adequately controlled with liraglutide on: - HbA1c level - FPG - 7-point PG profiles - Hypoglycemia occurrence - Body weight - Adverse events

The Enable Aortic Valve is an equine pericardial stented bioprosthesis.
The purpose of this study is to determine whether an early Calcineurin Inhibitor (CNI) to everolimus conversion at 10-14 weeks post transplantation improves renal allograft function without compromising efficacy compared to standard CNI treatment in de novo renal allograft recipients. In addition, the study is designed to evaluate the impact of a CNI-free regimen on evolution of cardiovascular parameters in de novo renal allograft recipients
