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.
This is a prospective study to extensively evaluate subjective patient parameters on quality of life, reflux-symptoms, side effects, medication-use and measurements of esophageal manometry and Impedance-pH-Monitoring after Full-Thickness-Gastroplication.
Efficacy and safety of a supportive treatment with European mistletoe extract Iscador® Qu ("quercus", i.e. from oak tree) in patients with colorectal cancer (Union for International Cancer Control, UICC stages II-IV), in addition to post-operative conventional oncological therapy (radio-, chemo-, targeted therapy) as compared to a parallel group with conventional therapy only. Primary Endpoints: Reduction of adverse effects of conventional therapy; reduction of therapy or disease induced symptoms (both are quality of life parameters and evaluated after 1 year); prolongation of disease free and/or overall survival (DFS, OS) after 5 years. Prospective observational confirmation study of previous retrospective cohort study. As this is a non-interventional cohort study, all therapies and measurements are performed on directive by the treating physician and/or request by the patient only.
Clefts or invaginations of the gingival tissue are a frequent finding during orthodontic space closure after extraction of a tooth. They occur in about 35% of the cases. Increased risk of developing a gingival cleft is given in the mandibular arch. A gingival invagination impairs aesthetics, orthodontic treatment and periodontal health. The aim of this prospective split-mouth designed observer blinded study is to evaluate possible differences between tooth movement in recent or in healed extraction sockets on incidence of gingival clefts. We hypothesize, that similar to the results originated from an animal study immediate movement in extraction sockets reduces incidence of gingival clefts during orthodontic space closure.
The purpose of the Endostroke Registry is to gather information on predictors of good or poor clinical outcome following mechanical recanalization therapies for acute ischemic stroke.
The purpose of this study is to investigated and evaluated the effectiveness of a new surgical technique for the treatment of severe chronic pain stages (Complex Regional Pain Syndrome Type II).
In patients with liver cirrhosis elevated levels of von Willebrand factor antigen (vWF-Ag) are found frequently but the clinical significance is unclear. vWF-Ag plays an important role in primary haemostasis and development of thrombotic vascular obliteration is discussed as a possible mechanism leading to portal hypertension. Invasive measurement of hepatic venous pressure gradient (HVPG) is the current gold standard for the diagnosis of portal hypertension. The investigators hypothesize that vWF-Ag levels in plasma may correlate with portal pressure and predict clinically significant portal hypertension (CSPH, HVPG >=10mmHg) and its complications.
The purpose of this study is to examine the long-term safety of Abatacept for the treatment of juvenile idiopathic arthritis (JIA) with particular in interest in the occurrence of serious infections, autoimmune disorders, and malignancies.
Patients with relapsed medulloblastoma, ependymoma and ATRT have a very poor prognosis whether treated with conventional chemotherapy, high-dose chemotherapy with stem cell rescue, irradiation or combinations of these modalities. Antiangiogenetic therapy has emerged as new treatment option in solid malignancies. The frequent, metronomic schedule targets both proliferating tumor cells and endothelial cells, and minimizes toxicity. In this study the investigators will evaluate the use of biweekly intravenous bevacizumab in combination with five oral drugs (thalidomide, celecoxib, fenofibrate, and alternating cycles of daily low-dose oral etoposide and cyclophosphamide), augmented with alternating courses of intrathecal etoposide and cytarabine. The aim of the study is to extend therapy options for children with recurrent or progressive medulloblastoma, ependymoma and ATRT, for whom no known curative therapy exists, by prolonging survival while maintaining good quality of life. The primary objective of the MEMMAT trial is to evaluate the activity of this multidrug antiangiogenic approach in these heavily pretreated children and young adults. Additionally, progression-free survival (PFS), overall survival (OS), as well as feasibility and toxicity will be examined.
The pathomechanisms of COPD are still not fully understood, and up to now there is no satisfying causal treatment inhibiting the progress of the disease. Available therapy is in most cases symptomatic. Experimental and clinical observations suggest that treatment with ASA might be beneficial in the treatment of COPD in terms of respiratory and lung-functional improvement. To evaluate the efficacy of ASA as add-on therapy in COPD in comparison to placebo a prospective, randomized, double-blind, placebo controlled study will be conducted. Adult male and female patients (n=74) with proven COPD GOLD grade II-III will be randomized to 2 groups (i.e. 37 patients per group, stratification according to smoking status and gender). They will receive either 500 mg ASA per day or matching placebo over 12 weeks. Primary efficacy endpoints are changes in the lung-functional parameter FEV1 (forced expiratory 1-second volume) after 12 weeks of treatment. Secondary endpoints are the health score of the St. Georges respiratory questionnaire (SGRQ) and Peak-flow (PEF).
The negative effect of internal mammary harvesting on sternal perfusion is well known, especially in diabetic subjects. Microdialysis previously showed increased lactate tissue concentration after mammary artery preparation. Although high antibiotic concentration is of utmost importance in this region, no study previously measured the effect of internal mammary artery harvesting on target tissue antibiotic concentration. Study hypothesis: Internal mammary artery harvesting imposes an additional risk for deep sternal wound infection by impairing antibiotic tissue penetration. This effect is mediated by altered perfusion patterns and may be seen in cephalosporin and/or Teicoplanin treatment. Study objective: To evaluate the impact of left internal mammary artery preparation on target tissue antibiotic concentration of Cefazolin and Teicoplanin during cardiac surgery Design: This study is designed as an observational pharmacokinetic trial. Patients are their own controls by measuring antibiotic concentration in different subcutaneous tissues. Study population: Patients referred for coronary artery bypass grafting to the Department of Cardiothoracic Surgery with planned unilateral left internal mammary artery preparation and a high risk profile for deep sternal wound infections will be asked to participate in this trial.
