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.
Atrial fibrillation (AF) is the most common heart rhythm disorder, impairs quality of life and increases stroke risk and mortality. Despite advances in medical treatment, AF remains uncontrolled in many patients. In many patients, AF is initiated by abnormal electrical impulses from the pulmonary veins. A catheter ablation procedure called pulmonary vein isolation (PVI) has therefore been developed, using heat to isolate the PV foci from the heart. PVI is very effective, but must be repeated in up to 50% of cases because the foci isolation is not permanent after initial PVI. The intravenous administration of a drug called adenosine during the PVI procedure can unmask residual conduction that would otherwise remain unnoticed, so-called "dormant conduction". In our experience, additional ablation guided by adenosine reduces AF recurrence and the need for a repeat PVI procedure. However, the adenosine-guided approach has not yet been proven as standard therapy. The present study, to be conducted at 15 clinical centres in Canada, Europe and Australia is therefore intended to evaluate the efficacy of adenosine-guided ablation to prevent AF recurrence. Five hundred twenty-six patients will be included in the study, which should be completed within 2 years. In all patients, the presence of dormant conduction will be tested with adenosine during PVI. If dormant conduction is observed, additional ablation will be performed in half of these patients selected randomly. If there is no dormant conduction, randomly selected patients will be followed in a registry. If the adenosine-guided approach is demonstrated to improve the success rate of PVI procedures, it should become the standard approach for a "permanent cure" of AF, and therefore benefit patients by reducing arrhythmia recurrence, hospitalizations and the need for repeat interventions.
Prevention of invasive fungal infection in high risk patients following liver transplant.
The investigators aim to analyse in adolescents with mental illness effectiveness, side effects, and serum level concentrations of antipsychotics (olanzapine and aripiprazole), antidepressants (Duloxetine, Atomoxetine) by means of "Therapeutic Drug Monitoring" (TDM) in order to optimize dosage - effect relations and minimize unwanted side effects.
Single Incision Laparoscopic Surgery (SILS) can be performed for different standard operations such as appendectomy and cholecystectomy. During laparoscopic cholecystectomy sometimes a cholangiography (marking the biliary tract with contrast agent) is necessary to identify and preserve relevant structures. The investigators want to evaluate feasibility of performing cholangiography during SILS cholecystectomy.
To evaluate the clinical performance of the PRO-Kinetic ENERGY® coronary bare metal stent system in a patient population within that defined in the Instructions for Use.
The purpose of this study is to assess the safety and usability of the Solo™ insulin MicroPump in subjects with type 1 diabetes who are pump users.
The aim of this study is to describe Health Related Quality of Life (HRQoL) in adolescents and adults with Hemophilia A treated prophylactically or on-demand with Helixate NexGen. The study will also assess the kinds of determinants, including key transitional life events, that might impact HRQoL in this patient population.
The purpose of the study is to compare non-obese patients (BMI≤ 30 kg/m2)versus obese patients (BMI> 30 kg/m2) in regard of their respective needs for intraoperative fluid therapy during laparoscopic surgery. Specifically the investigators will test the hypothesis that subcutaneous tissue oxygenation (PsqO2)is increased in obese patients when fluid management is optimized by means of esophageal Doppler monitoring compared to obese patients undergoing standard fluid management. Furthermore the investigators will test the hypothesis that PsqO2 is decreased in obese patients undergoing conventional fluid therapy compared to non-obese patients when fluid management is optimized. Thus the investigators assume that PsqO2 is similar in obese and non-obese patients when fluid management is optimized in both groups.
The purpose of this study is to evaluate the safety and efficacy of AeriSeal treatment in patients with advanced emphysema.
This trial is conducted in Asia, Europe and the United States of America (USA). The aim of this trial is to compare the efficacy and safety of NN5401 (insulin degludec/insulin aspart (IDegAsp)) with insulin glargine (IGlar), both as add-on to subject's ongoing treatment with metformin + at least one OAD (oral anti-diabetic drug). The main period is registered internally at Novo Nordisk as NN5401-3590 while the extension period is registered as NN5401-3726.
