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.
Age-related macular degeneration (AMD) is the chief cause of severe and irreversible loss of vision in developed countries. The prevalence of AMD increases dramatically with age. The early stage (or dry AMD) is associated with minimal visual impairment and is characterized by large drusen and pigmentary abnormalities in the macula. The late stage is a neovascular, exudative form. This so called exudative AMD includes serous or hemorrhagic detachment of retinal pigment epithelium and choroidal neovascularization leading to severe loss of vision (20/200 or worse). Patients with unilateral CNV (choroidal neovascularisation) have a significant risk of CNV developing in the second eye. Choroidal blood flow is of great importance for normal visual function. Several reports have provided evidence suggesting that choroidal blood flow is decreased in subjects with AMD. In late stages of AMD angiogenesis leads to the formation of choroidal neovascularization that can cause severe visual impairment by disrupting normal macular function. The purpose of this evaluation is to investigate a possible link between alterations in choroidal blood flow and the development of CNV and serous detachment in the fellow eye of patients with AMD and unilateral neovascular maculopathy. This longitudinal study may provide important findings with respect to natural history and visual prognosis of patients with neovascularized AMD. Ocular blood flow will be determined by non-invasive methods, including laser Doppler flowmetry and laser interferometry
The purposes of this study are: 1. To evaluate the long-term safety of dabigatran etexilate 2. To assess the effect of a knowledge translation intervention on patient outcomes
In patients with high gastric residual volumes jejunal feeding is recommended. Jejunal feeding tubes can be placed in different ways. The endoscopic technique yields a success rate between 90 and 98% for a correct jejunal placement. However, it requires endoscopic equipment and trained staff. In contrast in small uncontrolled trials different unguided techniques resulted in success rates up to 75%, only. In this prospective randomized trial the success rate of a correct jejunal placement with the endoscopic technique is compared with the unguided frictional technique. The investigators hypothesize that the success rate of the unguided frictional placement method will be lower than the success rate of the endoscopic method.
To compare the efficacy of escitalopram fixed dose 20 mg/day in combination with fixed doses of gaboxadol (5 and 10 mg/day) versus escitalopram fixed dose 20 mg/day after 8 weeks of treatment in patients with Major Depressive Disorder
Autoregulation is defined as the ability of a vascular bed to adapt its vascular resistance to changes in perfusion pressure. In the eye, several studies have reported that retinal blood flow is autoregulated over a wide range of ocular perfusion pressures. The investigators recently showed that nitric oxide (NO) is a key metabolite in the regulation of vascular tone in the eye and plays an important role in the blood flow autoregulation of the choroidal circulation. However, no data is yet available for the optic nerve head. Thus, the present study is designed to test the hypothesis that NO plays also a role in optic nerve head blood flow autoregulation. Therefore, subjects will perform squatting to increase systemic perfusion pressure during administration of either a nitric oxide synthase inhibitor (L-NMMA), an α-receptor agonist (phenylephrine) or placebo. Optic nerve head blood flow will be continuously measured during the procedure to investigate optic nerve head autoregulation.
This observational (non-interventional) post-authorization safety study (PASS) will investigate the application of Venofundin 6% and of Tetraspan 6% in children with special regard to drug safety.
This purpose of this study is to investigate the efficacy and tolerability of pregabalin in treating idiopathic RLS patients for up to 12 months.
Primary objective: - To assess the efficacy of eplivanserin 5mg/day in comparison to placebo after 6 weeks of treatment on sleep maintenance of insomniac patients, as measured by Polysomnography Wake Time After Sleep Onset (PSG-WASO) and Polysomnography Number of Awakenings (PSG-NAW). Secondary objectives: - To evaluate the effects of eplivanserin 5mg/day as compared to placebo after 6 weeks of treatment on other sleep parameters measured by PSG recordings (Total Sleep Time - PSG-TST, Sleep Efficiency - PSG-SE, Latency to Persistent Sleep - PSG-LPS) and reported by patients (Wake Time After Sleep Onset - pr-WASO, Number of Awakenings - pr-NAW, Total Sleep Time - pr-TST, Quality of Sleep - QoS and Refreshing Quality of Sleep - RqoS). - To evaluate the effects of eplivanserin 5mg/day on sleep architecture compared to placebo. - To evaluate the effect of eplivanserin 5mg/day on daytime functioning using the Sleep Impact Scale (SIS), as compared with placebo after 6 weeks of treatment. - To evaluate patient's impression of treatment effects using the Patient's Global Impression questionnaire. - To evaluate the potential for next-day residual effects (using patient's morning questionnaire and psychometric tests) with eplivanserin 5mg/day as compared to placebo. - To evaluate the potential for rebound insomnia following abrupt discontinuation of eplivanserin 5mg/day in comparison with placebo. - To evaluate the effect of eplivanserin, compared to placebo, on the quality of life of patients with primary insomnia using the SF-36 Health Survey. - To evaluate the clinical safety and tolerability of eplivanserin 5mg/day compared to placebo.
The present trial will be performed to evaluate whether BIBF 1120 in combination with standard therapy of docetaxel in patients with stage IIIB/IV or recurrent NSCLC is more effective as compared to placebo in combination with standard therapy of docetaxel. A secondary aim is to obtain safety information as well as information on quality of life of patients treated with BIBF 1120 in combination to standard therapy with docetaxel. In addition, blood will be collected for pharmacokinetic analysis.
A multicenter, multinational, randomized,double-blind, placebo-controlled study in patients with Type 2 Diabetes Mellitus (T2DM). Patients with inadequate glycemic control using diet and exercise alone, or in combination with metformin, will be enrolled. The primary objective of this study is to test the hypothesis that LY2428757 given to patients with T2DM inadequately controlled with diet and exercise alone, or metformin monotherapy, produces a significant decrease in the mean hemoglobin A1c (HbA1c) from baseline to endpoint at 12 weeks as compared to placebo. Trial consists of 12 weeks of double-blind treatment and 4-week safety follow-up.
