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.
The purpose of this study is to test the safety and effectiveness of the Medtronic CapSureFix Novus Model 5076 lead when patients are implanted with the Medtronic Advisa MRI pacemaker and undergo an MRI scan.
In the elderly population, dry eye syndrome is a highly prevalent ocular disease. One mainstay of therapy for patients suffering from dry eye syndrome is the use of topically administered lubricants. One of the main disadvantages of the formulations currently available for the treatment of DES is the short residency time on the ocular surface, which increases the need for a frequent instillation of the lubricant. Recently, Croma Pharma has introduced chitosan-N-acetylcysteine eye drops, designed for treatment of symptoms related to DES. Based on theoretical considerations and animal experiments, the new chitosan derivative may show an increased adhesion to mucins of the ocular surface and may therefore considerably increase the residence on the ocular surface. This, in turn, would limit the need for frequent treatment and decrease the burden for the patients. It has been shown in recent Phase I studies that chitosan-N-acetylcysteine eye drops are safe and well tolerated after single and repeated instillation. The current study seeks to investigate the ocular residency time after a single dose and after 5 day b.i.d. treatment. For this purpose 2 cohorts are planned: In Cohort I, chitosan-N-acetylcysteine eye drops will be instilled once in one randomly chosen eye, whereas the fellow eye will receive placebo. Measurements of tear film thickness will be performed with optical coherence tomography (OCT) before instillation and 10 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 10 hours, 12 hours and 24 hours after instillation. In addition, ocular scattering of the tear film will be assessed with an Optical Quality Analysis System (OQAS) at the same timepoints. Determination of break up time (BUT) will be performed before and after instillation of the eye drops. In Cohort II, chitosan-N-acetylcysteine eye drops will be instilled once daily in one eye and b.i.d. in the fellow eye on five consecutive days. Measurements of tear film thickness with OCT and OQAS will be performed every study day before the morning instillation and the day after the last instillation. Additionally, patients will be asked to answer the ocular surface disease index (OSDI©) on day 1 and day 6. BUT will be determined before and after instillation of the eye drops.
Dry eye syndrome (DES) is a highly prevalent ocular condition inducing an inflammatory response of the ocular surface. Common symptoms include ocular discomfort, visual impairment and instability of the tear film with potential damage to the ocular surface. The rationale of the present study is to compare signs as assessed with new methods such as measurement of tear film thickness, tear film osmolarity and scattering of the tear film with well established methods for assessment of the severity of DES (Break up time, staining of the cornea with fluorescein). Additionally, impression cytology and determination of tear cytokines/chemokines will be performed to obtain information about inflammatory processes on the ocular surface.
Corneal lesions such as corneal abrasions and corneal infiltrates are common in clinical practice. The current study seeks to investigate whether high-resolution OCT is suitable for imaging of these corneal lesions. The present study has the character of a pilot study and the results are intended to be used to develop a standardized protocol for imaging and analysis of these corneal lesions. Based on this protocol, further studies investigating the pathophysiology of corneal lesions or evaluating therapeutic success can be planned.
The purpose of the study is to document long-term response in real-life practice after injection cycles with BoNT-A in subjects suffering from idiopathic cervical dystonia (Long-term clinical and pharmaco-economic data).
The purpose of this trial is to investigate the efficacy and safety of lidocaine 5% medicated plaster in localized chronic post-operative neuropathic pain in comparison to placebo plaster.
Necrotizing enterocolitis (NEC) is one of the most devastating gastrointestinal emergencies in preterm neonates and a leading cause of death and morbidity. The pathogenesis of NEC remains largely unclear, but it is widely considered as a multifactorial disease. Prematurity, enteral feeding, bacterial colonisation of the gut and intestinal ischemia have been proposed as major risk factors. Probiotics may prevent NEC by improving the maturity and function of the gut mucosal barrier, modulating the immune system, promoting colonization of the gut with beneficial organisms and preventing colonization by pathogens. A variety of clinical trials have evaluated the effect of different probiotic preparations on the occurrence of NEC in preterm infants. The results of recent metaanalyses suggest a benefit of probiotic bacteria in reducing the incidence of NEC and propose a change of practice. The aim of the study is to evaluate the efficacy of the probiotic preparation Infloran® in reducing the incidence of NEC after implementation in clinical routine in preterm (< 34 weeks gestational age) very low birth weight infants compared to a historical cohort.
The purpose of the study is to evaluate the safety and efficacy of the Medtronic Attain Performa Quadripolar Leads (Model 4298, 4398, and 4598) during and post the implant procedure. This study will also assess the interactions of the Attain Performa leads with the entire Medtronic CRT-D system.
Low total testosterone (TT) is present in about 30% of men aged >60 years and in up to 7% of younger men. Male hypogonadism is associated with metabolic and cardiovascular diseases as well as with increased mortality. There is evidence showing a relationship of TT with vitamin D in men. We aim at evaluating the effect of vitamin D supplementation on TT and metabolic parameters in hypogonadal men. We will study the effects of 20,000 IU vitamin D weekly in a 12 wk randomized, double-blind, placebo-controlled trial in 100 men with TT <3.0 ng/ml and 25-hydroxyvitamin D (25(OH)D) <30 ng/ml (patients) as well as in 100 men with TT ≥3.0 ng/ml and 25(OH)D <30 ng/ml (controls). Vitamin D supplementation might be a safe therapeutic approach improving TT levels as well as metabolic parameters in hypogonadal men. Further the effects of vitamin D on androgens will be evaluated in eugonadal men.
The purpose of this study is to investigate if ONO-4053 relieves symptoms of allergic rhinitis in seasonal allergic rhinitis subjects exposed to pollen under controlled conditions.
