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 prevalence of diabetes and diabetes-associated complications is still increasing. Several major long-term complications of diabetes such as cardiovascular disease, chronic renal failure, diabetic retinopathy and others relate to the damage of blood vessels. Given that the eye provides the unique possibility in the human body to directly visualize blood vessels, much interest has been directed towards studying the ocular circulation. Although data of large epidemiological studies indicate that changes in retinal vessel caliber reflect other diabetes related factors, such as fasting glucose levels, there is still conflicting evidence on blood flow alterations in patients with diabetes. This is also related to the fact that up to now, methodological difficulties aggravate the assessment of blood flow changes in the retina in larger groups of patients. In the present study we propose to overcome this problem by using a technique called bi-directional Fourier Domain Doppler Optical Coherence Tomography (FDOCT), which we have developed in the recent years to measure retinal blood velocities. This technique allows for the non-invasive investigation of blood flow changes in human retina and will help us to better understand diabetes related vascular changes. The present study will use this technique to assess retinal blood flow changes in patients with diabetes and healthy subjects.
The aim of the present study is to develop a protocol for optimal corneal 3-dimensional imaging based on measurements in healthy volunteers. For this purpose, a customized ultra-high resolution Spectral Domain OCT will be used. To validate whether the protocol can also be applied in patients with corneal pathologies, for whom it is intended to be used, measurements in these patients will be performed. We propose to obtain images from patients with keratoconus, since this is one of the most frequent causes for corneal transplantations in Europe and from patients with corneal neovascularization which is a major cause of vision loss in several ophthalmic diseases. Based on the obtained measurement protocol, further studies investigating the pathophysiology or treatment success of several corneal pathologies can be planned.
Botulinum toxin A (BoNT-A) is effective and safe in alleviating post-stroke spasticity and reducing the burden of associated symptoms. The hypothesis for this non-interventional study in arm spasticity (AS-NIS early BIRD) is no significant difference between naïve and pre-treated patients. The patients will be divided in sub-groups according to the time interval between occurrence of stroke and start of treatment (early, medium and late start of treatment according to the first and third quartiles time distribution). It is hypothesized that the "early" start of treatment group will have a reduced modified Ashworth scale (MAS) on the elbow and wrist flexors when compared to the "late" start of treatment group.
The objective of this study is to investigate the efficacy of Dysport® in the treatment of cervical dystonia (CD) in a non-interventional long-term study in naïve and pre-treated patients.
The aim of the study is to identify predictive factors for the response to Lanreotide treatment in Acromegaly as well as in Neuroendocrine Tumours.
The hypothesis of this study is to find evidence if there is an influence of spine surgery on the serum levels of two proteins secreted from neuronal cells.
This was a clinical effectiveness trial designed to compare the effectiveness, safety, and tolerability of treatment with tapentadol prolonged release with that of oxycodone/naloxone prolonged release in non-opioid pre-treated subjects with severe chronic low back pain with a neuropathic pain component. Both tapentadol and the opioid oxycodone are effective in chronic severe pain and tapentadol and oxycodone/naloxone have shown advantages in gastrointestinal tolerability versus oxycodone. Therefore, it was of high scientific interest to compare the latter 2 analgesics with respect to gastrointestinal tolerability. Tapentadol may have advantages regarding the neuropathic pain-related symptoms of low back pain due to its 2 mechanisms of action.
Evaluation of the best therapeutic index for patients with platinum-sensitive ovarian cancer when treatment with bevacizumab and gemcitabine/carboplatin or with bevacizumab and PLD/carboplatin.
Purpose: This study investigates the effects of dietary zeolite + dolomite on performance, exercise-induced acidosis, oxidative stress, inflammation and intestinal barrier dysfunction in trained people. Hypotheses (H1): Zeolite + dolomite increase performance in an ergometer step test Zeolite + dolomite reduce exercise-induced acidosis Zeolite + dolomite reduce oxidative stress Zeolite + dolomite reduce inflammation Zeolite + dolomite improve intestinal barrier dysfunction
This is a Non-interventional Prospective Study. Centres will enroll adult patients with partial onset seizures for whom the clinician has decided to initiate ZNS as an adjunctive therapy prior to the decision to take part in this study. Patients to be enrolled into the study are not sufficiently controlled with one dug licensed for the use of monotherapy in partial onset seizures. Patients will be seen at baseline and then during normal clinical visits at intervals which are appropriate to the typical practice of the treating clinician. Patients will be assessed at baseline and then at least 3 and 6 months after the baseline.
