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.
Background: The assessment of extent of disease (staging) and response to therapy (restaging) is performed with computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET scan) or integrated FDG-PET/CT. Whole-body MRI with diffusion weighted imaging (WB-MRI with DWIBS) is a radiation-free method which allows imaging of the body with excellent soft tissue contrast in a single examination and could be an attractive alternative to FDG-PET and CT for the staging and restaging of malignant lymphomas in children. Aim of the study: The aims of this study are to compare the diagnostic performance of whole-body MRI (including DWIBS) to FDG-PET/CT and/or CT for the initial staging, early response assessment and restaging after completion of therapy in children with Hodgkin's lymphoma. Study design: Patients eligible for enrollment in this multicenter, prospective, diagnostic cohort study are children aged 8-18 years, with histologically confirmed Hodgkin's lymphoma, who are treated according to the EuroNet-PHL-C1 protocol (or trial with similar imaging strategy) in one of the participating centers. Patients will undergo WB-MRI in addition to the protocolar imaging routinely done (FDG-PET(/CT) and CT scan) at 3 time-points: at initial staging, after 2 chemotherapy cycles and at end of treatment. The investigators expect to enrol 75 patients in a 3 year study period. Staging and restaging results of WB-MRI (according to the Ann Arbor and Cheson classification, respectively) will be compared to those of FDG-PET(/CT) and CT. Clinical and radiological follow-up after 6 months will be used to solve any disagreements between FDG-PET, CT and WB-MRI. Additionally, the investigators will collect 3 year follow-up clinical data and data on follow-up imaging from the hospital charts of the patients, to better assess the prognostic value of FDG-PET and WB-MRI.
This was a 64-week randomized, double-masked, multi-center, active-controlled, two-arm study in patients with neovascular age related macular degeneration (nAMD) who have not previously received anti- vascular endothelial growth factor (VEGF) treatment.
The purpose of this study is to demonstrate how well aflibercept works in babies with ROP, comparing it with laser therapy. The study also has the objective to demonstrate how safe aflibercept is when used in babies, and describe how the drug moves into, through and out of the body.
Preclinical emergency management is frequently associated with a combination of physical and psychological stress. This stress is known to lead to a broad variety of changes in the physiology even extending in the cardiovascular system. Both physical and psychological stress induces ECG changes. These changes include not only arrhythmias but also deviations in ST-T segment representing the phase of repolarization. Information about changes in ST-T segment are missing until now. The investigators hypothesise that ST-T deviations occur in emergency physicians during shift at an emergency response car. In order to show changes in ST-T segment a prospective observational trial will be conducted. By using a 12 lead ECG Holter the investigators will obtain ECGs during shifts of emergency physicians at an emergency response vehicle. During 12-hour shifts emergency physicians will be attached to the 12 lead Holter ECG. ECGs will be analysed after blinding of names and reason of call (code) to the investigators. The primary outcome will be ST-T segment changes greater than 0.1mV in two corresponding leads for more than 30 seconds per 100 calls. As secondary outcomes, other ECG changes such as ST-T segment changes <0.1mV, T wave inversion or HRV will be analysed. Furthermore, surrogate parameter of stress will be measured using NASA-Task Load Index and cognitive appraisal and correlated to ST-T segment changes. Correlations between different phases of calls, different indications of calls and ECG changes will be assessed. Furthermore, correlation between alarm codes apriori defined as stressfull using a delphi process and ST-T segment changes as well es surrogate parameters of stress will be assessed.
There is evidence that a folate deficiency - and as the biological consequence of the latter - higher homocysteine plasma levels are associated with an increased risk of vascular associated diseases. For the eye, it has been shown that higher intake of folate reduces the risk of vascular related diseases such as age related macular degeneration. Further studies suggest that decreased serum levels of folate and vitamin B12 may be an independent risk factor for diabetic retinopathy. The reason for the association of low folate levels and the increased risk for vascular-associated ocular diseases is not entirely clear but may be at least partially related to an impairment of local blood flow regulation in these patients. Whether supplementation with folate may improve vascular regulation has not yet been sufficiently investigated. However, given that the potential effect size of a folate substitution on blood flow and systemic blood parameters is unclear, a proper statistical design for a large, controlled, randomized study is difficult. Thus, the present pilot study should (1) provide information about the homocysteine lowering potential of the formulation under study and (2) identify potential vascular related outcome parameters for further, larger, placebo-controlled studies and provide sufficient data to allow for a proper statistical planning for such a study. Consequently, the current study seeks to investigate the effect of a 3-month supplementation with folate on systemic homocysteine plasma levels. Further, ocular blood flow and endothelial function in the ocular microcirculation will be assessed. For this purpose, a group of 25 patients with diabetes mellitus will be included in the study. Outcome parameters will be assessed at baseline and after a 3-month supplementation with folate.
The purpose of this study is to assess the efficacy of etrasimod on clinical remission in participants with moderately to severely active ulcerative colitis (UC).
The primary objective of this study is to demonstrate the efficacy and safety of linzagolix administered orally once daily for 3 months at a dose of 75 mg alone or of 200 mg in combination with add-back hormone replacement therapy (ABT: estradiol (E2) 1 mg / norethisterone acetate (NETA) 0.5 mg) versus placebo, in the management of moderate to severe endometriosis-associated pain (EAP).
The main purpose of the study is to assess the efficacy and safety of nemolizumab after a 16-week treatment period in adult and adolescent subjects with moderate-to-severe atopic dermatitis (AD) not adequately controlled with topical treatments.
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), and antidrug antibody (ADA) response for MEDI8897 in healthy late preterm and term infants who are 35 weeks or greater gestational age and entering their first RSV season.
This study evaluates the efficacy of home-based high tone external muscle stimulation (HTEMS) compared to transcutaneous electrical nerve stimulation (TENS) in chemotherapy-induced peripheral neuropathy (CIPN). One half of the participants will receive TENS therapy, the other half will receive High tone external muscle Stimulation. It is expected that HTEMS improves symptoms of CIPN.
