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.
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. Large scale studies have shown that reduced ocular perfusion pressure is an important risk factor for the prevalence, the incidence and the progression of primary open angle glaucoma. There is also evidence that autoregulation is impaired in patients with primary open angle glaucoma. To gain more insight into these phenomena in humans is the primary goal of the present study. The present study aims to investigate the pressure/flow relationship as a measure for retinal blood flow autoregulation during an experimental increase in intraocular pressure by the use of the suction cup technique. Retinal blood flow will be measured by Doppler OCT.
The objectives of Sub-Study 1 are to evaluate the efficacy, safety, and pharmacokinetics of risankizumab as induction treatment in subjects with moderately to severely active ulcerative colitis (UC), and to identify the appropriate induction dose of risankizumab for further evaluation in Sub-Study 2. The objective of Sub-Study 2 is to evaluate the efficacy and safety of risankizumab compared to placebo in inducing clinical remission in subjects with moderately to severely active UC.
A committee will judge the safety and effectiveness of edoxaban and the regular treatment (standard of care). All children in the study will receive free treatment. They will have a 2 in 3 chance to receive edoxaban, and a 1 in 3 chance to receive the standard of care for preventing blood clots. The study will find out if edoxaban is safer and more effective than the standard of care.
In this study the investigators aim to investigate the changes of the intestinal microbiome in three different cohorts (IBD, IBS, healthy) after applying the uniform disruptive factor of osmotic diarrhea induced by macrogol. The investigators hypothesis is that ill people will show more severe changes of the microbiome than healthy people and that these changes persist longer.
The objectives of this study are to evaluate the efficacy, safety, tolerability, pharmacokinetics, and pharmacodynamics of PF-06651600 (200 mg for 8 weeks followed by 50 mg for 4 weeks) dosed once daily and PF-06700841 (60 mg for 12 weeks) dosed once daily during an induction period of 12 weeks, followed by an open label extension period at doses of 50 mg and 30 mg of PF 06651600 and PF 06700841, respectively, for 52 weeks.
A randomized, double-blind study to assess the safety, tolerability, PK and efficacy of EDP-305 in subjects with primary biliary cholangitis
Thrombotic thrombocytopenic purpura (or TTP for short) is a condition where blood clots form in small blood vessels throughout the body. The clots can limit or block the flow of oxygen-rich blood to the body's organs, such as the brain, kidneys, and heart. As a result, serious health problems can develop. The increased clotting that occurs in TTP uses up the cells that help the blood to clot, called platelets. With fewer platelets available in the blood, bleeding problems can occur. People who have TTP may bleed underneath the skin forming purple bruises or purpura, or from the surface of the skin. TTP also can cause anemia, a condition in which red blood cells break apart faster than the body can replace them leading to lower than normal number of red blood cells. A lack of activity in the ADAMTS13 enzyme, a protein in the blood involved in blood clotting, causes TTP. The enzyme breaks up another blood protein called von Willebrand factor that clumps together with platelets to form blood clots. Some people are born with this condition, others get the condition during their life. Many people who born with TTP experience frequent flareups that need to be treated right away. If not treated It can be fatal or cause lasting damage, such as brain damage or a stroke. BAX 930 is a medicine that replaces ADAMTS13 and can prevent or control TTP flareups, called TTP events. The main aim of this study is to compare the number of TTP events in people born with severe TTP when they treated with BAX 930 versus when they are treated with the standard treatment. Treatment will be given in 2 ways: - BAX 930 or standard treatment given to prevent TTP events from happening. - BAX 930 or standard treatment given to control an acute TTP event when it happens, according to the clinic's standard practice. Both BAX 930 and standard treatment are given slowly through a vein (infusion). At the first visit, the study doctor will check if you can participate in the study. If you are eligible and enter the study, you will follow an assigned schedule and either start with BAX 930 (Period 1) and then switch to standard treatment (Period 2) or start with standard treatment (Period 1) and then switch to BAX 930 (Period 2). Everyone will be treated with BAX 930 again for Period 3. Each Period will last approximately 6 months. If you enter the study to control an acute TTP event, you will follow a schedule receiving either BAX 930 or standard care to treat your acute TTP event. Once the acute TTP event has gotten better, you can decide to continue in the study and be given treatment to prevent TTP events from happening, following the schedule above. Another study's aim is to assess side effects from treatment with BAX 930 and standard treatment. To do that, the study doctor will ask you questions about your health at each study visit. The study doctors will also check how long BAX 930 stays in the blood of the participants, over time. They will do this from blood samples taken after participants receive their specific infusions of BAX 930. This will happen at different times during the study. 1 month after all treatment has been completed, participants will visit the clinic for a final check-up.
The purpose of this study is to monitor the use in routine clinical practice of REKOVELLE®. This study will collect information from patients who never underwent previous in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatments for up to three consecutive treatment cycles. The ovarian stimulation protocol with REKOVELLE®, a new recombinant human Follicle Stimulating Hormone (FSH) prescribed for ovarian stimulation, is individualised with a dosing regimen that is based on two parameters: the body weight and the level of a hormone, the Anti Müllerian Hormone, (AMH), a parameter used to predict how the ovaries will respond to the ovarian stimulation.
Work place related (lower) back pain in medical personnel is limiting to workability. Even though occupational prevention programs are increasingly established, data on the effectiveness of training interventions offered at work-sites is largely missing. In this randomized, investigator-blind, controlled feasibility study we aim to compare the effectiveness of device assisted training therapy in comparison to a general recommendation "to stay active" or group gymnastics in terms of pain frequency and intensity (main outcome). Additional outcome variables are: quality of life, psychological well-being, work efficiency, of sick-leave days. Eligible employees (2 x 30) of the General Hospital of Vienna (AKH) over the age of 45 years suffering from (lower) back pain (>30 days/last year) of intensity ≥ 3 (numeric scale 0-10) will be included in two parallel groups. Group I starts with a device (DAVID) assisted training (40 training sessions; 2x / week) of the core trunk musculature. Group II gets instructions and an advice on how to "stay active" during the first 6 months. Assessment will be conducted before and after these 6 months; then groups are switched, thus, study subjects act as their own controls.
It has been recognized lately that sepsis and inflammation has an important impact on lipid metabolism and that the extent of hypocholesterolemia may even be a marker of severity of illness. However, the interplay between inflammation and the marked changes in lipid metabolism remain to be sufficiently understood. Importantly, the exact kinetics of lipid parameters in inflammatory conditions are yet to be explored. This study aims to investigate the interaction between inflammation and lipid metabolism using the human endotoxin model (LPS infusion) in ten healthy volunteers in a single blinded randomized placebo controlled cross-over design.
