There are about 25560 clinical studies being (or have been) conducted in Germany. 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.
Giant cell arteritis (GCA) is the most common vasculitis in the elderly. Accurate diagnosis is of utmost importance in order to then initiate the necessary immunosuppressive therapy. For large-vessel GCA (LV-GCA) involving the aorta and its branches, FDG-PET/CT is the standard in imaging for diagnosis and is recommended by the guidelines. However, this only indirectly visualizes inflammation through vessel wall uptake of glucose. A new PET tracer, 68Ga-pentixafor, is used to visualize the chemokine receptor CXCR4. This receptor is expressed by cells of the immune system. In the context of inflammatory processes, upregulation of CXCL12, the ligand of CXCR4, occurs in affected tissues. The chemotactic effect of this ligand leads to the immigration of CXCR4-positive inflammatory cells into the inflamed area, which can be visualized by PET using the CXCR4-specific tracer 68Ga-Pentixafor. The value of CXCR4-PET should therefore be tested in the context of LV-GCA. This study tests the benefit of CXCR4 in therapy-naïve patients with suspected LV-GCA. For this purpose, patients will receive a FDG-PET and a CXCR4-PET for direct comparison. This is an imaging-only study. Therapy will not be affected by the study. The study is single-arm and not blinded.
Researchers are looking for a better way to treat people with heart failure. Heart failure is a condition which occurs when the heart does not pump blood as well as it should leading to shortness of breath, tiredness, and ankle swelling. The study treatment BAY1753011 is under development to treat heart failure. It is thought to reduce the action of a hormone called vasopressin that is naturally produced in the body. People with heart failure often have elevated levels of vasopressin. This is known to result in worsening of the heart failure condition. People with heart failure often also have reduced kidney functions. As kidneys play a role in removal of drugs from the body, reduced kidney function may result in higher blood levels of BAY1753011. The main purpose of this study was to learn how BAY1753011 moved into, through and out of the body in participants with different degrees of reduced kidney function compared to matched participants (age, gender, and weight) with normal kidney function. To answer this, the researchers compared: - the (average) total level of BAY1753011 in the blood (also called AUC) - the (average) highest level of BAY1753011 in the blood (also called Cmax) between the different groups with reduced kidney function (mild/moderate/severe) and the control group (normal kidney function). In addition, the researchers wanted to know how safe BAY1753011 was and the degree to which overt medical problems caused by it could be tolerated (also called tolerability) by the different groups of participants. These medical problems are also known as "adverse events". Doctors keep track of all medical problems that happen in studies, even if they do not think they might be related to the study treatments. All participants took a single dose of BAY1753011 in tablet form by mouth. Each participant was in the study for approximately 3 to 4 weeks, including an in-house phase of 5 days and 4 nights with one treatment day. During the study, the doctors and their study team: - did physical examinations - checked vital signs such as blood pressure, heart rate, body temperature and number of breaths within a minute (respiratory rate) - examined heart health using electrocardiogram (ECG) - took blood and urine samples - counted the number of toilet visits during the night
A post approval study to investigate the efficacy of daridorexant in subjects with insomnia and comorbid nocturia
The aim of this study is to demonstrate the non-inferiority (NI) of the immune response and evaluate safety of RSVPreF3 older adults (OA) investigational vaccine in adults 50-59 years of age (YOA), including those who are at increased risk (AIR) of respiratory syncytial virus (RSV)-lower respiratory tract disease (LRTD), versus adults >=60 YOA
This randomized study focuses on the diagnostic quality and safety of CO2 application as contrast medium through an innovative injector of AngioDroid in angiography interventions in patients with peripheral arterial occlusive diseases.
Clinical reasoning abilities can be enhanced by repeated formative testing with key feature questions. An analysis of wrong answers to key feature questions facilitates the identification of common misconceptions. This prospective, randomised, cross-over study assessed whether an elaboration task and individualised mailed feedback further improve student performance on clinical reasoning.
The purpose of this study is to evaluate the distribution of IncobotulinumtoxinA (Xeomin) in healthy subjects at different volumes, concentrations and doses when administered intradermally and subcutaneously using different delivery methods (conventional needle and microneedles).
This study analyses the impairment of colour vision during hypobaric hypoxia in volunteers of different groups.
It is the aim of the current (follow-up) project for the first time in post-COVID-19 patients who continue to complain of shortness of breath and for whom there is no other explanation than possibly proven diaphragmatic weakness, to determine the effects of 6 weeks of IMT/diaphragm training on diaphragm strength and shortness of breath.
In the study, the speech intelligibility in noise (Outcome) between a novel noise reduction algorithm (Intervention) versus the standard noise reduction (Comparator) will be tested in adults with a N3-N4 hearing loss (Population) using streamed signals via hearing aids.
