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.
More than 80% of the population in the USA consume coffee each day. However there not many studies on change of heart rate variability and placebo effects after consumption of coffee. In our study we aim to test the following hypotheses: 1. Habitual caffeinated espresso coffee drinkers show an increase in blood pressure, heart rate variability and parasympathetic activity (high frequency band) of the heart. 2. Non-habitual caffeinated espresso coffee drinkers show an increase of blood pressure. The heart rate variability and the parasympathetic activity of the heart will decrease. 3. Caffeinated or decaffeinated espresso induces comparable changes in habitual or non-habitual coffee drinkers.
The aim of this study was to determine the effectiveness of endoscopic full-thickness plication (Plicator; NDO Surgical, Inc., Mansfield, MA) for the treatment of GERD in comparison to a sham procedure. Patients with symptomatic GERD requiring maintenance proton pump inhibitor therapy were entered into a randomized, single-blind, prospective, multicenter trial. Seventy-eight patients were randomly assigned to undergo endoscopic full-thickness restructuring of the gastric cardia with transmural suture. Eighty-one patients underwent a sham procedure. Group assignments were revealed following the 3-month evaluation. The primary endpoint was ≥ 50% improvement in GERD-HRQL score. Secondary endpoints included medication use and esophageal acid exposure. Patients achieving ≥ 50% improvement in GERD-HRQL score at 3-months versus baseline off-meds were considered responsive to their assigned procedure. Patients who failed to reach this level of improvement at 3-months were considered non-responders. Analysis of these dichotomized variables (responder/non-responder) was done using Fisher's exact test comparing the proportion of responders between the active and sham groups. Intent-to-treat analysis was also performed. The null hypothesis was that the proportion of responders was the same in both the active and sham groups. Testing was done at the 5% level of significance (alpha=0.05).
The main objective of the study was to evaluate the effectiveness of aflibercept treatment by comparison to placebo in increasing the overall survival (OS) in participants with metastatic pancreatic cancer, treated with gemcitabine. The secondary objectives were to evaluate progression free survival, clinical benefit, overall response, safety and immunogenicity of aflibercept, in the two treatment arms (Arm 1: Aflibercept and Gemcitabine; Arm 2: Placebo and Gemcitabine). The study included an interim analysis of OS. In accordance with the study protocol, an interim analysis was performed for the purpose of futility and overwhelming efficacy. On the basis of the interim analysis, the Data Monitoring Committee (DMC) recommended that this study be terminated for futility based on predefined boundary rules.
The study is conducted to compare safety and efficacy of isoniazid administered as an adjusted dose based on NAT2 (arylamine N-acetyltransferase type 2)genotype and as a standard dose. The hypothesis is that the genotype-adjusted dose is superior to the standard dose with regard to hepatotoxicity and early treatment failure, respectively, in the group of slow and rapid acetylators of NAT2.
To evaluate the benefit of rituximab in patients with CAN with histologically proven C4d deposits and/or plasma cell and/or B-Lymphocyte (CD20+ cells) infiltration of their grafts.
This is a randomized, double-blind, placebo-controlled, multi-center, sequential cohort study in subjects with congestive heart failure (CHF) and impaired renal function who are on stable furosemide treatment (³ 40 mg daily). A total of 50 subjects will be randomized to each increasing dose level of SLV320 or placebo in a sequential fashion.
The purpose of this study is to prove the findings of a preliminary study which strongly suggest the hypothesis that the result of conventional embolectomy for acute, severe lower-limb ischemia can be improved by controlled reperfusion.
Summary: The investigators aim to identify markers of right ventricular dysfunction in patients with severe pulmonary regurgitation following repair of Tetralogy of Fallot, that allow prediction of the optimal timing of the replacement of the regurgitant valve. The investigators will use MR as a gold-standard reference for measurement of cardiac function during rest and dobutamine stress. The investigators will also evaluate the predictive potential of tissue Doppler imaging in this patient group. Purpose: To predict the optimum timing of pulmonary valve replacement for severe regurgitation in repaired Tetralogy of Fallot using Cardiac Magnetic resonance with dobutamine stress testing.
Several combinations of H5N1 antigen concentrations and aluminium-hydroxide adjuvant concentrations will be tested for their safety and capacity to induce a specific immune response.
The IMPACT Study will investigate the potential clinical benefit of the combined use of BIOTRONIK Home Monitoring (HM) technology and a predefined anticoagulation plan compared to conventional device evaluation and physician-directed anticoagulation in patients with implanted dual-chamber defibrillators or cardiac resynchronization therapy devices.
