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.
All patients with chronic HBeAg negative hepatitis B treated with nucleos(t)ide analogues, who discontinue treatment based in the criteria outlined in the EASL hepatitis B guidelines shall be included in the present study. The aim is to evaluate the clinical outcome (virological relapse, HBsAg decline) and associated virological and immunological parameters.
Atrial fibrillation (AF) is progressively common, and increases the risk of stroke five-fold. Oral anticoagulation is the mainstay therapy; however, it increases the risk of bleeding. Moreover, 30% with AF and at risk of stroke are not in relevant anticoagulation. The randomized PROTECT-AF trial has demonstrated the superiority of left atrial appendage occlusion (LAAO) as compared to warfarin for prevention of the combined endpoint of stroke, major bleeding and cardiovascular mortality. However, studies comparing LAAO to therapy with novel oral anticoagulants (NOAC) have not been carried out. This study aims to assess the effect of left atrial appendage occlusion (LAAO) to reduce the incidence of stroke, systemic embolism, major bleeding and all-cause mortality in patients with atrial fibrillation (AF) and a prior ischemic stroke or transient ischemic attack (TIA).
Prospective non-randomised trial investigating the effect of vaginal vault Suspension on urge symptomatology in female patients with pelvic organ prolapse
To assess the safety and performance of the VaSecure drug-coated PTA balloon catheter in the treatment of patients with Chronic Limb Threatening Ischemia (CLTI) of the lower limb below the knee (BTK)
The study will enable the clinical applicability of the multiple-spectral-sonography for detection of severe brain injury in ICU patients. For this, the ACG diagnostic system (Sonovum AG, Leipzig, Germany) should be used as additional diagnostic tool in prospective single-center study.
This study evaluates the use of an additional hemoadsorption device in adult patients undergoing veno-arterial extracorporal membrane oxygenation (ECMO) following cardiac arrest and cardiopulmonary resuscitation in respect to its effects on post resuscitation inflammatory syndrome. At implantation of the ECMO the participants are going to be randomized into a treatment and a control group. The first will be outfitted with a polymer-based adsorption device implemented in the extracorporal circulation established by ECMO for 48h, the control group is going to be treated by ECMO and standard intensive care alone. To detect any significant differences in terms of inflammatory response and patient outcome the investigators will regularly determine the blood levels of certain cytokines in fixed intervalls. In addition, the investigators are going to compare secondary clinical outcome parameters like organ disfunction and 30d mortality.
Acute kidney injury (AKI) is a common and major complication of cardiac surgery. The aim of this study is to evaluate the use of a fragment of proencephalin in plasma and other biomarkers as specific markers for early diagnosis of AKI and the need of renal replacement therapy after cardiac surgery.
Study ROR-PH-301, ADVANCE OUTCOMES, is designed to assess the efficacy and safety of ralinepag when added to pulmonary arterial hypertension (PAH) standard of care or PAH-specific background therapy in subjects with World Health Organization (WHO) Group 1 PAH.
Evaluation of clinical, therapeutic and prognostic relevance of new experimental results as well as optimization of therapeutic models and development of a new algorithm for therapeutic plan and therapy in patients with uterine neoplasm
There are large inter-individual differences in the bleeding pattern of patients with moderate or mild hemophilia. The major determinant of bleeding phenotype is the level of coagulant factor VIII or IX. In hemophilia A, studies addressing the association between factor VIII level and the clinical bleeding pattern yield conflicting results. In hemophilia B such studies have not yet been performed. The primary aim of this project is to analyze the association between factor VIII and factor IX levels and the bleeding phenotype. The secondary aim is to analyze potential differences in phenotype between hemophilia A and B. The project is a multicentre observational cohort study. We will include 500 patients with moderate or mild hemophilia A (FVIII 0.02-0.35 IU/mL) and 500 patients with moderate or mild hemophilia B (FIX 0.02-0.35 IU/mL) who are 12 to 55 years old. The main cohort study consists of clinical data collection, one blood sample and an online questionnaire for patients. Data will be collected on the nature and duration of all bleeding episodes, disease and treatment characteristics, physical activity level and musculoskeletal status. One blood withdrawal will be performed for centralized laboratory assays for FVIII or FIX levels (both one-stage and chromogenic assays) and genetic analysis for the most prevalent prothrombotic mutations. The online questionnaire for patients focuses on bleeds experienced in the past. A subset of 200 patients aged 24 years or older (100 with moderate or mild hemophilia A and 100 with moderate or mild hemophilia B) will be investigated in more detail by longitudinal data collection including analysis of physical joint status, MRI imaging of joints and biomarkers for joint damage. This longitudinal observation will consist of two time points that lie two years apart, allowing us to identify any changes that occur over the observed time period with respect to joint status.
