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.
Heart-surgery with the use of a heart-lung-machine can trigger the development of a full-blown SIRS (Systemic Inflammatory Response Syndrom) with multi organ failure and severe sepsis in the course of disease. For the treatment of full-blown SIRS extracorporeal treatment like the Cytosorb-Adsorber are in clinical testing. The Cytosorb-Adsorber is a CE-signed medical device with approval for the treatment of severe sepsis and hyperinflammation. The adsorber remove not-specific cytokines and other inflammation mediators from the patients blood. In this study (as a case-observation and compassionate use) the effect of extracorporeal treatment with the Cytosorb-Adsorber for the reduction of postoperative hyperinflammation and SIRS after heart-surgery with use of a heart-lung-machine will be observed. The aim of the study is recording the influence of the treatment with the Cytosorb-Adsorber on the course of hyperinflammation and multi organ failure in comparison with a historic control group.
The purpose of this prospective, non-interventional study is to validate the Narrow Band Imaging International Colorectal Endoscopic (NICE) classification for differentiating subcentimetric hyperplastic and adenomatous polyps by using Fuji Intelligent Color Enhancement (FICE) technology with high-definition without optical magnification.
The aim of this prospective study is to examine the benefits and risks of administration of local anaesthetics with a special atomizing set (Enk Fiberoptic Atomizer, Cook Medical) during flexible bronchoscopy.
Longterm disease-free survival (DFS) of older patients with acute myeloid leukemia (AML) remains poor. The vast majority of AML patients relapses within two years after start of therapy1,2. In Acute Promyelocytic Leukemia (APL, AML M3), all-trans-retinoic-acid (ATRA; Tretinoin) induces differentiation and subsequently clinical remission. So far effective differentiation therapy does not exist in other AML subtypes. Recent preclinical data suggest that the combinatorial use of ATRA and tranylcypromine (TCP), an irreversible Monoamine-Oxidase (MAO) and Lysin-specific demethylase (LSD) inhibitor that also inhibits LSD1 (a histone H3 Lysine 4 demethylase), induces leukemia cell differentiation and leukemic stem cell exhaustion in vitro and in vivo in non-APL AML subtypes. In this Phase I/II study the investigators will explore the feasibility, safety, as well as efficacy and of Tretinoin/TCP treatment in patients with relapsed or refractory AML or in patients with AML who are not eligible for intensive treatment. Patients will be treated with daily increasing doses of TCP (initially 10 mg/day, then +10 mg each day up to 80mg/d). After 7 days, ATRA will be added at a fixed dose (45 mg/sqm/day). Overall, 16 evaluable patients are going to be treated. The primary endpoint is the fraction of patients that achieve CR, CRp( complete response with incomplete recovery of platelets), CRi (complete response with incomplete recovery of granulocytes) and PR. Secondary endpoints are tolerability, safety as well as progression-free survival and overall survival. Serum levels of TCP will be regularly analyzed. Pharmacodynamic analyses will be performed with analyses of the inhibition of LSD1 by TCP. Further analyses will address the changes in Histone H3 lysine 4 tri demethylase (H3K4me3) levels in AML blasts and the differentiation status of AML blasts. Taken together, this Phase I/II study will analyze feasibility, pharmacodynamics and effectivity of ATRA and TCP as differentiation therapy in AML.
Retrospective non-randomized in-vivo comparison of different levels of femoral rollback in the ATTUNE total knee arthroplasiy system (rotating platform CR high level roll back vs. rotating platform CR low level roll back) on the basis of fluoroscopic and marker-based motion capture evaluation. How do different levels of intra-operatively observed femoral rollback correlate to postoperative kinematics under weight bearing conditions? Does the modified design of the Attune Knee System influence the extent of the femoral rollback compared to the PFC Sigma Knee System? Does the femoral rollback maintain over a period of 12 months follow up or is it reduced by, for example, remodelling of the posterior cruciate ligament?
Surgical incision for plate osteosynthesis of midshaft fractures of the clavicle averages 7 to 8 centimeters in the literature. It is hypothesized, that depending on the invasiveness of this incision secondary problems like prolonged fracture healing, paresthesia of supraclavicular nerves and pain due to scar tissue increase. Therefore we developed a mini-incision technique using an average incision length of 4cm. The aim of this study is to analyzed whether secondary problems following plate osteosynthesis of the clavicle correlate mit the length of the surgical access.
This study aims to proof the efficacy of a cognitive rehabilitation program for patients with mild dementia in Alzheimers Disease with respect to activities of daily living.
For patients with emphysema lung volume reduction (ELVR) could be an expedient approach for the reduction of distension of the lung. ELVR may be performed using RePneu® Coils. After the insertion of the coils distended lung sections shrink so that healthy parts can expand. In the present study investigators intend to examine, whether the insertion of the coils improves diaphragm function and force of the breathing muscles. Investigators hypothesize that reduction of lung volume eliminates or reduces flattening of the diaphragm and relieves breathing muscles, respectively respiratory pump, which aims to reduce dyspnea.
Arrhythmias of the atria of the heart are a common comorbidity in patients with cardiac rhythm management devices, such as pacemakers and implantable cardioverter/defibrillators (ICD). External electrical cardioversion is an established method to achieve rhythm control (restore normal sinus rhythm) in patients with atrial arrhythmia. Little data on safety and efficacy of external electrical cardioversion in patients with cardiac rhythm management devices exists. Thus, available data on the safety of external electrical cardioversion in cardiac rhythm management patients lacks statistical power to accurately reflect the true hazard of external electrical cardioversion in patients with cardiac rhythm management devices. The aim is to systematically include and follow all patients with cardiac rhythm management devices presenting for external electrical cardioversion, to analyse the effects of external electrical cardioversion on leads and devices.
The study evaluates the ABCB1-genotype dependent efficacy of a quick dose-escalation strategy within 28 days of treatment with approved antidepressants that are known substrates of the P-glycoprotein, an efflux pump of the blood-brain barrier expressed by the ABCB1 gene. Moreover, the study evaluates ABCB1-genotype dependent side-effects of approved antidepressants that are known substrates of the P-glycoprotein, an efflux pump of the blood-brain barrier expressed by the ABCB1 gene.
