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.
Thrombolysis using Alteplase (tPA) is still the only approved specific therapy for acute ischemic stroke (AIS). Current guidelines in western countries recommend an tPA dose of 0.9mg/kg up to a maximum dose of 90mg for patients weighing more than 100kg. However, larger dose-finding rtPA trials for intravenous thrombolysis in AIS are missing. Based on results from research on myocardial infarction only a few open label studies with low case rates were initiated to evaluate the optimal dose for tPA in cerebral ischemia. These studies suggested a narrow therapeutic range with decreased efficacy in lower dosages and an increased risk for thrombolysis related intracerebral hemorrhage (ICH) at doses above 0.95mg/kg. The ECASS-1 trial which used a dosage of 1.1mg/kg rt-PA showed significantly higher rate of large parenchymal hemorrhages compared to trials using 0.9mg/kg. Therefore accurate dosing is crucial. In the acute phase two aspects complicate rtPA dosing in AIS: First, unlike in other diseases many stroke patients are unable to communicate information on their body weight (BW) because of their stroke symptoms (e.g. aphasia, decreased consciousness). In addition motor symptoms prohibit easy weighing procedures in many patients. Second, the ultra-early and narrow time window for treatment does not allow time loss to weigh each patient in the emergency situation. Therefore routinely the attending physician has to make a visual estimation of the patient's BW. This may be inaccurate and may cause dosing errors which has been shown for other weight based emergency medication. There is little data on tPA-dosing errors in stroke patients and prospective data are lacking. The aim of our study is to evaluate availability of BW-information, accuracy of estimations and final dosing of tPA in a routine clinical setting. Therefore the investigators evaluate different sources of body weight estimations and also compare visual estimation with recently proposed anthropometric measurements for body weight approximation. Finally, impact of dosing errors on safety and efficacy are analyzed. The initial phase will consist of 100 enrolled patients as a pilot phase for further power calculations. Based on the results of the pilot phase enrollment will continue. The envisioned inclusion target is up to 800 patients.
Define maximum tolerable dose of the combination lenalidomide, bendamustine, prednisone.
The researchers will investigate whether caloric restriction or dietary supplementation could provide positive effects on general brain functions in healthy elderly people.
Patients with bilateral heterogeneous pulmonary emphysema benefit to differing degrees from unilateral ELVR with complete lobe closure in comparison with incomplete bilateral treatment.
Disease related biomarkers have been established decades ago, e.g. blood glucose for diabetes diagnosis and management. Their discovery has grown dramatically during the past decade and they have the potential to lead the physician in diagnosis -especially differential diagnosis - and therapy. However, a specific serum-biomarker in lung diseases has not been established. Aim of the current study is to to measure lung specific proteins in the serum in patients with various lung diseases and to correlate those with disease severity, lung function and other laboratory results
The purpose of this study is to determine whether combined chemotherapy [rituximab plus high dosage methotrexate, lomustine, and procarbazine] followed by maintenance therapy with procarbazine is effective in the treatment of cerebral Non Hodgkin lymphoma [PCNSL] in patients > 65 years.
The purpose of the study is to evaluate the efficacy of stenting after dilation with or without paclitaxel-eluting balloon or atherectomy in patients with symptomatic peripheral artery disease.
The purpose of this study is to perform molecular diagnostic in mediastinal lymph nodes of non-small cell lung cancer patients sampled by endobronchial ultrasound guided finde needle aspiration (EBUS-TBNA).
The purpose of this study is to analyse the physical and psychological side-effects in the course of treatment with IFN-alpha. The effectiveness of a specific intervention for the management of these side-effects is evaluated.
Starches from genetically modified potatoes, which differed in terms of amylose, amylopectin and phosphate content, were tested in a human randomized controlled trial.
