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.
60% of all malignant diseases occur in patients who are 65 years or older. For these patients, aggressive treatments are often not suitable due to reduced life-expectancy, reduced general condition, comorbidities, and reduced vital functions which can lead to increased adverse effects of chemotherapy. Therefore, it is important to investigate alternative therapy options for elderly patients. Erlotinib is an orally applied medication which is associated with reasonable toxicity. This targeted agent may prove an effective and well-tolerated first-line therapy in elderly patients with advanced non small cell lung cancer. Therefore, the aim of this study is to investigate the progression-free survival of the combination of vinorelbine and carboplatin in comparison to erlotinib. Given that there will be no significant reduction of efficiency this may provide elderly patients of more than 70 years of age with an active oral substance without subjecting them to the sometimes severe adverse effect of the chemotherapy.
Background: During the repair process of deep venous thrombosis, capillary formation is seen from day 18 to day 25. Contrast agent investigation is well known to detect small vessels in arterial disease. We intend to use this method to detect early vascularisation in the thrombus, in order to get more information about the evolution of the thrombosis in vivo. Aims of the study: Investigation of a newly diagnosed occluding venous thrombus with duplexsonography, using contrast agent and compare the degree of vascularization in the same patient after 3 weeks and 3 months. The relative signal intensity difference (baseline to peak) of the time intensity curve (TIC) is measured in defined region of interests (ROI). Comparison of the visibility of revascularisation between color duplexsonography, power mode and contrast agent will be done. Method: Patients with venous thrombosis of the proximal limb veins (femoral or popliteal vein) will be investigated with ultrasound agent in supine position. 5 ml of the contrast agent sulfur hexafluoride is given intravenously into a vein of the dorsal foot. The measurements are done in a defined area, where the thrombus is fully occluding in color Doppler investigation. The regions of interest will be the vessel walls and the centre of the thrombus in cross section view. The signal intensities are measured at baseline and peak (in decibel) in the centre and in the peripheral part of the vein. 20 patients with acute deep venous thrombosis will be included in this pilot study and investigated at baseline, after 3 weeks and 3 months. Previously (before contrast agent application), the veins are investigated with color - and power Doppler to test visibility in comparison to the contrast agent investigation.
This study will assess whether an implantable defibrillator will increase the likelihood of survival in patients who have had a heart attack, have abnormal test results from a 24 hour heart monitor, and who have low normal heart function.
The pathogenesis of adrenal tumors is still not fully elucidated and the treatment options for malignant tumors are poor. The current study investigates different aspects of the pathogenesis of adrenal tumors and evaluates different therapeutic options in patients with adrenocortical carcinoma.
The purpose of this study is to determine whether combined chemotherapy [rituximab plus high dosage methotrexate (max. 2 cycles) followed by arabinoside/thiotepa (max. 2 cycles) followed by high dosage carmustin/thiotepa] followed by peripheral blood stem cell transplantation is effective in the treatment of cerebral Non Hodgkin lymphoma [PCNSL].
The aim of the study is to examine whether the efficacy of psychoeducation in patients with schizophrenia or schizoaffective disorders is dependent on their cognitive performance level and if a preceding cognitive training can enhance the therapeutic effects of psychoeducation
The purpose of the study is to investigate whether insulin sensitivity of the human brain correlates with insulin sensitivity of the liver.
The main objective of this study is to assess the safety and effectiveness of the TiN-coated MAR-Tyn stent in maintaining minimum lumen diameter in de novo native coronary artery lesions as compared to an uncoated control cobalt-chromium balloon-expandable stent (Vision, Abbott Vascular). Both stents are mounted on a Rapid Exchange Stent Delivery System.
Recognition of disease specific clusters of volatile organic compounds in patients with different lung diseases, using breath analysis with ion mobility spectrometry. Lung diseases of interest are: - COPD - tumors - airway infection - interstitial lung disease - sleep apnea Hypothesis: Breath analysis with ion mobility spectrometry can differentiate pulmonary disorders.
The trial will evaluate the effects of frequent exercise and increased mental activity on the age-related impairment of cognitive function in elderly women. Furthermore, we will assess the effects of exercise and mental activity on the mood, physical performance and mental status of participants. We will also search for genetic factors which may be responsible of the observed outcomes.
