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.
The purpose of this study is to evaluate the influence of alendronate therapy on the wound healing after dental implants in patients with osteoporosis.
Peripheral T cell lymphomas comprise 10-15% of all malignant lymphomas. The prognosis is significantly worse than that of aggressive B cell lymphomas. The prospects of elderly patients are especially poor, with an estimated disease free survival of only 25% after three years. Previous phase II trials have demonstrated a significant activity of the monoclonal anti CD52 antibody alemtuzumab in primary and relapsed T cell lymphoma. The investigators thus propose to investigate the value of adjuvant alemtuzumab in combination with dose dense CHOP-14 in patients with previously untreated peripheral T cell lymphoma.
1. Does primary stenting have a lower 12-month restenosis rate than PTA alone in the treatment of atherosclerotic lesions of the popliteal artery? - Alternative hypothesis: "Primary stenting with the Edwards LifeStent is associated with a lower restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery at 12 months" - Null hypothesis: "Primary stenting with the Edwards LifeStent is not associated with a lower 12-month restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery"" 2. Does comparison of the two intervention groups (PTA alone, stenting) disclose differences in terms of the secondary endpoints? 3. How do the intervention methods compare in terms of safety/incidence of adverse effects? 4. What are the long-term clinical implications of the two treatment methods?
The study aims to evaluate the course of patients with acute pancreatitis. Thereby we analyze different diagnostics and compare ultrasound, MRI and CT-scan in detection of necrotic areas and evaluate interventional therapy methods like percutaneous drainage techniques regarding the outcome. Laboratory values were assessed as well.
Simultaneous radio-chemotherapy in advanced non-small cell lung cancer. The study focusses on a randomised comparison of conventional radiotherapy planning with irradiation of macroscopic tumor and lymph nodes together with prophylactic target volumes vs. irradiation only of FDG-positive lesions. Primary endpoint is the local disease control in the chest.
The study will be performed as a randomized, double blind trial (in respect of the primary end point) with treatment of the stenotic lesion using uncoated PTA-catheters as control group. 114 patients will be included in the trial at about 5 study centers. Follow-up includes control angiography after 6 and 18 months and clinical follow-up examinations up to 18 months. Primary objective: Efficacy of paclitaxel coated PTA balloons in inhibiting restenosis of below the knee arteries (late lumen loss) Secondary objective: Various angiographic and clinical efficacy measures, safety and tolerance of pacli-taxel coated PTA balloons in inhibiting restenosis of below the knee arteries Descriptive statistics, comparison by t-test, chi-square test for binary events 10.1 Descriptive statistics As far as applicable descriptive statistics will be applied to data and will be referring to individual changes versus baseline (predilatation or immediately postdilatation). The groups will be compared to each other testing the statistical significance of differences (p ≤ 0.05). Con-tinuous data will be expressed as mean ± standard deviation. Categorical variables will be compared using the chi-squared test, and continuous variables will be compared using Student's t test or ANOVA analysis. In addition to the assessment of the primary endpoint and the secondary endpoints a multi-variate analysis to investigate the influence of risk factors on the interventional outcome (interventional success, early restenosis/occlusion, LLL, stent integrity) and clinical outcomes will be performed. For this analysis the following factors will be considered: age, diabetes, neurological status (only Rutherford 5), lesion length, grade of dissection and calcification, reststenosis, number of run-off vessels, stent administration in the index lesion(s). 10.2 Estimated number of patients The primary endpoint of the study is late lumen loss (LLL) at 6 months evaluated by quantitative angiography. Because no data according this endpoint are available for both the control group and the group which will be treated with the paclitaxel coated balloon an assumption according the LLL at 6 months was made according the expectations of the principle investigator. An estimate for LLL as % of MLD in the control group is 50% and in the drug coated balloon group 30 %. The standard deviation is calculated to be 30% of LLL. A sample size of 37 patients in each group will allow the detection of a statistically significant difference (p<0.05) with 80% power. Based on the "Below study" which enrolled patients with comparable arterial lesions in Tuebingen and the data of the Basil study, it is estimated that 35% of the patients who will be enrolled in the study will not be available for follow-up investigations in order to calculate the MLD. In order to meet a statistical endpoint a total of 114 patients will be enrolled.
The Geriatric Center Ulm scientifically supported a three-year pilot study (ProjektDEMENZ Ulm), in which numerous findings on the system of care regarding people suffering from dementia and their relatives were determined. One of the most important conclusions is the significant lack of information on the well-functioning network of the care system in Ulm. The full potential of the network is not being exploited. The situation in the Alb-Donau-Kreis - the area surrounding Ulm - is very similar. The investigators' aim is to improve the utilization of the system of care for those suffering from dementia in Ulm/Alb-Donau-Kreis by using a newly designed advisory approach (Lighthouse Project on Dementia, Ulm, ULTDEM study). The purpose of the study is to prove the effectiveness of this procedure by using a prospective, open, randomized, controlled, interventional study. After the randomization, the interventional group is given comprehensive, individual advice about available treatment possibilities for people suffering from dementia. In addition, they have the opportunity to re-evaluate their present diagnostic procedure. The participants of the control group receive the standard treatment. Inclusion criterion is the application of a care level ( level 0 or 1). Recruitment will take one year. A final assessment will be taken every six months.
The purpose of this study is to define if palliative surgery in patients with cancer improves quality of life and prognosis.
The purpose of this study is to test a combination-therapy of oxaliplatin and docetaxel in patients with metastatic or locally advanced adenocarcinoma of the pancreas after failure of a palliative first line therapy.
Environmental risk factors for the development of schizophrenia include infections during the perinatal period or later in life with Toxoplasma gondii (TG) being one of the candidate agents. A recent review (Torrey and Yolken, 2003) on TG in schizophrenia and other serious mental disorder reported higher antibodies to TG in patients compared to controls in 18 of 19 studies, one having been conducted by the investigators group. In a second, independent study on first-episode schizophrenia (n=56) and control subjects (n=32), sera were sampled and standard instruments used to assess diagnoses and psychopathology, respectively to screening controls. For the total sample, contacts with animals during pregnancy and age emerged as a non-significant predictors of TG IgG titers. Means of patients' and controls' TG IgG titers did not differ significantly but variances did; a subgroup of patients' titers reached much higher levels than those of controls. Patients in the high TG IgG subgroup were older (p=0.001), also they were older when psychiatric symptoms appeared, more individuals had regular animal contacts during pregnancy, or rural upbringing including regular animal contact, more consumption of raw meat, and a higher absolute treatment response (all trend levels). Regarding the short term course of patients, the investigators detected decreasing IgG titers in several individuals A power analysis demonstrated that results fell short of significance due to lack of statistical power. Based on the power analysis, the investigators propose an opel label, multicenter study at three regionally different sites within Germany (Halle, Hamm, Heidelberg). The investigators intent to study 173 first-episode patients with schizophrenia, schizoaffective, and schizophreniform disorder and 173 matched controls. The investigators hypothesize that - according to the heterogeneity of the illness - a subgroup of patients will exhibit higher TG IgG titers compared to the remaining patients and to controls; that this subgroup will have had regular contact with animals during pregnancy and early life as well as developmental delays; and that clinical improvement, response to treatment, and subjective well-being will run parallel with TG IgG decrease. Patients shall be assessed on admission to hospital, at discharge and at 6- and 12-month-follow-up with respect to TG antibody titers, symptomatology, neuropsychology, predictors of outcome, quality of life, and neurological soft signs. In controls two assessments shall be performed, 12 months apart. All foreseen assessments will be performed using standard measurement instruments with sound reliability and validity such as the SCID and the PANSS. Exposure to cats, other warm-blooded life-stock, and raw meat will be assessed using a special questionnaire.
