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.
To proof patients' benefit of minimally invasive surgery in the dorsal cervical spine an apparatus to examine head-neck-coordination was constructed. Two different surgical techniques will be compared: Laminoplasty: open approach vs minimally invasive surgery (MIS)-approach; Foraminotomy: open approach vs MIS-approach. Each patient will be tested before surgery, postoperative as well as 3 and 12 month follow-up. Hypothesis is that patients after MIS-approaches perform better in their head-neck-coordination as patients with open approaches.
To demonstrate the use of WavSTAT4 system during colonoscopy in identifying diminutive colorectal lesions (e.g. hyperplastic polyps) that can be resected and discarded (or even left in-situ) without adverse clinical impact.
The clinical study aims to investigate the numbers of predefined complications in the first six month after implantation of the implantable LENUS Pro® medications pump for intravenous application of treprostinil sodium in patients with PAH. The manufacturer is Tricumed GmbH, Germany; exclusive marketing rights: OMT GmbH & Co KG 78665 Frittlingen, Germany.
A prospective observational multi-centre study for the validation of the ApneaScan algorithm (integrated in ICD devices (with or without cardiac resynchronization therapy function) of the "Incepta" series for the screening of sleep disordered breathing in patients with stable symptomatic chronic heart failure, using portable polygraphy monitoring device ("Embletta Gold") as reference for the Apnea-Hypopnea-Index (AHI). Secondary objectives are the detection of severe sleep disordered breathing in patients with clinically indicated in-laboratory polysomnography, as well as correlations of the AHI detected by ApneaScan with other clinical endpoints like mortality, hospitalization, atrial fibrillation and ventricular arrhythmia.
The goal of this observational study is to evaluate the toxicity and local tumor control of proton therapy for patients with head and neck cancer in a previously irradiated field. Standard of care for recurrent or secondary malignancies in a previously irradiated field is surgery. For inoperable patients or residual tumor after surgery, standard of care would be palliative chemotherapy. For a small subset of patients (good performance status, small radiation fields) re-irradiation can be performed. In this study the established concept of re-irradiation with photons will be transferred to proton radiotherapy. Proton therapy has the advantage of a steeper dose gradient to normal tissues, thus-theoretical advantages for lower toxicity.
The aim of the study is the evaluation of the ablation efficiency of the percutaneous irreversible electroporation (IRE) as primary ablation therapy of locally confined renal cell carcinoma (≤4cm, see inclusion and exclusion criteria). The ablation success will be proofed by magnet resonance imaging (MRI) and histologically after partial kidney resection or nephrectomy 4 weeks after IRE. Hypotheses: Kidney tumors ≤4cm can be ablated completely by percutaneous IRE. Surrounded structures and renal tissue can be preserved.
It has been shown, that in patients with very severe chronic obstructive pulmonary disease (COPD) the additional use of non-invasive ventilation during pulmonary rehabilitation (PR) may enhance the benefits of PR. It is assumed that the non-invasive ventilation techniques provides a better recovery of the respiratory pump during the night. If non-invasive ventilation also decreases the metabolic demands during night is unknown and is aim of this study. During a 3 week inpatient pulmonary rehabilitation program a total of 85 patients with chronic obstructive pulmonary disease stage IV will be recruited for this study. There will be a 4:1 distribution into 2 groups. 68 patients with an indication for the use of a non-invasive ventilation will be involved in the intervention group where non-invasive ventilation will be initialized. 17 patients with chronic obstructive pulmonary disease stage IV without an indication for the use of non-invasive ventilation will be involved in a control group to detect the changes in nocturnal energy expenditure produced by pulmonary rehabilitation alone. All outcome measurements will be performed during day 1-3 and will be repeated after 12 days (with or without non-invasive ventilation) at day 15-17 of the pulmonary rehabilitation program. A sub-trial of this study is to validate night movement accuracy of the Dynaport activity monitor with the observations made by a night-vision camera in the sleep lab. This will be performed in study participants as well as in healthy volunteers.
The primary objective of this prospective, Randomized, Controlled, Multicentre, Open Study is to investigate the inhibition of restenosis by the Paclitaxel-eluting Percutaneous transluminal angioplasty (PTA) balloon Freeway versus PTA alone in the treatment of de-novo occluded, stenotic or reoccluded, restenotic superficial femoral (SFA) or popliteal arteries.
This study aims to characterize Usher patients in order to correlate this data with genetic information. Tasks: - Standardization and improvement of Usher syndrome diagnosis: refine and elaborate special tests of visual and otological function in association with genotype that enable to determine the most significant markers for Usher disease progression and therapeutic effect. - Perform genotype and phenotype correlations in Usher syndrome patients - Develop and maintain database for phenotypically and genotypically well-characterized patient cohorts, suitable for future therapeutic trials
Randomized clinical outcome study of two rotating hinge knee prosthesis in knee surgery. Hypothesis: No difference in the clinical outcome for 1 year after the operation. Clinical follow-ups at 3, 10, 90 and 360 days after surgery. Measurement of clinical parameters
