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 date the standard non-surgical treatment strategy for treating un-ruptured intracranial aneurysms is the use of either coils or self-expandable stents. This post-market clinical investigation compares the efficacy of using the CE-marked, commercially available SILK Artery Reconstruction Device against commercially available intracranial coils in the endovascular treatment (occlusion) of intracranial aneurysms.
The aim of this study is to perform a randomized, controlled trial to compare percutaneous transluminal angioplasty using paclitaxel eluting balloon (PEB) or using a conventional balloon for treatment of superficial femoral artery in-stent restenosis.
Sudden cardiac arrest (SCA) remains one of the major leading causes of death. Cognitive deficits are common in survivors of SCA. Postresuscitative mild induced hypothermia (MIH) lowers mortality and reduces neurologic damage after cardiac arrest. The investigators evaluated the long term neurological outcome after mild hypothermia after restoration of spontaneous circulation.
A study of non-inferiority design comparing brilliant blue and indocyanine green as intraoperative dye in macular pucker and macular hole.
Hypothesis: Endosonography (EUS) in a single setting is equivalent to the standard algorithm combining abdominal sonography, gastroscopy, endosonography in patients with acute right side abdominal pain. Patients with acute right side abdominal pain will be randomized in one of two groups. In each group all examinations (sonography, gastroscopy, endosonography) will be performed. The study group only defines the order of the examinations. Abdominal sonography will always be performed before endoscopic procedures. In group 1, gastroscopy is first followed by endosonography. In group 2 endosonography is first followed by gastroscopy. Two physicians will review all results of all examinations, patient charts as well as a follow up visit and establish a clinical diagnosis. Yield of the clinical diagnosis by EUS results alone will be compared to the yield by combined results of sonography, EGD and EUS.
Improvement of the clinical outcome in patients with resectable pancreatic carcinoma through an intensified adjuvant treatment with gemcitabine, cisplatin and regional deep hyperthermia as compared to standard chemotherapy.
The varenicline for alcohol dependence trial investigates the efficacy of varenicline versus placebo for maintaining abstinence in the postacute treatment of alcohol dependent subjects. The main study hypothesis is that subjects treated with varenicline have more abstinent days during the study.
To evaluate the role of the LungPoint VBN System in the bronchoscopic access to a target location. The evaluation will explore: - Ability of the system to guide a user to one or more target site(s) - Ease of use of the system (assessment of the user interface) - Incremental value brought by the use of the system to the successful completion of a case.
Vasculitis is group of diseases where inflammation of blood vessels is the common feature. Patients typically present with fever, fatigue, weakness and muscle and joint aches. These symptoms are very common among many different diseases, not just vasculitis. A clustering of other symptoms, physical examination findings, blood tests, radiology and biopsy help make the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis when a patient presents with these non specific symptoms and they are reliant on previous experience and disease definitions. One of the aims of this project is to develop diagnostic criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis, Takayasu arteritis). We, the investigators, will do this by studying a large group of patients with vasculitis and comparing them to a large group of patients that present in a similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of items to differentiate between vasculitis and 'vasculitis mimics'. We also aim to update the current classification criteria. Classification criteria are used to group patients into different types of vasculitis, once a diagnosis of vasculitis has been made, and are useful for studying patients in clinical trials with similar or identical diseases. The current classification criteria (American college of Rheumatology 1990 criteria) were developed 20 years ago, before the availability of some important diagnostic tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with some of the current disease definitions. Therefore to progress future research in vasculitis, it is important that the classification criteria are updated. We will recruit 260 patients with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the 5 other types of vasculitis), in order to determine the optimal combination of symptoms, signs and investigations that classify each person into the appropriate group.
In experimental and clinical settings it has been shown that transplant tolerance is possible. It has been suggested that regulatory T cells play a beneficial role in the establishment of tolerance. Calcineurin inhibitors may inhibit development of regulatory T cells. However, the influence of calcineurin inhibitors on markers of transplant tolerance has not been studied in patients undergoing liver transplantation. Currently the investigators conduct a study to evaluate the safety and efficacy of a calcineurin inhibitor free immunosuppression in patients undergoing liver transplantation. In this study measurements of immune function and CD4+CD25high-Foxp3+-Il2/CD8+ status will also be performed. In parallel these measurements should be compared to a group of patients undergoing standard immunosuppression including calcineurin inhibitors.
