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 two curative treatment modalities for patients with HNSCC - primary chemoradiation (CRT) or primary surgery (often combined with postoperative (C)RT) - are both associated with serious side effects for which reason further stratification, optimization and personalization of treatment is urgently needed. As novel quantitative image analyses are a promising tool for further risk stratification, the investigators training a three-dimensional Convolutional Neural Network on 18F-Fluorodesoxyglucose (FDG) positron emission tomography (PET) imaging and clinical / histopathological data of a multicentric, retrospective cohort of 1200 patients treated with primary CRT and 800 patients treated with primary surgery at Charité and cooperation institutes in order to predict individual treatment-specific outcomes and identify patients with excellent outcome after primary CRT or primary surgery or unfavorable outcome for both. The trained algorithm of the artificial intelligence will be validated in a prospective trial to see if predicted loco-regional control and recommended treatment strategies are reliable. In total 250 curative HNSCC patients, treated with CRT or primary surgery, will be enrolled on this prospective validation trial with observational character, while biomarker, clinical and FDG-PET data are collected from these patients and follow-up visits will be concluded.
Following whole blood stimulation with mesenchymal stem cell derived exosomes, immune phenotype, cytokine release and mRNA expression patterns from critically ill patients with COVID-19 will be determined.
Antidepressant medication is established as an evidence-based, guideline-recommended treatment for Major Depressive Disorders. In the past decades, prescriptions of antidepressant medication have markedly increased, with a specific surge in maintenance prescriptions and therefore, long-term intake, despite guideline recommendations to discontinue antidepressant medication after maintenance therapy has been completed. Over half of fully remitted patients who attempt to discontinue their antidepressant medication report adverse discontinuation symptoms. For many patients, discontinuation symptoms are so severe, that they do not manage to complete their discontinuation attempt. While discontinuation symptoms, deterioration of depressive symptoms, and recurrence can result from pharmacological effects of antidepressant discontinuation, patients' expectations towards discontinuation are likely to play an essential role in occurrence, too. The aim of the present study is to explore the interplay of expectations and pharmacological effects in antidepressant discontinuation. Participants who fulfill German national S3 guideline recommendations will receive a 1:1 chance to either discontinue their antidepressant medication or remain on their antidepressant medication. In addition, participants' expectations are intended to be manipulated by varying verbal instructions using the open-hidden paradigm. Within the open trial arms, participants will receive full information about their treatment (i.e., high expectation). Within the hidden trial arms, participants will be informed about a 50% chance of discontinuing versus remaining on their antidepressant medication (i.e., moderate expectation). Participants will have a 1:1:1:1 chance of being allocated to 1 of the 4 experimental groups: open discontinuation (OD), hidden discontinuation (HD), open continuation (OC), or hidden continuation (HC) of their antidepressant medication. This preregistration is part of the collaborative research center (CRC) SFB/TRR289 which aims to characterize the psychological and neurobiological effects of treatment expectations on health outcome (https://treatment-expectation.de) and is funded by the Deutsche Forschungsgemeinschaft (DFG).
The aim of this study is to investigate the significance of intraoperative echocardiography on the surgical course and association with patient outcome. Of particular interest is the three-dimensional assessment of cardiac and valvular function. The patient course from surgery to the time of hospital discharge will be followed up.
This is a multi-part, randomized, double-blind, placebo-controlled Phase 2 clinical study comparing the safety and efficacy of bezuclastinib (CGT9486) plus best supportive care (BSC) with placebo plus BSC in patients with nonadvanced systemic mastocytosis (NonAdvSM), including indolent systemic mastocytosis and smoldering systemic mastocytosis, whose symptoms are not adequately controlled by BSC. This study will be conducted in three parts. Patients in Parts 1a, 1b and 2 will receive bezuclastinib or placebo, and may roll over onto Part 3 to receive treatment with bezuclastinib.
The purpose of this study is to assess respiratory variation of carotid doppler peak velocity (∆CDPV) for prediction of fluid responsiveness during major abdominal surgery.
This is an open-label, multi-center pivotal Phase 3 study to visually and quantitatively assess PET images obtained after single application of 300 MBq [18F]florbetaben and PET scanning of patients with suspected cardiac amyloidosis.
This study is designed to determine the feasibility, safety, tolerability and maximum tolerated dose of Venetoclax in combination with Blinatumomab and to evaluate the response in patients treated with the combination of Venetoclax and Blinatumomab in in patients with hematological relapse or molecular relapse.
The aim of this post-market clinical follow-up study is to evaluate the continued safety and performance of the marketed Evolution® Esophageal Stent System (Partially- and Fully Covered).
This study is an evaluation of the flexible and integrative psychiatric care model (according to § 64b of the German Social Code Book V (SGB V)) (FIT) at the Pfalzklinikum. The central concern of this evaluation is to answer the question whether the FIT model offer advantages over standard care. The orientation of model care is a more cross-sectoral provision of services through more flexible treatment intensities.
