There are about 25348 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.
This observational study investigates whether the daily measured trend of cardiac output as evaluated by indirect calorimetry correlates with the same evaluated by transthoracic echocardiography.
The clinical trial is intended to evaluate the efficacy, safety and economic benefit of coronary lithotripsy compared to other additional procedures (cutting or super high pressure balloon angioplasty, ablative procedures) in lesion preparation and interventional treatment of severely calcified coronary stenoses.
Patients with head and neck cancer requiring definitive or adjuvant radio(chemo)therapy can take part in the study. The aim is to record the nutritional status and diet of the patients during the trial and regularly at a period of 8 weeks after irradiation and to reduce the rate of weight loss and malnutrition.
Hormonal transition periods during the menstrual cycle may predispose women to mental disorders. Hormonal fluctuations provide specific neuroendocrine conditions that modulate brain structure and function and these actions affect cognitive and emotional behaviors and affect energy and mood homeostasis. It is thought that these changes are driven by altered dopamine transmission. Here, we aim to examine (1) how sex hormones and dopamine are linked and also (2) how hormonal changes affect motivation, mood, and energy homeostasis. To this end, dopamine intervention will be tested on effort-based decision-making and motivational circuits in three hormonal stages (i.e., women in early-follicular phase (EF), women in mid-luteal phase (ML), and men). Additionally, we are testing the effects of hormonal status on metabolic indices and its effects on mood fluctuations in a period of a month. The investigator hypothesizes that women in EF cycle phase (1) have naturally less dopamine and show less effort, and (2) they show greater improvement in effort-based decision-making after Levodopa administration. We have exploratory outcomes about (3) sex differences in reward-learning with and without Levodopa administration and explore if these differences correlate with elevated female sex hormone levels. Moreover, it is hypothesized that (4) hormonal fluctuations affect energy homeostasis, thus women in their EF cycle phase have higher energy expenditure and (5) they report more negative mood than in their mid-luteal (ML) cycle phase.
The purpose of this study is to evaluate efficacy and safety of Dato-DXd in combination with rilvegostomig or rilvegostomig monotherapy compared with pembrolizumab monotherapy as a first line therapy in participants with locally advanced or metastatic non-squamous NSCLC with high PD-L1 expression (TC ≥ 50%) and without actionable genomic alterations.
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
In this prospective, multi-center cohort study, the tolerability and quality of life during ultrahypofractionated radiotherapy (RT) of early stage prostate cancer is surveyed at several institutions in Germany. Radiotherapy is delivered with by an online-adaptive RT device (Varian Ethos), which is able to correct daily variations in anatomy and to adjust the irradiation plan accordingly. A digital patient questionnaire is used to asses quality of life longitudinally. Quality of life (QoL) and toxicity profiles will be correlated with planning parameters and compared to retrospective cohorts of patients who underwent normofractionated RT or moderately hypofractionated RT, respectively.
The study aims to investigate the effect of anti-estrogenic therapy in breast cancer patients on neural reward processing, psychosexual health, and quality of life, in reproductive vs. menopausal women. The investigators are directly comparing four groups 1) premenopausal women diagnosed with breast cancer receiving anti-estrogenic therapy, 2) postmenopausal women diagnosed with breast cancer with and without previous hormonal replacement therapy, receiving anti-estrogenic therapy, 3) premenopausal healthy women, and 4) postmenopausal healthy women. Furthermore, via assessment and integration of various data including subjective/self-report data via questionnaires and a standardized interview, physiological/endocrine (via blood sample), psychological and neural data (including anatomical scans, Diffusion tensor imaging (DTI), resting state, and a reward processing paradigm), this project will shed light on the connection between the brain, anti-estrogenic therapy, and psychosexual health.
The goal of this observational cohort study is to compare patients with very low red blood counts who receive different therapy. Its main question[s] it aims to answer are: - Which group of patients dies more frequent: Patients who receive patient blood management only, patients who receive patient blood management and transfusions or patients who receive only transfusions? - Among these groups: which group of patients has more complications during hospital stay? Patients will either receive patient blood management, which is the management of anemia, bleeding and coagulation problems, will receive transfusions, that is, blood from other people, or a mix of both.
The 3TR-ICS COPD study is an international, multicentre, randomized, parallel, controlled study that will recruit clinically stable former smokers COPD patients (with no exacerbations in the previous 8 weeks) on treatment with dual long-acting bronchodilators (LABA+LAMA), minimum 8 weeks of usage, not receiving ICS (either naïve or > 3 months since last usage). The overall objective of this clinical trial is to identify the molecular signatures associated with the molecular response to ICS treatment in patients with COPD stratified by the levels of circulating eosinophils, and the potential influence of the pulmonary microbiome
