NCT ID: NCT03367780 Recruiting - HNSCC Clinical Trials

Dose‐Effect Relation of Salivary Gland Irradiation

Start date: November 21, 2017
Phase: N/A
Study type: Observational

Optimization of radiotherapy to reduce xerostomia is difficult, because many gland locations cannot be seen with current imaging modalities and biological dose‐effect are currently insufficiently understood. PSMA PET is a new diagnostic instrument which can visualize the presence of vital acinar cells in salivary gland locations throughout the head and neck, with a sensitive and quantitative signal. A reduction of PSMA accumulation in salivary glands is thought to correlate with loss of vital acinar cells. The PET images can be correlated with radiotherapy dose distributions in gland‐based or voxel‐based evaluations. This makes PSMA PET a suitable instrument to derive the radiobiological dose‐effect relations that are required to develop better and gland‐specific dose constraints for radiotherapy. The results of this study can contribute to lower toxicity and better quality of life in patients treated with high‐dose radiotherapy in the head and neck.

NCT ID: NCT03366090 Recruiting - Ulcerative Colitis Clinical Trials

Immunological Profiles in Inflammatory Bowel Disease

Start date: October 1, 2017
Phase: N/A
Study type: Observational

Inflammatory Bowel Diseases (IBD) is a heterogeneous group of diseases regarding clinical presentation, disease course and treatment response. Pathogenesis is complex and multifactorial, based on interactions between genetic and environmental factors, gut microbiota and the immune system, leading to intestinal inflammation. As the immune reaction itself causes the intestinal damage, differences in components of this immune mediated inflammatory reaction between IBD patients might explain the heterogeneity in response to different therapy strategies. Identifying immune components that are associated to disease activity and prognosis would enable a more personalized treatment.

NCT ID: NCT03364894 Recruiting - Parkinson Disease Clinical Trials

The Personalized Parkinson Project (PPP)

Start date: October 1, 2017
Phase: N/A
Study type: Observational

Background Our understanding of PD has stagnated, partly due to the limited patient diversity and brief followup captured in most study cohorts. Additionally, potentially valuable biomarkers derived from different types of measurements are rarely analyzed in an integrated fashion. Objective This study aims to create a longitudinal dataset of clinical, molecular, imaging, and continuous wearable sensor-based data from a representative Parkinson's disease (PD) cohort. Data will be made available to researchers worldwide to accelerate the discovery of novel etiological insights, development of new therapeutic approaches, and personalized disease management. For this purpose, an extensible norm for sharing research data will be developed, meeting the latest data privacy and security standards. Methods Supported by a multinational, public-private partnership, a prospective cohort study was designed to include 650 representative PD patients (disease duration <5 years). Comprehensive follow-up for at least 2 years includes: (1) annual assessment at the study center for acquisition of detailed clinimetric data, magnetic resonance imaging, and biospecimens (plasma, serum, cerebrospinal fluid (CSF), stool) and (2) collection of data from the home environment, using self-assessments and an advanced wrist-worn wearable device to continuously measure biological and environmental signals. Collection, storage, and sharing of these research data will be facilitated by a new method to protect privacy and enhance security using polymorphic encryption and pseudonymization (PEP), a methodology that combines advanced encryption with distributed pseudonymization and data access management. Conclusion This study is unique, as it includes a cohort of unbiased subjects with recently diagnosed PD, creating an unprecedented dataset that combines longitudinally collected clinical, molecular, imaging, and data from wearable sensors using state of the art technology. The single-center study design minimizes measurement variability. Finally, the innovative methodology for data privacy and protection might serve as a new international standard for sharing research data.

NCT ID: NCT03361098 Recruiting - Obesity Clinical Trials

DECREASE: Dapagliflozin Plus Exenatide on Central REgulation of Appetite in diabeteS typE 2

Start date: September 18, 2017
Phase: Phase 4
Study type: Interventional

This is a 16 week, phase 4, randomized and placebo controlled trial, investigating the separate and combined effects of Sodium Glucose coTransporter 2 (SGLT2) inhibition with dapagliflozin and Glucagon Like peptide-1 (GLP-1) receptor agonism with exenatide on food intake, body weight and the neural activity in the central satiety and reward circuits in response to food-related stimuli by blood oxygen level-dependent (BOLD) fMRI in obese type 2 diabetes patients. The investigators hypothesize that treatment with SGLT2 inhibitors is associated with alterations in central reward and satiety circuits in response to food related stimuli, leading to increased appetite and food intake. In addition, the investigators hypothesize that adding a GLP-1 receptor agonist to the treatment with an SGLT2 inhibitor may increase weight loss and prevent the increased food intake during treatment with SGLT2 inhibitors due to effects on neuronal activity of central satiety and reward circuits in response to food-related stimuli in obese patients with T2DM.

NCT ID: NCT03360851 Recruiting - Clinical trials for Community-acquired Pneumonia

DiagNostic Study of Low-dose CT and multipleX PCR on Antibiotic Treatment and Outcome of Community-Acquired Pneumonia

Start date: November 27, 2017
Phase: N/A
Study type: Interventional

Rationale: Uncertainty in the clinical and etiological diagnosis of community-acquired pneumonia (CAP) often leads to incorrect treatment and unnecessary use of broad-spectrum antibiotics. Establishing the clinical diagnosis of CAP is hampered by the suboptimal sensitivity of chest radiograph to detect pulmonary infiltrates (~70%). Establishing the etiological diagnosis is also hampered, mainly because of the inevitable diagnostic delays and low sensitivity of routine microbiological tests. There are currently no recommendations for low-dose chest computed tomography (low-dose CT) or viral and bacterial point-of-care multiplex polymerase chain reaction (PoC-PCR) in the diagnostic work-up of CAP patients, because the data supporting such an approach are lacking. Objective: The aim of this study is to determine the added value of low-dose CT and PoC-PCR in the diagnostic workup of patients with CAP hospitalised to non-intensive care unit (ICU) wards in minimizing selective antibiotic pressure while maintaining patient safety. Study design: Cluster-randomised controlled trial with historical control period. Study population: Adult patients (>=18 years old) with a clinical diagnosis of CAP requiring hospitalisation to a non-ICU ward. Intervention: Intervention arm 1: availability of PoC-PCR during the ER visit; intervention arm 2: performing low-dose CT from the ER or at least within 24 hours; control arm: standard care. Main study parameters/endpoints: The primary effectiveness outcome is days of therapy of broad-spectrum antibiotics. The primary safety outcome, on which the sample size is calculated, is 90-day all-cause mortality. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no risks associated with performing the PoC-PCR and the radiation of the low-dose CT is of negligible risk. Nasopharyngeal swab collection causes a temporary unpleasant sensation. The low-dose CT can reveal unexpected findings which may require additional diagnostic procedures, for which the treating physician will use state-of-the-art guidelines. Treatment recommendations to de-escalate or stop antibiotic treatment may be beneficial for the individual patient by minimising exposure to antibiotics and improve targeted use of antibiotics. Final decisions are always made by the treating physician taking into account all clinical information.

MoA aIL-17
Start date: March 2014
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine the mechanism of action on target tissue level of anti Interleukine-17 (anti-IL-17) an therapy in peripheral spondyloarthritis.
