NCT02656693
The goal of this project is to adapt an evidence-based online weight management program and integrate it with population management support from primary care practices. Investigators then will conduct a three-arm, cluster-randomized trial to compare the effectiveness of 1) the combined intervention (online weight management program plus population management support) with 2) the stand-alone online weight management program and with 3) usual care, among overweight and obese primary care patients with type 2 diabetes or hypertension. The specific aims are: 1. a. To adapt an online weight management program and integrate it with population management support, incorporating input from patients, primary care clinicians, and other stakeholders; afterward, investigators will acquire feedback on the positive and negative aspects of the intervention. b. To compare the effectiveness of the combined intervention (online weight management program plus population management support) with the stand-alone online program and with usual care. Hypothesis 1: The combined intervention will lead to greater weight loss at 12 months compared with the stand-alone online program and with usual care. 2. To identify mediators of the combined intervention and the stand-alone online program. Hypothesis 2: The effects of the combined intervention and the stand-alone online program on weight loss will be mediated by patients' level of engagement, changes in self-efficacy, and changes in diet and physical activity. 3. To explore whether the effectiveness of the combined intervention and the stand-alone weight management program varies by patient characteristics. Hypothesis 3: The interventions will be more effective among patients who are younger, white, and higher socioeconomic status, although the population management strategy may help to reduce these differences.
NCT03223246
Acetaminophen and ibuprofen are two of the most commonly used medication products among children \<12 years old, and these medications are frequently prescribed for patients leaving the emergency department (ED), but previous studies have shown that parents often leave the ED unsure of how to safely dose these medications at home. This study will be a randomized controlled trial of a brief medication safety intervention, and examining parental knowledge and implementation of appropriate weight-based dosing.
NCT00181662
This study looks to describe the pharmacokinetics of curcumin delivered as a single oral dose in healthy female volunteers. The impact of piperine and silybin on the pharmacokinetics of curcumin is also studied.
NCT02802514
The drug effects will be studied after a single dose of 50 milligram (mg) albiglutide and a single dose of 10 microgram exenatide, to gain insight into the central mechanisms of nausea associated with Glucagon-like peptide-1 receptor (GLP-1R) agonists. This study will explore the potential differences at the expected time of maximum concentration (Cmax) between a long-acting (albiglutide) and short-acting (exenatide) GLP-1R agonist in brain activation of healthy volunteers assessed by magnetic resonance imaging (MRI). This is a phase IV, 2-part, 2-period crossover (session), single dose, randomized, single blind (blinded to both the subject and the imaging evaluators analysing the MRI data), placebo- and active-controlled study in adult healthy volunteers who are susceptible to motion sickness. Part A and Part B are the same in design, both consisting of a screening stage, a dosing/assessment stage, and a follow-up visit. Data from Part A will inform progression, methods, and analysis plan for Part B. Each sequence includes three scanning visits: albiglutide plus scan, exenatide plus scan and an off-therapy -natural history scan with a 6-9 week washout period between the dosing scans. A total of 24 to 28 subjects will be randomized in the study (Part A and Part B). The cross over design is divided into 2 sessions and schedule is as follow, on Day 1 (either Session 1 (S1) or Session 2 (S2) per, if randomized) subject will under go an off-therapy MRI scan, on Day 5 subject will receive a single dose of 50 mg albiglutide or albiglutide placebo, and Day 8 subject will receive a single dose of 10 microgram exenatide or saline placebo followed by a post-dose MRI scan. At each session subject will receive only one active drug (albiglutide or exenatide).
NCT01355497
The purpose of this study is to determine if the investigational drug GTx-024 can help patients with non small cell lung cancer increase physical function and maintain or gain muscle.
NCT02484690
This multiple-center, multiple-dose and regimen, randomized, double-masked active comparator-controlled, double-masked, five parallel group, 36-week study will evaluate the efficacy, safety, tolerability, and pharmacokinetics of faricimab (RO6867461) in participants with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The study was designed to allow the evaluation of RO6867461 in a treatment-naive population (comparison of Arms A, B, C, and D) and an anti-VEGF-incomplete responder population that met a predefined criterion at Week 12 (comparison between Arms A and E). Only one eye per participant was chosen as the study eye.
NCT03564210
This study will prospectively examine the effect of screen time on recovery from concussion. Patients 12 to 25 years of age presenting to the ED with a concussion will be randomized to allow for screen time as tolerated or to abstain from screen time for the first 48 hours of recovery. The amount of screen time use and duration of concussive symptoms will be assessed through daily surveys and a daily post-concussive symptom score (PCSS).
NCT04420858
The investigators propose a randomized controlled trial to assess baseline maternal knowledge of and attitudes toward commercial prenatal genetic testing laboratories' genetic privacy practices, and to determine whether a brief educational intervention alters these attitudes.
NCT04615351
A Pilot of Metformin Postpartum
NCT02610140
The main purpose of the 15743 study is to assess efficacy and safety of anetumab ravtansine versus vinorelbine in progression free survival in patients with stage IV mesothelin overexpressing malignant pleural mesothelioma (MPM). 210 eligible patients will be randomized to receive either anetumab ravtansine every three weeks or weekly vinorelbine. Treatment will continue until centrally confirmed disease progression or until another criterion is met for withdrawal from the study. Patients will enter follow up phase to capture safety and endpoint data as required. Efficacy will be measured by evaluating progression free survival from randomization. Radiological tumor assessments will be performed at defined time points until the patient's disease progresses. Blood samples will be collected for safety, pharmacokinetic and biomarker analysis. Archival or fresh biopsy tissue may also be collected for central pathology review and biomarkers.

NCT04235361
A mobile suitcase laboratory for EBOV point-of-care (POC) detection at Ebola treatment centers was successfully implemented in Guinea during the large Ebola virus disease (EVD) outbreak in West-Africa 2014-2015. It was shown that isothermal amplification (Recombinase Polymerase Amplification (RPA)) could be efficiently used to test suspect EVD cases and local teams were trained in and successfully deployed with this fast method. In the frame of this project we want to train teams in DRC and expand RPA testing capacity to the differentials recommended by the WHO. Existing RPA assays for all parameters will be included into a multistrip for simultaneous use. This will be integrated with a simple biosafe extraction method. Implementing this approach and testing in the ongoing EVD outbreak will provide teams in DRC with response capacity for future EVD outbreaks.

NCT02023970
Cardiac valve disorders are widely spread in the general population and represents the third most frequent cardiovascular illness after coronary disease and arterial hypertension. In this context, aortic valve stenosis (the central pathology in this project) is the most common form of valve disease. Cardiac valve replacement is in the vast majority of cases the first line therapy for degenerative heart-valve diseases. These are represented by mechanical and bioprosthetic valve (BHV). In the vast majority of cases, BHV are derived from animals and from a biological standpoint are classified as xenografts. BHV are severely penalised by a premature structural damage, with ultimate valve failure occurring around 10 years after surgery in 5 to 30% of cases, depending on the type of BHV used. Several factors \[including dyslipidaemia, gender, valve position\] may contribute to the ultimate failure of the BHV and there has been increasing evidence recently of a substantial immune reaction elicited by the implanted BHV. This immune response is still poorly understood. It may lead to adverse immune reactions and this will be thoroughly investigated by the TRANSLINK team. In this light, the TRANSLINK project aims to provide the necessary data to demonstrate beyond any reasonable doubt the central role of the anti-BHV immune response in the premature failure of BHV and to provide efficient strategies to enable safe implantation of BHV valves in currently unsuitable candidates
