NCT02374021
In a randomized controlled clinical trial, investigators will compare the effects on \[18F\]-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) from two treatment regimens in rheumatoid arthritis (RA) patients deemed methotrexate inadequate responders (MTX-IRs). Two common RA treatments will be compared: triple therapy (sulfasalazine, methotrexate, and hydroxychloroquine) versus tumor necrosis factor (TNF) inhibitor (etanercept or adalimumab, plus background methotrexate for all subjects and hydroxychloroquine for subjects who were taking this at screening).
NCT03579641
The goal of the PREEMPT-HF study is to collect device and clinical event data to evaluate extended applications of the HeartLogic Heart Failure Diagnostic (HeartLogic) in a broad spectrum of heart failure patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy defibrillator. There are no primary safety and/or efficacy endpoints for this study. Heart failure is a complex clinical syndrome with high morbidity, mortality, and economic burden. Chronic Heart Failure is persistent, gradually progressive, and punctuated by episodes of acute worsening leading to hospitalizations. Therefore, there remains an unmet clinical need to slow the progression of Heart Failure and prevent hospitalizations. HeartLogic, available in Boston Scientific cardiac resynchronization therapy devices and defibrillators, combines novel sensor parameters such as heart sounds and respiration with other measurements like thoracic impedance, heart rate, and activity into a HeartLogic Index for the early detection of worsening Heart Failure. However, there is limited data on the association of HeartLogic with the risk of Hear Failure readmissions and tachyarrhythmias, or for phenotyping the broad spectrum of Heart Failure patients.
NCT03320512

NCT01531374
The purpose of the study is to evaluate the safety and efficacy of the Medtronic CoreValve® System in the treatment of symptomatic severe aortic stenosis in subjects who have a predicted very high risk and high risk for aortic valve surgery.
NCT02028338
To assess the safety of dapivirine (25 mg) administered via a silicone vaginal ring in HIV-uninfected adolescent females, when inserted once every 4 weeks during 24-week of study product use.
NCT04465201
To demonstrate that the Impella® Hemodynamic Platform (the "Study Device") is safe, and measurements obtained are as good as currently used methods. These measurements include how much pressure the heart is generating and how much blood your heart is pumping during the PCI.
NCT01767194
This randomized phase II trial studies how well irinotecan hydrochloride and temozolomide with temsirolimus or dinutuximab work in treating younger patients with neuroblastoma that has returned or does not respond to treatment. Drugs used in chemotherapy, such as irinotecan hydrochloride and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as dinutuximab, may find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving irinotecan hydrochloride and temozolomide together with temsirolimus or dinutuximab is more effective in treating neuroblastoma.
NCT00530868
This purpose of this trial is to show that the combination of Avastin and hormone therapy should be more effective than hormone therapy alone for the treatment of breast cancer.
NCT00145600
With the success of current chemotherapy for Hodgkin's disease, the goal of this protocol is to maintain the currently successful cure rate and reduce treatment related side effects and long term toxicity. The main purpose of this study is to estimate the event free survival of patients treated with risk-adapted therapy compared to historical controls.
NCT02562716
This randomized phase II trial studies how well fluorouracil, irinotecan hydrochloride, and oxaliplatin (combination chemotherapy) works and compares to gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation before surgery in treating patients with pancreatic cancer that can be removed by surgery. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, oxaliplatin, gemcitabine hydrochloride, and paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known whether combination chemotherapy is more effective than gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation before surgery in treating pancreatic cancer.
NCT04164563
Evaluating impact of use of Even-Up shoe wear device for patients treated in CAM boot walker for an ankle fracture. Randomized controlled trial, randomizing patients into control group with boot treatment only versus boot treatment with Even-Up device on contralateral extremity.
NCT03406975
Endoscopic Sleeve Gastroplasty (ESG) is an endoscopic minimally invasive weight loss procedure where a commercially available, FDA approved, full-thickness endoscopic suturing device (Overstitch; Apollo Endosurgery, Austin, TX) is used to reduce the stomach volume by 80% through the creation of a restrictive endoscopic sleeve. This is accomplished by a series of endoscopically placed full-thickness sutures through the gastric wall, extending from the antrum to the gastroesophageal junction. Up to 200 participants at 9 locations in the United States will participate in this study. The ESG procedure has been performed clinically since 2013 in the United States. The investigators are completing this study to compare how effective the ESG is for achieving long-term weight loss when compared to lifestyle modification only, as well as to evaluate the long-term safety and durability of the procedure and its impact on quality of life. Results of this research may help support having this procedure covered by health insurance plans for future patients.
NCT03665441
This is an open-label, multicenter, randomized, Phase 3 study in patients with ductal adenocarcinoma of the pancreas who have failed only one prior line of systemic anti-cancer therapy for advanced pancreatic cancer and have measurable disease.
NCT05587634
Participation in physical activity (PA) confers clear physical and psychosocial benefits. Yet, many adolescents with physical disabilities such as cerebral palsy and spina bifida do not engage in regular PA, putting them at increased risk for the detrimental impact of sedentary lifestyles such as high rates of obesity/overweight - adverse health trends that continue into adulthood. To address this PA gap, a feasibility pilot randomized controlled trial is proposed evaluating the utility of a peer health coach intervention to promote PA participation and to improve outcomes related to self-autonomy, self-efficacy, and quality of life in adolescents with physical disabilities. Peer health coaches will themselves be young adults with disabilities, trained in concepts of motivational interviewing and self-determination theory, enabling them to meet participants "where they are at" in their understanding of PA and readiness to change PA behaviors. This study will be novel given that: 1) for the first time, an adult peer health coaching model targeting PA will be adapted to the needs of adolescents with disabilities, 2) the study will employ text messaging and other social media platforms that are highly relevant to an adolescent population, and 3) the study will assess PA participation with use of ActiGraph activity trackers, designed to monitor both duration and intensity of PA in individuals with mobility impairment. The results of this study will be used to inform the design of a future, definitive RCT evaluating the efficacy of a peer health coaching intervention to create meaningful change in physical and psychosocial outcomes. By empowering adolescents with disabilities to take control of their own physical and psychosocial health, this work has the potential to impact the well-being and quality of life of participants for many years to come.
