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).
NCT03320512
P3 (Prepared, Protected, emPowered) is an interactive smartphone app for HIV-uninfected YMSM and YTW that utilizes social networking and game-based mechanics as well as a comprehensive understanding of what constitutes "best practices" in app development to improve PrEP adherence and persistence in PrEP care.
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.
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.
NCT04241796
PATHFINDER is a prospective, multi-center study in which approximately 6,200 participants will be enrolled. An investigational multi-cancer early detection test, developed by GRAIL, will be ordered by and results returned to a study investigator. In cases with a "signal detected" test result (with a predicted or indeterminate tissue of origin (TOO)), the diagnostic work-up will not be dictated by the protocol, but will instead be coordinated by the ordering and treating medical team at the enrolling sites based on the participant's clinical condition, recommendations by each institution's clinical practices, and in consultation with the study investigator and interdisciplinary care team, as necessary. Additionally, proposed clinical care pathways, developed based on a review of guidelines from the National Comprehensive Cancer Network (NCCN), American College of Radiology (ACR) and other professional organizations, should be referenced by the medical team to determine the diagnostic work-up. The number and types of diagnostic procedures required to achieve diagnostic resolution will be assessed. Performance of multi-cancer early detection test will be evaluated. Additionally, participant-reported outcomes will be collected at several time points to assess participants' perceptions about the multi-cancer early detection test. Participants will be followed for approximately 12 months from the time of enrollment. Cancer status will also be assessed at the 12 month time point.
NCT01240902
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 high risk for aortic valve surgery and/or very high risk for aortic valve surgery.
NCT04465201

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.
NCT02133924
This research trial is designed to study the safety and effectiveness of combining the study drug, Natalizumab (Tysabri®) with the standard treatment, the use of steroids, as a new treatment for acute graft versus host disease (acute GVHD). GVHD is the most common serious complication, after bone marrow transplant. GVHD occurs when the donor cells (the graft), treat the recipient's body as "foreign" and attack the cells in the recipient's body. During this immune system response, donor cells damage body tissues, such as the skin, liver, stomach, and/or intestines. Acute GVHD can be severe and if severe, potentially fatal to the transplant recipient. Acute GVHD usually happens within the first several months after transplant. The goal of this research is to develop a safer and more effective treatment for acute GVHD, and particularly for acute GVHD that affects the gastrointestinal (or GI) tract, with the ultimate goal being safer and more effective transplant therapies for blood cancers such as leukemia, lymphoma, and multiple myeloma.
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.
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.

NCT05020730
Study PTM-001-01 is a 12-week, randomized, placebo controlled, double blind study with a 12 week open-label extension to examine the immunomodulatory activity of PTM-001 in participants with Hidradenitis Suppurativa (HS). Participants will be randomized to receive PTM-001 (400 mg) or matching placebo every day for 12 weeks after which all participants will receive open-label PTM-001 400 mg daily for an additional 12 weeks. Randomization will be stratified by Hurley Stage.
NCT04130698
The study has two phases. In Phase 1, the investigators will revise and pilot the distress tolerance (DT) protocol that was originally developed and piloted in a previous study (2P20 GM103430, Spas, PI). Despite the 4-week post-intervention treatment outcomes demonstrating the DT protocol's association with smoking cessation and weight loss, several revisions to the DT protocol are important to improve the intervention. First, the investigators will include the overweight/obese smokers' group-level feedback that the investigators collected during the 7-week intervention and at the 4-week post-intervention individual interviews to tailor the DT protocol to meet the unique needs of smokers with excess weight. Subjects from the previous study revealed factors that led to current and/or previous successful smoking cessation and weight loss efforts, barriers to sustaining current and/or previous successful smoking cessation and weight loss efforts, and general feedback about DT intervention for both health risks. The investigators believe revising the DT protocol to include overweight/obese smokers' unique experience with the novel intervention and their acumen about these key factors will improve the intervention and its generalizability to smokers with excess weight. Additional revisions are described elsewhere. After the investigators pilot the revised DT protocol, the investigators will revise the active health control protocol comprised of standard treatment for smoking cessation and weight loss to ensure both protocols equate for intervention contact time. Although both protocols will have some similar content, to avoid any threats to internal validity, no DT-specific material will be included in the control. In Phase 2, the investigators will conduct a two-armed, preliminary randomized controlled trial (RCT) to compare the revised DT protocol's efficacy to the active health control protocol.
