NCT04092101
Prevalence of smoking among individuals with opioid use disorder (OUD) is six-fold that of the general US adult population. The mortality rate of opioid-dependent smokers is four times that of opioid-dependent nonsmokers, and their response to smoking cessation interventions is notoriously poor. A national policy of reducing the nicotine content of cigarettes has the potential to be an effective method of reducing tobacco use prevalence, dependence, and related adverse health outcomes. Controlled trials in the general smoker population have demonstrated that switching smokers to low nicotine content cigarettes results in reductions in cigarettes per day (CPD), dependence and tobacco toxicant exposure, with few adverse consequences. The investigators believe that the impact of reduced nicotine standards on use of combusted cigarettes in this population will be moderated considerably by other tobacco market conditions including (1) availability of alternative sources of non-combusted nicotine, and (2) whether these alternatives are available under conditions that optimize their appeal. The investigators hypothesize the same for other vulnerable populations as well, but achieving significant reductions in use of combusted cigarettes in smokers with OUD seems especially unlikely in the absence of readily available and appealing alternative sources of non-combusted nicotine. The goal of the proposed trial is to experimentally model whether increased availability and appeal of an alternative, non-combusted source of nicotine (e-cigarettes) will enhance the effectiveness of a reduced nicotine standard for cigarettes in smokers with OUD. Additionally, the investigators will test whether allowing participants to personalize the favor of the e-liquid alters any moderating effects their availability may have on tobacco cigarette smoking. Daily smokers who are receiving methadone or buprenorphine treatment will be recruited at University of Vermont and Johns Hopkins University. The investigators will study two research cigarettes referred to here as RC1 and RC2. One of these cigarettes will be a normal nicotine content cigarette and the other will be a reduced nicotine content cigarette. Investigators will study two e-cigarette conditions referred to here as EC1 and EC2. Both e-cigarette conditions will involve the same commercially available devices and same nicotine-containing e-liquid, but in one condition that e-liquid will be available only in tobacco flavor while in the other condition that e-liquid will be available in multiple flavors from which participants can choose based on personal taste preference. Participants will be assigned to one of the following four study conditions: (1) RC1 only; (2) RC2 only; (3) RC2 + EC1; (4) RC2 + EC2. Participants will be asked to use only their assigned study products for 16 weeks. Outcome measures include total CPD, cigarette demand assessed by behavioral economics-based purchase tasks, craving, withdrawal, psychiatric symptoms, breath carbon monoxide (CO), and biomarkers of tobacco toxicant exposure.

NCT00381641
This phase II trial studies how well sunitinib malate works in treating patients with thyroid cancer that did not respond to iodine I 131 (radioactive iodine) and cannot be removed by surgery. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
NCT05726058
The goal of this clinical trial is to investigate the use of an FDA-cleared retinal blood flow imaging instrument called the XyCAM RI and XyCAM FC (Vasoptic Medical, Inc., Columbia, MD) in glaucoma management. The main question it aims to answer are: * Can the investigators use blood flow to discriminate between eyes with early-stage glaucoma and variable-matched controls? * Can the investigators validate that the XyCAM FC simultaneously captures both stereo fundus photography and ocular blood flow monitoring? Participants will be * measured for their blood pressure, heart rate, height, and weight * dilated with tropicamide * imaged using the XyCAM RI, fundus photography, optical coherence tomography, and standard automated perimetry * imaged using the XyCAM RI while inhaling 100% oxygen through a mask
NCT03707158
The Kids FACE FEARS (Kids Formats of Anxiety Care Effectiveness study For Extending the Acceptability and Reach of Services) is a large-scale, streamlined, pragmatic Randomized Controlled Trial (RCT) evaluating Therapist-Led CBT (telehealth, office-based, or hybrid) vs. Guided Online Cognitive-Behavioral Therapy (CBT) for the treatment of elevated child and adolescent anxiety. Families will be recruited from pediatric health centers serving primarily racial/ethnic minority youth in urban, suburban, and semi-rural regions. Services will be offered in English and Spanish. Patient-centered outcomes will be evaluated across a one-year follow-up period. To compare the effectiveness of the two treatment comparators, investigators will analyze the reports of caregivers, youth, and therapists, as well as independent evaluators who are not informed of each child's treatment assignment. Primary outcomes will focus on family-rated anxiety severity and impairment, treatment responder and remission status rated by independent evaluators, family-perceived effectiveness, and treatment satisfaction. Secondary analyses will examine additional outcomes, predictors of varied outcomes across different subgroups of youth, and facilitators and barriers to treatment implementation. Caregivers, patients, providers, and other key stakeholders will be actively engaged throughout all aspects of the research.

NCT05261191
Study CP-MGD020-01 is a phase 1, open-label, dose-escalation, and multi-dose expansion study of MGD020 as a single agent or in combination with MGD014 in persons with HIV-1 (PWH) on antiretroviral therapy (ART). The study is designed to evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity, and pharmacodynamics (PD) of the study drugs. The study consists of 3 parts (Part 1A, Part 1B, and Part 2). The participant's standard of care ART regimen is continued throughout the study period. MGD020 is a bispecific DART® molecule that binds CD3 and gp41 subunit of HIV-1 envelope. MGD014 is a bispecific DART® molecule that binds CD3 and gp120 subunit of HIV-1 envelope. These DART molecules redirect CD3+ T lymphocytes to kill HIV-1-infected CD4+ T cells. Part 1A evaluates groups of participants given a single dose of MGD020. A 2-week safety period is observed prior to escalation to the next dose level. Dose escalation continues until either the maximum tolerated dose (MTD) or maximum administered dose (MAD) is determined. Part 1B begins after the end of Part 1A. Part 1B evaluates groups of participants given a single dose of the MGD020 MTD or MAD from Part 1A and a fixed dose of of MGD014. The first group will be treated with a single dose of MGD020, at a dose determined to be one dose lower than the single-agent MTD/MAD from Part 1A, and a single 300 mcg/kg dose of MGD014. Dose escalation proceeds until either the MTD or MAD is determined. Part 2 begins after the end of Part 1B. Part 2 is a multi-dose expansion group. Each participant will receive the MTD or MAD of MGD020 from Part 1B and a fixed dose of MGD014 from Part 1B, administered every 2 weeks (Q2W) for 3 combination doses over 4 weeks. Up to 6 participants may be enrolled in Part 2.
NCT05825898
Tricuspid regurgitation (TR) is a public health problem: moderate / severe TR are common, especially in ageing populations, and affect 4% of the population \>75 years old, totaling approximately 1.6 million in the US and 3 million in Europe. TR is associated with an increased risk of mortality and morbidity. Contrasting with TR prevalence and the magnitude of the problem, the vast majority of patients are medically treated with diuretics to relieve their symptoms and a curative surgical treatment for isolated severe TR is seldom performed. Reluctance to perform an ITVS can be explained in the one hand by the limited evidence that TR correction improves outcomes and on the other hand, ITVS is associated to high observed in-hospital mortality rates (≈ 10% remarkably consistent in most series across the literature). Severity of the clinical presentation is the main predictor of outcome after surgery. The TRI-SCORE, is a dedicated, simple and accurate risk score model to predict in-hospital mortality after ITVS that could guide the clinical decision-making process at the individual level. Excellent outcomes can be achieved when patients present with low TRI-SCORE. These results suggest adopting a more pro-active approach for TV interventions, and to intervene earlier in the course of the disease in patients with severe isolated TR, irrespective of TR mechanism / etiology, before the occurrence of advanced / irreversible consequences such as severe RV dilatation / dysfunction, renal and liver failure, and intractable heart failure. Recently transcatheter tricuspid valve interventions (TTVI) have emerged recently as a less invasive option to surgery to cure patients with TR. What is the best treatment between medical, surgical or transcatheter therapy to consider and the best timing for each patient are not clearly defined. The aim of the study is to compare outcome of patients with significant functional TR according to medical, transcatheter or surgical treatment after matching per TRISCORE.

NCT05576350
Ecological momentary interventions (EMI), which use phones to deliver messages to reduce alcohol use and related risk behaviors during or prior to drinking events, can help to address triggers in real-time. GPS tracking can determine when individuals visit places they have previously reported drinking or triggers to drink and then EMI messages can be delivered upon arrival to prevent risky alcohol use. A mobile app has been developed that uses GPS tracking to determine when individuals visit "risky" places and then delivers a survey asking what behaviors they engaged in while at the location. The goal of the proposed study is to use this app to enhance the Tracking and Reducing Alcohol Consumption (TRAC) intervention by delivering messages that encourage participants to employ strategies discussed during TRAC sessions when arriving at risky places. When they leave these places, they will complete a survey and breathalyzer reading in order to collect event-level self-report and biological data on alcohol use and HIV risk. If their breathalyzer result indicates alcohol use, they will receive harm reduction messaging. It is expected that combining TRAC with EMI ("TRAC-ER") will increase effectiveness by reinforcing topics discussed during these sessions, providing in-the-moment messaging to address triggers, and collecting real-time alcohol use data.
