There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The investigators hypothesize that inhibition of angiogenesis and PD-1 will be more effective than inhibition of PD-1 alone. The first step in pursuing proof of this hypothesis is to establish the safety and feasibility of combining ramucirumab with pembrolizumab, therefore the first part of this protocol is a de-escalation phase I trial of the combination of ramucirumab + pembrolizumab. The key objective of the phase I trial is to establish the safety and the recommended phase 2 dose (RP2D) of ramucirumab for this novel combination regimen in patients with recurrent/metastatic head and neck squamous cell carcinoma (RM-HNSCC). The second step in pursuing proof of this hypothesis is to establish the efficacy of ramucirumab (using the RP2D) with pembrolizumab. The second part of this protocol is a single arm phase II trial combining ramucirumab + pembrolizumab. The primary objective of the phase II trial is to determine the tumor response rates (complete response (CR) and partial response (PR)) of the treatment combination given as first line therapy in patients with RM-HNSCC.
This two-part study seeks to improve symptoms such as pain and sleep problems after concussion, or mild traumatic brain injury (mTBI). Study I evaluates symptoms of mTBI through a series of 10 office sessions in which musical tones are echoed, or mirrored back in real time, to reflect one's own brain activity. Those who take part in the study will be randomly assigned to receive either tones that are based on their brain activity/brainwaves, or random tones. Study II evaluates symptoms of mTBI through either 10 office sessions of the same acoustic stimulation linked to brain activity/brainwaves as Study I compared to 5 office sessions of acoustic stimulation plus intermittent very low level electrical stimulation of the scalp linked to brain activity.
The purpose of this study is to train Church Leaders and other community members in Mental Health First Aid (MHFA), which is an evidence-based public mental health education program. MHFA has been found to improve people's recognition of emotional and mental health challenges and to increase people's confidence in providing help to others. Information about MHFA can be accessed at http://www.mentalhealthfirstaid.org. MHFA consists an 8-hour training program in which participants will be provided a manual, learn the signs and symptoms of common mental health problems, and learn a 5-step action plan to help someone in an emotional crisis. Participants ware recruited from faith-based organizations (i.e., churches), health care organizations (i.e., hospitals), and other community based organizations. There will be no treatment directly provided as part of this study.
The purpose of this study is to understand the reliability of [18F]-FTC-146 brain uptake in healthy controls.
In this study investigators propose to address the following hypotheses: 1) Reduction in dietary sodium will decrease inflammation in patients with rheumatoid arthritis (RA). 2) Reduction in dietary sodium will decrease blood pressure in patients with RA. 3) Reduction in dietary sodium will decrease tissue sodium in patients with RA.
This study will compare the effectiveness of two self-management support interventions-Community Health Workers (CHW) and mobile health (mHealth)-versus enhanced usual care to improve health-related quality of life and acute care use for transitioning youth with sickle cell disease (SCD), and identify and quantify mediators and moderators of intervention treatment effects.
The goal of this crossover trial is to determine whether the study drug dehydroepiandrosterone (DHEA) improves right ventricular longitudinal strain measured by cardiac magnetic resonance imaging at 18 weeks compared to placebo and to assess side effects and safety in pulmonary arterial hypertension.
The purpose of this study is to examine how the timing of eating changes how the body makes and uses energy (metabolism). This study will also examine if metabolism changes with age.
Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting millions of people in the US and around the world. Over the last 20 years, catheter based AF ablation has been widely adopted offering improved symptom control for many patients worldwide. However, long-term success rates remain suboptimal. Prior work indicates that distal connections between coronary sinus musculature and the left atrium exist and provide a substrate for single or multiple reentry beats as a trigger for atrial fibrillation. In this trial, the investigators will examine the efficacy of elimination of distal connection(s) between coronary sinus and left atrial musculature for suppression of recurrent atrial arrhythmias.
The objective of this study is to evaluate the safety, pharmacokinetics and tolerability of multiple doses of upadacitinib in pediatric participants with severe atopic dermatitis and to evaluate palatability of upadacitinib oral solution in pediatric participants.
