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.
This study will determine whether vitamin D3 prevents severe asthma attacks in children who have a serum vitamin D (25(OH)D) level <30 ng/ml and who are being treated with inhaled corticosteroids for asthma. Half the participants will receive vitamin D3 at a dose of 4,000 IU/day, and the other half will receive placebo.
This study is designed to evaluate the effectiveness of a novel amblyopia treatment - Intermittent occlusion therapy (IO-therapy) glasses (AmblyzTM) in treating severe amblyopia. Children ages 3 to 8 years with severe amblyopia (visual acuity of 20/100 to 20/400 in the amblyopic eye) will be enrolled and randomized into two groups: 1) standard 6-hour patching group or 2) 12-hour IO-therapy glasses group. The study also observe the effectiveness of IO-therapy glasses on two types of difficult amblyopia: deprivation amblyopia associated with congenital or developmental cataract, and myopic anisometropic amblyopia.
The purpose of this study is to evaluate the efficacy, safety and tolerability of PF-06649751 in Parkinson's disease patients who experience motor-fluctuations.
The purpose of the study is to evaluate the efficacy, tolerability, safety and pharmacokinetics of Oxymorphone HCl as an analgesic for acute moderate to severe post-operative pain in pediatric subjects.
Open label, nonrandomized, dose-escalation trial of MVT-2163 and MVT-5873 used in performing PET scans. The study is designed to determine the best time and dose of these agents that result in the best PET image of a tumor. Subjects will be seen on days 1, 2, 4, and 7 for imaging and a clinical assessment. The last study visit is on day 28.
This study employs a modified continual reassessment method (mCRM) design to estimate the maximum tolerated dose (MTD) of PF-05230907, defined as a target toxicity rate of 15% based on treatment emergent thromboembolic and/or ischemic events (TIEs). The mCRM design utilizes Bayesian methodology to continuously learn the dose-toxicity relationship, which is characterized by a parametric model. Subjects with a diagnosis of ICH (determined by computed tomography) will be enrolled in cohorts of 3. The total length of time planned for study participation is approximately 3 months; 6.0 hours for screening, a single dose administration with a 4-day minimum hospital confinement period and follow-up visits through Day 91. Severity of adverse events (AEs) and serious adverse events (SAEs) will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. All subjects who receive PF-05230907 are evaluable for TIEs. The determination of MTD using mCRM modeling will be based on TIEs which occur through 7 days post-dose (Day 8).
This study will investigate (a) neural and immune mechanisms underlying chronic pain in PTLS by comparing a group of PTLS patients and healthy participants on brain imaging, sensory, and immune markers; and (b) assess change in pain, brain imaging (fMRI and MRS), sensory, and immune markers in response to a combination of SNRI and glutamatergic treatment for chronic pain in PTLS (Milnacipran and D-cycloserine).
This study evaluates the safety of Niclosamide in patients with colon cancer that are undergoing primary resection of their tumor. This is a phase I study with three dosage levels to determine the maximum tolerated dose (MTD).
This study is a multi-center, randomized, unblinded, clinical trial. The objective is to determine if catheter-based atrial fibrillation (AF) ablation is superior to medical treatment in patients with impaired left ventricular (LV) function who have been diagnosed with symptomatic AF within the past 12 months.
The goal of the study is to compare the safety and efficacy of molecular water and bland aerosol therapy (particulate water) in providing adequate humidity to the inspired gas of spontaneously breathing tracheostomy patients.
