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.
Dry eye is the most common reason for visit to an ophthalmologist's office. The prevalence is on the rise and is mainly attributed to factors such as increased environmental pollution and contact lens use. The current management options are limited to over the counter artificial tear drops and three FDA-approved drugs. Of these, cyclosporine has been used worldwide for treating mild to moderate dry eyes. The earlier version consisted of 0.05% cyclosporine which worked well for a limited number of inflammatory dry eye conditions. Recently, 0.09% cyclosporine was approved by the FDA. The nearly double concentration is expected to be more beneficial for severe inflammation which is often seen in Sjögren syndrome and other Rheumatological conditions associated with dry eyes. In this pilot project, the investigator proposes to evaluate the change in expression of SLURP1 and other markers of ocular surface inflammation before and after treatment with 0.09% cyclosporine eye drops.
This is a single center study of 60 subjects including those with asthma and mucus plugging, those with asthma and without mucus plugging, and healthy controls. Screening data will be reviewed to determine participant eligibility. Participants who meet all inclusion criteria will participate in image-guided bronchoscopy ("virtual navigation bronchoscopy" [VNB]) to sample airway biospecimens in mucus plugged and control airways.
This open label, between-subject, randomized multi-center pilot study will assess the feasibility of conducting a study remotely with telehealth visits to assess the effect of cigarettes with minimal filter ventilation vs. moderate filter ventilation on smoking behavior and biomarkers of tobacco toxicant exposure. Subjective measures, alveolar carbon monoxide, blood pressure and cigarettes per a day will be collected remotely. Biological samples will be collected at home and mailed to the study clinic.
This is a prospective multicenter randomized open-label study aiming to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in achievement of long-term ventricular tachycardia (VT) treatment success.
This is a single arm, open label trial to assess the safety and efficacy of tucatinib in combination with pembrolizumab and trastuzumab for the treatment of HER2+ breast cancer brain metastases (BCBM). A total of 33 patients with untreated or previously treated and progressing HER2+ BCBM not requiring urgent central nervous system (CNS)-directed therapy will be enrolled. The study will determine the recommended dose of tucatinib in this combination and assess the efficacy of this combination in controlling CNS disease in patients with HER2+ BCBM.
110 individuals with stage 4-5 Chronic Kidney Disease (CKD) will be randomized to 1-year of blinded Evolocumab or placebo. Subjects will undergo evaluation of circulating lipids at baseline and end of study. A substudy including 50 subjects will assess myocardial rest and stress positron emission tomography (PET) at baseline and at 1-year.
The purpose of the study is to identify the presence of residual superficial and nodular basal cell carcinoma (BCC) status-post curettage and desiccation (C&D) by using optical coherence tomography (OCT).
The main objective of this study is to assess the clinical and mechanistic effect of using Ocular surface immunoglobulin (OSIG) eye drops for treating Dry Eye Disease. Therefore, the investigator will perform a prospective, phase II, randomized, placebo-controlled, double-masked, tolerability and efficacy clinical trial using OSIG-eye drops in patients with Dry Eye Disease. This clinical trial will be powered to detect efficacy of the treatment. This will be a Randomized controlled trial, in which a total of 40 subjects will be enrolled at one clinical site. Subjects will be randomly assigned to one of two groups (#1, #2), with 20 subjects per group. One group will be given placebo (Normal saline eye drops) and the other group will be given eye drops containing the study drug (OSIG). Treatment will be for eight weeks.
There is no current accepted and predictably effective ablative therapy for patients with recurrent paroxysmal atrial fibrillation after prior pulmonary vein isolation (PVI). This study will compare redo PVI with hybrid epicardial ablation incorporating posterior wall isolation and LAA clip, and redo PVI.
The study aims are to: 1) optimize the Transdiagnostic Sleep and Circadian Intervention (TranS-C) for delivery to Veterans in cardiac rehabilitation, 2) test and refine the adapted TranS-C treatment manual and protocol, and 3) conduct a pilot randomized trial to establish the feasibility, acceptability, and plausibility of the intervention protocol and study procedures.
