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.
Direct antiviral therapy (standard of care) administered to chronic hepatitis C-infected patients, in two hepatology clinics, who had used intravenous drugs in the past 6 months of signing informed consent (IC). This cohort was compared to concurrently treated chronic hepatitis C patients who were not intravenous drug users, who signed IC in these same clinics. Follow-up expected two years after cure and relapse rates recorded. Primary end point was SVR rate and secondary end points included reinfection rates in follow-up period.
To quantify myopic progression (cycloplegic spherical equivalent refraction - cSER) following the cessation of use of specific spectacle lenses. To quantify axial length progression following cessation of use of specific spectacle lenses.
This study has one primary objective and two secondary objectives, with an overall goal of understanding barriers to vaccination and vaccination confidence, so that effective interventional strategies can be further developed and tested to improve vaccination outcomes in a community healthcare setting.
Phase 2b, randomized, double-masked, parallel-group, active-controlled, multicenter, 36-week study designed to assess the safety and efficacy of suprachoroidally administered CLS-AX 1.0 mg with a flexible dosing regimen in participants with neovascular age-related macular degeneration previously treated with intravitreal anti-vascular endothelial growth factor (VEGF) standard of care therapy. Only one eye will be chosen as the study eye.
The study is being conducted to understand how the medicine, semaglutide, affects the immune system and other biological processes in people with Alzheimer's disease. Semaglutide is a medicine that doctors can prescribe in some countries for the treatment of type 2 diabetes and excess body weight. This study will help us understand whether semaglutide can also be used for the treatment of Alzheimer's disease. The study will last for about 77 weeks. In the first 12 weeks of treatment, participants will either get semaglutide (active medicine) or placebo (inactive dummy medicine). Which treatment participants get is decided by chance. In the following 52 weeks of treatment, all participants taking part in the study will get semaglutide. Participants must have a study partner, who is willing to take part in the study. Participants will get study medicine in a pen injector. The study partner will need to inject the study medicine into the skin of participant's stomach, thigh or upper arm once every week.
The primary objective of the study is to evaluate the pharmacokinetics (PK) of multiple cytochrome P450 (CYP450) substrates alone and in combination with rocatinlimab in participants with moderate to severe atopic dermatitis (AD).
Evaluate the long-term effectiveness of implementing vouchers as a linkage strategy in a population requiring recovery support services (RSS) when no other funding sources are available. A within-subjects study design will be used to test the effectiveness of the Kentucky Access to Recovery (KATR) last resort voucher linkage approach to reduce the risk of nonfatal and fatal overdoses by (a) increasing an individual's recovery capital; (b) reducing resumption of illicit substance use; and (c) promoting relinking to RSSs if illicit substance use is resumed.
The study will be the first to assess the impact of nicotine concentration on compensatory puffing (total inhaled volume), nicotine delivery, and switch patterns (percent exclusive EC, dual cig-EC, and cig only users) with an explicit focus on AA and White smokers.
The purpose of this pilot randomized factorial trial is to test the feasibility, acceptability, and effects of a theory-based mobile physical activity and nutrition intervention designed specifically for young adult cancer survivors to increase physical activity and diet quality.
The purpose of this registry is to evaluate the safety and effectiveness of LBBA pacing/sensing in patients already implanted with the Tendril STS 2088 lead.
