Active clinical trials for "Virus Diseases"

To evaluate impact of Health Belief Model Based Education on Human Papilloma Virus Infection and Vaccination among University Students

We propose a randomized controlled trial (RCT) of the Skin intervention, compared to an assessment-only condition (both groups receive rapid HIV testing, a review of testing results, and brief HIV prevention counseling) among 350 injection drug users recruited during an acute medical hospitalization at Boston Medical Center. In the general hospital setting, injection drug users who otherwise might not seek care are accessible and teachable, and the presence of a drug-related illness can set the stage for patients to be more receptive to interventions2. We hypothesize that the Skin intervention will produce better outcomes at 1-, 3-, 6-, 9-, and 12-month(s) post-intervention.

This study will determine whether three manufacturing lots of V419 (PR5I) induce similar immune responses to all of the antigens contained in V419 when given concomitantly with Prevnar13™ and RotaTeq™.

Polyomavirus BK nephropathy is a serious complication after renal transplantation leading to graft loss in 40% of cases. Since no virustatic drug exists, the investigators want to study the best way to manage viral invasion by changing the immunosuppressive treatment comparing two treatment schemes. The investigators hypothesis is that switching to an mTOR-based scheme is superior to a general decrease of a calcineurin inhibitor (CNI)-based scheme. The study will be performed as a prospective, randomized, parallel group comparison.

The aim of this study is to assess the prevalence and arrhythmogenic role of occult myocardial scars on Cardiac Magnetic Resonance (CMR) in a population of patients with history of laboratory-proven symptomatic COVID-19 infection managed without hospitalization, as compared to a population of age- and sex-matched healthy volunteers.

The purpose of this study is to evaluate the long-term persistence of immune responses approximately 5 years or more after simulated rabies post-exposure prophylaxis provided in 2012 according to Essen (1-1-1-1-1) or Zagreb (2-1-1) intramuscular (IM) regimens in the subset of subjects who participated in the parent study (V49_24 [NCT01680016]) who were aged ≥6 and ≤17 years at the time of enrollment. This study is aimed to respond to a post-marketing commitment by the China Food and Drug Administration (CFDA) requested at the time of the renewal of the purified chicken-embryo cell rabies vaccine license in China, granted in August 2015.

MOSAIC is a single-blind experimental medicine study to determine the extent to which different prime-boost combinations of model immunogens based on HIV-1 envelope proteins influence the diversity of B and T cell responses.

This post-marketing surveillance (PMS) study for Sovaldi® tablets (sofosbuvir, SOF) administered in combination with Copegus® tablets (ribavirin, COPE) will evaluate the safety and efficacy of SOF administered in combination with ribavirin under real world use in Japan. Among adult patients with chronic genotype 2 hepatitis C virus (HCV) infection and treated with SOF+ribavirin in routine clinical use, the primary objective of this study is to evaluate the incidence of adverse drug reactions (ADRs) under real world settings.

The study is a double-blind (within dose level), placebo-controlled Phase I study to assess the safety, reactogenicity and tolerability of two intranasal dose levels of SynGEM®: a low dose level (140 μg F-protein/2mg BLPs) and a high dose level ( 350 μg F-protein/5mg BLPs), each administered twice according to a prime-boost schedule 28 days apart at Day 1 and Day 29. The two dose levels will be recruited sequentially. Immunogenicity end-points will include assessment of humoral and cellular responses at selected time-points.

This prospective, surveillance study will assess the operational Zika virus definition for use in future Zika purified inactivated virus (ZIKV) vaccine efficacy trials in order to identify Zika virus disease (ZVD) cases among the study cohort.
