Active clinical trials for "Virus Diseases"

Rapid diagnosis and precise treatment have become possible with multiplex polymerase chain reaction (PCR) panels that can identify a variety of causative agents of acute respiratory illnesses such as bacterial and viral infections in one urgent care visit. While real-time PCR is currently used as a standard for diagnosing acute respiratory illnesses such as influenza due to its high sensitivity and specificity, it typically takes several hours for results which is unfavorable in the urgent care setting. Highly sensitive and rapid random-access PCR tests provide the sensitivity and specificity needed to both rapidly and accurately diagnose acute respiratory illnesses. Similar PCR panels have been used in previous research for the diagnosis of gastrointestinal illnesses in the emergency department and point-of-care testing for hospitalized adults presenting with acute respiratory illness. In this study, the investigators aim to determine if a rapid multiplex PCR test for urgent care patients with symptomatic upper respiratory infections can improve patient and provider-reported outcomes. This study utilizes the Biofire® FilmArray Panel (RP2.1-EZ) which in previous studies has been shown to be highly effective in diagnosing acute respiratory illnesses.

The purpose of this study is to evaluate the safety and immunogenicity of 2 formulations of GSK Biologicals' varicella vaccines given as a 2-dose course in the second year of life.

The purpose of this study is to determine if the use of inhaled beclomethasone after a community-acquired respiratory viral infection in a lung transplant recipient decreases the risk of the subsequent development of chronic lung allograft dysfunction.

The purpose of this study is to evaluate the efficacy and safety of amiodarone in the treatment of patients afflicted with Ebola virus disease.

This is a clinical trial in which healthy volunteers will be administered two experimental Ebola vaccines: ChAd3-EBO-Z and Ad26.ZEBOV. Four groups of volunteers will be vaccinated with both vaccines one after the other in a prime/boost regimen. All ChAd3-EBO-Z doses are 1x10^11 vp and all Ad26.ZEBOV doses are 5x10^10 vp. Group 1 will receive a ChAd3-EBO-Z priming vaccine and an Ad26.ZEBOV boosting vaccine 28 days later. Group 2 will receive an Ad26.ZEBOV priming vaccine and a ChAd3-EBO-Z boosting vaccine 28 days later. Group 3 will receive a ChAd3-EBO-Z priming vaccine and an Ad26.ZEBOV boosting vaccine 56 days later. Group 4 will receive an Ad26.ZEBOV priming vaccine and a ChAd3-EBO-Z boosting vaccine 56 days later. The study will assess the safety of the vaccinations, and the immune responses to vaccination. Immune responses are measured by tests on blood samples. The ChAd3-EBO-Z and Ad26.ZEBOV vaccines are called viral vectored vaccines. They are made from viruses which are modified so that they cannot multiply. The viruses have extra DNA in them so that after injection, the body makes Ebola proteins (but Ebola does not develop), so that the immune system builds a response to Ebola without having been infected by it. Healthy volunteers will be recruited in Oxford and London, England. The study will be co-funded by GSK Biologicals and Crucell Holland BV.

Primary objective To demonstrate that administration of V503 induces non-inferior Geometric Mean Titres (GMTs) for serum anti-HPV 6, 11, 16, and 18, compared to GARDASIL in 16- to 26-year-old men

To evaluate the immune response and the safety of a primary series schedule that includes V419 (PR5I) at 2 and 6 months of age and Pediacel at 4 months of age Primary objectives To demonstrate that the mixed schedule induces acceptable responses for Hepatitis B (HB) one month after completion of the mixed schedule To demonstrate that the mixed schedule induces acceptable responses for Haemophilus influenzae type b (Hib) one month after completion of the mixed schedule Secondary objectives To describe the antibody response to all PR5I antigens one month after completion of the mixed schedule To describe the antibody response to meningococcal serogroup C (MCC) conjugate vaccine one month after the second dose of MenC vaccine To describe the safety profile after each dose of study vaccines administered

A phase I trial conducted in a single centre, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of 2 intramuscular injections of plant-based H7 VLP Influenza Vaccine administered to healthy adults, 18-60 years of age.

Primary Research Questions: Efficacy, safety and feasibility of a 3-month course of levofloxacin in a pilot study will be assessed. Under efficacy, this pilot will determine whether levofloxacin can decrease the incidence of BK viruria and peak urine BK viral load. Under safety, this pilot will determine the incidence of adverse events with levofloxacin. Under feasibility, this pilot will determine the number of kidney transplant patients randomized over an eight month enrolment period, adherence to the levofloxacin and frequency of patient drop-out and loss to follow-up

The primary objectives of this study are to evaluate the immunogenicity and safety of concomitant administration of V419 (PR51) with 2 types of meningococcal serogroup C conjugate (MCC) vaccines to healthy infants at 3 and 4 months of age in terms of antibody seroprotection rate (SPR) to MCC. Participants also received a Haemophilus influenza type B (Hib)-MCC vaccination at 12 months of age. It was hypothesized that the SPR to MCC at 1 month post-dose 2 of either tetanus toxoid conjugated Meningo C (MCC-TT) or CRM197 conjugated Meningo C (MCC-CRM) vaccines would be acceptable when administered concomitantly with V419.
