Filter by:The main goal of this research study is to use data from activity trackers (such as Fitbits), lab tests, and surveys to see if activity, sleep, and heart rate data can tell the difference between when someone has a respiratory illness (e.g., flu) and when they are feeling healthy. The research will also study an investigational flu@home test and app. If successful, results from the study could be used in the future to better identify people with respiratory illness. In addition, this study will test the accuracy of an at-home flu test kit compared to laboratory test results.
This is a phase 1 study in which healthy volunteers will receive VIR-2482 or placebo and will be assessed for safety, pharmacokinetics, and immunogenicity of VIR-2482 in preventing Influenza A illness.
The purpose of this study is to evaluate the antiviral effect, as measured by the time to alleviation of influenza symptoms and viral titer in nasopharyngeal secretions in adults with acute uncomplicated influenza A following administration of ZSP1273.
This is a Phase I double-blind, randomized, placebo-controlled study in 250 healthy adults, 18-49 years of age, inclusive, who are in good health and meet all eligibility criteria. The purpose of this dose escalation clinical study is to assess the safety, tolerability/reactogenicity, and immunogenicity of H3N2 M2SR investigational vaccines for prevention of influenza, when delivered at higher dosages or in two doses . Eligible subjects will be screened and randomized to receive two administrations 28 days apart of Sing2016 M2SR at three dose levels (low, medium, high), Bris10 M2SR at one dose level (low), or placebo in a 1:1:1:1:1 ratio. Study duration will be approximately 8 months with subject participation duration approximately 7 months. The primary study objective is to assess the safety and reactogenicity of a monovalent live single replication influenza H3N2 M2SR vaccine.
The purpose of this study is to evaluate the body's immune response at different time points to an FDA-approved seasonal influenza vaccine. By better understanding the way the immune system responds to the influenza vaccine, the investigators can design more effective vaccines against influenza.
The present clinical phase I study designed to examine the safety, reactogenicity and immunogenicity of the medicinal product - Vaccine vector against influenza A - in healthy volunteers after a single dose in the three groups with dose escalation.
This study is a Phase IIb, Randomized, Double-blind, Multicenter, Placebo-controlled study evaluating the efficacy and safety of CT-P27 in subjects with acute uncomplicated influenza A infection.
The purpose of this study is to evaluate the clinical and virologic benefit of pimodivir in combination with Standard-of-Care (SOC) treatment compared to placebo in combination with SOC treatment.
The purpose of this study is to evaluate the clinical and virologic benefit of pimodivir in combination with Standard-of-Care (SOC) treatment compared to placebo in combination with SOC treatment.
It is well recognized that respiratory viruses cause substantial disease burden every year. Among all known respiratory viruses, influenza virus is the greatest cause of disability-adjusted life years lost, excess hospitalizations, and deaths in the elderly and patients with chronic illness. These patients are frequently hospitalized for pneumonia secondary to these respiratory viral infection. Recently, macrolide antimicrobial clarithromycin and flufenamic acid (FFA) have been shown to inhibit seasonal influenza virus infection in human airway epithelial cells with additional anti-inflammatory effect. The investigators therefore plan to conduct a 3-year prospective study among adult patients hospitalized in Queen Mary Hospital for influenza with secondary pneumonia and randomized them to receive a course of oseltamivir + FFA + clarithromycin (as treatment) vs. a course of oseltamivir (current standard treatment as control). The objective of this prospective double-blind randomized controlled trial is to evaluate the efficacy of clarithromycin and FFA antiviral therapy in patients diagnosed to have pneumonia secondary to influenza infection.
