Filter by:The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.
This study is a prospective, multicenter, randomized controlled trial and aims to evaluate efficacy and safety of Xuanfei Baidu Granule in the treatment of influenza A. This study plans to enroll 584 subjects. The subjects will be randomly divided into 4 groups according to the ratio of 1:1:1:1, and they will be treated with Xuanfei Baidu Granule Placebo, Xuanfei Baidu Granule, Xuanfei Baidu Granule combined with Baloxavir Marboxil tablet.1 bag of Xuanfei Baidu Granule and Xuanfei Baidu Granule Placebo in the morning and evening, and take with boiling water for 5 days. Baloxavir Marboxil Tablet was taken orally 2 tablets, once a day for 1 day. The subjects were visited every day for 7 days after enrollment.
The Metrix COVID/Flu Test will be evaluated for use in Point-of-Care and Non-Laboratory settings in a home testing environment utilizing the clinical study design described herein. The study will take place in simulated home environments which will be set up within or near active clinical settings (e.g., urgent care facilities). This will be a prospective study conducted at three or more investigational sites located within the United States for the clinical validation of the Metrix COVID/Flu Test for the differential detection of SARS-CoV-2, Influenza A, and Influenza B in AN swab or saliva samples. Additional sites may be added to the study in order to meet minimum subject/sample enrollment requirements and geographic prevalence of respiratory virus infections. One or more investigational sites outside of the US (at which participants are required to be fluent in English) may also be included in the study depending on enrollment needs and geographical/seasonal prevalence of respiratory virus infections. Comparator testing will be performed to determine the infection status of each sample for comparison to results generated by the candidate test. The primary comparator for the study will be an FDA-cleared assay for the detection of SARS-CoV-2, Flu A, and/or Flu B.
The primary objective of this clinical performance study is to evaluate and further validate the clinical performance of: 1. ClariLight Influenza A/B & SARS-CoV-2 test kits and 2. ClariLight Influenza A/B & RSV test kits, for the qualitative detection and differential diagnosis of SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus (RSV) present in anterior nasal and oropharyngeal swab, in combination with an automated molecular diagnostic analyzer and sample collection tube by comparing them against a CE marked, in-vitro diagnostic device, used in the standard of care.
Participants in this study will be given either CC-42344 (one of two dose levels) or placebo orally for 5 days after receiving an influenza (flu) challenge virus. Participants will not know whether they are getting placebo or CC-42344. The amount of virus in nasal samples will be measured over time. Side effects and pharmacokinetics (the amount of CC-42344 in blood) will also be measured.
This study is designed to demonstrate the performance and usability of the the Panbio™ COVID-19/Flu A&B Panel Self Test in the hands of patients/lay-users. Nasal swabs will be self-collected by subjects/lay-users who are symptomatic and suspected of viral respiratory infection. They will perform, read, and interpret the test result. The test is intended for nonprescription home use for qualitative detection of COVID-19, Influenza A antigen, and Influenza B antigen.
The purpose of this study is to assess safety and immunogenicity of H7HLAII, a DNA vaccine encoding influenza hemagglutinin (HA) from influenza A/Shanghai/2/2013 (H7N9) directed to cells expressing human leukocyte antigen class II (HLAII) molecules, for prophylaxis of pandemic H7N9 influenza infection in healthy volunteers.
To investigate the safety and tolerance of a single infusion of ProTrans® in subjects with "severe" respiratory complications associated with pneumonia caused by COVID-19, Influenza A, Metapneumovirus or RSV infection.
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.
