Filter by:To establish the relative accuracy of the LIAISON® NES Flu A/B, RSV & COVID-19 assay for viral nucleic acid targets from professionally collected or patient self-collected dry nasal (NS) swabs and to establish the relative accuracy of the LIAISON PLEX® RSP Flex assay from NS and nasopharyngeal swabs (NPS) in applicable transport media from human patients exhibiting clinical signs and symptoms of a respiratory tract infection.
The goal of this clinical study is to prove the no less immunogenicity of the Grippol Quadrivalent vaccine compared to the Grippol plus vaccine in children aged 6 months to 5 years (inclusive) for three identical strains of the compared vaccines in terms of the "proportion of vaccinated with seroconversion in paired sera of the hemagglutination inhibition reaction obtained before and after vaccination".
The goal of this prospective, digital randomized controlled trial is to evaluate the effectiveness of a predictive ILI detection algorithm and associated alerts during influenza season for adults living in the contigent United States. The main study objectives are to assess the effectiveness of predictive ILI detection algorithm and associated alerts on protective behaviors related to ILI and assess the accuracy of a predictive ILI detection algorithm using participant self-reported ILI symptoms and diagnosis.
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.
The study is designed as a prospective, multicentric, clinical study to investigate the positive percent agreement (PPA) and negative percent agreement (NPA) of the Panbio™ COVID-19/Flu A&B Panel using anterior nasal swab specimens tested directly, relative to the comparator methods, Roche cobas® SARS-CoV-2 (K231306) and Quidel Lyra® Influenza A+B Assay(K230236) (RT-PCR) in symptomatic patients suspected of respiratory viral infection by a healthcare provider.
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.
