Active clinical trials for "Respiratory Syncytial Virus Infections"

This is a randomised, double-blind, placebo-controlled, multicentre, phase 2 study to evaluate the efficacy, safety and tolerability of orally administered AK0529 in Chinese adults with RSV infection.

The purpose of this observational study is to describe the environmental aerosolization patterns burden of RSV in the air and on surfaces in surrounding adult patients in a real-life setting. Specific objectives are to determine the particle size distribution and the quantity of airborne pathogens dispersed by symptomatic participants, to establish a spatial model of airborne emission and subsequent surface burden of RSV emission and dispersal in clinical settings (emergency department and inpatient units; 1 foot vs. 3-6 feet vs. 8-10 feet), and to obtain information regarding the potential association of illness severity and risk factors to the scale of airborne dispersal (e.g., super spreaders). This study will be used to collect data of the emission patterns of RSV. Subsequent investigations will help guide policymakers in the assessment of the airborne exposure risk to RSV and the implementation of appropriate infection prevent measures such as respirators and face masks. The investigators hypothesize that the airborne emission patterns of Respiratory Syncytial Virus varies between individual patients. The investigators are proposing to assess the particle size and spatial distribution of airborne RSV emitted by affected patients within a routine care environment: Characterize individuals who develop respiratory illnesses caused by RSV in terms of demographics, co-morbid conditions, prior vaccinations (e.g., influenza vaccine, DTAP), use of antivirals, and severity of illness (fever, respiratory symptoms, malaise). Determine the particle size distribution patterns and quantities of the pathogen in two settings, an emergency department and an inpatient unit (ICU and non-ICU settings). Establish a spatial model (1 foot vs. 3-6 feet vs. 8-10 feet) of airborne pathogen dispersal and subsequent surface burden in two settings, an emergency department and an inpatient unit (ICU and non-ICU settings). Determine the correlation between the human aerosolization patterns and the severity of illness (fever, respiratory symptoms, malaise) in individual participants (super spreader?).

A Multicenter Study Conducted to Evaluate the Performance of the LumiraDx SARS-CoV-2 & FLU A/B Test, and LumiraDx SARS-CoV-2 & RSV Test at Point of Care Testing Sites. Subjects presenting with symptoms suggestive of COVID-19 and/or Influenza and/or RSV will be consented and asked to donate swab sample(s) for testing in the device(s) under evaluation.

Respiratory Syncytial Virus (RSV) is a virus that causes chest infections. It is the single most important cause of severe respiratory illness in infants and young children, and severe RSV infection early in life is associated with an increased risk of later developing asthma. RSV also causes severe disease in elderly and immune-compromised adults, and the amount of RSV disease in the elderly is similar to that from seasonal flu. The virus is transmitted in the secretions of the upper respiratory tract of infected individuals and by contact with contaminated surfaces (such as toys). Hospital outbreaks, especially on paediatric and neonatal wards, are not uncommon. Infection by RSV does not develop a natural long-lasting protection against re-infection (like, for example, measles does). In the USA nearly all children by 24 months of age have been infected at least once with RSV, and about half will have experienced two infections. There is no effective anti-viral drug to treat an infection and the only way of managing cases of severe infection is through supporting organs, such as the lungs, to withstand and recover from the illness. There remains a real need to develop an effective vaccine to prevent severe infections caused by RSV. A better understanding of the way the immune system responds to RSV in children would aid the development of such a vaccine. The purpose of this study is to increase our understanding of how the immune system responds to RSV. Only limited data is available on some important components of the immune response and this study is designed to measure these in more detail. This is done using a single blood sample. A total of 35 children are anticipated to be recruited to this study, at ages when we expect to see differences in the immune response to RSV; 5 infants aged between 2 and 4 months (Group 1), who have not yet been exposed to RSV 20 infants aged between 6 and 12 months (Group 2), who will have had exposure to one single RSV season in the winter of 2011/12 10 children aged between 3 and 6 years (Group 3), who have been exposed to RSV over several winter seasons

This research study involves studying the genes that may affect how ill you become during respiratory infection with respiratory syncytial virus (RSV). RSV is a virus that often causes common colds. Cytokines are chemicals that are naturally made by your body. Cytokine levels are increased in some people when they have common colds or wheezing caused by respiratory syncytial virus (RSV). The purpose of this study is to study the genes that may control cytokine levels during infection with RSV in the elderly population.

The study will be conducted using nasopharyngeal swab specimens collected prospectively from individuals suspected of having the signs and symptoms of an acute respiratory tract infection caused by a respiratory virus. A series of standard viral culture tests validated for routine use in the clinical laboratory, and/or a series of PCR-based Laboratory Developed Tests (PCR-LDT) validated by a central reference laboratory will be used to verify the performance of the investigational artus Influenza A/B RT-PCR test and the QIAGEN ResPlex II Advanced Panel test. From each specimen five (5) aliquots will be prepared: (a) one aliquot will be tested in real-time using the assigned viral culture reference methods; (b) one aliquot will be used to extract nucleic acid in real-time for investigational testing; (c) one aliquot of the specimen will be stored at --70C for subsequent shipment to the reference laboratory for PCR-LDT testing, (d) one aliquot will be archived at -70C for subsequent follow-up by the reference laboratory (e.g., bi-directional sequencing of positive specimens), and (e) any remaining specimen will be stored for the Fresh vs. Frozen Study. The extracted nucleic acid generated from the second aliquot (i.e., "b" above) will be split and subjected to testing by both the artus Influenza A/B RT-PCR test and the ResPlex II Advanced Panel test.

The purpose of this study is to collect clinical outcome and nasal viral load information.

Approximately 600 pediatric patients prescribed palivizumab (Synagis) prophylaxis in usual practice according to the approved Korean product label will be registered into this observational study. Baseline data will be obtained at enrollment including demographics, gestational age, birth weight and underlying diseases and complications especially in regard to respiratory disease and cardiovascular disease. At routine visits for Synagis administration, which will occur according to usual medical practice, information on Synagis prophylaxis, concomitant medication, and adverse events will be collected for up to 30 days after the last administration of Synagis.

The study was designed to gather information regarding the use of palivizumab for the prophylaxis for respiratory syncytial virus (RSV) infection in high-risk infants in selected countries within Latin America.

Retrospective medical record review study of specific adverse events in children with congenital heart disease who received palivizumab for prophylaxis of serious respiratory syncytial virus infection and control subjects that did not receive palivizumab
