Active clinical trials for "Respiratory Syncytial Virus Infections"

A Non-Randomized, Open-Label, Two-Part, Drug-Drug Interaction Study to Evaluate the Effects of Cyclosporine and Prednisone on the Pharmacokinetics and Safety of EDP-938 in Healthy Adult Subjects

A Non-Randomized, Open-Label, Three-Part, Drug-Drug Interaction Study to Evaluate the Effects of tacrolimus, dabigatran, rosuvastatin and midazolam on the Pharmacokinetics and Safety of EDP-938 in Healthy Subjects

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of ALS-008176 following oral administration of single ascending dose of ALS-008176 in healthy Japanese adult participants.

The purpose of this study is to infect healthy volunteers aged 60-75 years old with Respiratory Syncytial Virus (RSV) to confirm how safe and well tolerated the use of an experimental RSV virus is in a population that has not previously received the virus. Additionally, this study will also look at various components of the volunteers' blood, the lining of their noses and other samples in order to measure the effects of the virus on the body, in particularly the immune system before, during and after viral infection.

A Non-Randomized, Open-Label, Three-Part, Drug-Drug Interaction Study to Evaluate the Effects of Itraconazole, Rifampin, and Quinidine on the Pharmacokinetics and Safety of EDP-938 in Healthy Subjects

The purpose of this long-term follow-up (LTFU) study is to evaluate the incidence of the clinical diagnosis of asthma and the frequency of wheezing in infants and children with respiratory syncytial virus (RSV) infection who were treated with (lumicitabine or placebo) and have completed their last planned study-related visit in a feeding Phase 2 study (64041575RSV2004).

A total of 96 subjects will be recruited into 5 groups. Each subject will receive either two vaccinations with MVA-BN-RSV vaccine or placebo.

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of a single intramuscular dose of the investigational respiratory syncytial virus (RSV) maternal (RSV MAT) vaccine during subsequent uncomplicated pregnancy in maternal participants, 18 to 49 years of age (YOA), who have previously received the RSV MAT vaccine or placebo in the RSV MAT-004 (NCT04126213), RSV MAT-009 (NCT04605159) and RSV MAT-012 (NCT04980391) primary studies.

The purpose of this study is to assess the safety, reactogenicity and immunogenicity of the investigational GSK RSV vaccine in pregnant women aged 18 to 40 years and infants born to the vaccinated women

Respiratory viruses including influenza and respiratory syncytial virus (RSV) are among the most important causes of severe disease globally, infecting everyone repeatedly throughout life. Understanding of how to prevent infection is incomplete but boosting immunity with vaccines remains the best strategy. T cells have been shown in animals to be essential for clearing respiratory viral infection and are likely to be helpful if stimulated by vaccines. However, where these cells originate from and how they develop in the human lung are still unclear. The investigators will inoculate volunteers with influenza or RSV to examine the relationship between T cells in their blood and lungs and the outcome of infection. By tracking these specialised cells, the investigators aim to develop a better understanding of how they are generated in order to harness them with future vaccines.
