Filter by:This is a phase 2A, double-blind, randomized, placebo-controlled study of molnupiravir (MK-4482) in healthy participants who have been inoculated with an experimental Respiratory Syncytial Virus (RSV) [RSV-A Memphis 37b]. It is hypothesized that MK-4482 will reduce the peak viral load (PVL) compared to placebo when given either before (prophylactic) or after (treatment) RSV-A Memphis 37b inoculation. Participants arrive at the study center for check-in between Day -3 and Day -1. The assigned treatment sequence (consisting of a combination of molnupiravir or placebo) begins Day -1. Participants receive viral inoculation with RSV-A Memphis 37b on Day 0, and depart on Day 12. There is a follow-up visit on Day 28.
The purpose of this study is to assess the safety and immunogenicity of RSVpreF when coadministered with SIIV compared to sequential administration of the vaccines when given 1 month apart (SIIV followed by RSVpreF). Additionally, the study will contribute data supporting the development of RSVpreF as a prophylactic vaccine against RSV disease in infants through maternal immunization and in older adults through active vaccination.
This was a randomized, double-blind, placebo-controlled, multicentre, phase 2 study to evaluate the efficacy, safety and tolerability of orally administered EDP-938 in adults with RSV infection.
The purpose of this study is to assess the safety and reactogenicity of an intramuscular regimen of 3 doses of 2.5*10^10 viral particles (vp) of adenovirus serotype 26 based respiratory syncytial virus pre-fusion protein (Ad26.RSV.preF) vaccine in RSV-seronegative toddlers aged 12 to 24 months.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and incidence of anti-drug antibodies (ADAs) of single ascending doses of clesrovimab in healthy pre-term (born at 29 to 35 weeks gestational age) and full-term (born at >35 weeks gestational age) infants. Participants will be randomized into 1 of 4 dose escalation panels (Panels A to D); an additional panel (Panel E) of full-term infants will receive the same dose as Panel D. Key safety and tolerability variables will be reviewed after each dose panel prior to administering the next-highest dose.
Background: Respiratory Syncytial Virus (RSV) is a virus that infects the lungs and breathing passages. Healthy adults who are infected generally have mild cold symptoms for a week or two. But it can also be serious, especially for infants and older adults. It can be spread by direct or indirect contact with respiratory secretions. Researchers want to study a new vaccine to prevent RSV. Objective: To see if a vaccine for RSV is safe and if it causes side effects. Eligibility: Healthy adults 18-50 years old Design: Volunteers were screened in a separate screening protocol. Subjects had 13 visits over 1 year. Some subjects received just vaccine. Some received vaccine mixed with alum adjuvant. All subjects received their dose by injection in the upper arm. They received up to two doses, one at the beginning of the study and another 12 weeks later. Subjects were monitored for 1 hour after injection and called to check on their safety 1 day after. Subjects recorded their temperature and side effects for 7 days after each vaccination. Subjects were provided with a thermometer to measure their temperature and a ruler to measure any changes if these occurred on their skin at the injection site. At all visits, subjects were checked for health changes or problems. They may have had blood drawn. At some visits, subjects had samples collected from their nose and mouth.
This randomized, double-blind, placebo-controlled phase 2 trial will be conducted at a single tertiary pediatric intensive care unit (PICU). The study will include children with RSV infection who were admitted to the pediatric intensive care unit and require respiratory support via positive pressure ventilation (invasive and noninvasive).
Administration of DPX-RSV(A), a Respiratory Syncytial Virus vaccine containing Respiratory Syncytial Virus (RSV) SHe antigen and DepoVaxTM adjuvant to healthy adults ≥50-64 years of age.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of an extended half-life anti-respiratory syncytial virus (RSV) monoclonal antibody compared to placebo when administered to healthy preterm infants.
The primary objective of this study is to evaluate the effect of presatovir on respiratory syncytial virus (RSV) viral load in autologous or allogeneic hematopoietic cell transplant (HCT) recipients with an acute RSV upper respiratory tract infection (URTI), the effect of presatovir on development of lower respiratory tract complication, being free of any supplemental oxygen progression to respiratory failure, and pharmacokinetics (PK), safety, and tolerability of presatovir.
