NCT05966090
To assess the ability of RSVPreF3 OA investigational vaccine to generate an immune response when given in combination with HZ/su vaccine and its safety in older adults, aged \>=50 years of age.
NCT04068792
The purpose of this two-part designed study is to assess in the setting of a planned early interception of pediatric RSV disease, early viral and disease kinetics (observational stage) and the antiviral effects of an Respiratory Syncytial Virus (RSV) fusion inhibitor, JNJ-53718678 (interventional stage). In the observational stage the infant is closely monitored for early symptoms by the parent(s)/caregiver(s) and thus may be brought in for diagnosis earlier than in the typical setting.
NCT04086472
The primary objective of this study is to determine if a single intravenous (IV) dose of clesrovimab when administered at 1 of 4 dose levels results in a reduction in viral load after intranasal inoculation (with RSV A Memphis 37b) compared to IV placebo. It is hypothesized that at least 1 of the 4 dose levels of clesrovimab given prior to inoculation will reduce the area under the viral load-time curve (VL-AUC) from Day 2 through Day 11 (inclusive) after viral inoculation (Study Day 31 through Day 40) compared to placebo.
NCT03026348
This is a randomized, observer-blind, trial in clinically-stable older adults. Up to 300 eligible older adults 60 through 80 years of age will be enrolled at a 1:1 ratio into multiple dose/formulation treatment arms. Safety and immunogenicity data through Day 56 will be used to select a vaccine candidate to potentially evaluate in a Part 2 study. Proportions of subjects in various strata will not be pre-specified and the goal will be to achieve an approximately equal distribution of subjects with these characteristics across the treatment groups. Serology measures consistent with the study outcomes will be reported.
NCT01249625
Despite widespread use of respiratory protective equipment in the U.S. healthcare workplace, there is very little clinical evidence that respirators prevent healthcare personnel (HCP) from airborne infectious diseases. Scientific investigation of this issue has been quite complicated, primarily because the use of respirators has become "the standard of care" for protection against airborne diseases in some instances, even without sufficient evidence to support their use. The key question remains: How well do respirators prevent airborne infectious diseases? The answer to this important question has important medical, public health, political and economic implications.
NCT02561871
The purpose of this study is to assess the safety and tolerability of intramuscular prime-boost regimens of Ad26.RSV.FA2 given either once or twice followed by Ad35.RSV.FA2 (human adenovirus-vectored vaccine candidate) in healthy participants.
NCT00585481
The primary objective of this study is to determine the incidence of severe RSV LRTI requiring hospitalization among infants born \< 35 weeks gestational age for one year of follow-up.
