Trial Outcomes & Findings for A Study of an Ad26.RSV. preF-based Vaccine in Adults Aged 18 to 59 Years, Including Adults at High Risk for Severe RSV Infection (NCT NCT05070546)

NCT ID: NCT05070546

Last Updated: 2025-05-25

Results Overview

Number of participants with solicited local AEs at 7 days post-vaccination in Cohorts 1 and 2 were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited local AEs were predefined local events (at the injection site: erythema, pain/tenderness and swelling) that were by definition considered as related to the study vaccine and collected within 7 days after vaccination.

PRIMARY outcome

Timeframe: 7 days after vaccination on Day 1 (Day 8)

Population: Full analysis set (FAS) included all participants who received study vaccine, regardless of the occurrence of protocol deviations and vaccine type (study vaccine or placebo). Here 'N' (number of participants analysed) signifies number of participants who were evaluable for this outcome measure. This outcome measure was planned to be analysed for specified cohorts only.

Number of participants with solicited local AEs at 7 days post-vaccination in Cohorts 1 and 2 were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited local AEs were predefined local events (at the injection site: erythema, pain/tenderness and swelling) that were by definition considered as related to the study vaccine and collected within 7 days after vaccination.

Timeframe: 14 days after vaccination on Day 1 (Day 15)

Population: The Per-protocol Immunogenicity (PPI) set included all randomised participants on Day 15 who received study vaccine and for whom immunogenicity data were available. Here 'N' (number of participants analysed) signifies number of participants who were evaluable for this outcome measure. This outcome measure was planned to be analysed for specified arms only. As planned, combined data of participants aged 18-59 years Cohorts 1 (Group 1) and 2 (Group 3) has been reported.

RSV A2 strain neutralizing antibody titers of the vaccine-induced immune response was assessed through virus neutralization assay and were expressed as 50% inhibitory concentration (IC50) units.
