Results Overview

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Injection site AEs of pain/tenderness, swelling, and redness/erythema were assessed.

PRIMARY outcome

Timeframe: Up to 5 days after any study intervention

Population: All randomized participants who received at least one dose of study intervention and received the dose relevant to the data collection time point. Participants were pooled by dose of study intervention administered due to the study's termination prior to most participants receiving their planned second dose.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Injection site AEs of pain/tenderness, swelling, and redness/erythema were assessed.

SECONDARY outcome

Timeframe: Days 1, 15, 29, 57, 71, and 85

Population: All randomized participants without deviations from the protocol that may substantially affect the results of the immunogenicity endpoint, and who had available data at the indicated time point. Participants were pooled by dose of study intervention administered due to the study's termination prior to most participants receiving their planned second dose. Data were not collected for planned timepoints on days 115, 211, 365, 422, and 534 due to early termination.

Serum samples were collected and the titers of serum neutralization antibodies were assessed using PNA. Geometric mean titers were calculated using a constrained longitudinal data analysis (cLDA) method where the response vector consisted of the log transformed pre-vaccination and post-vaccination antibody titers. The point estimates were calculated by exponentiating the estimates of the mean of the natural log values; and the within-group 95% confidence intervals (CIs) were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

SECONDARY outcome

Timeframe: Days 1, 15, 29, 57, 71, and 85

Population: All randomized participants without deviations from the protocol that may substantially affect the results of the immunogenicity endpoint, and who had available data at the indicated time point. Participants were pooled by dose of study intervention administered due to the study's termination prior to most participants receiving their planned second dose. Data were not collected for planned timepoints on days 115, 211, 365, 422, and 534 due to early termination.

Serum samples were collected and the concentrations of total anti-spike IgG antibodies were assessed using ELISA. Geometric mean concentrations were calculated using a cLDA method where the response vector consisted of the log transformed pre-vaccination and post-vaccination antibody titers. The point estimates were calculated by exponentiating the estimates of the mean of the natural log values; and the within-group 95% confidence intervals (CIs) were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.
