Trial Outcomes & Findings for Safety and Immunogenicity of Different Formulations of an MF59-Adjuvanted Influenza Vaccine in Older Adults ≥50 Years of Age (NCT NCT05501561)

NCT ID: NCT05501561

Last Updated: 2026-06-30

Results Overview

Seroconversion is defined as ≥4-fold increase in titer postvaccination in those with prevaccination titer equal to or above the lower limit of quantitation (LLOQ; 1:10), or a postvaccination titer ≥1:40 for subjects with baseline titer below the LLOQ (1:10) for HI antibodies.

PRIMARY outcome

Timeframe: Day 1 and Day 29

Population: Per Protocol Set, defined as all subjects in the Full Analysis Set\* who correctly received the vaccine; had no protocol deviations leading to exclusion as defined prior to unblinding/analysis; and were not excluded due to other reasons defined prior to unblinding or analysis, including subjects who withdrew informed consent prior to Day 28. \*All subjects in the All Enrolled Set who were randomized, received study vaccination and provided immunogenicity data on Day 1 and Day 29 assessment.

GMTs on Day 1 (prior to vaccination) and Day 29 as determined by HI assay against each of the 4 vaccine strains. No hypothesis testing was performed for the primary immunogenicity objectives.

Seroconversion is defined as ≥4-fold increase in titer postvaccination in those with prevaccination titer equal to or above the lower limit of quantitation (LLOQ; 1:10), or a postvaccination titer ≥1:40 for subjects with baseline titer below the LLOQ (1:10) for HI antibodies.

PRIMARY outcome

Timeframe: Day 29

Population: Per Protocol Set Per protocol, for each of the three investigational groups, the data are analyzed together with the Licensed IIV group for the outcome measure of HI GMT ratio (Outcome Measure 5). The underlying HI GMT summary data used for this inferential calculation are reported in Outcome Measure 1.

The GMT ratio is the geometric mean of the postvaccination HI titer for the investigational vaccine over the geometric mean of the postvaccination HI titer for the licensed IIV vaccine. The Day 29 GMT ratios are calculated for the investigational vaccines with reference to the licensed vaccine, ie, the Day 29 GMT ratios are the ratio of the Day 29 GMTs in the Investigational group (IIV-A Investigational, aIIV-B Investigational, or aIIV-C Investigational) compared with the Day 29 GMTs in the Licensed IIV group (ie, Investigational group/Licensed IIV group). As the licensed vaccine is the reference for the GMT ratio, this parameter is presented as "1" for the Licensed IIV group (ie, Licensed IIV group/Licensed IIV group).

SECONDARY outcome

Timeframe: Day 29

Population: Per Protocol Set Per protocol, for each of the three investigational groups, the data are analyzed together with the Licensed IIV group for the outcome measure of MN GMT ratio (Outcome Measure 13). The underlying MN GMT summary data used for this inferential calculation are reported in Outcome Measure 10.

The GMT ratio is the geometric mean of the postvaccination HI titer for the investigational vaccine over the geometric mean of the postvaccination HI titer for the licensed IIV vaccine. The Day 29 GMT ratios are calculated for the investigational vaccines with reference to the licensed vaccine, ie, the Day 29 GMT ratios are the ratio of the Day 29 GMTs in the Investigational group (IIV-A Investigational, aIIV-B Investigational, or aIIV-C Investigational) compared with the Day 29 GMTs in the Licensed IIV group (ie, Investigational group/Licensed IIV group). As the licensed vaccine is the reference for the GMT ratio, this parameter is presented as "1" for the Licensed IIV group (ie, Licensed IIV group/Licensed IIV group).
