Trial Outcomes & Findings for A Study to Investigate the Safety and Immunogenicity of the Quadrivalent Influenza mRNA Vaccines in Adults Aged 18 Years and Above (NCT NCT06361875)

NCT ID: NCT06361875

Last Updated: 2026-08-04

Results Overview

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study vaccine, whether or not considered related to the study vaccine. An unsolicited AE is an observed AE that does not fulfill the conditions of solicited reactions, that is, pre-listed in the case report form in terms of diagnosis and onset window post-vaccination. Systemic AEs are all AEs that were not injection or administration site reactions. Immediate events are recorded to capture medically relevant unsolicited systemic AEs which occur within the first 30 minutes after vaccination.

Participant Flow

The study was conducted at 19 centers in 2 countries from 01 April 2024 to 09 June 2025. QIV mRNA= Quadrivalent influenza modified messenger ribonucleic acid vaccine; QIV-SD= Standard dose quadrivalent influenza vaccine; RIV4= Quadrivalent recombinant influenza vaccine; QIV-HD= High dose quadrivalent influenza vaccine.

A total of 908 participants were enrolled and randomized in the study. Randomization was stratified by cohort and age group (18 to 64 years and \>= 65 years). Participants were assigned to either QIV mRNA groups, QIV-SD, RIV4 or QIV-HD (only for participants aged 65 years and above) in a ratio of allocation between 2 groups as 1:1 or 1:2.

Population: The mFAS included participants who had received the study vaccine.

An SAE is any untoward medical occurrence that at any dose results in death or is life-threatening or requires inpatient hospitalization or prolongation of existing hospitalization or results in persistent or significant disability/incapacity or is a congenital anomaly/birth defect or is an important medical event. An AESI (serious or non-serious) is 1 of scientific and medical concern specific to the Sponsor's study vaccine or program, for which ongoing monitoring and rapid communication by the investigator to the Sponsor can be appropriate. The AESIs was defined as anaphylactic reactions (including bronchospasms, and laryngeal spasms), Guillain-Barré syndrome, neuritis (including Bell's palsy), myocarditis, pericarditis, myopericarditis and vasculitis.

PRIMARY outcome

Timeframe: Day 29

Population: The mFAS included participants who had received the study vaccine. During the study, participants miss few scheduled site visits for sample collection and only participants with data collected at Day 29 are reported.

The seroconversion was defined as titer \<10 on Day 1 and post-injection titer \>=40 on Day 29; or defined as titer \>=10 on Day 1 and a \>=4-fold increase in titer on Day 29. The 95% CI for the single percentage was based on the Clopper-Pearson method. The percentages are rounded off to the tenth decimal place.

SECONDARY outcome

Timeframe: Days 1 and 29

Population: As stated in the Clinical Study Report, samples for the assessment of neutralizing antibodies were not collected from study participants. Consequently, no neutralizing antibody analyses were conducted. Furthermore, as the study has been completed, the sponsor does not intend to collect samples or perform neutralizing antibody analyses in the future.

The NT Ab was planned to be measured using seroneutralization (SN) measurement method. The 95% CI was planned to be calculated using the Clopper-Pearson method.
