Trial Outcomes & Findings for A Study to Learn About How Trumenba Vaccine Shots Work Against Gonorrhea Infection in Teenagers and Young Adults in the United States. (NCT NCT05873751)

NCT ID: NCT05873751

Last Updated: 2025-04-17

Results Overview

Number of participants (cases) with infection of interest were reported. If a participant had repeated infection only first occurrence was considered, hence one participant with infection was counted only once. VE was calculated as 1 minus the hazard ratio (HR) multiplied by 100. VE is reported as part of statistical data in this outcome measure. The index date (zero time) was the date of the last dose of Trumenba vaccination, after at least one dose of MenACWY for the exposed cohort and first date of MenACWY vaccination for the unexposed cohort.

Participant Flow

Participants (15-30 years of age) who received at least one dose of Trumenba and at least one dose of MenACWY prior to their Trumenba vaccination, between 01 January 2016 and 31 December 2021, were identified and their data (01 January 2016 to 31 December 2022) was retrieved from "IQVIA PharMetrics Plus" database. Available retrospective data was evaluated per objectives of the study during approximately 11 months.

PRIMARY outcome

Timeframe: During follow-up of maximum of 83.5 months (from 14 days after the index date up to 31 December 2022; available retrospective data evaluated for approximately 11 months of this study)

Population: All eligible participants whose data were included in this retrospective study.

Number of participants (cases) with infection of interest were reported. If a participant had repeated infection only first occurrence was considered, hence one participant with infection was counted only once. VE was calculated as 1 minus the hazard ratio (HR) multiplied by 100. VE is reported as part of statistical data in this outcome measure. The index date (zero time) was the date of the last dose of Trumenba vaccination, after at least one dose of MenACWY for the exposed cohort and first date of MenACWY vaccination for the unexposed cohort.
