Trial Outcomes & Findings for Trial to Evaluate the Immunogenicity of Dose Reduction Strategies of the MVA-BN Monkeypox Vaccine (NCT NCT05512949)

NCT ID: NCT05512949

Last Updated: 2025-04-20

Results Overview

Venous blood was collected at Study Day 43 and the serum was analyzed via the PRNT assay to determine if GMT of the intradermal regimen of 2 x 10\^7 TCID50 MVA-BN and 1 x 10\^7 TCID50 MVA- BN were non-inferior to that of the licensed regimen of 1 x 10\^8 TCID50 MVA-BN administered subcutaneously.

Measure
2 x 10^7 ID MVA-BN
0.1 mL of 2 x 10\^7 (50% Tissue Culture Infectious Dose (TCID50) JYNNEOS (Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN)) administered intradermally on Days 1 and 29. JYNNEOS: JYNNEOS is FDA-approved and licensed as a smallpox and monkeypox vaccine in the United States. JYNNEOS is a live vaccine produced from the strain Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN), an attenuated, non-replicating orthopoxvirus. Each 0.5 mL dose is formulated to contain 0.5 x 10\^8 to 3.95 x 10\^8 infectious units of MVA-BN live virus in 10 mM Tris (tromethamine), 140 mM sodium chloride at pH 7.7. Intradermal vaccination is administered in the volar aspect (inner side) of the forearm.

PRIMARY outcome

Timeframe: Day 43

Population: The modified intent-to-treat (mITT) population includes all participants who received at least one dose of vaccine and contributed both pre- and at least one post-vaccination venous blood sample for immunogenicity testing for which valid results were reported. Participants are analyzed according to the study product that they received.

Venous blood was collected at Study Day 43 and the serum was analyzed via the PRNT assay to determine if GMT of the intradermal regimen of 2 x 10\^7 TCID50 MVA-BN and 1 x 10\^7 TCID50 MVA- BN were non-inferior to that of the licensed regimen of 1 x 10\^8 TCID50 MVA-BN administered subcutaneously.

Population: The modified intent-to-treat (mITT) population includes all participants who received at least one dose of vaccine and contributed both pre- and at least one post-vaccination venous blood sample for immunogenicity testing for which valid results were reported. Participants are analyzed according to the study product that they received.

Blood was collected at baseline and multiple timepoints post vaccination for evaluation in a vaccinia virus Western Reserve PRNT assay. For each participant, the highest assessment post vaccination was determined as their peak response. For each arm, the geometric mean of peak responses was determined.

Population: The Safety Analysis population includes all participants who received the first study vaccination. Participants are analyzed according to the study product that they received.

Participants could voluntarily withdraw their consent for study participation for any reason at any time. Primary reason for withdrawal was recorded and early termination visits were attempted. Participants who received the first vaccination could choose to discontinue receipt of study vaccine for any reason and could choose to remain in the study (i.e., not withdraw from study). In addition, a participant could be discontinued from receipt of the second vaccination. Discontinuation from vaccination did not mean automatic withdrawal from the study, and participants were monitored for safety and immunogenicity if the participant consented.
