Trial Outcomes & Findings for Co-Administration of AS03 Adjuvanted A/H7N9 IIV With IIV4 (NCT NCT03318315)

NCT ID: NCT03318315

Last Updated: 2020-08-06

Results Overview

Blood was collected for HAI assay at conducted with the 2017 H7N9 vaccine virus as the antigen. Each sample was tested at least twice per the laboratory's standard operating procedure, and the geometric mean of the replicate results was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 21 days after the second dose of H7N9, which is Day 43 for Group 1 and Day 64 for Group 2.

PRIMARY outcome

Timeframe: 21 days after second dose of H7N9

Population: Participants included in the modified intent-to-treat (mITT) population are those who received the first study dose have immunogenicity results at baseline and at least one timepoint post baseline. If baseline results are unavailable for an assay at baseline, the participant is not included in mITT analysis at any timepoint for that assay only.

Blood was collected for HAI assay at conducted with the 2017 H7N9 vaccine virus as the antigen. Each sample was tested at least twice per the laboratory's standard operating procedure, and the geometric mean of the replicate results was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 21 days after the second dose of H7N9, which is Day 43 for Group 1 and Day 64 for Group 2.

PRIMARY outcome

Timeframe: 21 days after second dose of H7N9

Population: Participants included in the mITT population are those who received the first study dose have immunogenicity results at baseline and at least one timepoint post baseline. If baseline results are unavailable for an assay at baseline, the participant is not included in mITT analysis at any timepoint for that assay only.

Blood was collected for the HAI assay conducted with the 2017 H7N9 vaccine virus as the antigen. Each sample was tested at least twice per the laboratory's standard operating procedure, and the geometric mean of the replicate results was calculated as that sample's result. Seroconversion was defined as HAI pre-vaccination titer \<1:10 and post-vaccination titer = / \>1:40 or pre-vaccination titer 1:10 or greater and min. 4-fold rise in post-vaccination antibody titer. 21 days after second dose of H7N9 is Day 22 for Group 1 and Day 43 for Group 2.

If baseline results are unavailable for an assay at baseline, the participant is not included in mITT analysis at any timepoint for that assay only.

Blood was collected for the serum neutralizing antibody assay at conducted with the H7N9 vaccine virus as the antigen. Each sample was tested at least twice per the laboratory's standard operating procedure, and the geometric mean of the replicate results was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results.
