Trial Outcomes & Findings for 2013/2017 H7N9 Prime-Boost Interval (NCT NCT03589807)

NCT ID: NCT03589807

Last Updated: 2021-08-02

Results Overview

Blood was collected for HAI assay which was conducted with the 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 21 days post second study vaccination (Day 43).

PRIMARY outcome

Timeframe: Day 43

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for HAI assay which was conducted with the 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 21 days post second study vaccination (Day 43).

Timeframe: Day 142

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for HAI assay which was conducted with the 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. The geometric mean titer was calculated for each study arm and stratum from the available results at 21 days post study vaccination (Day 142).

Timeframe: Day 43

Population: The modified intent-to-treat (mITT) population includes all participants who received at least one study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for the HAI assay 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 percentage of participants with HAI titer \>= 1:40 was calculated for each study arm from the available results at 21 days post second study vaccination (Day 43).

Timeframe: Day 43

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for Neut antibody assays for which valid results were reported.

Blood was collected for the Neutralizing assay 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 percentage of participants with Neut titer \>= 1:40 was calculated for each study arm from the available results at 21 days post second study vaccination (Day 43).

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for HAI assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 21 days post first study vaccination (Day 22).

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for Neut antibody assays for which valid results were reported.

Blood was collected for Neut assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. The geometric mean titer was calculated for each study arm from the available results at 180 days post second study vaccination (Day 202).

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for HAI assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen 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 and minimum 4-fold rise in post-vaccination antibody titer. 21 days after first study vaccination is Day 22.

SECONDARY outcome

Timeframe: Day 202

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for HAI antibody assays for which valid results were reported.

Blood was collected for HAI assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen 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 and minimum 4-fold rise in post-vaccination antibody titer. 180 days after second study vaccination is Day 202.

Population: The modified intent-to-treat (mITT) population includes all participants who received study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for Neut antibody assays for which valid results were reported.

Blood was collected for Neutralizing assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result. Seroconversion was defined as Neut pre-vaccination titer \<1:10 and post-vaccination titer \>= 1:40 or pre-vaccination titer \>= 1:10 and minimum 4-fold rise in post-vaccination antibody titer. 180 days after second study vaccination is Day 301.

Timeframe: Day 22

Population: The modified intent-to-treat (mITT) population includes all participants who received at least one study vaccination and contributed both pre- and at least one post-study vaccination venous blood samples for Neut antibody assays for which valid results were reported.

Blood was collected for Neut assay which was conducted with the 2013 and 2017 H7N9 vaccine viruses as the antigens. Each sample was tested at least twice per antigen per the laboratory's standard operating procedure, and the geometric mean of the replicate results of each antigen was calculated as that sample's result The percentage of participants with Neut titer \>= 1:40 was calculated for each study arm from the available results at 21 days post first study vaccination (Day 22).
