Trial Outcomes & Findings for Atopic Dermatitis Research Network (ADRN) Influenza Vaccine Study (NCT NCT01737710)

NCT ID: NCT01737710

Last Updated: 2017-03-29

Results Overview

The difference in the percent of participants that achieved seroprotection against influenza B at Day 28 between non-AD and moderate to severe AD participants, following a single dose (0.1mL) of the seasonal 2012 - 2013 Fluzone Intradermal vaccine. Seroprotection is defined as having a serum hemagglutination-inhibition (HAI) antibody titer of 1:40 or greater, which represents a sufficient antibody amount to avoid disease in half of the individuals infected with influenza B. Participants who achieved seroprotection prior to vaccination were excluded from the analysis. The goal was to examine whether there was a difference between the two groups in the percent of participants who achieved seroprotection at Day 28 who were not seroprotected prior to vaccination.

PRIMARY outcome

The difference in the percent of participants that achieved seroprotection against influenza B at Day 28 between non-AD and moderate to severe AD participants, following a single dose (0.1mL) of the seasonal 2012 - 2013 Fluzone Intradermal vaccine. Seroprotection is defined as having a serum hemagglutination-inhibition (HAI) antibody titer of 1:40 or greater, which represents a sufficient antibody amount to avoid disease in half of the individuals infected with influenza B. Participants who achieved seroprotection prior to vaccination were excluded from the analysis.

SECONDARY outcome

Timeframe: Day 28 post vaccination

Population: Subset of the per protocol population that were not seroprotected against influenza B at baseline. These participants received a full dose of vaccine, provided blood samples on Day 0 and Day 28, and had no major protocol deviations.

The fold-difference (defined as a ratio to describe the change from baseline to Day 28) in geometric mean serum HAI antibody titers against influenza B between non-AD and moderate to severe AD participants, following a single dose of the seasonal 2012-2013 Fluzone Intradermal vaccine. A fold-difference of greater than 1 indicated an increase in HAI antibody titers against influenza B as a result of vaccination; therefore, higher numbers indicate a greater probability of avoiding disease if infected with influenza B. Participants who achieved seroprotection (which is defined as having a sufficient antibody amount to avoid disease in half of the individuals infected with influenza B) prior to vaccination were excluded from the analysis.

The difference in the percentage of participants that achieved seroconversion at Day 28 between non-AD and moderate to severe AD participants, following a single dose (0.1mL) of the seasonal 2012 - 2013 Fluzone Intradermal vaccine. Seroconversion is defined as a 4-fold or greater increase in serum hemagglutination-inhibition \[HAI\] antibody titers against influenza B compared to baseline values, which represents the minimum intended effect of vaccination. Participants who achieved seroprotection, defined as having a sufficient antibody amount to avoid disease in half of the individuals infected with influenza B, prior to vaccination were excluded from the analysis. The goal was to examine whether there was a difference between the two groups in the percentage of participants who achieved seroconversion at Day 28 who were not seroprotected prior to vaccination.

Timeframe: Day 28 Post Vaccination

Population: Subset of the per protocol population that were not seroprotected against influenza H1N1 at baseline. These participants received a full dose of vaccine, provided blood samples on Day 0 and Day 28, and had no major protocol deviations.

The difference in the percentage of participants that achieved seroconversion at Day 28 between non-AD and moderate to severe AD participants, following a single dose (0.1mL) of the seasonal 2012 - 2013 Fluzone Intradermal vaccine. Seroconversion is defined as a 4-fold or greater increase in serum hemagglutination-inhibition \[HAI\] antibody titers against influenza H1N1 compared to baseline values, which represents the minimum intended effect of vaccination. Participants who achieved seroprotection, defined as having a sufficient antibody amount to avoid disease in half of the individuals infected with influenza H1N1, prior to vaccination were excluded from the analysis. The goal was to examine whether there was a difference between the two groups in the percentage of participants who achieved seroconversion at Day 28 who were not seroprotected prior to vaccination.
