NCT00723489

Brief Summary

The main objective of the Atopic Dermatitis and Vaccinia Immunization Network (ADVN) is to reduce the risk of the fatal reaction, eczema vaccinatum (EV), to the smallpox vaccination in those with atopic dermatitis (AD). Since vaccination with live vaccinia virus (VV) in individuals with AD increases the risk of EV, a yellow fever vaccine was chosen. The purpose of this study is to determine the immune response to a yellow fever vaccine in adults with AD.

Outcome Measures

Primary Outcomes (4)

  • Comparison of Anti-YF Antibody Levels by Measurement of Log10 Neutralization Index (LNI): YFV-17D TC- (AD) Participants Compared to YFV-17D TC- (Non-AD) Participants

    Log10 Neutralization Index (LNI) is the Log10 difference in virus titer (measurement of amount of virus) between pre-vaccination and post-vaccination. An LNI greater than or equal to 0.7 suggests that a person has active immunity against Yellow Fever virus.

    30 days after Yellow Fever (YF) immunization (Acceptable Blood Draw Range: Day 28 - Day 35 after YF immunization)

  • Comparison of Anti-YF Antibody Levels by Measurement of Log10 Neutralization Index (LNI): YFV-17D SC - (AD) Participants Compared to YFV-17D SC- (Non-AD) Participants

    Log10 Neutralization Index (LNI) is the Log10 difference in virus titer (measurement of amount of virus) between pre-vaccination and post-vaccination. An LNI greater than or equal to 0.7 suggests that a person has active immunity against Yellow Fever virus.

    30 days after YF immunization (Acceptable Blood Draw Range: Day 28 - Day 35 after Yellow Fever immunization)

  • Comparison of Anti-YF Antibody Levels by Measurement of Log10 Neutralizing Titer 50 (NT50): YFV-17D TC - (AD) Participants Compared to YFV-17D TC - (Non - AD) Participants

    Neutralization titer (NT50) is the dilution of serum (antibody) that results in a 50% reduction in the amount of virus. A higher NT50 number reflects the presence of more protective antibody levels against the Yellow Fever virus. Some studies have used an NT50 titer of 1:10 or 1:20 as the minimum level to suggest that a person has active immunity against the Yellow Fever virus.

    30 days after Yellow Fever (YF) immunization (Acceptable Blood Draw Range: Day 28 - Day 35 after YF immunization)

  • Comparison of Anti-YF Antibody Levels by Measurement of Log10 Neutralizing Titer 50 (NT50): YFV-17D SC - (AD) Participants Compared to YFV-17D SC - (Non-AD) Participants

    Neutralization titer (NT50) is the dilution of serum (antibody) that results in a 50% reduction in the amount of virus. A higher NT50 number reflects the presence of more protective antibody levels against the Yellow Fever virus. Some studies have used an NT50 titer of 1:10 or 1:20 as the minimum level to suggest that a person has active immunity against the Yellow Fever virus.

    30 days after Yellow Fever (YF) immunization (Acceptable Blood Draw Range: Day 28 - Day 35 after YF immunization)

Secondary Outcomes (6)

  • Comparison of Count of Seroconverters: YFV-17D TC- (AD) Participants Compared to YFV-17D TC - (Non-AD) Participants

    Day 0 to Day 30 (Acceptable Post-Vaccination Blood Draw Range: Day 28 - Day 35)

  • Comparison of Count of Seroconverters: YFV-17D SC - (AD) Participants Compared to YFV-17D SC - (Non-AD) Participants

    Day 0 to Day 30 (Acceptable Post-Vaccination Blood Draw Range: Day 28 - Day 35)

  • Comparison in Log10 Transformed Lymphocyte Count on Day 30 Post YF Immunization: IFN-gamma Positive, Tumor Necrosis Factor- Alpha (TNF Alpha) Positive, CD4 Positive T-cells, YFV-17D SC - (AD) Compared to YFV-17D SC - (Non- AD) Participants

    Day 30 (Day 28-35)

  • Comparison in Log10 Transformed Lymphocyte Count on Day 30 Post YF Immunization: IFN-gamma Positive, Tumor Necrosis Factor- Alpha (TNF Alpha) Positive , CD4 Positive T-cells, YFV-17D TC - (AD) Compared to YFV-17D TC - (Non-AD) Participants

    Day 30 (Day 28-35)

  • Comparison in Log10 Transformed Lymphocyte Count on Day 30 Post YF Immunization: IFN-gamma Positive, Tumor Necrosis Factor- Alpha (TNF Alpha) Positive, CD8 Positive T-cells, YFV-17D SC -(AD) Compared to YFV-17D SC - (Non-AD) Participants

Study Arms (2)

YFV-17D (Right Deltoid)

EXPERIMENTAL

Participants will be randomized within each atopic dermatitis (AD) severity subgroup or as non-atopic controls to either subcutaneous (SC) or transcutaneous (TC) vaccine administration. In this arm, participants will receive a standard vaccine dose (5.5x10\^4 Plaque Forming Units) of YFV-17D administered subcutaneously in the right deltoid and placebo vaccination transcutaneously (then covered with a semi-occlusive dressing) in the left deltoid. The site pharmacist will maintain the blind and an unblinded (i.e., masked) site coordinator will administer assigned treatment: investigators, participants and assessors remain blinded to treatment assignments throughout the duration of the trial.

Biological: Live Yellow Fever Vaccine (YFV-17D)Drug: YFV-17D Placebo

YFV-17D (Left Deltoid)

EXPERIMENTAL

Participants will be randomized within each atopic dermatitis (AD) severity subgroup or as non-atopic controls to either subcutaneous (SC) or transcutaneous (TC) vaccination. In this arm, participants will receive YFV-17D vaccination (1x10\^3 Plaque Forming Units) by transcutaneous administration (then covered with a semi-occlusive dressing to optimize YFV-17D absorption) in the left deltoid and placebo by subcutaneous administration in the right deltoid. The site pharmacist will maintain the blind and an unblinded (i.e., masked) site coordinator will administered treatment: investigators, participants and assessors remain blinded to treatment assignments throughout the duration of the trial.
