NCT00439335

Brief Summary

This study will compare the influenza A/H5N1 virus vaccine given by injection in the muscle versus injection in the skin in healthy adults. The study will look at the safety of the injections, how the body reacts, and what the body's immune response does when the vaccine is given in the muscle versus in the skin. The study will look at 226 healthy volunteers, ages 18-49 years old. Study procedures will include getting 2 doses of vaccine 28 days apart, physical exams, follow-up clinic visits to check the places on the body where each vaccine was given, and blood sample collections. Volunteers will complete a memory aid by writing down temperatures and health changes for 7 days after each vaccination. Volunteers will be involved in the study for up to 241 days.

Outcome Measures

Primary Outcomes (5)

  • Number of Participants Achieving a 4-fold or Greater Increase in HAI Antibody Titers After Dose 2

    Number of participants in each vaccine group achieving a 4-fold or greater increase in serum hemagglutination inhibition (HAI) antibody titers against influenza A/H5N1 virus 28 days after receipt of the second dose of vaccine

    Approximately Day 56.

  • Number of Participants Spontaneously Reporting Any Serious Adverse Event.

    Any untoward medical occurrence that resulted in death, persistent/significant disability/incapacity, required in-patient hospitalization or prolongation thereof, was life threatening or a congenital anomaly/birth defect in offspring of a study subject; or may have jeopardized the participant or required intervention to prevent one of the outcomes.

    Through Day 208.

  • Occurrence of Unsolicited Symptoms During a 28-day Surveillance Period Following Vaccinations at Days 0 and 28.

    The number of participants spontaneously reporting any symptom (defined as any Adverse Event considered associated with the product) within 28 days of vaccination. Participants are counted only once but may have experienced events on multiple occasions.

    Through approximately Day 56

  • Occurrence of Solicited Systemic Symptoms During a 7-day Surveillance Period (Systematically Collected) Following Vaccinations at Days 0 and 28.

    The number of participants reporting fever, feverishness, malaise, myalgia, headache and nausea. Participants are counted only once for each symptom but may have experienced symptoms on multiple occasions.

    7 days after each vaccination

  • Occurrence of Solicited Local Symptoms During a 7-day Surveillance Period (Systematically Collected) Following Vaccinations at Days 0 and 28.

    The number of participants reporting pain, tenderness, itching, induration, erythema, and pigmentation. Participants are counted only once for each symptom but may have experienced symptoms on multiple occasions.

    7 days after each vaccination

Secondary Outcomes (8)

  • HAI Geometric Mean Titer (GMT) After Dose 2

    Approximately Day 56.

  • Number of Participants Achieving a HAI Titer of Greater Than or Equal to 40 After Dose 2

    Approximately Day 56

  • Number of Participants Achieving a 4-fold or Greater Increase in HAI Antibody Titers After Dose 1.

    Approximately Day 28

  • HAI GMT After Dose 1

    Approximately Day 28

  • Number of Participants Achieving a Serum HAI Titer of Greater Than or Equal to 40 After Dose 1.

    Approximately Day 28

  • +3 more secondary outcomes

Study Arms (2)

H5 HA IM

EXPERIMENTAL

Vaccine group H5 HA IM: the subject will receive 0.1 mL of H5 HA by the IM route in one arm and 0.1 mL of saline placebo by the ID route in the other arm.

Biological: Inactivated Influenza A Vaccine A/H5N1Drug: Placebo (ID)

H5 HA ID

EXPERIMENTAL

Vaccine group H5 HA ID: the subject will receive 0.1 mL of H5 HA by the ID route in one arm and 0.1 mL of saline placebo by the IM route in the other arm.

Biological: Inactivated Influenza A Vaccine A/H5N1Drug: Placebo (IM)

Interventions

Inactivated influenza A/H5N1 vaccine formulated to a concentration of HA greater than or equal to 300 mcg/mL administered via intramuscular (IM) injection. Vaccine will be administered to each subject at Days 0 and 28.
