Safety, Reactogenicity, and Immunogenicity of Inactivated Influenza A/H7/N7 Vaccine in Healthy Adults
Safety, Reactogenicity, and Immunogenicity of Inactivated Influenza A/H7/N7 Vaccine in Healthy Adults
The purpose of this study is to evaluate the safety, any adverse events or side effects, and
 the body's immune response to an experimental flu vaccine [Inactivated Influenza A/H7N7
 Vaccine] being given in increasing doses. Researchers will try to find the smallest dose of
 flu vaccine needed to cause antibody responses against the flu virus in both single and
 repeat doses. The study will enroll 125 healthy adults ranging in age from 18 to 40 years
 old. Subjects will be given 2 doses of the vaccine 28 days apart. Study procedures will
 include obtaining a medical history, physical exam, blood sample collections, and use of
 patient memory aids. The volunteers will be in the study for about 7 months.
This randomized, double-blinded, placebo-controlled, dose-ranging, Phase I/II, influenza
 study will compare the safety, reactogenicity, and immunogenicity of increasing doses of
 monovalent subvirion influenza A/H7N7 virus vaccine administered by intramuscular (IM)
 injection to healthy adults. A total of 125 healthy adults ranging from 18 to 40 years old
 will be enrolled at one site for this study. The subjects will be randomized to receive
 saline placebo or 7.5, 15, 45, or 90 mcg of the influenza A/H7N7 vaccine by intramuscular
 (IM) injection in an approximate 1:1:1:1:1 ratio (N=25/vaccine dose group and 25 in the
 placebo group). Subjects will receive 2 doses separated by approximately 28 days. Subjects
 will be observed in the clinic for a minimum of 30 minutes after inoculation. All subjects
 will maintain a memory aid to record oral temperature and systemic and local adverse events
 (AEs) for 7 days after each immunization. Subjects will be contacted by telephone 1-3 days
 after vaccination to assess for the occurrence of AEs, and they will return to the clinic
 between Day 8 and 12 for AE and concomitant medication assessment, a targeted physical
 examination (if indicated), and review of the memory aid. Serum for immunogenicity
 evaluations will be obtained for subjects prior to the first vaccination, at Day 28 prior to
 the second vaccination, and on Days 56 and 208. A Safety Monitoring Committee (SMC) will
 review available 7 day safety data at approximately Day 20 following the first subject
 vaccination before administering the second dose of vaccine to any subjects. The primary
 objectives of the study will be: to determine the dose-related safety of subvirion
 inactivated H7N7 vaccine in healthy adults; to determine the dose-related immunogenicity of
 subvirion inactivated H7N7 vaccine in healthy adults approximately 1 month following receipt
 of 2 doses of vaccine; and to provide information for the selection of the best dose levels
 for further studies. The secondary objective will be to evaluate the dose-related
 immunogenicity and the percent of subjects responding approximately 1 and 7 months after the
 first vaccination. The primary endpoints are: adverse event (AE) or serious adverse event
 (SAE) information (solicited in-clinic and via memory aids, concomitant medications, and
 periodic targeted physical assessment); the proportion of subjects in each dose group
 achieving a serum neutralizing antibody titer of greater than or equal to 40 against the
 influenza A/H7N7 virus 28 days after receipt of the second dose of vaccine (approximately Day
 56); geometric mean titer (GMT) and frequency of 4-fold or greater increases in neutralizing
 antibody titers in each group 1 month after receipt of each dose, and 7 months after receipt
 of the first dose of vaccine; and GMT and frequency of 4-fold or greater increases in serum
 hemagglutination inhibition (HAI) antibody titers in each group 1 month after receipt of each
 dose, and 7 months after receipt of the first dose of vaccine. Participants will be involved
 in study related procedures for approximately 7 months. This study is linked to DMID protocol
 07-0060.
Inclusion Criteria:

 -  Male or non-pregnant female (as indicated by a negative urine pregnancy test
 immediately prior to vaccine administration) between the ages of 18 and 40 years,
 inclusive.

 -  Women of childbearing potential (not surgically sterile or postmenopausal for greater
 than or equal to 1 year) who are at risk of becoming pregnant must agree to practice
 adequate contraception (i.e., barrier method, abstinence, intrauterine devices, and
 licensed hormonal methods) for the entire study period.

 -  Is in good health, as determined by vital signs (heart rate < 100 beats per minute,
 blood pressure: systolic less than or equal to 140 mm Hg and greater than or equal to
 90 mm Hg, diastolic less than or equal to 90 mm Hg; oral temperature < 100 degrees
 Fahrenheit), medical history to ensure stable* medical condition and a targeted
 physical examination based on medical history. (*A stable medical condition is defined
 as no recent change in prescription medication, dose, or frequency of medication in
 the last 3 months and health outcomes of the specific disease are considered to be
 within acceptable limits in the last 6 months. Any change that is due to change of
 health care provider, insurance company, etc, or is done for financial reasons, as
 long as in the same class of medication, will not be considered a violation of the
 inclusion criterion. Any change to prescription medication due to improvement of a
 disease outcome will not be considered a violation of the inclusion criterion.)

 -  Able to understand and comply with planned study procedures.

 -  Provide informed consent prior to initiation of any study procedures and are available
 for all study visits.

 Exclusion Criteria:

 -  Have a known allergy to eggs or other components of the vaccine (including gelatin,
 formaldehyde, octoxinol, aluminum hydroxide, and chicken protein).

 immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation
 therapy within the preceding 36 months.

 virus vaccines.
