Eligibility Criteria

18 Years - 50 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • • A male or non-lactating female 18 to 50 years of age (inclusive) at the time of screening

    • Free of significant health problems as established by medical history and clinical examination before entering into the study
    • Available to participate for duration of study (approximately seven months)

If the subject is female, she must be of non-childbearing potential (either surgically sterilized or one year post-menopausal) or, if of childbearing potential, she must have a negative pregnancy test at the time of vaccination, be capable of preventing pregnancy for at least one month prior to determination of eligibility (to include abstinence or contraceptives (for example intrauterine contraceptive device; oral contraceptives; Norplant® or Depo-Provera® ), and must agree to continue such precautions for two months after completion of the vaccination series.

Written informed consent must be obtained from the subject before screening procedures.

Exclusion Criteria:

    • Prior receipt of a vaccine containing either QS-21, MPL or AS02A or AS01B

    Outcomes

    Primary Outcome Measures

    Number of Participants With Solicited Adverse Events With Each Vaccination by Grade
    Vaccinations were given at 0-, 1-, 2-month interval, occurrence and intensity of solicited symptoms on day of vaccination (Day 0) and Days 1-7 after each vaccination Grade 1 = Mild Grade 2 = Moderate Grade 3 = Severe
    Number of Subjects With Unsolicited Adverse Events at Specified Grades
    Vaccinations were given at 0-, 1-, 2-month interval, number of subjects reporting unsolicited symptoms at specified grades over a 30-day follow-up period (day of vaccination and 29 subsequent days) after each vaccination Grade 1 = Mild Grade 2 = Moderate Grade 3 = Severe
    Number of Subjects With the Occurrence of Serious Adverse Events
    Vaccinations were given at 0-, 1-, 2-month interval, number of subjects with the occurrence of serious adverse events at days 0-7 post vaccination

    Secondary Outcome Measures

    Antibody Titers Per Subject by Enzyme Linked Immunosorbent Assay in 50 µg Dose Group
    Antibody concentrations will be presented by reporting the summarized Geometric Mean Titer (GMT) values with 95% Confidence Interval (CI) (not presented in results), at each time point at which blood samples are taken for serology. Peak responses (Day 70) will be compared by Student's T test on data normalized by log transformation to ascertain presence or absence of significant dose response difference. GMTs are presented without CI data.

    5. Study Description

    Brief Summary
    The purpose of this study is to determine whether an investigational malaria vaccine is safe and induces an immune response against malaria when tested in adults living in the United States.
    Detailed Description
    Study is to evaluate the safety, reactogenicity, and immunogenicity fo the candidate Plasmodium falciparum malaria protein 10 (FMP010). Malaria-experienced adults will be enrolled and randomized into 2 groups. Subjects will receive full dose FMP010 antigen (approximately 50 μg) in 0.5 mL AS01B adjuvant or licensed rabies vaccine Rabipur (by Novartis) supplied in single dose vials containing lyophilized antigen with 1.0 mL of diluent (sterile water) for injection.
