About
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.
Full 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.

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 any investigational malaria vaccine
Prior receipt of a vaccine containing either QS-21, MPL or AS02A or AS01B
Use of any investigational or non-registered drug or vaccine other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period
Administration of chronic (defined as more than 14 days) immunosuppressants or other immune modifying drugs within six months of vaccination. For corticosteroids, this is defined as prednisone, or equivalent, 0.5 mg/kg/day. Inhaled and topical steroids are allowed.
Planned administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of the study vaccine.
Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection
A family history of congenital or hereditary immunodeficiency
Chronic or active neurologic disease including seizure disorder
History of splenectomy
Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or abnormal baseline laboratory screening tests
Acute disease at the time of enrollment (acute disease is defined as the presence of a moderate or severe illness with or without fever). All vaccines can be administered to persons with a minor illness, such as diarrhea or mild upper respiratory infection without fever, i.e. Oral temperature < 37.5°C.
Hepatomegaly, right upper quadrant abdominal pain or tenderness
Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration during the study period
Pregnant or lactating female
Suspected or known current alcohol abuse/drug abuse as obtained by history and physical examination
Female who is willing or intends to become pregnant during the study
Any history of allergic reaction or anaphylaxis to previous vaccination
Unwilling to allow blood samples to be stored for future use
Inability to make follow up visits
Allergy to kanamycin, nickel, or imidazole
Any other significant finding that in the opinion of the investigator would increase the risk of having an adverse outcome from participating in this study
Previous allergy to Rabies Vaccine
Allergy to chicken and chicken products
