Clinical Trial Summary

To evaluate the immunogenicity, reactogenicity and safety of Hepatyrix when compared to the concomitant administration of Typherix and Havrix, and when compared to the administration of monovalent vaccines, Havrix or Typhim Vi. Furthermore, the study will evaluate the persistence of anti-Vi and anti-HAV antibodies up to 36 months after administration of the first dose of the study vaccine.

Description:

Compare the reactogenicity & immunogenicity of GSK Biologicals' combined Vi polysaccharide typhoid vaccine & inactivated hepatitis A vaccine, Hepatyrix, to that elicited by GSK Biologicals' hepatitis A vaccine, Havrix administered singly or concomitantly with GSK Biologicals' Vi polysaccharide vaccine, Typherix, & to that elicited by Aventis Pasteur's monovalent Vi polysaccharide vaccine, Typhim Vi, administered intramuscularly to healthy subjects aged 18-65 yrs.

Eligibility

Inclusion criteria

• Written informed consent will be obtained from the subject prior to entry into the study.

• Free of obvious health problems as established by medical history and clinical examination before entering into the study.

• Seronegative for anti-HAV antibodies.

• If the subject is female, she must be of non-childbearing potential, i.e., either surgically sterilized or one year post-menopausal; or, if of childbearing potential, she must be abstinent or have used adequate contraceptive precautions (e.g., intrauterine contraceptive device; oral contraceptives; diaphragm or condom in combination with contraceptive jelly, cream or foam; Norplant® or DepoProvera®) for 30 days prior to vaccination, have a negative pregnancy test and must agree to continue such precautions for two months after completion of the vaccination series.

• Subjects having received the study vaccines 36 months earlier.

Exclusion criteria

• Use of any investigational or non-registered drug or vaccine other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.

• Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. (For corticosteroids, this will mean prednisone, or equivalent, >or = 0.5 mg/kg/day. Inhaled and topical steroids are allowed.).

• Planned administration/Administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccine(s).

• 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.

• History of chronic alcohol consumption and/or intravenous drug abuse.

• Previous vaccination against hepatitis A.

• Previous vaccination against typhoid fever.

• History of hepatitis A.

• Previous diagnosis, confirmed by a physician, of Salmonella typhi infection.

• History of non-response to hepatitis A and or typhoid vaccine.

• Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection.

• A family history of congenital or hereditary immunodeficiency.

• History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.

• Acute disease at the time of enrolment. (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 diarrhoea, mild upper respiratory infection with or without low-grade febrile illness, i.e., axillary temperature < 99.5 °F (37.5 °C)

• Female planning to become pregnant during the primary study period (up Month 7).

• Pregnant or lactating female.

• Planned travel to areas of high endemicity for hepatitis A and/ or typhoid fever during the primary study period (up Month 7).
