Brief summary

This study is being done to assess the possibility of the potential integration of malaria vaccine into the EPI regimen. It will evaluate whether the malaria vaccine is safe and immunogenic in infants aged 6 to 10 weeks at first dose, when co-administered with other EPI vaccine antigens. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Detailed description

Two vaccination schedules will be studied, which constitutes the two alternative three dose regimens for the malaria candidate vaccine 257049 integration into EPI. The co-administered EPI vaccines include GSK Biologicals' Tritanrix™-HepB/Hiberix™, a measles vaccine (depending on the supply availability), Aventis Pasteur's Yellow Fever vaccine Stamaril™ and GSK Biologicals' Oral Polio vaccine Polio Sabin™. Tuberculosis vaccine (Bacillus of Calmette and Guerin, BCG) will be administered according to national medical practice and will not be administered as part of this protocol, but will be documented.

Inclusion criteria

* A male or female infant between 6 and 10 weeks of age at the time of first vaccination. * Signed or thumb-printed informed consent obtained from the parent(s)/guardian(s) of the child. Where parent(s)/guardian(s) are illiterate, the consent form will be countersigned by a witness. * Subjects who have received one previous dose of OPV and BCG. * Subjects who are born after a normal gestation period (between 36 and 42 weeks).

Exclusion criteria

* Acute disease at the time of enrolment. * Serious acute or chronic illness determined by clinical or physical examination and laboratory screening tests. * Laboratory screening tests out of range, specifically: ALT and creatinine above acceptable limit; Hemoglobin, Platelet count and Total white cell count below acceptable limit. * Previous vaccination with diphtheria, tetanus, pertussis (whole-cell or acellular), Hemophilus influenzae type b or hepatitis B vaccines. * BCG administration within one week of proposed administration of a study vaccine. * OPV administration within four weeks of proposed administration of a study vaccine. * Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccine(s). * Use of any investigational or non-registered drug or vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period. * Administration of immunoglobulins, blood transfusions or other blood products since birth to the first dose of study vaccine or planned administration 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. * Simultaneous participation in any other clinical trial. * Twins (to avoid misidentification). * Maternal death. * History of allergic reactions (significant IgE-mediated events) or anaphylaxis to previous immunizations. * History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. * Any other findings that the investigator feels would increase the risk of having an adverse outcome from participation in the trial.

Pre-assignment details

The study comprised a vaccination phase (Months 0-8) and a follow-up phase (Months 8-19). The Stamaril™ vaccine was not part of the EPI Tanzanian vaccination schedule at study planning. Hence this vaccine was not administered to subjects from Tanzania.

Number of Subjects With Solicited Local Symptoms.

Assessed solicited local symptoms were pain and swelling at injection site following vaccination with each of the following study vaccines administered intramuscularly, e. a. the Tritanrix™ HepB/Hib, Rouvax™, GSK 257049 and Stamaril™ vaccines. The numbers of subjects with each of the assessed solicited local symptoms reported were tabulated for each vaccine administered, separately.

Time frame: During the 7-day (Days 0-6) follow-up period after any vaccination with the Tritanrix™ HepB/Hib, Rouvax™, GSK 257049 and Stamaril™ vaccines.

Population: The Total Vaccinated cohort included all vaccinated subjects whose symptom sheet was completed.

Number of Subjects With Unsolicited Adverse Events (AEs)

An unsolicited AE is any AE (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Unsolicited AEs were assessed following vaccination with any of the study vaccines, e. a. the Tritanrix™ HepB/Hib, Rouvax™, GSK 257049, Stamaril™ and Polio Sabin™ vaccines.

Time frame: During the 30-day (Days 0-29) follow-up period after any vaccination

Population: The analysis was performed on the Total Vaccinated cohort, which included all vaccinated subjects.

Titers for Antibodies Against Poliomyelitis Types 1, 2 and 3 (Anti-Polio 1, 2 and 3 Antibodies).

Anti-Polio 1, 2 and 3 antibody titers were expressed as geometric mean titers (GMTs). The seroprotection assay cut-off was 8.

Time frame: At Month 3

Population: The analysis was performed on the According-to-Protocol cohort for immunogenicity, which included all evaluable subjects (i.e. those meeting all eligibility criteria, complying with the procedures defined in the protocol, with no elimination criteria during the study) for whom data concerning immunogenicity endpoint measures were available.
