NCT Number: NCT01262872
This study will assess the impact on nasopharyngeal carriage, safety and immunogenicity of GSK Biologicals' pneumococcal vaccine 2189242A given as a 3-dose vaccination course and co-administered with other routine paediatric vaccines in infants in The Gambia. Two formulations containing different doses of pneumococcal antigen and two different schedules will be tested in infants.

Banjul, The Gambia
There will be two cohorts in the study: Cohort 1 (children aged 2-4 years) and Cohort 2 (infants aged 8-10 weeks), and two steps in the study, Step 1 and Step 2. Step 1 will consist in a safety evaluation of the GSK Biologicals' pneumococcal vaccine 2189242A (GSK 2189242A or 10PP vaccine). Before evaluating the two formulations of the 10PP vaccine in infants (Cohort 2), safety and reactogenicity of the highest dose formulation of this vaccine will be evaluated in children (Cohort 1). Prevnar 13™ will be used as a control. In the second step of the study, Step 2, two investigational formulations of the 10PP vaccine will be tested in infants (Cohort 2) as regards immunogenicity, reactogenicity and safety. Both formulations of the 10PP vaccine will be evaluated according to the Expanded Programme on Immunization (EPI) schedule i.e. a 2, 3, 4 months vaccination schedule, using licensed Synflorix™ and Prevnar 13™ vaccines as comparators. The higher dose (HD) formulation of the 10PP vaccine will be also evaluated according to the 2, 4, 9 months vaccination schedule using licensed Synflorix™ vaccine as comparator. The study in infants will also assess the immune responses to routine vaccines when co-administered with the candidate pneumococcal vaccine, using licensed Synflorix™ and Prevnar 13™ vaccines as comparators.

An unsolicited AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. Any = Occurrence of AE, regardless of intensity or relationship to vaccination. Grade 3 = Occurrence of AE which prevented normal activities. Related = Occurrence of AE assessed by the investigator as causally related to vaccination. Primary results correspond to results for occurrences of Grade 3 unsolicited AE(s) assessed as related to vaccination. This outcome concerns subjects enrolled in Cohort 1/Step 1.

An unsolicited AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. Any = Occurrence of an unsolicited AE, regardless of intensity or relationship to vaccination. This outcome concerns Step 2/Cohort 2 subjects receiving the 3+0 Schedule.

An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. Any = Occurrence of an unsolicited AE, regardless of intensity or relationship to vaccination. This outcome concerns Step 2/Cohort 2 subjects receiving the 2+1 Schedule.
Time frame: From Day 0 to Month 10
SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity. These should also be considered serious: invasive or malignant cancers, intensive treatment in an emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation. Any = Occurrence of an SAE, regardless of relationship to vaccination. This outcome concerns subjects enrolled in Cohort 2/Step 2 receiving the 3+0 Schedule.

This outcome concerns subjects enrolled in Cohort 2/Step 2 receiving the 2+1 Schedule.
Time frame: At Month 0 (Pre-vaccination), Month 3 (1 month [m] post-dose [P] III-3+0 schedule or PII-2+1 schedule), Month 7 (5 m PIII - 3+0 schedule or PII-2+1 schedule) or at Month 10 (8 m PIII - 3+0 schedule or 3 m post-booster-2+1 schedule)
Isolates from the Prev13_3D group were not selected. Samples were distributed evenly in the 5 groups and across time points: 10 isolates from pre-vaccination, 20 at Month 3, 20 at Month 7 and 20 at Month 10. Only samples displaying non-vaccine and non-vaccine related serotypes (all serotypes except serotypes 1, 4, 5 and 14 and serotypes belonging to the serogroups 6, 7, 9, 18, 19 and 23) were selected in systematic (equal number across groups) but non-random manner. Samples were described as follows: samples with gene detected (Positive isolates) with sequenced protein, number of protein Variants, number of isolates with Variant 1 (100% identity with vaccine sequence).
Time frame: At Month 0 (Pre-vaccination), Month 3 (1 month [m] post-dose [P] III-3+0 schedule or PII-2+1 schedule), Month 7 (5 m PIII - 3+0 schedule or PII-2+1 schedule) or at Month 10 (8 m PIII - 3+0 schedule or 3 m post-booster-2+1 schedule)

Overall, 18 different Ply protein sequences were identified: 5 protein variants previously described (e.g. variants 1, 2, 7, 11 and 15), plus 13 new protein variants which are referred to as variants GSK21 to GSK33. The number of Amino Acids (AA) mutation versus vaccine sequence has been specified for each Ply variant. The samples without gene detected were considered as negative for Ply (Ply negative).
Time frame: At Month 0 (Pre-vaccination), Month 3 (1 month [m] post-dose [P] III-3+0 schedule or PII-2+1 schedule), Month 7 (5 m PIII - 3+0 schedule or PII-2+1 schedule) and Month 10 (8 m PIII - 3+0 schedule or 3 m post-booster-2+1 schedule)
Protein sequence identity was compared to vaccine sequence. Mean and median was calculated and expressed as percentage.
Time frame: At Month 0 (Pre-vaccination), Month 3 (1 month [m] post-dose [P] III-3+0 schedule or PII-2+1 schedule), Month 7 (5 m PIII - 3+0 schedule or PII-2+1 schedule) and Month 10 (8 m PIII - 3+0 schedule or 3 m post-booster-2+1 schedule)
Because of high variants heterogeneity in each group (no major variant), the impact of vaccination on variant prevalence was not analysed. PhtD sequences were detected in some samples but no consensus sequence could be obtained they were defined as mixed sequences (Mix). The samples without gene detected were considered as negative for PhtD (PhtD negative).
Time frame: At Month 0 (Pre-vaccination), Month 3 (1 month [m] post-dose [P] III-3+0 schedule or PII-2+1 schedule), Month 7 (5 m PIII - 3+0 schedule or PII-2+1 schedule) and Month 10 (8 m PIII - 3+0 schedule or 3 m post-booster-2+1 schedule)
Protein sequence identity was compared to vaccine sequence. Mean and median was calculated and expressed as percentage.
