E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the immune responses following vaccination with a booster dose of the 10Pn-PD-DiT vaccine administered at either 9-12 or 15-18 months of age in children previously vaccinated with the 10Pn-PD-DiT vaccine in study 10PN-PD-DIT-037 (111188) according to a 3-dose primary vaccination at 6, 10 and 14 weeks of age. |
|
E.2.2 | Secondary objectives of the trial |
• To assess, prior to booster vaccination, antibody persistence following primary vaccination with 10Pn-PD-DiT vaccine.
• To assess immunogenicity of 10Pn-PD-DiT vaccine following 2-dose primary vaccination and booster vaccination administered as a catch-up immunization according to a 2+1 vaccination schedule in unprimed children during the second year of life.
• To assess safety and reactogenicity of 10Pn-PD-DiT vaccine when administered as a catch-up immunization according to a 2+1 vaccination schedule in unprimed children during the second year of life.
• To assess safety and reactogenicity of a booster dose of 10Pn-PD-DiT vaccine when administered at either 9-18 or 15-18 months of age in children primed with 10Pn-PD-DiT vaccine in study 10PN-PD-DIT-037 (111188) according to a 3-dose primary vaccination at 6, 10 and 14 weeks of age.
• To assess antibody persistence following booster vaccination with 10Pn-PD-DiT vaccine up to approximately 24 months of age in the primed groups. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Male or female subjects for whom the investigator believes that their parent(s)/ guardian(s) can and will comply with the requirements of the protocol.
•For primed subjects:
-Completion of the full vaccination course in study 10PN-PD-DIT-037 (111188).
-9-18 months at the time of randomization.
-9-18 months of age at the time of booster vaccination for the Pn-Pn9 group.
-15-18 months of age at the time of booster vaccination for the Pn-Pn15 group.
• For unprimed subjects:
-Enrolled in study 10PN-PD-DIT-037 (111188).
-12-18 months of age at the time of first vaccination in the present study.
• Written, signed or thumb-printed informed consent obtained from the parent(s)/guardian(s) of the child/ward. Where parent(s)/guardian(s) are illiterate, the consent form will be countersigned by a witness.
• Healthy subjects as established by medical history and clinical examination before entering into the study. |
|
E.4 | Principal exclusion criteria |
• Use of any investigational or non-registered product within 30 days preceding the vaccination, or planned use during the study period.
• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product.
• Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to vaccination.
• Administration of any pneumococcal vaccine since the end of study 10PN-PD-DIT-037 (111188).
• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
• History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
• Major congenital defects or serious chronic illness.
• History of any neurologic disorders or seizures.
• Acute disease at the time of enrolment.
• Administration of immunoglobulins and/or any blood products within three months preceding the vaccination or planned administration during the study period. |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
