Clinical Trial Summary

The purpose of this study is to compare the immediate and long term (up to 5 years) immunogenicity and safety of GSK Biologicals' MenACWY-TT vaccine when given as a single dose or as 2 doses to toddlers aged 12 to 14 months. Also, this study will also assess if co-administration of GSK Biologicals' MenACWY-TT with the booster dose of Pfizer's Prevenar 13 adversely impacts the immunogenicity of either of the vaccines.


Description:

The Medicines Control Council (MCC) authorities requested that subjects be screened for HIV testing prior to study enrolment in South Africa to ensure that only HIV negative participants are enrolled. As such, HIV rapid test was added at Visit 1 only for subjects in South Africa. Subjects previously screened HIV positive will be excluded.

Secondary Geometric Mean Titers (GMTs) With OPA for Each of the Anti-pneumococcal Serotypes at 1 Month After Administration of Prevnar 13 in the Co-ad and PCV-13 Groups OPA titers were determined for anti-pneumococcal serotypes: OPSONO-1, OPSONO-3, OPSONO-4, OPSONO-5, OPSONO-6A, OPSONO-6B, OPSONO-7F, OPSONO-9V, OPSONO-14, OPSONO-18C, OPSONO-19A, OPSONO-19F and OPSONO-23F. OPA titers are expressed as 1/dilution. ATP cohort for immunogenicity post dose 1 included all evaluable participants who met eligibility criteria, complied with the procedures defined in the protocol and with no elimination criteria during the study from the ATP cohort for safety, received all study vaccines at Month 0, had assay results available for antibodies against at least one study vaccine antigen component at Visit 2, those with available blood sample at Visit 2 for PCV13 group. 1 month after administration of Prevnar 13 (i.e. at Month 1)
Secondary Number of Participants With Solicited Local Reactions Within 4 Days Post Each Vaccination Solicited local reactions included pain, redness and swelling. Here, '0' in the number analyzed field signifies that no vaccine was administered in the specified group for the specified category. Within 4 days post each vaccination (vaccination 1 [at Month 0] and vaccination 2 [at Month 2])
Secondary Number of Participants With Solicited General Reactions Within 4 Days Post Each Vaccination Solicited general reactions included drowsiness, irritability/fussiness, loss of appetite and fever. Here, '0' in the number analyzed field signifies that no vaccine was administered in the specified group for the specified category. Post dose 1 for ACWY1d and Co-ad group included reactions occurred after dosing of both MenACWY-TT and Prevenar 13 for Co-ad group and data was collected and summarized collectively. Within 4 days post each vaccination (vaccination 1 [Dose 1] and vaccination 2 [Dose 2])
Secondary Number of Participants With Unsolicited Adverse Events Within 31 Days Post Any Study Vaccination, Classified According to Medical Dictionary for Regulatory Activities (MedDRA) An adverse event was any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An unsolicited adverse event was an observed adverse event that did not fulfill the conditions prelisted in the case report book (CRB) in terms of symptom and/or onset post-vaccination. Within 31 days post any vaccination
Secondary Number of Participants With Serious Adverse Events From Month 0 to Month 9 An adverse event was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event was any untoward medical occurrence at any dose that: resulted in death, was life threatening (immediate risk of death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions), resulted in congenital anomaly/birth defect. Month 0 to Month 9
Secondary Number of Participants With Serious Adverse Events Related to Study Vaccination From First Dose of Study Drug up to End of Study An adverse event was any untoward medical occurrence in a participant who received study drug. Serious adverse event was any untoward medical occurrence at any dose that: resulted in death, was life threatening (immediate risk of death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions), resulted in congenital anomaly/birth defect. Related adverse events were those adverse events who were related to the vaccination as judged by the investigator. Baseline up to end of study (up to 5 years)
Secondary Number of Participants With Any New Onset of Chronic Illnesses (NOCIs) From Month 0 to Month 9 New onset chronic illness included autoimmune disorders, asthma, type I diabetes and allergies. Month 0 to Month 9
