Safety and Immunogenicity of a Pneumococcal Conjugate Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Toddlers and Infants

Primary objectives:

  • To assess the safety profile of each SP0202 formulation and Prevnar 13 in toddlers and infants (after each and any injection).
  • To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4)
  • To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in infants (Groups 5-8)
  • To assess the immune response (serotype specific IgG concentration) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in infants (Groups 5-8)

Secondary objectives:

  • To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of one dose in toddlers (Groups 1-4)
  • To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after the administration of 3 doses in a subset of infants (Groups 5-8)
  • To assess the immune response (serotype specific OPA titer) of the SP0202 formulations and Prevnar 13 1 month after administration of a 4-dose schedule in a subset of infants (Groups 5-8)
  • In toddlers: to describe the Ab responses against Pentacel antigens before and 1 month following injection of Pentacel
  • In infants: to describe the Ab responses against antigens of the routine pediatric vaccines (Pentacel, RotaTeq, ENGERIX-B, M-M-RII, and VARIVAX) when administered concomitantly with either SP0202 or Prevnar 13 (at pre-Dose 1 (as applicable) for RotaTeq, Diphteria, Tetanus and Pertussis antigens; at PD3 for ENGERIX-B, RotaTeq, and Pentacel; at PD4 for M-M-RII and VARIVAX])

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Immediate Adverse Events (AEs)
Time Frame: Up to 30 minutes after each vaccination
An AE was any untoward medical occurrence in a participant or in a clinical investigation participant administered a medicinal product and which did not necessarily have a causal relationship with this treatment. Immediate events were recorded to capture medically relevant unsolicited systemic AEs (including those related to the product administered) that occurred within the first 30 minutes after vaccination. An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the case report book (CRB) in terms of diagnosis and/or onset window post-vaccination and included both serious adverse events (SAEs) and non-serious unsolicited AEs.
Up to 30 minutes after each vaccination
Number of Participants With Solicited Injection Site Reactions
Time Frame: Up to 7 days after each vaccination
A solicited reaction was an "expected" adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) prelisted in the protocol and CRB and were considered to be related to the product administered. An injection site reaction was an adverse reaction at and around the injection site which were commonly inflammatory reactions. Solicited injection site reactions included tenderness, erythema and swelling around the injection site and were planned to be collected and reported for SP0202/Prevnar 13 for both toddlers and infants.
Up to 7 days after each vaccination
Number of Participants With Solicited Systemic Reactions
Time Frame: Up to 7 days after each vaccination
A solicited reaction was an "expected" adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) pre-listed in the protocol and CRB and considered as related to the product administered. Solicited systemic reactions included fever, vomiting, abnormal crying, drowsiness, appetite loss, and irritability. Reported AEs for each arm were presented as pre-specified in protocol.
Up to 7 days after each vaccination
Number of Participants With Unsolicited AEs
Time Frame: Up to 30 days after each vaccination
An AE was any untoward medical occurrence in a clinical investigation participant administered a medicinal product, and which did not necessarily have a causal relationship with this treatment. An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the CRB in terms of diagnosis and/or onset window post-vaccination. Unsolicited AEs included both SAEs and non-serious unsolicited AEs. Reported AEs for each arm were presented as pre-specified in protocol.
Up to 30 days after each vaccination
Number of Participants With SAEs and Adverse Event of Special Interest (AESIs)
Time Frame: From first dose vaccine administration (Day 1) until 6 months after the last dose administration, 490 days
An SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event. An AESI (serious or non-serious) was defined as one of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and rapid communication by the Investigator to the Sponsor was appropriate. The following AE were captured as AESI throughout the study: Anaphylaxis defined as per the Brighton collaboration case definition, convulsions including febrile convulsions, hypotonic-hyporesponsive episode and apnea. Reported AEs for each arm were presented as pre-specified in protocol.
From first dose vaccine administration (Day 1) until 6 months after the last dose administration, 490 days
For Toddlers: Serotype Specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) for Each Pneumococcal Serotype at 30 Days Post-Dose
Time Frame: Day 30
The GMCs for serotype specific pneumococcal IgG antibodies were measured using pneumococcal capsular polysaccharide-electro-chemiluminescent assay (PnPS-ECL), a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.
Day 30
For Infants: Percentage of Participants With Serotype Specific IgG Concentration >=0.35 mcg/mL 30 Days Post-Dose 3
Time Frame: Day 150
Percentage of infants with serotype specific IgG concentration >=0.35 mcg/mL for each pneumococcal serotype included in the SP0202 formulations were measured using ECL, a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.
Day 150
For Infants: Serotype Specific IgG GMCs for Each Pneumococcal Serotype at 30 Days Post-Dose 3
Time Frame: Day 150
The GMCs for serotype-specific pneumococcal IgG antibodies were measured using PnPS-ECL, a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.
Day 150
For Infants: Serotype Specific IgG GMCs for Each Pneumococcal Serotype at 30 Days Post-Dose 4
Time Frame: Day 330
The GMCs for serotype specific pneumococcal IgG antibodies were measured using PnPS-ECL, a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.

Anti-diphtheria and anti-tetanus concentrations were measured using electro-chemiluminescence assay (ECL) and anti-PRP concentrations were measured using a Farr-type radioimmunoassay.
Day 150
For Infants: Percentage of Participants With Antibody Responses to Poliovirus 1, 2 and 3 30 Days Post-Dose 3
Time Frame: Day 150
Anti-poliovirus types 1, 2, and 3 were measured by neutralization assay. Response was defined as a titer >=8.
Day 150
For Infants: GMCs of Antibodies to Pertussis Antigens 30 Days Post-Dose 3
Time Frame: Day 150
Serum samples were collected for analysis by ECL to determine the GMC of antibodies to the following Pertussis antigens: Pertussis toxoid/toxin, Filamentous hemagglutinin, Pertactin and Fimbriae types 2 and 3.
Day 150
For Infants: Percentage of Participants With Antibody Responses to Hepatitis-B Antigens 30 Days Post-Dose 3
Time Frame: Day 150
Anti-Hepatitis B antibodies were measured by the commercially available VITROS ECi/ECiQ immunodiagnostic system using chemiluminescence detection technology. The VITROS ECi immunodiagnostic system uses an antibody mediated antigen sandwich formation to detect the presence of anti-hepatitis B surface antigen total immunoglobulin in human serum. The threshold presented is >=10 milli international units (mIU).
Day 150
For Infants: Percentage of Participants With Antibody Responses to M-MRII and Varivax Antigens 30 Days Post-Dose 4
Time Frame: Day 330
Anti-measles antibodies were determined by bulk measles IgG enzyme immunoassay (EIA); anti-mumps antibodies by ELISA, anti-rubella antibodies by bulk rubella IgG EIA and anti-varicella antibodies were determined by glycoprotein ELISA to detect total IgG antibody to respective virus before and after vaccination with a virus-containing vaccine. Percentage of participants with anti-measles antibody concentrations >=255 mIU/mL, anti-mumps antibody concentrations: >=10 antibody units/mL, anti-rubella antibody concentrations >=10 IU/mL and anti-varicella concentrations >=5 units/mL is reported in this outcome measure.
