E.2 Objective of the trial

E.2.1

Main objective of the trial

To demonstrate the non-inferiority of the antibody (Ab) response (immunoglobulin type G [IgG]) induced by PCV21 versus 20vPCV for all serotypes included in PCV21 at 30 days after the 3rd dose (Post-dose [PD] 3), as assessed by the seroresponse rate
• To demonstrate the non-inferiority of the serotype specific IgG Ab level induced by PCV21
versus 20vPCV for all serotypes included in PCV21 at 30 days PD3, as assessed by the
geometric mean concentration (GMC)
• To demonstrate the non-inferiority of the serotype specific IgG Ab level induced by PCV21
versus 20vPCV for all serotypes included in PCV21 at 30 days after the 4th dose (PD4), as
assessed by the GMC

E.2.2

Secondary objectives of the trial

To demonstrate the non-inferiority of the immune response of the routine pediatric vaccines
administered concomitantly with PCV21 versus 20vPCV at 30 days PD3
• To demonstrate the non-inferiority of the immune response of the routine pediatric vaccines
administered concomitantly with PCV21 versus 20vPCV at 30 days PD4
• To demonstrate the superiority of the Ab response (IgG) induced by PCV21 versus 20vPCV for the additional serotype 9N and the serotype 3 at 30 days PD3, as assessed by the
seroresponse rate
• To demonstrate the superiority of the serotype specific IgG Ab level induced by PCV21 versus 20vPCV for the serotype 9N and the serotype 3 at 30 days PD3, as assessed by the GMC
• To demonstrate the superiority of the serotype specific IgG Ab level induced by PCV21 versus 20vPCV for the additional serotype 9N and the serotype 3 at 30 days PD4, as assessed by the GMC
To characterize the safety profile of PCV21 after each and any dose

- Moderate or severe acute illness/infection (according to investigator judgment) or febrile illness (temperature ≥ 38.0°C [≥ 100.4°F]) on the day of study intervention administration. A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided.
- Receipt of any vaccine in the 4 weeks preceding the study intervention administration or planned receipt of any vaccine in the 4 weeks following the study intervention administration, except for US licensed influenza vaccination, which may be received at least 2 weeks before or 2 weeks after any study vaccination. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines, as applicable per local recommendations.
- Previous vaccination against S. pneumoniae
- Previous vaccination against the following antigens: diphtheria, tetanus, pertussis, Haemophilus influenzae type b, and poliovirus
- Receipt of more than 1 dose of hepatitis B vaccine
- Receipt of immune globulins, blood or blood-derived products since birth
- Participation at the time of study enrollment (or in the 6 weeks preceding the first study intervention administration) or planned participation during the present study period in another clinical study investigating a vaccine, drug, medical device, or medical procedure
