E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that the immune response induced by 13vPnC with 2-phenoxyethanol in multidose vials (MDVs) is noninferior to the immune response induced by 13vPnC without 2-phenoxyethanol in single-dose syringes (SDSs) as measured by serotype-specific immunoglobulin G (IgG) concentrations 1 month after the infant series. |
|
E.2.2 | Secondary objectives of the trial |
To assess the immune response induced by 13vPnC with 2-phenoxyethanol in multidose vials relative to the immune response induced by 13vPnC without 2-phenoxyethanol in single-dose syringes as measured by serotype-specific opsonophagocytic activity (OPA). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Evidence of a personally signed and dated informed consent document (ICD) indicating that the subject’s parent(s)/legal guardian(s) has been informed of all pertinent aspects of the study. If the subject’s parent(s)/legal guardian(s) is illiterate they must thumbprint the ICD and it must be signed and dated by an impartial witness who was present throughout the entire informed consent process.
2. Aged 42 to 70 days at time of enrollment.
3. Available for entire study period.
4. Healthy infant as determined by medical history, physical examination, and judgment of the investigator.
5. Parent(s)/legal guardian(s) is willing and able to comply with scheduled visits and other study procedures.
6. Weight of 3.5 kg or greater at the time of enrollment. |
|
E.4 | Principal exclusion criteria |
1. Previous vaccination with licensed or investigational pneumococcal vaccine.
2. A previous anaphylactic reaction to any vaccine or vaccine-related component.
3. Contraindication to vaccination with pneumococcal conjugate vaccine.
4. Bleeding diathesis or condition associated with prolonged bleeding time that would contraindicate intramuscular injection.
5. Known or suspected immune deficiency or suppression.
6. History of culture-proven invasive disease caused by Streptococcus pneumoniae.
7. Major known congenital malformation or serious chronic disorder.
8. Significant neurological disorder or history of seizure including febrile seizure, or significant stable or evolving disorders such as cerebral palsy, encephalopathy, hydrocephalus, or other significant disorders. Does not include resolving syndromes due to birth trauma, such as Erb’s palsy.
9. Receipt of blood products or gamma-globulin since birth and until the blood draw approximately 1 month after the last dose of 13vPnC.
10. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
11. Participation in other studies within 28 days before the current study begins and/or during study participation. Participation in observational studies, and interventional studies such as those where a nasopharyngeal swab or urine sample may be collected, are permitted.
12. Subjects who are direct descendents (child or grandchild) of investigational site staff members or Pfizer employees directly involved in the conduct of the trial. |

E.5 End points |
E.5.1 | Primary end point(s) |
- The percentage of subjects achieving a serotype-specific IgG antibody concentration greater than or equal to 0.35 mcg/mL for each of the pneumococcal serotypes measured 1 month after the
infant series for each vaccine group.
- The serotype-specific IgG geometric mean concentration (GMC) for each of the pneumococcal serotypes measured 1 month after the infant series for each vaccine group (MDV group or SDS group). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
One month after completion of the infant series of injections. |
|
E.5.2 | Secondary end point(s) |
- The proportion of subjects in a subset achieving a serotype-specific OPA titer greater than or equal to the lower
limit of quantitation (LLOQ) for each of the pneumococcal serotypes measured 1 month after the infant series for each vaccine group.
- The serotype-specific OPA geometric mean titer (GMT) for each of the pneumococcal serotypes 1 month after the infant series for each vaccine group. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of the clinical phase of the study will be the last visit of the last subject. At this time, sites will be closed out, the institutional review board (IRB)/independent ethics committee (IEC) will be informed, and no further Council for International Organizations of Medical Sciences (CIOMS) reports will be sent. For other purposes, the end of the study will be the date the last serology sample is assayed. |
