A Phase 3 Study to Evaluate the Immunogenicity and Safety of Walvax's PCV13-TT as Compared to Pfizer's PCV13
A Phase 3, Randomized, Blinded, Active-controlled Study to Evaluate the Immunogenicity and Safety of Walvax's 13-valent Pneumococcal Polysaccharide Conjugate Vaccine (PCV13-TT) as Compared to Pfizer's 13-Valent Pneumococcal Conjugate Vaccine (PCV13) Co-administered With EPI Vaccines at 2, 4, and 12-15 Months of Age, to Healthy Infants in Indonesia

Detailed Description
H0: the immune responses elicited by PCV13-TT are inferior to those elicited by PCV13
HA: the immune responses elicited by PCV13-TT are non-inferior to those elicited by PCV13.
Non-inferiority of the immune responses elicited by PCV13-TT will be declared if both of the following criteria are met: (1) the lower limit of the 2-sided 95% CI of the difference (PCV13-TT-PCV13) in proportions of responders who achieving the threshold of 0.35 µg/ml is >-10%; and (2) the lower limit of the 2-sided 95% CI of the GMC ratio (PCV13-TT/PCV13) is >0.5. Thus, the familywise type I error will not be inflated.

Accepts Healthy Volunteers
Description
Inclusion Criteria:
Infants must meet ALL the following inclusion criteria for enrollment in the study, at the time of the screening:
- Healthy infants based on medical history and clinical assessment.
- Age of 6-8 weeks at enrolment. Infants will be eligible since the day they reach 6 weeks of age and until 8 weeks of age included.
- Body weight at enrollment ≥3.5 kg.
- Infant's parent(s) or legal guardian(s) must be able and willing to provide voluntary written/thumb-printed informed consent for the infant to participate in the study.
- Infant's parent(s) or legal guardian(s) must be able to comprehend and comply with study requirements and procedures and must be willing and able to return or make themselves available for all scheduled follow-up visits.
- Infant's parents must have a readily identifiable place of residence in the study area, be available for the duration of trial participation, and have means of telephone contact.
Exclusion Criteria:
The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study:
- Use of any investigational medicinal product prior to randomization or planned use of such a product during the period of study participation.
- History of S. pneumoniae infection as confirmed by medical enquiry or as confirmed by laboratory testing if available.
- Participant has fever (axillary temperature ≥ 37.5℃) within 24 hours prior to the 1st dose of vaccination; (If the subject does not meet the criteria, the visit may be rescheduled when the criteria are met.)

- History of allergic disease or history of a serious reaction to any prior vaccination or known hypersensitivity to any component of the 2 study vaccines. This includes all components of the EPI vaccines.
- History of anaphylactic shock.
- Any abnormal vital sign.
- Any moderate or severe acute illness.
- History of administration of a non-study vaccine within 30 days prior to administration of study vaccine, other than EPI vaccinations (Note: EPI vaccines other than that stipulated in the study must be given at least 14 days prior to the investigational vaccine.)
- Individuals who receive treatment with radiotherapy or immunosuppressive therapy, including cytotoxic agents or systemic corticosteroids (if systemic corticosteroids are administered for 14 days at a dose of 20 mg/day of prednisone or equivalent), e.g., for cancer or an autoimmune disease, or planned receipt throughout the study. Inhaled/nebulized, intra-articular, epidural, or topical (skin or eyes) corticosteroids within indicated dosage are permitted.
- Administration of immunoglobulins and/or any blood products or anticipation of such administration during the study period.
- History of known disturbance of coagulation or blood disorder that could cause anemia or excess bleeding (e.g., thalassemia, coagulation factor deficiencies, severe anemia at birth).
- History of suspected primary immunodeficiency.
- History of meningitis, seizures or any neurological disorder.
- A family history of congenital or hereditary immunodeficiency.
- The infant is a direct descendant (child or grandchild) of any person employed by the Sponsor, the CRO, the investigator, study site personnel.
- Any medical or social condition that in the opinion of the investigator may compromise the well-being of the study participant, interfere with the study objectives, pose a risk to the study participant, or prevent the study participant from completing the study follow-up.

Intervention / Treatment |
---|---|
Experimental: Walvax PCV13-TT
Primary Vaccination: A total of approximately 300 infants 6-8 weeks of age will be enrolled and assigned randomly to receive at 2, 4, and 12-15 months of age 1 dose of PCV13-TT. Standard EPI vaccines will be administered concomitantly. Booster Vaccination: At 12-15 months of age (8 to 11 months after the 2nd dose of the primary series), infants will receive a booster dose of PCV13-TT. |
PCV13-TT is supplied as 0.5 mL prefill syringe (PFS), with 0.5 mL suspension for intramuscular injection. After shaking, the vaccine is a homogenous, white suspension. Each dose (0.5 mL) of PCV13-TT contains pneumococcal polysaccharide serotypes 1, 3 4, 5, 6A 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F which are conjugated to TT carrier protein individually. The vaccine is formulated in phosphate-buffered saline containing 4.25 mg/dose sodium chloride (NaCl), 44.35 μg/dose sodium dihydrogen phosphate (NaH2PO4), 19.0 μg/dose disodium hydrogen phosphate (Na2HPO4), and contains 0.5 mg/dose of aluminum phosphate as an adjuvant; no preservatives added. |
Active Comparator: Pfizer PCV13
Primary Vaccination: A total of approximately 300 infants 6-8 weeks of age will be enrolled and assigned randomly to receive at 2, 4, and 12-15 months of age 1 dose of PCV13. Standard EPI vaccines will be administered concomitantly. Booster Vaccination: At 12-15 months of age (8 to 11 months after the 2nd dose of the primary series), infants will receive a booster dose of PCV13. |
PCV13 is a suspension for intramuscular injection available in 0.5 mL single-dose prefilled syringes.
Each 0.5 mL dose of PCV13 is formulated to contain approximately 2.2 μg of each of S. pneumoniae serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F, 23F polysaccharides, 4.4 μg of 6B polysaccharides, 34 μg 26 CRM197 carrier protein, 100 μg polysorbate 80, 295 μg succinate buffer and 125 μg aluminum as aluminum phosphate adjuvant.
