Brief Summary

The goal of this clinical trial is to evaluate the immunogenicity and safety of a novel 13-valent pneumococcal polysaccharide conjugate vaccine (PCV13-TT) as compared to Pfizer's 13-valent pneumococcal conjugate vaccine (PCV13) when co-administered with local EPI Vaccines at 2, 4, and 12-15 months of age, to healthy infants in Indonesia. This study aims to demonstrate the non-inferiority of the serotype-specific immune responses elicited by the novel PCV13-TT as compared to PCV13 one month after the booster dose.

Conditions

Pneumococcal Disease, Invasive

Secondary Outcomes (9)

• Solicited local and systemic adverse events after each dose

  within 30 min and 7 days after each dose

• Unsolicited adverse events after each dose

  within 30 days after each dose

• Serious adverse events throughout the study

  from dose 1 until 6 months after booster dose

• Immune response to primary series as measured by serotype-specific IgG

  1 month after the 2nd dose

• Immune response to primary series as measured by serotype-specific IgG GMC

  1 month after the 2nd dose

Other Outcomes (6)

• Exploratory_Non-interference

  1 month after the 2nd dose

• Exploratory_Non-interference

  1 month after the 2nd dose

• Exploratory_Non-interference

  1 month after the 2nd dose with respect to baseline titers

Walvax PCV13-TT

EXPERIMENTAL

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.

Interventions

Walvax PCV13-TT BIOLOGICAL

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.

Pfizer PCV13 BIOLOGICAL

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.
