Trial Outcomes & Findings for Safety and Immunogenicity of 20vPnC in Toddlers With 2 Prior Doses of Prevenar 13 (NCT NCT05408429)

NCT ID: NCT05408429

Last Updated: 2024-09-19

Results Overview

Local reactions included redness, swelling, and pain at the injection site, recorded by parents/legal guardians of participants in an electronic diary (e-diary). Redness and swelling were measured and recorded in measuring device (caliper) units. 1 measuring device unit = 0.5 centimeter (cm). Redness and swelling were graded as mild (greater than \[\>\] 0 to 2.0 cm), moderate (\>2.0 to 7.0 cm) and severe (\>7.0 cm). Pain at injection site was graded as mild (hurt if gently touched example, whimpered, winced, protested, or withdrew), moderate (hurt if gently touched, with crying), and severe (caused limitation of limb movement). 95 percent (%) confidence interval (CI) was based on Clopper and Pearson method.

Participant Flow

Participants included in this study were toddlers greater than or equal to (\>=) 12 to less than (\<) 24 months of age who had received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) (Prevenar 13) in infancy (prior to 12 months of age).

A total of 356 participants were enrolled and randomized to receive either 2 dose of 20-valent pneumococcal conjugate vaccine (20vPnC), 1 dose of 20vPnC or 1 dose of 13vPnC.

PRIMARY outcome

Timeframe: Within 7 days after last vaccination (for reporting arm 2-Dose 20vPnC last vaccination was Dose 2 and for 1-dose 20vPnC and 13vPnC Control it was Dose 1)

Population: Safety analysis set included all participants who received at least 1 dose of 20vPnC or 13vPnC and had safety data assessed after any dose. Here, "Number of Participants Analyzed" signifies number of participants with any e-diary data reported after the last vaccination.

Systemic events included fever, decreased appetite, drowsiness/increased sleep and irritability, recorded by parents/legal guardians of participants using an e-diary. Fever: temperature \>=38.0 degree Celsius (C) and categorized as \>=38.0 to 38.4 degree C,\>38.4 to 38.9 degree C,\>38.9 to 40.0 degree C and \>40.0 degree C. Decreased appetite was graded as mild (decreased interest in eating), moderate (decreased oral intake) and severe (refusal to feed). Drowsiness was graded as mild (increased/prolonged sleeping bouts), moderate (slightly subdued, interfered with daily activity) and severe (disabling, not interested in usual daily activity). Irritability was graded as mild (easily consolable), moderate (required increased attention) and severe (inconsolable, crying could not be comforted). 95% CI was based on Clopper \& Pearson method.

PRIMARY outcome

Timeframe: From last vaccination to 1 Month after last vaccination (for reporting arm 2-Dose 20vPnC last vaccination was Dose 2 and for 1-dose 20vPnC and 13vPnC Control it was Dose 1)

Population: Safety analysis set included all participants who received at least 1 dose of 20vPnC or 13vPnC and had safety data assessed after any dose. Here, "Number of Participants Analyzed" signifies the number of participants in the specified group who received the last vaccination.

An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. 95% CI was based on the Clopper and Pearson method. AEs reported in this endpoint excluded local reactions and systemic events collected from an e-diary.

A SAE was any untoward medical occurrence that: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/ incapacity; was a congenital anomaly/birth defect; was a suspected transmission via a Pfizer product of an infectious agent, pathogenic or non-pathogenic, was considered serious and other important medical events. 95% CI was based on the Clopper and Pearson method.

Population: Evaluable immunogenicity population (EIP) included all participants who were eligible, received vaccinations to which they were randomized, had at least 1 valid immunogenicity result from 1 month after the last assigned vaccination collected within 27 to 56 days after the dose, had no other major protocol deviations as determined by clinician. "Number of Participants analyzed"= participants in EIP. "Number analyzed"= participants with valid IgG results for specified serotype.

Pneumococcal serotype-specific IgG concentrations were measured for serum samples for 7 additional serotypes: 8, 10A, 11A, 12F, 15B, 22F, 33F. The predefined level was 0.35 microgram per milliliter (mcg/mL) for all 7 additional serotypes. 95% CI was based on the Clopper and Pearson method.
