A Study to Evaluate the Safety, Tolerability, and Immunogenicity of Two Lots of V114 in Healthy Infants (V114-008)

Phase 2
Completed
Conditions
Pneumococcal Infections
Registration Number
NCT02987972
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study is designed to evaluate the safety, tolerability, and immunogenicity of two different lots of V114 in healthy infants 6 to 12 weeks (\>=42 days to \<=90 days) of age. The primary hypothesis of the study is that the proportion of participants receiving V114 who have serotype specific IgG \>=0.35 mcg/mL for each of pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F at 1 month after Dose 3 is non-inferior to that for recipients of Prevnar 13™.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving the Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody Threshold Value of ≥0.35 µg/mL for the 13 Common Serotypes in V114 and Prevnar 13™: 1 Month Post Vaccination 31 month post vaccination 3 (Month 5)

Serotype-specific pneumococcal IgG antibody was measured using the Meso-Scale Discovery (MSD) Pneumococcal electrochemiluminescence assay (Pn ECL). The percentage of participants with serotype-specific IgG ≥0.35 µg/mL was summarized for each serotype.

Percentage of Participants Who Discontinued From the Study Due to an Adverse EventUp to 1 month post Vaccination 4 (up to 14 months)

The percentage of participants who discontinued the study because of an AE (as defined above) was assessed.

Geometric Mean Concentration of Serotype-specific Pneumococcal IgG Antibody for the 13 Common Serotypes in V114 and Prevnar 13™ and the 2 Serotypes Unique to V114: 1 Month Post Vaccination 31 month post Vaccination 3 (Month 5)

Serotype-specific pneumococcal IgG antibody will be assayed using the Meso-Scale Discovery (MSD) Pn electrochemiluminescence assay. The geometric mean concentration (GMC) of serotype-specific IgG will be assessed.

Percentage of Participants With a Solicited Injection-site Adverse EventUp to 14 days post any vaccination

Injection-site AEs solicited on the Vaccine Report Card were redness, swelling, hard lump, and pain/tenderness. The percentage of participants with 1 or more solicited injection-site AEs was assessed.

Percentage of Participants With a Solicited Systemic Adverse EventUp to 14 days post any vaccination

Systemic AEs solicited on the Vaccine Report Card were fever, irritability, drowsiness, hive/welts, and appetite loss. The percentage of participants with 1 or more solicited systemic AEs was assessed.

Percentage of Participants Who Experience at Least 1 Adverse EventUp to 1 month post Vaccination 4 (up to 14 months)

An adverse event (AE) is defined as any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The percentage of participants with one or more AEs was assessed.

Secondary Outcome Measures
NameTimeMethod
Geometric Mean Concentration of Serotype-specific Pneumococcal IgG Antibody for the 13 Common Serotypes in V114 and Prevnar and the 2 Serotypes Unique to V114: Pre-vaccination 4Before Vaccination 4 (Month 10 to 13)

Serotype-specific pneumococcal IgG antibody was assayed using the MSD Pn electrochemiluminescence assay.

Geometric Mean Concentration of Serotype-specific Pneumococcal IgG Antibody for the 13 Common Serotypes in V114 and Prevnar and the 2 Serotypes Unique to V114: 1 Month Post Vaccination 41 month post vaccination 4 (Month 11-14)

Serotype-specific pneumococcal IgG antibody was assayed using the MSD Pn electrochemiluminescence assay.
