Phase 3
Completed
Conditions
Pneumococcal Infections
Interventions
Drug: Rotarix™
Drug: Infanrix™ hexa
Drug: Prevenar 13™
Registration Number
NCT04031846
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This study will evaluate the safety and tolerability and immunogenicity of V114 when administered to 2-month old infants. The primary hypotheses are: 1) V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes between V114 and Prevenar 13™ based on response rates at 30 days post toddler dose (PTD); 2) V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on the response rates at 30 days PTD; 3) V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes between V114 and Prevenar 13™ based on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobin G (IgG) geometric mean concentrations (GMCs) at 30 days PTD; and 4) V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on anti-PnPs serotype-specific IgG GMCs at 30 days PTD.

Primary Outcome Measures
NameTimeMethod
Anti-pneumococcal Polysaccharide (PnPs) Serotype-specific Immunoglobin G (IgG) Geometric Mean Concentrations (GMC) for Each Serotype at 30 Days Post Toddler Dose (PTD)30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for each serotype using pneumococcal electrochemiluminescence (PnECL). The Geometric Mean Concentration (GMC) for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F); and the 2 serotypes unique to V114 (Serotypes 22F and 33F) was assessed. Per protocol, within-group CIs were not calculated.

Percentage of Participants That Report at Least 1 Solicited Injection-site Adverse Event (AE)Up to 14 days post any vaccination (up to approximately study month 13)

An AE is any untoward medical occurrence in a participant temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of a study intervention. Injection-site AEs solicited on the Vaccine Report Card (VRC) consisted of erythema (redness), induration (hard lump), pain (tenderness) and swelling.

Percentage of Participants That Report at Least 1 Solicited Systemic AEUp to 14 days post any vaccination (up to approximately study month 13)

An AE is any untoward medical occurrence in a participant temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of a study intervention. Systemic AEs solicited on the VRC consisted of decreased appetite (loss of appetite), irritability, somnolence (drowsiness) and urticaria (hive/welts).

Percentage of Participants That Report at Least 1 Vaccine-related Serious Adverse Event (SAE)Up to 6 months post last vaccination (up to approximately study month 20)

A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, is a cancer, is an overdose, or is another important medical event. The relatedness of a vaccine to a SAE is determined by an investigator who is a qualified physician.

Percentage of Participants Who Meet Serotype-specific IgG Threshold Value of ≥0.35 μg/mL for Each Serotype at 30 Days PTD30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for the 15 serotypes using pneumococcal electrochemiluminescence (PnECL). The percentage of participants that achieve the threshold value of ≥0.35 μg/mL for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F); and the 2 serotypes unique to V114 (Serotypes 22F and 33F) was assessed.

Secondary Outcome Measures
NameTimeMethod
Anti-rotavirus Immunoglobulin A (IgA) Geometric Mean Titers (GMTs) at 30 Days Post Primary Series (PPS) of Rotarix™30 days PPS (Up to approximately study month 3)

Sera from participants was used to measure vaccine-induced antibodies in response to vaccination with Rotarix™ by assessing the GMT for IgA. Per protocol, within-group CIs were not calculated.

Percentage of Participants Who Meet Antigen-Specific Threshold Value for Each Antigen in Infanrix™ Hexa at 30 Days PTD30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced responses to 10 pre-specified Infanrix™ hexa antigens with the following threshold (% ≥) values: Diphtheria toxoid-0.1 international unit (IU)/mL;Tetanus toxoid-0.1 IU/mL; Pertussis pertussis toxin (PT)-5 endotoxin unit (EU)/mL; Pertussis filamentous hemagglutinin (FHA)-5 EU/mL; Pertussis pertactin (PRN)-5 EU/mL; Haemophilus influenzae type b (Hib) polyribosylribitol phosphate (PRP)-0.15 μg/mL; hepatitis B surface antigen (HBsAg)-10 mIU/mL; Poliovirus 1,2 and 3-1:8 neutralizing antibodies (NAb) dilution.

Anti-PnPs Serotype-specific IgG GMCs for Each Serotype at 30 Days PPS30 days PPS (Up to approximately study month 3)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for each serotype using PnECL. The GMC for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F); and the 2 serotypes unique to V114 (Serotypes 22F and 33F) was assessed. Per protocol, within-group CIs were not calculated.

Percentage of Participants Who Meet Serotype-specific IgG Threshold Value of ≥0.35 μg/mL for Each Serotype at 30 Days PPS30 days PPS (Up to approximately study month 3)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for the 15 serotypes using PnECL. The percentage of participants that achieve the threshold value of ≥0.35 μg/mL for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F); and the 2 serotypes unique to V114 (Serotypes 22F and 33F) was assessed.

Anti-PnPs Serotype-specific Opsonophagocytic Activity (OPA) GMTs for Each Serotype at 30 Days PTD30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific OPA using the multiplexed opsonophagocytic assay (MOPA). The GMT for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F); and the 2 serotypes unique to V114 (Serotypes 22F and 33F) was assessed. The within-group CIs were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

Percentage of Participants Who Achieved the IgG Serotype-Specific Threshold Value of ≥0.35 μg/mL For Protocol Pre-Specified Serotypes at 30 Days PTD30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific IgG for the 15 serotypes using PnECL. As pre-specified in the protocol the percentage of participants from the two serotypes unique to V114 (Serotypes 22F and 33F) are presented, as well as the percentage of participants with the lowest response rate from any of the 13 shared serotypes randomized to Prevenar 13™ (Serotype 3).

Percentage of Participants Who Meet Serotype-specific OPA Threshold Value for Each Serotype at 30 Days PTD30 days PTD (Up to approximately study month 14)

Sera from participants was used to measure vaccine-induced anti-PnPs serotype-specific OPA using the MOPA. The threshold dilution (% ≥) for each of the 13 serotypes shared by both V114 and Prevenar 13™ (Serotypes 1 to 23F) were as follows: 1:9, 1:19, 1:34, 1:27, 1:232, 1:40, 1:61, 1:151, 1:62, 1:115, 1:31, 1:113, 1:55. For Serotypes 22F and 33F the threshold dilution was 1:15 and 1:20 respectively. The within-group CIs were based on the exact binomial method of Clopper and Pearson.
