Study Endpoints

Primary Endpoints

Infants Groups 1 and 2: Percentage of Participants With Vaccine Seroresponse Measured by Serum Bactericidal Assay Using Human Complement (hSBA) at 30 Days Post Second Dose of MenACYW Conjugate Vaccine or MENVEO
Baseline (Day 0) and 30 days post second dose (12 to 13 MoA) of MenACYW conjugate vaccine or MENVEO, maximum of 14 months

Functional meningococcal antibody activity against serogroups A, C, Y, and W were measured in a serum bactericidal assay utilizing the hSBA. The hSBA vaccine seroresponse was defined as a post-vaccination titer \>= 1:16 for participants with pre-vaccination hSBA titer \< 1:8, or a post-vaccination titer \>= 4-fold increase from baseline for participant with pre-vaccination hSBA titer \>= 1:8.

Secondary Endpoints

Infants Groups 1 and 2: Percentage of Participants Who Achieved Antibody Titer (Seroprotection) >=1:8 by hSBA at 30 Days Post Second Dose of MenACYW Conjugate Vaccine or MENVEO
At 30 days post second dose (12 to 13 MoA) of MenACYW conjugate vaccine or MENVEO
Infants Groups 1 and 2: Percentage of Participants With hSBA Antibody Titer >= 1:4 and >= 1:8
PPAS1: At 30 days post first dose (6 to 7 MoA); PPAS2: At Baseline (pre-dose on Day 0) and 30 days post second dose (12 to 13 MoA); and PPAS3: At 6 months post first dose (6 to 7 MoA) of MenACYW conjugate vaccine or MENVEO
Infants Groups 1 and 2: Geometric Mean Titers Against Meningococcal Serogroups A, C, W, and Y
PPAS1: At 30 days post first dose (6 to 7 MoA); PPAS2: At Baseline (pre-dose on Day 0) and 30 days post second dose (12 to 13 MoA); and PPAS3: At 6 months post first dose (6 to 7 MoA) of MenACYW conjugate vaccine or MENVEO

What is Haemophilus b Conjugate Vaccine used for?

Haemophilus b Conjugate Vaccine is being studied for use in healthy volunteers in the context of meningococcal infection prevention. It is an investigational vaccine evaluated in a Phase 3 clinical trial to assess its immunogenicity and safety when administered with routine pediatric vaccines in healthy infants and toddlers.

Who makes Haemophilus b Conjugate Vaccine?

Haemophilus b Conjugate Vaccine is developed by Sanofi, a company listed on the stock exchange under the ticker symbol SNY. Sanofi is conducting clinical research on this vaccine to evaluate its potential use in preventing meningococcal infection in healthy pediatric populations.

What phase is Haemophilus b Conjugate Vaccine in?

Haemophilus b Conjugate Vaccine is in Phase 3 clinical development. It is an investigational vaccine, not yet approved by regulatory authorities. The Phase 3 trial has been completed, with results expected to inform further development and potential regulatory submissions.

What clinical trials is Haemophilus b Conjugate Vaccine in?

Haemophilus b Conjugate Vaccine is associated with one completed Phase 3 clinical trial, identified as NCT03691610. This study evaluated the immunogenicity and safety of a quadrivalent meningococcal conjugate vaccine administered concomitantly with routine pediatric vaccines in healthy infants and toddlers, enrolling 950 participants in the United States and Puerto Rico.

Is Haemophilus b Conjugate Vaccine the same as a quadrivalent meningococcal conjugate vaccine?

The clinical trial NCT03691610 evaluates a quadrivalent meningococcal conjugate vaccine, which is the vaccine under investigation.
