Study design
The safety and immunogenicity of VAXELIS were evaluated in 2 US studies:
Study 0052
- VAXELIS group (N=986): 3 doses at 2, 4, and 6 months and Daptacel® and PedvaxHIB® at 15 months. Control group (N=487): 3 doses of Pentacel® at 2, 4, and 6 months plus Recombivax HB® at 2 and 6 months and Daptacel® and ActHIB® at 15 months.
- Immune responses to RotaTeq® were measured 1 month after the third dose.
Study 0064
- VAXELIS group (N=2,406): 3 doses at 2, 4, and 6 months and Pentacel® at 15 months. Control group (N=402): 4 doses of Pentacel® at 2, 4, 6, and 15 months of age plus Recombivax HB® at 2 and 6 months.
- Immune responses to Prevnar 13® were measured 1 month after the third dose.
All subjects received concomitant vaccines: RotaTeq® at 2, 4, and 6 months and Prevnar 13® at 2, 4, 6, and 15 months of age.2,4
Prior to study initiation, infants in both studies received a dose of hepatitis B vaccine, from birth up to one month of age.2,4
Non-inferiority data
Of all the non-inferiority comparisons in these 2 studies, all were met, but with the following 4 exceptions:
- Non-inferiority criterion—lower bound of 95% CI around GMC ratio >0.67—not met for:
- Anti-FHA after 6-month doses: 0.59 in Study 005 and 0.62 in Study 006
- Anti-pneumococcal serotype 6B after 6-month doses: 0.64 in Study 006
- Anti-PRN after 15-month Pentacel® dose: 0.66 in Study 006
- In Study 005, following the toddler dose of Daptacel®, the non-inferiority criteria for all pertussis response rates and GMCs, including PRN GMC, were met.
- In Study 006, the non-inferiority criteria was met for FHA GMC was met following the toddler dose of Pentacel®.
CI, confidence interval; FHA, pertussis filamentous hemagglutinin; GCM, geometric mean concentration; PRN pertussis pertactin.
