BACKGROUND: Combination vaccines simplify vaccination visits and improve coverage and timeliness. DTaP5-HB-IPV-Hib is a new investigational, fully-liquid, combination vaccine designed to protect against 6 infectious diseases, including 5 pertussis antigens and OMPC instead of PT as conjugated protein for Hib component.
METHODS: In this multicenter, double-blind, comparator-controlled, Phase III study (NCT01480258) conducted in Sweden, Italy, and Finland, healthy infants were randomized 1:1 to receive one two immunization regimens. The DTaP5-HB-IPV-Hib Group received the investigational hexavalent vaccine (DTaP5-HB-IPV-Hib) and the Control Group received Infanrix-hexa (DTPa3-HBV-IPV/Hib) at 2, 4 and 11-12months of age. Both groups received concomitantly Prevnar 13 (PCV13) and Rotateq (RV5) or Rotarix (RV1) at 2, 4months of age and PCV13 at 11-12months. Subjects administered RV5 received a 3rd dose at 5months of age.
RESULTS: A total of 656 subjects were randomized to the DTaP5-HB-IPV-Hib Group and 659 subjects to Control Group. Immune responses to all vaccine antigens post-toddler dose were non-inferior in the DTaP5-HB-IPV-Hib Group as compared to the Control Group. Additionally, the post-dose 2 and pre-toddler DTaP5-HB-IPV-Hib anti-PRP responses were superior. The DTaP5-HB-IPV-Hib Group responses to concomitant RV1 were non-inferior compared to the Control Group. Solicited adverse event rates after any dose were similar in both groups, except for higher rates of pyrexia (6.4% difference; 95% CI: 1.5,11.3) and somnolence (5.8% difference; 95% CI: 1.7,9.8) in the DTaP5-HB-IPV-Hib Group. Vaccine-related serious adverse events occurred infrequently in the DTaP5-HB-IPV-Hib Group (0.3%) and the Control Group (0.5%).
CONCLUSIONS: The safety and immunogenicity of DTaP5-HB-IPV-Hib is generally comparable to Control when administered in the 2, 4, 11-12month schedule. Early Hib responses were superior versus Control. DTaP5-HB-IPV-Hib could provide a new hexavalent option for pediatric combination vaccines, aligned with recommended immunizations in Europe.
