Fully liquid six-in-one infant vaccine (DTwP-HepB-IPV-Hib) given as a primary series

A Prospective, Multi-national, Multi-center, Open-label, Randomized, Active Controlled, Parallel Group, Operationally Seamless Phase II/III Clinical Study to Evaluate the Immunogenicity, Safety and Lot-to-lot Consistency of LBVD, a Fully Liquid Hexavalent Diphtheria-tetanus-whole Cell Pertussis-hepatitis B-poliovirus (Inactivated)-Haemophilus Influenzae Type b Conjugate (DTwP-HepB-IPV-Hib) Vaccine, Compared to Co-administration of DTwP-HepB-Hib Vaccine and IPV Vaccine in Healthy Infants at 6-, 10-, and 14-week of Age as Primary Series

Phase2; Phase3 Interventional LG Chem · NCT06947499

This tests a fully liquid six-in-one vaccine (diphtheria, tetanus, whole-cell pertussis, hepatitis B, inactivated polio, and Hib) in healthy infants at 6, 10, and 14 weeks to see if it gives similar immune responses and safety compared with separate pentavalent plus polio shots.

What this trial studies

This Phase II/III trial enrolls healthy full-term infants to receive a three-dose primary series of LBVD, a fully liquid hexavalent DTwP-HepB-IPV-Hib vaccine, at 6, 10, and 14 weeks of age. In Stage 1 (Phase 2) the vaccine's immunogenicity and safety are compared to the licensed control regimen of pentavalent vaccine plus inactivated poliovirus vaccine given as separate injections. In Stage 2 (Phase 3) the trial tests non-inferiority of LBVD and assesses lot-to-lot consistency across three separate manufactured lots, with primary endpoints measured four weeks after the third dose. Participants are monitored for adverse events and antibody responses to each antigen to determine whether LBVD can replace the separate vaccines.

Who should consider this trial

Good fit: Healthy full-term infants aged 6 to 8 weeks, weighing at least 3.2 kg, with parental informed consent and no prior receipt of the excluded vaccines are ideal candidates.

Not a fit: Infants with prior relevant infections or prior vaccination against these antigens, recent exposure to those infections, fever, immunosuppression, or mothers who are HepB antigen- or HIV-positive are unlikely to be eligible or to gain benefit from participation.

Why it matters

Potential benefit: If successful, LBVD could let infants receive one fully liquid six-in-one injection instead of multiple shots, reducing the number of injections and simplifying immunization schedules.

How similar studies have performed: Other licensed hexavalent combination vaccines have shown good immunogenicity and acceptable safety, so the combination approach is established though product-specific data are still needed.
