NCT04264598

Brief Summary

The purpose of this phase I study is to evaluate the safety of a Sabin Inactivated Poliovirus Vaccine (sIPV) in adults and children, and the safety and immunogenicity of it in infants. 20 adults aged 18\~45 years and 20 children aged 4 years were only administered one dose of sIPV with medium D antigen content. 60 infants aged 2 months (60\~90 days) were randomized to receive three doses of sIPV with medium D antigen content, conventional IPV (cIPV, manufactured by Sanofi Pasteur) or sIPV (manufactured by the Institute of Medical Biology, the Chinese Academy of Medical Biology), respectively, on the month 0, 1, 2 schedule. Serum samples were collected before the 1st dose and 30 days after the 3rd dose vaccination to assess the immunogenicity in infants. Adverse events occurring within 30 days after each dose were collected to assess the safety.

Outcome Measures

Primary Outcomes (1)

  • The seroconversion rates (SCRs) of each group 30 days after three-dose regimen

    Subjects whose pre-immune antibody level \< 1:8 and post-immune antibody level ≥ 1:8, or those whose pre-immune antibody level ≥ 1:8 and the increase of post-immune antibody level ≥ 4 folds are considered seroconverted.

    28~42 days

Secondary Outcomes (4)

  • The geometric mean titer (GMT) of each group 30 days after three-dose regimen

    28~42 days

  • The geometric mean fold increase (GMI) of each group 30 days after three-dose regimen

    28~42 days

  • The number of participants who have adverse reactions divided by the total number of participants

    30 days

  • The number of participants who have adverse events (AEs) divided by the total number of participants.

    30 day

Interventions

sIPVBIOLOGICAL

The Medium dosage sIPV was developed by Minhai Biotech Co., LTD. The antigen contents of type I, type II and type III polioviruses in the medium dosage sIPV were 15 DU, 45 DU and 45 DU. The vaccine was in liquid form, 0.5 ml per dose.

The commercialized sIPV was manufactured by Institute of Medical Biology Chinese Academy of Medical Sciences.The antigen contents of type I, type II and type III polioviruses in the commercialized sIPV were 30 DU, 32 DU and 45 DU. The vaccine was in liquid form, 0.5 ml per dose.

Control Infant Group - commercialized sIPV

The commercialized Salk IPV was manufactured by Sanofi Pasteur S.A.The antigen contents of type I, type II and type III polioviruses in the commercialized IPV were 40 DU, 8 DU and 32 DU. The vaccine was in liquid form, 0.5 ml per dose.
