Evaluation of Safety and Immunogenicity of Inactivated Adjuvanted Polio Vaccine in Comparison With Licensed Inactivated Poliovirus Vaccine

A Phase III, Double Blind, Randomized, Active Controlled Study to Evaluate Safety and Immunogenicity of Inactivated Adjuvanted Polio Vaccine in Comparison With Licensed Inactivated Poliovirus Vaccine

• Status: Completed
• Phase: Phase 3
• Study type: Interventional
• Enrollment: 1,072 (actual)
• Sponsor: Serum Institute of India Pvt. Ltd. · Industry
• Sex: All
• Age: 6 Weeks – 8 Weeks
• Healthy volunteers: Accepted

Summary

This Phase III study has been designed to compare the SII Inactivated Salk Polio Vaccine (Adsorbed) with Sii licensed IPV by testing the vaccine in infants (three doses administered 4 weeks apart, starting at 6-8 weeks of age) in order to demonstrate the non-inferiority in the induction of specific poliovirus neutralizing antibody (PVNA) to poliovirus type 1, type 2 and type 3 by these vaccines. The study will also evaluate lot-to-lot consistency in the manufacture of SII Inactivated Salk Polio Vaccine (Adsorbed) by demonstrating equivalence in the induction of PVNA across three production lots.

Detailed description

The study is designed as a double-blind, randomized, active-controlled Phase III study with four groups of infants (n=268 per group) receiving either SII Inactivated Salk Polio Vaccine (Adsorbed) from the three lots or Sii licensed IPV. Participants will be screened for eligibility with their parental consent and will be selected for the study according to inclusion and exclusion criteria. A total of 1072 participants will be enrolled. Following vaccination, enrolled participants will remain in the clinic for at least 30 minutes for observation. During this time, they will be closely monitored for any immediate adverse events. Safety will be evaluated by active surveillance for solicited adverse events over the 4-day period after each vaccination in all participants. In addition, surveillance for unsolicited AEs and SAEs will be carried out over the period from first vaccination and 28 days after the third vaccination in all participants. The immunogenicity will be assessed by measuring the PVNA to poliovirus type 1, type 2 and type 3 using a standardized microneutralization test in the sera samples of the participants.
