Immunogenicity, Safety and Tolerability of the Typhoid Fever Vaccine Candidate M01ZH09 in Healthy Adults

Typhoid Clinical Trial

Official title:
A Randomised, Double-blind, Placebo-controlled, Single Dose, Dose Escalation Study to Determine the Immunogenicity, Safety and Tolerability of S. Typhi (Ty2 aroC-ssaV-) ZH9 at Doses of 5.0 x 10E9 CFU, 7.5 x 10E9 CFU, 1.1 x 10E10 and 1.7 x 10E10 CFU and 1.7 x 10E10 CFU, Following Oral Administration to Healthy, Typhoid Vaccine naïve Subjects in the USA.

Clinical Trial Summary

This study is to investigate the safety, tolerability and immunogenicity of the typhoid fever vaccine candidate M01ZH09 manufactured at commercial scale, at a new manufacturing facility. The vaccine will be delivered as a single oral dose to healthy, typhoid vaccine-naïve adults.

Clinical Trial Description

This was a randomised, double-blind, placebo-controlled, single dose, dose escalation study with 4 dosing cohorts. Within each cohort, 45 evaluable subjects were planned (36 subjects receiving M01ZH09, 9 receiving placebo). ;
