Study Summary

This is a trial to evaluate the safety and immunogenicity of double mutant heat-labile toxin LTR192G/L211A (dmLT) from Enterotoxigenic Escherichia coli (ETEC) by oral, sublingual, or intradermal vaccination in approximately 135 healthy adult volunteers, age 18-45 years. Study duration is approximately 2.5 years, with each participant duration for up to 9 months depending on the route of dmLT administered. There is no specific hypothesis being tested in this study. The primary objective of this study is to assess the reactogenicity, safety, and tolerability of dmLT when administered in three sequential doses, over a range of dosages by oral, sublingual, or intradermal routes.
