Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase 1 study to evaluate the safety and immunogenicity of the semisynthetic saponin adjuvant TQL1055 administered in combination with an acellular pertussis vaccine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The recent increase in the incidence of pertussis has prompted the need for improvements to current acellular pertussis vaccines. Use of novel adjuvants is one approach to such improvement. TQL1055 is a rationally designed, semisynthetic analog of the licensed Quillaja saponin (QS)-21. It has been designed to maintain adjuvant activity with improved tolerability and greater ease of manufacture.

This is a Phase 1, randomized, double blind, active-controlled sequential-group study, designed to evaluate the safety, tolerability, and immunogenicity of the combination of TQL1055 and acellular pertussis vaccine. The dose of TQL1055 will increase by group.
