A Phase I Single Site Open Label Clinical Trial for the Development of a Human BCG Challenge Model to Assess TB Drugs and Vaccines.

Fred Hutchinson Cancer Center·interventional·Posted Oct 24, 2022·Updated Dec 16, 2025

In Brief

A Phase 1 clinical trial evaluating BCG Vaccine USP, Isoniazid, and 1 other intervention for Tuberculosis. Completed, enrolled 20 participants across 1 site.

Detailed Summary

The purpose of the study is to develop a BCG challenge model for use in short term Phase I human trials capable of assessing the ability of TB drugs and/or vaccine-induced immune responses to impact in vivo mycobacterial replication as a method of assessing antimycobacterial agents and/or protective immunity elicited by vaccines or host-directed therapy. The trial will illuminate the nature of local and systemic immune responses to BCG and treatment response, as well as demonstrate our local capacity for newer, more innovative study designs.
