Brief Title: Bacille Calmette-Guerin (BCG) Vaccine for Immune Protection Against Infections

Effects of BCG Vaccine on the Immune System of Individuals With Cystic Fibrosis, Non-Cystic Fibrosis Bronchiectasis, and Healthy Volunteers

INTRODUCTION

  • Org Study ID: IRB00256425
  • Secondary ID: N/A
  • NCT ID: NCT04884308
  • Sponsor: Johns Hopkins University

BRIEF SUMMARY

This is pilot study of the immunologic effects of intradermal Bacille Calmette-Guerin (BCG) vaccination of adults with cystic fibrosis (CF), non-CF bronchiectasis (NCFB), and healthy volunteers.

DETAILED DESCRIPTION

This single-site, open-label clinical trial to investigate the immune effects of BCG vaccination in adults with cystic fibrosis, non-cystic fibrosis bronchiectasis and healthy volunteers by measuring pre and post vaccination immune responses, BCG uptake and protection against infections, including nontuberculous mycobacteria (NTM). This study will also gather data on study feasibility, tolerability, and safety.
