NCT ID NCT07094711
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether the BCG vaccine, originally developed for tuberculosis, can safely treat Mycobacterium avium complex (MAC) lung disease. Researchers will give 48 adults either a single BCG injection or a placebo and monitor them for side effects, immune responses, and sputum cultures over 12 months. The goal is to see if BCG can boost the immune system to better control the infection.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
BCG vaccine (Bacillus Calmette-Guerin)
What this could lead to
If it works, this could point toward a new treatment option for MAC lung disease, a chronic infection that is hard to treat.
What could go wrong
This is a small, early-phase trial with only 48 participants. The BCG vaccine may not improve outcomes and could cause side effects like injection site reactions or flu-like symptoms.
