NCT ID NCT06446245

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether adding the antibiotic doxycycline to standard treatment can reduce deaths and severe brain damage in adults with tuberculosis of the brain or its lining. About 200 participants will receive either doxycycline or a placebo for 8 weeks, alongside usual TB drugs and steroids. The study builds on earlier work showing doxycycline may calm harmful inflammation in TB.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
doxycycline
What this could lead to
If it works, this could point toward a cheap, widely available add-on treatment to lower the high death and disability rates from brain tuberculosis.
What could go wrong
This is a mid-stage trial with only 200 participants, so results may not apply to everyone. Doxycycline can cause side effects like sun sensitivity and stomach upset.
