NCT ID NCT02563327

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This completed Phase 3 study measured how high doses of the tuberculosis drugs rifapentine and moxifloxacin move through the body in 53 adults with TB. Participants gave multiple blood samples to track drug levels. The goal was to understand the best doses to kill TB bacteria while avoiding side effects. This research may help refine future TB treatment regimens.
