Could a common antibiotic beat stubborn joint infections?

NCT ID NCT05902221

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This trial investigates whether adding the antibiotic rifampicin to standard treatment improves outcomes for people with prosthetic joint infections caused by Cutibacterium acnes bacteria. These infections are hard to treat because the bacteria form a protective biofilm. The study involves 235 adults with infected hip, knee, or shoulder replacements who will receive either standard antibiotics alone or standard antibiotics plus rifampicin for 12 weeks. Researchers will track treatment failures and side effects to see if the combination works better.

What this could mean

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

Active substance

rifampicin

What this could lead to

If adding rifampicin works, it could become a standard part of treatment for these stubborn joint infections, reducing the need for repeat surgeries.

What could go wrong

This is a phase 3 trial, but rifampicin may cause side effects like liver problems or drug interactions, and the infection might still return.
