Can weekly tests pinpoint when STIs are truly gone?
NCT ID NCT06216964
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This study follows 140 adults who have been treated for uncomplicated chlamydia or gonorrhea infections. Participants will have weekly swabs or urine tests to check when the bacteria's genetic material (RNA) disappears from the body, up to 4 weeks after starting treatment. The goal is to understand how quickly these infections clear at different body sites, such as the genitals, throat, or rectum, which could help guide future testing and care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Weekly NAAT (PCR) diagnostic tests after treatment
- What this could lead to
- If successful, this could help doctors know when it's safe to assume an infection is cleared, potentially reducing unnecessary follow-up tests and anxiety.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't change how infections are treated. Results may vary by infection site and may not apply to everyone.
