First seen Nov 18, 2025 · Last updated May 14, 2026 · Updated 22 times
Summary
This study tests whether adding doxycycline to the standard penicillin shot works better for treating early syphilis in people with HIV. About 688 adults will be randomly assigned to get either penicillin alone or penicillin plus a 7-day course of doxycycline pills. The main goal is to see if the combination leads to a better drop in syphilis blood test levels at 24 and 48 weeks.
