Clinical Trial Comparing the Effectiveness of Cefixime Versus Penicillin G for Treatment of Early Syphilis
University of Southern California
Summary
This study aims to evaluate the efficacy of cefixime compared to benzathine penicillin G in the treatment of syphilis.
Description
This will be a randomized, multisite, open-label, non-inferiority clinical trial to evaluate the effectiveness of cefixime (400mg orally, twice a day, for 10 days) compared to benzathine penicillin G (2.4 million units, intramuscularly) in patients with and without HIV infection. In total, 400 participants with early syphilis will be enrolled from 9 clinical sites in the U.S. and Peru. Participants will participate in follow-ups to monitor clinical outcomes and serological response (RPR titer) every 3 months for 9 months. Study findings may identify an efficacious alternative syphilis treatmen…
