Clinical Trial Summary

The study aims to evaluate the efficacy of linezolid for the treatment of syphilis.


Clinical Trial Description

This will be a randomized, open-label, non-comparative, adaptive pilot trial to evaluate the efficacy of linezolid 600mg orally, twice a day, for five or ten days, using a contemporaneous historical control group benzathine penicillin G (single dose of 2.4 million units) in participants with and without HIV infection. In total, 24 participants will be enrolled across multiple clinical sites in the United States. Participants will participate in follow-ups to monitor clinical outcomes and serological response (RPR titer) at 1 month, 3 months, and 6 months. Study findings may identify an efficacious alternative syphilis treatment to penicillin that is effective for people living with HIV. Study findings may also help address the crisis of penicillin shortages, difficulty in administration, and offer options for those with penicillin allergy. ;
