Filter by:The Trep-AB clinical trial will test the efficacy of an investigational neuropenetrative drug, Linezolid (LZD), compared to standard treatment, Benzathine penicillin G (BPG), for early syphilis in humans. The overarching idea of the work proposed herein is to investigate the use of LZD to treat syphilis, conducting a randomized controlled clinical trial to evaluate this new indication of a known antibacterial agent.
Syphilis is a sexually transmitted infection that causes genital sores and rash, but in some circumstances may result in more severe and unexpected symptoms. These severe symptoms could include eye infections, meningitis (infection of the membranes covering the brain and spinal cord), and liver infection. If not properly treated, syphilis can also lead to heart problems and dementia (a decline in reasoning, memory and other mental abilities) years down the road. There has been an increase in the number of reported cases of syphilis in North America, Europe, and Australia over the past decade. The number of new syphilis infections in Canada has increased roughly 10-fold over the past 10 years. Since 1943, the antibiotic penicillin has been used to treat syphilis; however, very little information has been gathered to determine the proper dose of penicillin or appropriate duration of treatment. Added to this, several studies have shown that the recommended dose of penicillin fails to cure syphilis in 20-30% of patients. Since the number of people infected with syphilis is increasing, and since syphilis has the potential to cause serious disease, the investigators need better information on how to treat syphilis effectively. This study aims to determine whether the current dose of penicillin recommended to treat syphilis is sufficient to cure the infection. Specifically the investigators will try to determine whether the amount of penicillin in your blood 3 and 7 days after receiving treatment for syphilis is sufficient to cure the infection as demonstrated by a blood test 6 or 12 months from now. This study is a multi-centered trial based in Ottawa but with centers recruiting both in Montreal and Toronto. A total of 120 participants with syphilis will be recruited into this study. The treatment you will receive for syphilis in this study does not differ from that you would receive normally; the investigators are only observing the levels of penicillin in your blood and relating them with the outcome of treatment.
