5 Clinical Trials for Various Conditions
This is a phase 4, randomized, open-label, multicenter trial to evaluate the efficacy of a single injected dose of Benzathine Penicillin G (BPG) 2.4 MU (Arm 1) compared to three successive weekly injected doses of BPG 2.4 MU (Arm 2) for treatment of early syphilis in human immunodeficiency virus (HIV)-infected and HIV-uninfected subjects. The study will enroll 560 adults (to achieve 420 evaluable subjects) aged 18 years or older with untreated early syphilis (primary, secondary, or early latent). It will be conducted at 9 sites in the US and last for 48 months with patient participation duration of 12 months. The primary objective is to compare the serological response to therapy in subjects with early (primary, secondary, or early latent) syphilis treated with Benzathine Penicillin G (BPG) 2.4 million units (MU) once or weekly for three successive weeks.
The goal of the study is to evaluate the efficacy of oral cefixime as an alternative treatment for syphilis infection. One hundred adult patients (≥18 years old) with syphilis infection (positive Treponema Pallidum Particle Agglutination assay and RPR titer ≥ 1/8) will be recruited. Participants will be randomized (1:1) to receive either the standard of care Penicillin or Cefixime. During the study, participants will visit the clinic up to 5 times; at baseline visit, at 3, 6, 12 months after treatment initiation. Participants of the cefixime group will be required to visit the clinic 14 days after treatment initiation. In each visit, participants will be asked about current symptoms and do laboratory tests for syphilis (RPR). Subjects who have a 4-fold decrease (from study entry RPR) in RPR titers from baseline at 6 months will be considered a positive treatment response.
The study aims to evaluate the efficacy of linezolid for the treatment of syphilis.
This study aims to evaluate the efficacy of cefixime compared to benzathine penicillin G in the treatment of syphilis.
The goal of this clinical trial is to learn if doxycycline taken as 200mg daily for 14 days is effective to treat early stage syphilis. This is different from how doxycycline is typically used for syphilis because the full doxycycline dose will be taken at the same time of day, rather than split up into a twice daily regimen. Lab data support that taking the medication as a single daily dose should be effective as treatment, but it has not been studied clinically. The main question this study aims to answer is: Is doxycycline taken as a single daily dose of 200mg for 14 days an effective treatment for early syphilis based on a combined outcome of clinical improvement and blood test improvement? Participants will: 1. Take doxycycline 200mg daily for 14 days 2. Submit oral and rectal swabs that test for syphilis bacteria every other day for 2 weeks, returned by mail 3. Complete 2 brief online surveys over the first 2 weeks 4. Return to the clinic for an interview and blood draw every 3 months for a maximum of 3 study visits, including the first visit The investigators will compare the percentage of participants in the study who have response to treatment by 6 months to that of persons who have received standard (CDC-recommended) regimens. To do this, the investigators will calculate response percentage estimates following a shot of long-acting penicillin or 14 days of doxycycline 100mg twice daily from 60-person samples from the sexual health program's records.
