Sexually Transmitted Infections clinical trials at UCSF

3 in progress, 1 open to eligible people

Sexually transmitted infections are illnesses spread through sexual activity. UCSF is testing a method called Doxy-PEP to see if it can reduce the number of these infections. The study is important because the number of these infections is increasing worldwide.

  • Directly Observed Therapy Study to Interpret Clinical Trials of Doxy-PEP

    open to eligible people ages 18 years and up

    Rates of bacterial sexually transmitted infections (STIs) are rising globally, demanding innovative interventions beyond the scope of current efforts to prevent STIs. The United States Doxycycline Post-exposure Prophylaxis (DoxyPEP) Study has demonstrated the efficacy of doxycycline post-exposure prophylaxis (PEP) among men who have sex with men and transgender women; but puzzlingly, doxycycline PEP was found ineffective in cisgender women in the Kenyan doxycycline Post-Exposure Prophylaxis (dPEP) study, with preliminary data suggesting the low medication adherence may explain the null result. By study end, the investigators will have developed adherence measurement methods for doxycycline in hair, blood, and urine, and will use these techniques to help interpret the Kenyan dPEP study, and to examine the relative performance of these methods within the United States DoxyPEP trial, establishing adherence metrics for current and future rollout studies of doxycycline post-exposure prophylaxis

  • Heavy Alcohol Use Consumption With Kudzu

    Sorry, in progress, not accepting new patients

    Drinking multiple alcoholic drinks on a single occasion (binge drinking), has many negative health risks but interventions to address this behavior remain limited. This double-blind, placebo-controlled randomized clinical trial will test whether kudzu, an herbal supplement, can reduce heavy alcohol use and alcohol-associated sexual behaviors among sexually-active, binge-drinking individuals at high risk for HIV infection.

  • Rigorous Evaluation of Yes and Know, a Fully Virtual Sexual Health and Well-Being Intervention for Youth

    Sorry, not yet accepting patients

    This study is a 2-arm cluster randomized controlled trial with approximately 1,200 youth aged 14-19 years to assess the effectiveness of Yes and Know, a sexual health education program. To be eligible, participants must be 14-19 years old and English-speaking. Those in the treatment arm will receive Yes and Know, a synchronous virtual program delivered over multiple sessions totaling nine hours, along with asynchronous online activities and resources. Those in the control arm will receive a similarly structured program focused on nutrition education. Participants will complete brief online surveys at baseline and at 3 and 12 months after the synchronous sessions. The study will assess the program's effectiveness in reducing the prevalence of unprotected sex among youth and improving short-term outcomes, such as knowledge of reproductive health and healthy relationships, self-efficacy, and the use of reproductive health services.
