Gonorrhea clinical trials at University of California Health
4 in progress, 3 open to eligible people
Antibacterial Mouthwash for Pharyngeal Gonorrhea Prevention
open to eligible males ages 18-45
This study aims to determine acceptability and preliminary efficacy of daily use of an antibacterial mouthwash as compared to a placebo mouthwash in reducing the incidence of pharyngeal gonorrhea among a cohort of HIV-positive and high risk HIV-negative men. Investigators plan to test the following hypotheses: 1. Participants will maintain a high level of adherence and satisfaction with daily mouthwash use. Furthermore, the investigators hypothesize that barriers to adherence will include structural factors such as unstable housing and individual level factors such as substance use. 2. Participants receiving the antibacterial mouthwash will have a lower incidence of pharyngeal gonorrhea as compared to participants receiving the placebo mouthwash. Furthermore, the investigators hypothesize that these reductions will remain even after adjusting for other factors such as HIV-status and substance use.

Inflammation in Methamphetamine and STIs (IMSTI)
open to eligible males ages 18 years and up
This clinical trial aims to investigate the effects of a decline in methamphetamine use on rectal inflammatory cytokine levels, substance use contexts, and HIV/STI risk behavior. This clinical trial also seeks to evaluate joint effects of methamphetamine use and rectal gonorrhea/chlamydia infection on rectal inflammatory cytokine levels. The proposed trial will consist of 40 MSM, half with rectal gonorrhea/chlamydia infection at enrollment (n=20), with methamphetamine use disorder that will receive contingency management for methamphetamine reduction. Following baseline measurement, participants will be observed over the course of 8 weeks, where participants will complete behavioral surveys, provide urine for drug testing, and rectal samples for measurement of rectal inflammatory cytokine levels.

Meningococcal Group B Vaccine rMenB+OMV NZ (Bexsero) to Prevent Gonococcal Infection
open to eligible people ages 18-50
This is a Phase II, randomized, observer-blind, placebo-controlled, multi-site trial of the FDA licensed rMenB+OMV NZ vaccine, Bexsero. The targeted study population is men and women 18-50 years of age who are disproportionately vulnerable to N. gonorrhoeae infection. Approximately 2,200 participants are expected to be enrolled to achieve at least 202 evaluable participants. Data will be collected in an observer-blind manner. Study product recipients and study staff responsible for the evaluation of any study endpoint will be unaware of whether Bexsero or placebo were administered. The duration of the study for participants who are enrolled and randomized will be approximately 16 months. Study participation is expected to be completed in approximately 36 months. The primary objective of the study is to demonstrate efficacy of Bexsero in prevention of urogenital and/or anorectal gonococcal infection.

Doxycycline Post-exposure Prophylaxis to Reduce Sexually Transmitted Infections in PrEP Users and HIV-infected Men Who Have Sex With Men
Sorry, in progress, not accepting new patients
The purpose of this study is to understand if taking an antibiotic called doxycycline by mouth as soon as possible after sexual contact without a condom can reduce the risk of sexually transmitted infections (STIs), including gonorrhea, chlamydia and syphilis. The study will also look at the safety of doxycycline PEP and the impact that PEP may have on the bacteria that cause STIs as well as on bacteria that normally live on the body. While doxycycline is approved by the Food and Drug Administration (FDA), taking doxycycline immediately after sexual contact to prevent infection is investigational and is not approved by the FDA for this use. Participants will take part in the study for 1 year.
