Active clinical trials for "Sexually Transmitted Diseases"

A multicenter, randomized, parallel-group, placebo-controlled, double-blind, Phase 1/2a clinical study to investigate the safety, tolerability, immunogenicity and exploratory efficacy of a vaccine regimen consisting of an Ad26.Mos4.HIV prime and a boost with Modified Vaccinia Ankara (MVA)-BN-HIV in combination with broadly neutralizing antibodies (bNAb) PGT121, PGDM1400, and VRC07-523LS in human immunodeficiency virus type 1 (HIV-1)-infected study participants on suppressive anti-retroviral therapy (ART).

This study will test the effectiveness, implementation outcomes, and cost effectiveness of a community-tailored, harm reduction kiosk in reducing HIV, hepatitis C, and overdose risk behavior in rural Appalachia. The proposed project will take place in two counties in Appalachian Kentucky, an epicenter for the intertwined national crises of injection drug use, overdoses, and hepatitis C.

This digital couples-based HIV/STI prevention intervention project will determine preliminary efficacy to improve uptake of evidence-based strategies and a tailored prevention plan among cisgender male couples who are in a relationship (defined as greater than 3 months or more).

The study will recruit 120 Black men who have sex with men (BMSM) from the local area, New Orleans. The main purpose of this research study is to test the effect of a new smartphone application, "PCheck," on reducing the incidence of STIs, compared to routine care through the LSU-Crescent Care Sexual Health/PrEP Clinic.

The proposed study involves conducting a larger-scale study exploring Game Plan's effects among MSM in the real-world, alongside innovative approaches for expanding HIV testing. Using a hybrid 1 effectiveness-implementation approach, the investigators will recruit up to 360 high-risk, heavy drinking MSM online from several high-incidence areas in the US to participate in a program providing home-based HIV/STI self-tests in the mail at regular intervals over a year (baseline, 6 months, 12 months). Participants will be randomly assigned to receive access to either (1) a 24-hour helpline for counseling/referrals, or (2) the helpline plus Game Plan. Investigators will test whether those who use Game Plan show lower rates of heavy drinking, any STIs, and high-risk CAS events compared to those receiving access to the helpline alone.

Thia is a multi-site, randomised 2-period cross-over trial comparing five uses of a 61 mm width synthetic nitrile male condom with five uses of a 61 mm width standard latex male condom.

This is a multi-site, randomised 3-period cross-over trial evaluating the functional performance of two synthetic nitrile male condoms against a control latex male condom.

Objectives: Efficacy of a meningococcal vaccine against Neisseria gonorrhoea (NG) infection among men who have sex with men (MSM). Design: Parallel randomised double-blind placebo-controlled trial. Setting: A teaching hospital in Hong Kong. Participants: 150 adult MSM at risk of gonorrhoea infection (condomless sex with more than one man within the last six months, history of sexually transmitted infection [STI] diagnosis, inclination to have condomless sex, and other PrEP-eligible criteria) would be recruited into the trial, with half allocated to intervention and control group each. Intervention: Intervention and control group would receive, one month apart, two doses of meningococcal vaccine and normal saline, respectively. Main outcome measures: Safety and efficacy of vaccine against gonorrhoea (time to first gonorrhoea infection and incidence), and behavioural change after vaccination. Expected results: NG incidences in two groups would be compared. Efficacy of vaccine against gonorrhoea would be determined after controlling confounding variables. Characteristics of participants with incident NG would be distinguished from those without incident infections. Change of frequency of sexual activities and networking would be noted. Implications: Strategies on STI screening and vaccination could be informed. Reduced STI burden post-vaccination could be measured with surveillance system.

The aim of this first time in human proof of concept (FTiH-PoC) study is to evaluate safety and reactogenicity, to demonstrate efficacy and to explore immunogenicity of GlaxoSmithKline's (GSK) Neisseria gonorrhoeae generalized modules for membrane antigens (GMMA) (NgG) investigational vaccine compared to placebo (saline).

The goal of this study is to evaluate the impact of SafeSpace Sexual Health App, an innovative sexual health promotion program focused on reducing sexual risk factors and promoting sexual and reproductive health and wellbeing among young people assigned female or intersex at birth, particularly Black and/or Latine youth, LGBTQ+ youth, youth in states with high teen birth rates and youth who live in rural communities. This study utilizes a two-arm randomized control trial design to measure impacts of receiving the SafeSpace Sexual Health program compared to receiving a similar-length control app program, SafeSpace General Health that focuses on general health. We will ask participants to: Keep the SafeSpace app downloaded to their device and visit the app regularly over the course of 10 weeks. Provide contact information. Receive and open app push notifications for 10 weeks (up to 3 per week). Complete 3 online surveys over a year: baseline, short-term follow-up (10 weeks after baseline), and long-term follow up (9 months after short-term follow-up). Receive occasional text messages from the study team.
