Active clinical trials for "Sexually Transmitted Diseases"

Pre-Exposure Prophylaxis (PrEP) is a biomedical strategy consisting of the use of antiretroviral therapy by HIV-seronegative people at high risk of acquiring HIV, to prevent the infection. Many controlled and randomized clinical trials, as well as implementation projects have shown that the use of tenofovir disoproxil (TDF) and emtricitabine (FTC) is both safe and effective in the prevention of HIV infection. However, the administrative situation of PrEP in Spain is anomalous. Unlike in some European countries, PrEP is not available within the National Health System (SNS), although being available for the treatment of HIV infection. In Spain the fixed-dose combination of FTC / TDF is for hospital use only, which requires prescription by HIV specialists exclusively and restricts its dispensation to pharmacy services within the hospital. This limitation in access and the knowledge of its prevention capacity of PrEP by vulnerable population has led them to obtain "generic FTC / TDF" outside the standardized health care system. According to a survey conducted in Europe to characterize MSM users of PrEP carried out in 2016, 5% of PrEP users had acquired it on their own. Of these 70% stated they were not included in any regular follow-up program while using the medication. Despite the growing demand, there are no health programs (including information, counseling, systematic screening for sexually transmissible infection (STI), etc.) aimed at meeting the health care needs of those who already use or wish to use PrEP, neither by public nor private healthcare providers. This type of service is especially necessary when considering that, among PrEP users, one may have already an established HIV infection, theoretical increase of other STI and a lack of monitoring kidney functions.. BCN Checkpoint is a community center since 2006 for the detection of HIV and other STI aimed at gay men, other men who have sex with men (MSM) and transgender women (TGW), which has shown high efficiency in HIV screening and fast referral to standard HIV care and treatment.. In 2017 the organization opened BCN PrEP·Point, a community centre with the goal to provide information, to conduct clinical trials and clinical monitoring of informal PrEP use. For this reason, it is presented here the protocol of the SeguiPrEP study, prospective, longitudinal study of health care in the community environment, to MSM and TGW, users of informal PrEP, based on point-of-care testing technology.

The purpose of this study is to test the efficacy of Our Family Our Future, an integrated intervention for preventing HIV and depression onset among adolescents.

The purpose of this study is to examine whether treatment of pregnant Malawian women with repeated doses of sulfadoxine-pyrimethamine and azithromycin antibiotics will prevent preterm deliveries and result in other health benefits both for the mother and the foetus/newborn.

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.

This study will evaluate whether EVO100 vaginal gel prevents the sexual transmission of CT and GC infection

The current study extends the study team's earlier efforts described in ClinicalTrail ID#: NCT04070287 and NCT03874663. The I-TEST (Innovative Tools to Expand Youth-friendly HIV Self-Testing) study known locally as the 4 Youth by Youth project, sought to develop and evaluate novel youth-friendly HIVST services in Nigeria using open challenges and apprenticeship training informed by a participatory learning collaborative model. The study thus aims to reach young Nigerians that remain undiagnosed for HIV and to facilitate linkage and retention in preventive services (includes STI testing/treatment, PrEP referral, condom use).

To achieve an AIDS-free generation, there is a critical need for programs which go beyond individual-level behavior change to reduce HIV and STI infections among adolescent girls and young women in sub-Saharan Africa. Informed, Motivated, Aware, and Responsible Adolescents and Adults (IMARA) is an evidence-based HIV-prevention intervention for adolescent girls and young women (AGYW) and their female caregivers, which has been adapted for a South African audience. The study will test whether AGYW receiving IMARA will have fewer sexually-transmitted infections (STI) and greater acceptance of HIV testing and counseling (HTC) and pre-exposure prophylaxis (PrEP) at 6-month follow-up compared to AGYW assigned to the health-promotion control intervention.

Oral pre-exposure prophylaxis (PrEP) is a recommended component of combination HIV prevention and its availability is rising through demonstration projects and full-scale national programs. In sub-Saharan Africa, young women are a priority population for HIV prevention and targeted to initiate PrEP, given their high HIV incidence rates and promising success from a strategy that can be used without the engagement of male partners. A key question in the field is whether young women using PrEP have ongoing HIV risk and adhere to PrEP sufficiently to have protection from HIV when they have condomless sex with HIV-infected partners. The only true way to know whether a heterosexual woman is sexually exposed to HIV or has a partner with high HIV risk is to test for HIV and STIs in her male partner(s) and quantify HIV viral levels, if any are detected. Yet engaging men in clinic-based HIV testing is challenging. More recent efforts have focused on using HIV self-testing kits to respond to demands on men's time and reluctance to seeking preventive healthcare. The availability of PrEP also provides a new incentive for men to test. By leveraging an ongoing study of bone health with concurrent use of PrEP and injectable DMPA (often known as Depo Provera® or depot medroxyprogesterone acetate), we have opportunity to engage a new cohort of young men and objectively measure HIV and common STIs in these young men and link the results to women's use of PrEP. The primary objective of this study is to determine whether young women's adherence to PrEP aligns with the HIV status and risk of their male partners. To address its primary objectives, this study will leverage: 1) an ongoing study among young women and 2) a novel cohort of young men who are current sexual partners of the young women in the ongoing study to objectively measure PrEP use, HIV, and HIV factors related to HIV risk. This study will provide a framework for understanding how and when young women and men decide to take PrEP, estimate the proportion of women that are benefitting from HIV protection when they have male partners with or at high risk of acquiring HIV, and provide a novel opportunity to engage young men in PrEP delivery and as supporters of women's PrEP use.

Syphilis is a sexually transmitted infection (STI) disproportionately affecting gay, bisexual and other men who have sex with men (gbMSM), with the potential for significant sequelae - particularly in those who are Human Immunodeficiency Virus (HIV)-positive. Rising rates of this STI have prompted a search for novel prevention solutions. A recent pilot study of daily doxycycline prophylaxis demonstrated promise as a novel STI prevention tool. This innovative approach to STI prevention has solid clinical precedent, both from the HIV pre-exposure prophylaxis (PrEP) literature, as well as doxycycline's use as prophylaxis for other infections. The overarching goal of this project is to determine whether the daily use of doxycycline is an efficacious and acceptable intervention for syphilis prevention in high-risk, HIV-positive gbMSM.

The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It has been designed to find out if communities that were trained to use the CTC system improved public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that did not use this approach. The primary purpose of the current continuation study is to investigate whether CTC has long-term effects on substance use, antisocial behavior, and violence, as well as secondary effects on educational attainment, mental health, and sexual risk behavior in young adults at ages 26 and 28. The continuation study also examines (a) how the interaction of social, normative, and legal marijuana contexts creates variation in the permissiveness of individuals' marijuana environments from late childhood to young adulthood and (b) whether, when, and for whom permissive marijuana environments increase marijuana and ATOD use and misuse from age 11 to 28 and interfere with the adoption of adult roles.
