Clinical trials

This study evaluates the pre-implementation phase of a host-led harm reduction model for men who have sex with men (MSM) engaging in chemsex in Bangkok, Thailand, focusing on understanding harms, contexts, and needs to develop a tailored intervention.

This study evaluates a comprehensive transgender-tailored harm reduction service for transgender women, transgender men, and non-binary individuals engaging in chemsex or substance use in Thailand, focusing on PrEP uptake, HIV/STI outcomes, mental health, and socio-legal impacts.

The study evaluates the integration of a sexual pleasure-based approach into harm reduction services for MSM and transgender persons engaging in chemsex or substance use in Thailand, using the "Pleasuremeter" tool to improve sexual health and related outcomes.

The study is a pre-implementation cross-sectional study exploring chemsex behaviors among transgender persons and gathering perspectives from multiple stakeholders to inform the development of transgender-tailored harm reduction services.

This study aims to develop and evaluate a multi-component mHealth intervention (mHC and FRESH) to reduce HIV-related and intersectional stigma and improve PrEP use among HIV-negative young transgender women (TGW) in Thailand.

This protocol describes a 20-year prospective cohort study, gathering behavioral and psychosocial information on clients who access services of the Institute of HIV Research and Innovation (IHRI) and the Thai Red Cross AIDS Research Centre through the Thai Red Cross Anonymous Clinic, the Thai Red Cross Mobile Clinics, Affiliated Health Clinics, The gender and immunity clinic and Pribta Tangerine Polyclinic. Services provided through these sites include VCT, STD screening and treatment, anal and cervical Pap smears, general health checkups, sexual health education, and sexual health communication, gender-affirmative hormone therapy (GAHT) and risk-reduction via web boards and chat rooms. Behavioral and psychosocial information will be collected using validated questionnaires and from data collection forms routinely used when providing services in different service sites of IHRI and the TRC-ARC. The information will be collected anonymously at baseline and at follow-up visits, according to type of services each client receives. Clients at the Thai Red Cross Anonymous Clinic, Thai Red Cross Mobile Health Clinics, Affiliated Health Clinics and Pribta Tangerine Polyclinic will be given an identification number. Qualitative methods, including focus group discussions (FGD) and in-depth interviews (IDI) will be conducted with clients and healthcare providers to examine the facilitators, barriers, feasibility and acceptability of service implementation.

CLYMAX is a two-phase observational study that assess multiple aspects of chemsex and young men who have sex with men (YMSM). Phase I of the study (CLYMAX,IRB No. 0695/65) was a cross-sectional descriptive study using a mixed methods data collection (focusing on qualitative data collection) assessing multiple aspects of chemsex, including the patterns of chemsex use and the perspectives on factors influencing chemsex initiation/discontinuation, effects on physical health, mental health and social outcomes, and the necessary services for a comprehensive chemsex clinic among YMSM; and the acceptability and feasibility of developing a comprehensive chemsex clinic from the perspective of YMSM, their family members or peers, and clinic staff. This phase II study (CLYMAX-2) will be a prospective cohort study using a quantitative data collection exploring the effectiveness of the implementation strategy of harm reduction models and consist of a larger number of YMSM, important baseline and follow-up information on multiple aspects of physical, psychological, and social harms.

This study will have three components: 1. Discrete choice experiments 2. Analysis of routine service data 3. Impact and cost-effectiveness analyses using results from 1 and 2
