Could Long-Acting HIV shots save lives and money in thailand?
NCT ID NCT05774548
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at whether long-acting antiretroviral drugs for HIV prevention (PrEP) are effective and affordable for key populations in Thailand, including men who have sex with men and transgender women. Researchers will survey over 10,000 people about their preferences, analyze clinic data, and use computer models to estimate the impact and cost. The goal is to help decide if long-acting PrEP should be offered more widely.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could show whether long-acting HIV prevention drugs are worth using widely in Thailand, helping to reduce new HIV infections.
- What could go wrong
- This is an observational and modeling study, not a drug trial. It cannot prove that long-acting PrEP works better than current options, and real-world results may differ from the models.
