Could a simpler Two-Drug HIV regimen be just as effective as three?
NCT ID NCT07678268
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This trial tests whether a two-drug combination (darunavir/cobicistat plus lamivudine) works as well as a standard three-drug combination (darunavir/cobicistat plus tenofovir alafenamide/emtricitabine) in people with HIV whose virus is already suppressed. The study involves 78 adult men in Mexico who have had undetectable HIV levels for at least 48 weeks. Researchers will compare how well each regimen maintains viral suppression and monitor safety over 24 and 48 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Darunavir/Cobicistat plus Lamivudine
- What this could lead to
- If successful, this could show that a simpler two-drug HIV regimen is as effective as the standard three-drug approach, potentially reducing pill burden and side effects.
- What could go wrong
- This is a small pilot study with only 78 participants, all men, so results may not apply to everyone. The two-drug regimen might not suppress the virus as well as the three-drug combination.
