HIV drug resistance showdown: stay or switch?
NCT ID NCT06747507
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This trial looks at what to do when the HIV virus becomes resistant to the drug dolutegravir. It compares staying on dolutegravir versus switching to another drug combination (darunavir/ritonavir) to see which better lowers the virus level. About 392 people with HIV and specific resistance mutations will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dolutegravir pill or darunavir+ritonavir pill
- What this could lead to
- If it works, this could show the best way to manage HIV when the virus becomes resistant to dolutegravir, helping more people achieve viral suppression.
- What could go wrong
- This is a Phase 3 trial, but it only includes people with specific resistance mutations, so results may not apply to everyone. There is also a risk that neither strategy works well.
