Could a Two-Drug HIV pill work for TB patients?

NCT ID NCT06497465

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests whether a two-drug HIV regimen (dolutegravir plus lamivudine) works as well as the standard three-drug regimen in people who also have tuberculosis and are on TB treatment. About 150 participants who have never taken HIV medication will be randomly assigned to one of three groups. The goal is to see if the simpler regimen can control HIV just as effectively while reducing the number of pills and potential side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Dolutegravir and lamivudine (DTG/3TC)
What this could lead to
If successful, this could offer a simpler, lower-toxicity HIV treatment option for people also being treated for tuberculosis.
What could go wrong
This is a mid-stage trial with only 150 participants. The dual therapy may not suppress HIV as well as the standard three-drug regimen, and drug interactions with TB meds remain a concern.
