NCT ID NCT07555431

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial compares the drug dolutegravir alone versus dolutegravir combined with tenofovir in 146 adults with HTLV-1 infection and related symptoms. The main goal is to see if the combination lowers the virus level more effectively and improves pain, spasticity, and muscle strength over 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

dolutegravir and tenofovir disoproxil fumarate

What this could lead to

If successful, this could point toward a more effective treatment to lower the virus and ease symptoms like pain and muscle weakness in people with HTLV-1.

What could go wrong

This is a small, early-phase trial (Phase 2) with only 146 participants. The combination has not been tested before, so it may not work better than dolutegravir alone, and side effects are not yet well understood.
