Can a cancer drug reboot the immune system in chronic fatigue syndrome?

NCT ID NCT07724834

First seen Jul 24, 2026 · Last updated Jul 24, 2026

Summary

This trial tests whether inebilizumab, an antibody that wipes out certain immune cells called B cells, can improve physical function in adults with ME/CFS that started after an infection. Participants receive three infusions over six months, and the study measures changes in mobility, fatigue, and daily activity. The goal is to see if targeting the immune system can ease the disabling symptoms of post-infection ME/CFS.

What this could mean

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

Active substance
inebilizumab, an anti-CD19 monoclonal antibody that depletes B cells
What this could lead to
If it works, this could point toward a targeted treatment for the underlying immune dysfunction in post-infection ME/CFS.
What could go wrong
This is a small, early-phase trial with only 38 participants. The treatment depletes B cells, which can increase infection risk, and it is unknown whether the benefits seen in a pre-selected group will apply to a broader population.
