New drug could keep rare blood disease in check

NCT ID NCT06831058

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tests efgartigimod, a drug that lowers harmful antibodies, in 15 adults with immune-mediated thrombotic thrombocytopenic purpura (iTTP), a rare and life-threatening blood disorder. Participants receive weekly infusions for 8 weeks, then are monitored for another 8 weeks. The goal is to see if the drug can safely raise ADAMTS13 activity and prevent relapses better than the current standard, rituximab.

What this could mean

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

Active substance
efgartigimod
What this could lead to
If it works, this could point toward a safer maintenance therapy to prevent relapses of iTTP without long-term immune suppression.
What could go wrong
This is a very small pilot study (15 people) comparing results to past patients, not a controlled trial. The effect may be temporary, and the drug may not prevent relapses better than existing treatments.
