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

Summary

This study tests an experimental drug called rilzabrutinib in 22 adults with warm autoimmune hemolytic anemia (wAIHA), a condition where the immune system attacks red blood cells. Participants take the drug daily for up to 24 weeks, with an option to continue longer. The main goal is to see if it raises hemoglobin levels and reduces the need for blood transfusions or rescue medications.

What this could mean

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

Active substance

rilzabrutinib (a drug taken as a tablet by mouth)

What this could lead to

If it works, this could offer a new oral treatment option for people with warm autoimmune hemolytic anemia who have not responded well to steroids.

What could go wrong

This is a small, early-phase (Phase 2) study with only 22 participants, so results may not apply to everyone. The drug may not work as hoped or could have side effects.
