Could a cancer drug tame a blood disorder?

NCT ID NCT04657094

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

Summary

This phase 2 trial tests the drug acalabrutinib in people with chronic lymphocytic leukemia (CLL) who also have a blood condition called autoimmune hemolytic anemia (AIHA) that has come back or not responded to treatment. The study aims to see if acalabrutinib can control the anemia by blocking certain enzymes. Only 4 participants were enrolled, making this a very early look at the drug's potential.

Active substance
acalabrutinib
What this could lead to
If successful, this could offer a new treatment option for patients with autoimmune hemolytic anemia that hasn't responded to standard therapy.
What could go wrong
This is a very small early-phase trial (only 4 participants), so results may not apply to larger groups. The drug may not work or could have side effects.
