Summary

This trial studies the effectiveness of acalabrutinib in treating patients with chronic graft-versus-host disease.

Who is the study for?

This trial is for adults over 18 with moderate to severe chronic graft versus host disease (GVHD) after a stem cell transplant. They must understand the study, be able to swallow capsules, and have a performance status indicating they can carry out daily activities. Women who can bear children and men must use effective contraception. People with uncontrolled heart or blood conditions, recent major surgery, certain infections or cancers, or those on specific medications cannot join.

What is being tested?

The trial is testing Acalabrutinib's effectiveness in treating chronic GVHD following stem cell transplantation. It's a phase II study where participants will also complete questionnaires about their health status.

What are the potential side effects?

Potential side effects of Acalabrutinib may include bleeding problems, increased risk of infection due to immune system effects, possible liver issues indicated by changes in blood tests, and possibly other organ-related inflammation.
