A drug used alone or with other drugs to treat adults with chronic lymphocytic leukemia, small lymphocytic lymphoma, or Waldenstrom macroglobulinemia (a type of non-Hodgkin lymphoma). It is also used to treat adults and children aged 1 year and older with chronic graft versus host disease. It is also being studied in the treatment of other types of cancer. Ibrutinib blocks a protein called BTK, which may help keep cancer cells from growing. It may also lower the body’s immune response. Ibrutinib is a type of tyrosine kinase inhibitor.
