Details and patient eligibility

About

This is a single arm, multi-center study to evaluate the efficacy and safety of orelabrutinib for Chronic lymphocytic lymphoma(CLL)/small lymphocytic lymphoma (SLL) patients who are slowly responding to Ibrutinib switched to Orelabrutinib.

Full description

The eligible CLL/SLL patients who are slowly responding to Ibrutinib will be switched to Orelabrutinib treatment. The patients will receive Orelabrutinib 150mg oral daily (28 days/cycle) for up to 2 year or until disease progression, intolerable toxicity, death, informed consent withdrawal or lost of follow up (whichever occurs first).
