What was measured
ORR is defined as the percentage of participants with a complete response (CR) / complete response with incomplete bone marrow recovery (CRi), nodular partial response (nPR) or partial response (PR) per investigator assessment. Disease response was assessed in accordance with the 2008 criteria of the International Workshop on CLL (IWCLL), with modification for treatment-related lymphocytosis in participants with CLL and in accordance with the Lugano classification in participants with SLL.

Groups in this outcome
Zanubrutinib
Participants received 160 mg zanubrutinib orally twice daily until disease progression, intolerable toxicity, initiation of alternative anticancer therapy, investigator/Sponsor decision, need for prohibited medication, study withdrawal, or pregnancy.
Ibrutinib
Participants received ibrutinib 420 mg orally once daily until disease progression, intolerable toxicity, initiation of alternative anticancer therapy, investigator/Sponsor decision, need for prohibited medication, study withdrawal, or pregnancy.
