Cohort 1: Emavusertib and ZanubrutinibEXPERIMENTALParticipants in Cohort 1 include CLL participants who have been on zanubrutinib for at least 12 months and are currently in a partial response (PR) or partial response with lymphocytosis (PR-L) and measurable residual disease positive (MRD+). In Part A, participants will receive one of two doses of emavusertib twice daily (BID) and an approved dose of zanubrutinib per label. In Part B, additional participants will be enrolled in an expansion if pre-defined criteria for Part A are met. Participants will receive one of two doses of emavusertib BID and an approved dose of zanubrutinib per label.
Cohort 2: Emavusertib and ZanubrutinibEXPERIMENTALParticipants in Cohort 2 include relapsed CLL participants who have directly progressed on zanubrutinib after a confirmed response (PR or better lasting 6 months or longer). In Part A, participants will receive one of two doses of emavusertib BID and an approved dose of zanubrutinib per label. In Part B, additional participants will be enrolled in an expansion if pre-defined criteria for Part A are met. Participants will receive one of two doses of emavusertib BID and an approved dose of zanubrutinib per label.
