Study Arms (2)
Dose Escalation
EXPERIMENTALDose escalation (3+3 design) and determination of MTD and DLTs CLL/SLL or B-cell NHL patients will self-administer docirbrutinib oral tablet at multiple dose levels twice daily for 24 cycles (1 cycle = 28 days).
Dose Expansion
EXPERIMENTALCohort 1: CLL/SLL patients, Cohort 2: B-cell NHL patients, Cohort 3: CLL/SLL or B-cell NHL patients with prior treatment with pirtobrutinib (Jaypirca) for an approved indication Patients will self-administer docirbrutinib oral tablet for 24 cycles (1 cycle = 28 days). Dose levels will be determined based on the result of dose escalation part.
