Interventions and Outcome Measures

Arms

experimental: Dose Escalation

Dose 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).

experimental: Dose Expansion

Cohort 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.

Interventions

Docirbrutinib

oral tablet, twice daily

Primary outcome measure

  • Number of patients with dose limiting toxicities (DLTs) and determination of maximum tolerated dose (MTD) [ Time Frame: Up to 24 cycles (1 cycle = 28 days) ]
  • Overall response rate (ORR) as assessed by investigator [ Time Frame: Up to 24 cycles (1 cycle = 28 days) ]
