This is an open-label, multi-center Phase 1/2 study of oral LOXO-305 (pirtobrutinib) in
patients with CLL/SLL and NHL who have failed or are intolerant to standard of care.
This study includes 3 parts: Phase 1 (pirtobrutinib monotherapy dose escalation and dose
expansion), Phase 1b (pirtobrutinib combination therapy dose expansion), and Phase 2
(pirtobrutinib monotherapy dose expansion). In Phase 1, patients will be enrolled using an
accelerated titration design. The starting dose of pirtobrutinib in oral tablet form is 25
mg/day (e.g., 25 mg once daily [QD]). Once the MTD and/or RP2D is identified in Phase 1 dose
escalation, enrollment will continue to Phase 1 dose expansion and can commence to Phase 1b
(Arms A and B). For Phase 2, patients will be enrolled to one of seven Phase 2 dose expansion
cohorts depending on tumor histology and prior treatment history. Cycle length will be 28
