In the event the Sponsor electively closes Cohorts 2-4 prior to completion, patients with CLL/SLL who are ineligible to participate in or unable to access late phase studies of pirtobrutinib may be eligible to enroll in this cohort Diffuse large B-cell lymphoma (DLBCL) is excluded. MCL without prior BTK inhibitor treatment is excluded. Patients enrolling to Cohort 7 must have received one or more prior therapies or have no available approved therapy with demonstrated clinical benefit with the exception of untreated Richter's transformation, which is allowed.
