A Phase 2, Open-Label, Randomized Study Evaluating the Efficacy and Safety of 3 Doses of Pirtobrutinib in Participants With Relapsed or Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Who Previously Received Treatment With a Covalent Bruton Tyrosine Kinase Inhibitor

Description

The main purpose of this study is to assess the efficacy and safety of 3 dose levels of Pirtobrutinib in participants with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), who have received 1-3 lines of treatment including a covalent Bruton tyrosine kinase (BTK) inhibitor. The study is expected to last approximately 3 years.

Trial Eligibility

Exclusion Criteria: * Have received prior treatment with a BTK degrader and a noncovalent BTK inhibitor * Have a history of greater than or equal to (\>=) Grade 3 bleeding due to treatment with a BTK inhibitor * Have known or suspected Richter's transformation * Have known or suspected history of central nervous system involvement by CLL/SLL * Previous or concurrent cancer distinct from CLL/SLL within 3 years before randomization. Exceptions may occur with documented sponsor approval. Examples include: * nonmelanoma skin cancer or lentigo maligna melanoma * cervical carcinoma in situ * localized prostate cancer undergoing active surveillance, and * localized (for example, lymph node negative) breast cancer with no evidence of active disease present for more than 3 years. Individual may be receiving adjuvant hormonal therapy
