A Single-arm, Phase 2, Open-label, Multicenter Study to Evaluate NX-5948 in Adults With Relapsed/Refractory (R/R) Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL) Previously Exposed to a Bruton's Tyrosine Kinase Inhibitor (BTKi) and a B-cell Lymphoma-2 Inhibitor (BCL-2i)
This is a study for patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have previously received treatment with a BTK inhibitor (covalent and non-covalent) and a BCL-2 inhibitor. The main purpose of this study is to test if NX-5948 (bexobrutideg) works to treat patients with CLL/SLL. Participation could last up to 5 years, and possibly longer, if the disease does not progress.
• Age: ≥ 18 years
• Confirmed relapsed/refractory CLL/SLL that meets iwCLL criteria for diagnosis and systemic treatment
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
• Must have received a covalent BTK inhibitor (BTKi), a non-covalent BTKi, and a BCL-2 inhibitor either in separate lines of treatment or in combination
• Measurable disease by radiographic assessment
• Adequate organ and bone marrow function
• Must sign an informed consent form indicating that he or she understands the purpose of the procedures required for the study and is willing to participate
