ClinicaliQ Trial Snapshot
  • A Study of NX-5948 in Adults With CLL/SLL Previously Treated With a Bruton’s Tyrosine Kinase Inhibitor and a B-cell Lymphoma-2 Inhibitor (DAYBreak CLL-201) — Recruiting • Phase II • Oncology • NCT07221500.
  • NX-5948, a novel protein degradation agent, is being tested as a potential treatment for patients with relapsed/refractory CLL/SLL who have exhausted standard therapeutic options (prior BTK inhibitors and BCL-2 inhibitors).
  • Eligible patients must have documented disease progression after exposure to both BTK inhibitors and BCL-2 inhibitors, representing a heavily pre-treated population with limited remaining treatment alternatives.

What This Trial Is Studying

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.

Eligibility Snapshot
  • : * 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 therapy or in combination; a line of therapy is considered 2 or more consecutive cycles of a systemic anti-CLL/SLL regimen * Participants with SLL must have 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
