Official Title ICMJE | A Phase 1, Dose Escalation, and Cohort Expansion Study Evaluating NX-5948, a Bruton's Tyrosine Kinase (BTK) Degrader, in Adults With Relapsed/Refractory B-cell Malignancies | ||||||
Brief Summary | This is a first-in-human Phase 1a/1b multicenter, open-label study designed to evaluate the safety and anti-cancer activity of NX-5948 in patients with advanced B-cell malignancies. | ||||||
Detailed Description | Phase 1a is a dose escalation to evaluate the safety and tolerability of NX-5948 in adult patients with relapsed/refractory (R/R) B cell malignancies who have received at least 2 prior lines of therapy, or at least 1 prior line of therapy for Primary Central Nervous System Lymphoma (PCNSL), and for whom no other therapies are known to provide clinical benefit. Indications include: Chronic Lymphocytic Leukemia (CLL), Small Lymphocytic Lymphoma (SLL), Diffuse Large B-cell Lymphoma (DLBCL), Mantle Cell Lymphoma (MCL), Waldenstrom Macroglobulinemia (WM), Marginal Zone Lymphoma (MZL), Follicular Lymphoma (FL), or Primary Central Nervous System Lymphoma (PCNSL). Phase 1b will investigate the efficacy of NX-5948 at the dose(s) selected in Phase 1a in up to 7 expansion arms of patients with histologically confirmed R/R B-cell malignancy indications who have received the specified prior therapies based on indication:
