A Study of NX-2127 in Adults With Relapsed/Refractory B-cell Malignancies
brief summary
This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-2127 in patients with advanced B-cell malignancies.
detailed description
Phase 1a (Dose Escalation) will evaluate the safety and tolerability of NX-2127 in adult patients with relapsed/refractory (R/R) B-cell malignancies, who have required and received at least 2 prior systemic therapies (or at least 1 prior therapy for patients with WM or PCNSL) and for which no other therapies are known to provide clinical benefit.
Phase 1b (Dose Optimization) will use a 2-stage design to further investigate the safety, tolerability, and preliminary efficacy of NX-2127 in R/R B-cell malignancies based on the dosage(s) selected in Phase 1a.
Stage 1 will enroll approximately 10 participants per group based on B-cell lymphoma/leukemia indication at a specific dose selected from the first part of the study. The Sponsor may decide to open Stage 2 for any given group after review of safety and anti-tumor activity data from Stage 1.
In Stage 2, an additional 10 participants will be enrolled at the dose from Stage 1 as well as 20 additional participants at a second alternative dose. Participants will be randomly assigned to one of the 2 dose levels in Stage 2.
