Study Summary

Study CX-659-401 is a multicenter, open-label, phase 2 study of mivavotinib to evaluate the single-agent activity of mivavotinib in patients with relapsed/refractory non-GCB/ABC DLBCL, incorporating ctDNA-based next-generation sequencing (NGS) to identify DLBCL patients harboring MyD88 and/or CD79B mutations within the study. This goal of this strategy is to evaluate its activity both in the cell-of-origin subgroup of non-GCB/ABC DLBCL and in the genetically defined subgroups of MyD88/CD79B-mutated and wild type DLBCL.

Primary Outcome

Overall response is defined as a complete response (CR) or partial response (PR). ORR is the proportion of participants who have overall responses.
