    Title:

    1635 Preliminary Results of a Phase Ⅱ Study of Zanubrutinib Combined with Immunochemotherapy in Patients with CD79A/CD79B-Mutant Diffuse Large B-Cell Lymphoma

    Published date:
    11/03/2022
    Excerpt:
    Zanubrutinib (160 mg po bid) combined with investigator-determined conventional salvage chemotherapy (CSC, including ICE, DHAP, GDP, or GemOx, +/- rituximab)...There were 10 CRs (83.3%) and 2 PRs (16.7%) in the TN cohort; 5 CRs (55.6%), 2 PRs (22.2%), and 2 PDs (22.2%) in the R/R cohort….CD79A/CD79B mutation was frequent in DLBCL patients, especially in R/R cases. Zanubrutinib combined with immunochemotherapy showed encouraging activity and acceptable tolerance in pts with CD79A/CD79B-mutant DLBCL.

    Zanubrutinib (160 mg po bid) combined with investigator-determined conventional salvage chemotherapy (CSC, including ICE, DHAP, GDP, or GemOx, +/- rituximab) was administered in R/R cohort...In the R/R cohort, the responses were CR in 4 (51.7%) pts, partial response (PR) in 2 (28.6%) pts, and progression disease (PD) in 1 (14.3%) patient….CD79A/CD79B mutation was frequent in DLBCL patients, especially in R/R cases. Zanubrutinib combined with immunochemotherapy showed encouraging activity and acceptable tolerance in pts with CD79A/CD79B-mutant DLBCL.
