Effectiveness and Safety of Polatuzumab Vedotin Plus an Anti-CD20 Monoclonal Antibody (Rituximab or Obinutuzumab) and Zanubrutinib in Relapsed/Refractory Diffuse Large B-Cell Lymphoma.

ABSTRACT:

Background

Approximately 30% of patients with diffuse large B-cell lymphoma (DLBCL) relapse or are refractory to first-line treatment. This study aimed to determine the effectiveness and tolerability of the combination of Polatuzumab vedotin and Zanubrutinib plus Rituximab (Pola-ZR) or Obinutuzumab (Pola-ZG) in patients with relapsed/refractory (R/R) DLBCL.

Methods

We conducted a prospective observational study as part of our registered cohort study (NCT06203652). Patients were planned to receive six 21-day cycles of Pola-ZR/G, followed by Zanubrutinib monotherapy. The primary endpoint was to evaluate the best overall response rate (BOR), while secondary endpoints included the median progression-free survival (mPFS), safety, and complete response rate (CRR). We collected dat
