Efficacy and Safety of Glofitamab Plus Polatuzumab Vedotin in Relapsed/Refractory Large B-Cell Lymphoma Including High-Grade B-Cell Lymphoma: Results From a Phase Ib/II Trial.

ABSTRACT:

Purpose

An unmet need remains for more effective therapies for relapsed/refractory (R/R) large B-cell lymphoma (LBCL), especially high-grade B-cell lymphoma (HGBCL). We present the primary analysis of a phase Ib/II study (ClinicalTrials.gov identifier: NCT03533283) investigating efficacy and safety of glofitamab plus polatuzumab vedotin (Glofit-Pola) in patients with R/R LBCL, including HGBCL and those who received previous chimeric antigen receptor (CAR) T-cell therapy.

Methods

Patients received 1,000 mg obinutuzumab on Cycle (C)1 Day (D)1 (once daily). Polatuzumab vedotin (1.8 mg/kg) was given on C1D2 and D1 of C2-6 (21-day cycles; once daily). Glofitamab was given as step-up doses in C1 (D8, 2.5 mg; D15, 10 mg) followed by 30 mg on D1 of C2-12 (21-day cycles; once daily).
