Key clinical point: Fixed-duration ibrutinib-venetoclax vs chlorambucil-obinutuzumab continues to extend progression-free survival and leads to overall survival advantage at a 4-year follow-up in patients with previously untreated chronic lymphocytic leukemia (CLL).
Major finding: At a median follow-up of 46 months, the ibrutinib-venetoclax vs chlorambucil-obinutuzumab group continued to show better progression-free survival (hazard ratio [HR] 0.214; P < .0001) while also demonstrating overall survival benefit (HR 0.487; P = .021). One treatment-related death was reported in each group.
Study details: Findings are from a 4-year follow-up of the phase 3 GLOW trial including 211 patients with previously untreated CLL who were randomly assigned to receive ibrutinib-venetoclax or chlorambucil-obinutuzumab.
Disclosures: This study was funded by Janssen Research & Development and Pharmacyclics. Several authors declared serving on the boards of directors or advisory committees of or receiving consultancy fees, research funding, or honoraria from various sources, including Janssen. Nine authors declared being employees or equity holders of Janssen.
