Final overall survival results of a randomized trial comparing bortezomib plus pegylated liposomal doxorubicin with bortezomib alone in patients with relapsed or refractory multiple myeloma
Abstrakt
BACKGROUND: Previous results from an interim analysis of an open-label, randomized, phase 3 study demonstrated that bortezomib combined with pegylated liposomal doxorubicin (PLD) was superior to bortezomib monotherapy in patients with relapsed/refractory multiple myeloma who had previously received one or more lines of therapy. Protocol-defined final survival data from that study are provided here.
METHODS: Patients were randomized (1:1) to receive either bortezomib alone (1.3 mg/m2 intravenously on days 1, 4, 8, and 11 of every 21-day cycle) or bortezomib-PLD (bortezomib plus PLD 30 mg/m2 intravenously on day 4). The primary endpoint was the time to progression.
Secondary efficacy endpoints included overall survival (OS), progression-free survival, and the overall response rate.
