Abstract
This phase II study evaluated YM155, a novel small-molecule survivin suppressant, in combination with rituximab in patients with relapsed aggressive B-cell non-Hodgkin lymphoma (NHL) who failed or were not candidates for autologous stem cell transplant (ASCT). During 14-day cycles, 41 patients received YM155 (5mg/m(2)/d) by continuous intravenous (IV) infusion for 168 hours (day 1-7), and rituximab (375mg/m(2)) IV on days 1 and 8 during cycles 1-4 and repeated for 4 cycles every 10 cycles. Forty patients (97.6%) had prior rituximab and 15 patients (36.6%) prior ASCT. Most frequent grade 3-4 adverse events were neutropenia (19.5%) and thrombocytopenia (12.2%). In the per-protocol set (n = 34), objective response rate was 50% and median progression-free survival 17.9 months. Median overall survival was not reached at study termination (median follow-up, 23 months). YM155 in combination with rituximab was tolerable with encouraging antitumor activity and durable responses in relapsed aggressive B-cell NHL patients.
