What was measured

ORR was calculated as follows: number of participants in the primary analysis set achieving a best overall response of complete remission without platelet recovery (CRp) or complete remission (CR), divided by the number of participants in the primary analysis set. The most positive response for each patient during the study was counted. The 95% CI was calculated using binomial parameter exact method. Response was determined by the investigator, and evaluated per Jeha et al, 2006: A CR required no evidence of circulating blasts or extramedullary disease, an M1 marrow (≤ 5% bone marrow blasts), and recovery of peripheral counts (platelets ≥ 100 × 10\^9/L and absolute neutrophil count ≥ 1.0 × 10\^9/L). A CR without platelet recovery (CRp) required all of the criteria for a CR with the exception of platelet recovery.

Analysis population: The primary analysis set for efficacy included all participants treated at the RP2D in Phase 2.

Groups in this outcome

Phase 2: Bendamustine 120 mg/m^2

Bendamustine 120 mg/m\^2 administered as an IV infusion over 60 minutes on Days 1 and 2 of each 21-day cycle (Cycles 2 through 12), with delays up to 2 weeks for neutrophil and platelet count recovery, for up to a 35-day cycle.
