Hyper-CVAD and Sequential Blinatumomab Without and With Inotuzumab in Young Adults With Newly Diagnosed Philadelphia Chromosome-Negative B-Cell Acute Lymphoblastic Leukemia.

ABSTRACT: Adding inotuzumab ozogamicin (InO) to hyper-CVAD and blinatumomab may improve outcomes in newly diagnosed Philadelphia chromosome (Ph)-negative B-cell acute lymphoblastic leukemia (B-ALL). Patients with newly diagnosed B-ALL received up to four cycles of hyper-CVAD followed by four cycles of blinatumomab. Beginning with patient #39, InO 0.3 mg/m² was added on Days 1 and 8 to two cycles of high-dose methotrexate and cytarabine, and two cycles of blinatumomab. The primary endpoint was the relapse-free survival (RFS) rate. Seventy-five patients were treated (median age of 33 years; range, 18-59), of whom 37 (49%) received hyper-CVAD with blinatumomab and InO (cohort 2). Measurable residual disease (MRD) negativity by next-generation sequencing (sensitivity: 1 × 10^-6) was
