Summary

ABC study is a phase 2, single-arm, open-label study of Olverembatinib, CD3/CD19 Bispecific T-cell Engager, and Chidamide in patients with newly diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia (Ph+ALL). This study combined third generation TKI (Olverembatinib), histone deacetylase inhibitors (Chidamide) and CD3/CD19 bispecific T-cell engager (Blinatumomab) as first line regimen (ABC regimen) for Ph+ ALL. Investigatorsaim to explore the efficacy and safety of ABC regimen. The primary endpoint is the complete molecular remission （CMR） at 3 months, secondary endpoints are overall survival (OS), event-free survival (EFS), adverse event (AE), IKZF1del, IKZF1plus, IKZF1lpus/CD20 subgroup EFS/OS.
