Chinese Children's Cancer Group-2025 Protocol for Newly Diagnosed for Intermediate/High Risk Childhood B-cell ALL
In Brief
A Phase 3 clinical trial evaluating Blinatumomab (Group A), Venetoclax (nonRand Group), and 1 other intervention for Acute Lymphoblastic Leukemia ALL and 2 related conditions. Currently recruiting, targeting 1,800 participants across 26 sites in 2 countries.
Detailed Summary
Building upon the results from the CCCG-ALL-2015, CCCG-ALL-2020 multicenter study cohort, concurrent research findings, and the latest clinical trials, the CCCG-ALL-2025 I/HR-B-ALL is thus developed to further improve the event-free survival (EFS), and overall survival (OS), and quality of life (QoL) of children with intermediate- and high- risk B-cell childhood acute lymphoblastic leukaemia (I/HR-B-ALL), while decreasing adverse reactions and transplantation rates. This trial primarily aims to explore: 1. The efficacy of two randomized Blinatumomab application scheme on I/HR-ALL as determined by MRD negatvitiy rate. 2. The efficacy of modified mini-hyperCVD + Venetoclax in I/HR-ALL cannot afford blinatumomab, in contrast to historical control as determined by MRD negatvitiy rate.

Timeline
Interventions
For Group A I/HR-ALL patients after induction remission phase, continuous 28 days' blinatumomab followed by 3 cycles of high-dose methotrexate (HDMTX) will be applied, subsequently followed by interim continuation, late intensification, and maintenance therapy
For I/HR patients non eligible for blinatumomab randomization, venetoclax+ mini-hyperCVD will be applied after PVDL induction, subsequently followed by CAT as intensification, interim continuation, late intensification, and maintenance therapy
For Group B I/HR-ALL patients after induction remission phase: a two 14-day cycles of blinatumomab, alternating with three cycles of HDMTX will be applied, subsequently followed interim continuation, late intensification, and maintenance therapy
