Brief Summary

Compared with patients with philadelphia chromosome-negative Acute Lymphoblastic Leukemia (Ph- ALL), patients with Ph-positive (Ph+) ALL exhibit a comparatively poor prognosis. Fortunately, significant improvements have been found in response rates, disease-free survival (DFS), and overall survival (OS) for patients with Ph+ ALL with the introduction of tyrosine kinase inhibitor (TKI) therapy to treatment regimens. Based on improvements in efficacy and tolerability, next-generation TKIs have been widely used in first-line treatment for chronic myeloid leukemia (CML). Flumatinib, a TKI with more potent binding affinity for BCR-ABL1 tyrosine kinase than imatinib, demonstrated higher rates of responses, faster and deeper responses in FESTnd trial, which suggested that flumatinib might show improved clinical efficacy for treating Ph+ ALL compared with imatinib. The investigators therefore hypothesized that the addition of flumatinib to combinatorial chemotherapy regimen would demonstrate greater efficacy compared with the prior use of imatinib in treating Ph+ ALL. This study explored the safety and efficacy of flumatinib versus imatinib when combined with multi-agent chemotherapy in patients with newly diagnosed Ph+ ALL.

Conditions

Acute Leukemia

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

flumatinib arm

600 mg QD oral administration, fasting (2 hours before administration and 1 hour after administration).

Group Type: EXPERIMENTAL

Flumatinib

Intervention Type: DRUG

Flumatinib 600 mg qd will be given orally along with combination chemotherapy starting day 8 of induction chemotherapy. Flumatinib will be given continuously (if it's tolerable) for 2 years since achievement of complete remission (CR) as part of consolidation chemotherapy and maintenance therapy. Patients can receive allogeneic hematopoietic stem cell transplantation (HSCT),or patients in whom MCR was achieved within 3 months after treatment and continued until transplantation can receive autologous HSCT whenever possible during their first CR. Otherwise, they will finish the consolidation and maintenance chemotherapy.

imatinib arm

600 mg QD oral administration, with a meal

Group Type: ACTIVE_COMPARATOR

Imatinib

Intervention Type: DRUG

Imatinib 600 mg qd will be given orally along with combination chemotherapy starting day 8 of induction chemotherapy. Imatinib will be given continuously (if it's tolerable) for 2 years since achievement of complete remission (CR) as part of consolidation chemotherapy and maintenance therapy. Patients can receive allogeneic hematopoietic stem cell transplantation (HSCT),or patients in whom MCR was achieved within 3 months after treatment and continued until transplantation can receive autologous HSCT whenever possible during their first CR. Otherwise, they will finish the consolidation and maintenance chemotherapy.
