Full-course Immunotherapy Combined With Chemotherapy in Newly Diagnosed B-cell Acute Lymphoblastic Leukemia (FLOW)
This is a single-arm, prospective, phase 2 clinical trial evaluating the improvement of survival outcomes of blinatumomab combined with chemotherapy as a full-course treatment regimen in patients with newly diagnosed Philadelphia chromosome-negative (Ph-negative) B-cell precursor acute lymphoblastic leukemia (B-ALL). The study adopts a "reduced-dose chemotherapy + full-course immunotherapy" strategy: induction therapy with reduced-dose chemotherapy combined with blinatumomab to improve remission rate and tolerability; consolidation therapy with alternating Hyper-CVAD (A/B) regimen,blinatumomab and sequential CD19-directed CAR-T therapy to deepen minimal residual disease (MRD) clearance; allogeneic hematopoietic stem cell transplantation (allo-HSCT) for some patients (e.g., KMT2A rearrangement, TP53 mutation, persistent MRD positivity, MRD recurrence); and no maintenance therapy.
The primary endpoint is 2-year relapse-free survival (RFS). Secondary endpoints include 2-year overall survival (OS), the proportion and time to achieve complete response (CRc), and the proportion and time to achieve minimal residual disease (MRD) negativity.
The trial plans to enroll 101 patients aged 15-65 years to demonstrate improved survival outcomes compared with historical controls .

Experimenteel: Experimental Arm:Blinatumomab + Chemotherapy
Patients receive reduced-dose chemotherapy combined with blinatumomab for induction, followed by alternating Hyper-CVAD(A/B) chemotherapy, blinatumomab and sequential CD19-directed CAR-T therapy for consolidation.
Patients (e.g., KMT2A rearrangement, TP53 mutation, persistent MRD positivity, MRD recurrence)receive allogeneic hematopoietic stem cell transplantation.
|
Induction phase: 9 µg/day on days 8-14, 28 µg/day on days 15-21; If D22 BM not CR/CRi, continue Blinatumomab for next 2 weeks of 28 µg/day; Consolidation phase: 28 µg/day for 28 days.
Reduced-dose induction regimen: Idarubicin 8 mg/m², intravenous, day 1; Vindesine 3 mg/m² (max 4 mg), intravenous, day 1; Dexamethasone 9 mg/m²/day, intravenous, days 1-7. Combined with blinatumomab Alternating intensive consolidation chemotherapy: Hyper-CVAD-A: Cyclophosphamide ,Vincristine , Doxorubicin , Dexamethasone ; Hyper-CVAD-B: Methotrexate , Cytarabine . Alternated with CD19-CART and blinatumomab
Allogeneic hematopoietic stem cell transplantation, performed after consolidation therapy in patients with KMT2A rearrangement, TP53 mutation, persistent MRD positivity or MRD recurrence
CD19-CART is administered sequentially in the consolidation phase: First infusion : Following the first course of blinatumomab (28 µg/day, IV, days 1-28) before subsequent Hyper-CVAD chemotherapy. Second infusion : After completion of alternating Hyper-CVAD and blinatumomab consolidation cycles. |

Tijdsspanne: From randomization to 2 cycles of induction before consolidation therapy(100 days)
|
Proportion of patients achieving complete remission (CR) or complete remission with incomplete hematologic recovery (CRi) after induction phase.CRc is evaluated at: 1) Day 22 after initial induction therapy; 2) After re-induction with blinatumomab for 2 weeks (for patients not achieving CRc at Day 22)
