Philadelphia-Positive ALL

Participants will have a sample of their white blood cells, called T cells, collected using a procedure called leukapheresis. The collected T cells will be sent to a laboratory to be changed (modified) to become 19-28z/IL-18, the CAR T-cell therapy that participants will receive during the study. Making the participants' study therapy will take about 2-4 weeks.

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.

The goal of this prospective, multicenter, open observational study is to assess the efficacy and safety of the treatment for acute lymphoblastic leukemia Ph' positive adult patients with approved combinations of chemotherapy and tyrosine kinase inhibitor (TKI). Efficay refers to the rate of Complete Molecular Response (BCR::ABL1/ABL1 ratio 0.01%) in eah treatment arm. Safety refers to measurement of i) Adverse events (AEs) and serious adverse events (SAEs) according to standard clinical and laboratory tests (hematology and chemistry, physical examination, vital sign measurements, and diagnostic tests), ii) incidence and degree of cytopenias and iii) incidence and degree of infections. Low-dose chemotherapy will be given together with the TKI imatinib to patients of all ages as induction to remission phase. Consolidation treatment will continue with low-dose chemotherapy with imatinib if the patient fullfills both criteria: to show a measurable residual disease (MRD) value lower than 0,01% at 3 month of therapy, and not showing IKZF1plus genetics Those patients have any of these 2 conditions will be considered high-risk patients and will recieve consolidation treatment intensification with low-dose chemotherapy plus ponatinib as TKI and allogeneic stem cell transplantation (allo SCT). The remaining patients (standard-risk) will receive maintenance chemotherapy together with imatinib or ponatinib and will not be submitted to alloSCT.

This is a multicenter, prospective, phase II study for adult de novo Philadelphia chromosome-positive acute lymphoid leukemia (Ph+ ALL) based on the combination of Olverembatinib and Blinatumomab. Olverembatinib will be taken 40mg qod from the time of diagnosis, and Blinatumomab will be given intravenously up to five cycles.
