Updated Results from a Phase II Study of Hyper-CVAD, with or without Inotuzumab Ozogamicin, and Sequential Blinatumomab in Patients with Newly Diagnosed B-Cell Acute Lymphoblastic Leukemia (ASH 2023)

Pts received hyper-CVAD alternating with high-dose methotrexate (MTX) and cytarabine (Ara-C) for up to 4 cycles, followed by 4 cycles of blinatumomab at standard doses. Pts with CD20+ disease (≥1% cells) received 8 doses of ofatumumab (2000 mg) or rituximab (375 mg/m2)...One pt discontinued blinatumomab due to a related adverse event (grade 2 encephalopathy and dysphasia). No pts discontinued INO due to toxicity, and no cases of veno-occlusive disease have been observed.

HYPER-CVAD WITH BLINATUMOMAB AND INOTUZUMAB OZOGAMICIN FOR PATIENTS WITH NEWLY DIAGNOSED PHILADELPHIA CHROMOSOME-NEGATIVE B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA: A PHASE II STUDY (EHA 2023)

Pts received hyper-CVAD alternating with high-dose methotrexate and cytarabine for up to 4 cycles, followed by 4 cycles of blinatumomab at standard doses. Pts with CD20+ disease (≥1% cells) received 8 doses of ofatumumab (2000 mg) or rituximab (375 mg/m2)...In pts with newly diagnosed Ph-negative B-cell ALL receiving hyper-CVAD with sequential blinatumomab, the addition of INO is safe and may improve survival.

The Addition of Inotuzumab Ozogamicin to Hyper-CVAD Plus Blinatumomab Further Improves Outcomes in Patients with Newly Diagnosed B-Cell Acute Lymphoblastic Leukemia: Updated Results from a Phase II Study (ASH 2022)

Pts with CD20+ disease (≥1% cells) received 8 doses of ofatumumab (2000 mg) or rituximab (375 mg/m2)...Beginning with pt #39, INO at a dose of 0.3 mg/m2 on day 1 and 8 was added to the 2 cycles of MTX/Ara-C and to 2 cycles of blinatumomab consolidation (4 total cycles with INO)... The addition of INO to hyper-CVAD with sequential blinatumomab is safe and highly effective as frontline treatment of Ph-negative B-cell ALL. This study shows the feasibility of incorporating both INO and blinatumomab into the frontline treatment of pts with B-cell ALL. Outcomes of the pts treated in the INO cohort are particularly promising.

Chemotherapy Resistance in B-ALL with Cryptic NUP214-ABL1 Is Amenable to Kinase Inhibition and Immunotherapy. (PubMed, Oncologist)

The addition of dasatinib targeting NUP214-ABL1 to inotuzumab resulted in complete molecular remission, but recurrence occurred rapidly with dasatinib alone. However, deep molecular remission was recaptured with a combination of blinatumomab and ponatinib, so he could proceed to allotransplantation. This case illustrates that next-generation sequencing approaches designed to discover cryptic gene fusions can benefit patients with Ph-like ALL.

HYPER-CVAD WITH SEQUENTIAL BLINATUMOMAB, WITH OR WITHOUT INOTUZUMAB OZOGAMICIN, IN ADULTS WITH NEWLY DIAGNOSED PHILADELPHIA CHROMOSOME-NEGATIVE B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA (EHA 2022)

Pts received hyper-CVAD alternating with high-dose methotrexate and cytarabine for up to 4 cycles, followed by 4 cycles of blinatumomab at standard doses. Pts with CD20+ disease (≥1% cells) received 8 doses of ofatumumab (2000 mg) or rituximab (375 mg/m 2 )...Conclusion Hyper-CVAD with sequential blinatumomab, with or without INO, is highly effective as frontline treatment of Ph-negative B-cell ALL, with an overall MRD negativity rate of 95% and a 3-year OS rate of 85%. Early outcomes with the addition of INO to this regimen are encouraging, with no relapses or deaths observed to date.

Clinico-Hematological Profile and Copy Number Abnormalities in a Cohort of STIL-TAL1 and NUP214-ABL1 Positive Pediatric T-Cell Acute Lymphoblastic Leukemia. (PubMed, Indian J Hematol Blood Transfus)

NUP214-ABL1 fusion gene did not reveal any association with either CNVs or with survival. Although limited with the small cohort size and follow up, our study supports the similar frequency of these fusions as compared to other Asian and Western studies and also highlights utility of MLPA technique as a good diagnostic modality to screen for both STIL-TAL1 and NUP214-ABL1 fusions in a single assay with additional data on secondary copy number changes.

[VIRTUAL] Next Generation Genomic Analyses in T-ALL Patients Identify Recurrent and Novel Genomic Abnormalities (ASH 2020)

The top 20 mutated genes in our patient cohort differ to those reported for a pediatric cohort (Roberts et al 2019 Blood 134:649), indicating an association between patient age and genomic alteration. Secondary PDX models investigating novel targeted treatment strategies are ongoing.
