Clinical Trial Summary

This pilot phase II trial studies the side effects of azacitidine and combination chemotherapy in infants with acute lymphoblastic leukemia and KMT2A gene rearrangement. Drugs used in chemotherapy, such as methotrexate, prednisolone, daunorubicin hydrochloride, cytarabine, dexamethasone, vincristine sulfate, pegaspargase, hydrocortisone sodium succinate, azacitidine, cyclophosphamide, mercaptopurine, leucovorin calcium, and thioguanine work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug may kill more cancer cells.

Description:

PRIMARY OBJECTIVE:

I. To evaluate the tolerability of azacitidine in addition to Interfant-06 standard chemotherapy in infants with newly diagnosed acute lymphoblastic leukemia (ALL) with KMT2A gene rearrangement (KMT2A-R).

SECONDARY OBJECTIVE:

I. To evaluate the biologic activity of azacitidine by pharmacodynamic assessment of global deoxyribonucleic acid (DNA) methylation in peripheral blood mononuclear cells (PBMCs) of infants treated with azacitidine.

EXPLORATORY OBJECTIVES:

I. To determine the 5 year event-free survival (EFS) of infants with KMT2A-R treated with azacitidine in addition to Interfant-06 standard chemotherapy.

II. To correlate minimal residual disease (MRD) with outcome in the context of the protocol therapy.

III. To perform pharmacokinetic (PK) testing of azacitidine in infants. IV. To test the expansion of infant T lymphocytes by stimulation with artificial antigen presenting cells identical to those used in chimeric antigen receptor T-cell (CART)-19 production.

V. To collect pharmacodynamic (PD) data for asparaginase activity following pegaspargase administration in infants.

OUTLINE:

INDUCTION CHEMOTHERAPY: Patients receive methotrexate intrathecally (IT) on days 1 and 29, prednisolone orally (PO) or nasogastrically (NG) three times daily (TID) on days 1-7, daunorubicin hydrochloride intravenously (IV) over 1-15 minutes on days 8-9, cytarabine IV over 30 minutes on days 8-21 and IT on day 15, dexamethasone PO, NG, or IV TID on days 8-28, vincristine sulfate IV over 1 minute on days 8, 15, 22, and 29, pegaspargase IV over 1-2 hours or intramuscularly (IM) on day 12, and hydrocortisone sodium succinate IT on days 15 and 29 in the absence of disease progression or unacceptable toxicity. Only patients with KMT2A-R continue to post-induction chemotherapy.

POST-INDUCTION CHEMOTHERAPY:

AZACITIDINE BLOCK I: Prior to CONSOLIDATION, patients receive azacitidine IV over 10-40 minutes daily for 5 days in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Following completion of AZACITIDINE BLOCK I, patients receive cyclophosphamide IV over 30-60 minutes on days 1 and 29, mercaptopurine PO or NG daily on days 1-28, cytarabine IV or subcutaneously (SC) daily on days 3-6, 10-13, 17-20, and 24-27 and IT on day 10, methotrexate IT on day 24, and hydrocortisone sodium succinate IT on days 10 and 24 in the absence of disease progression or unacceptable toxicity.

AZACITIDINE BLOCK II: Prior to INTERIM MAINTENANCE, patients receive azacitidine as in AZACITIDINE BLOCK I

INTERIM MAINTENANCE: Following completion of AZACITIDINE BLOCK II, patients receive mercaptopurine PO or NG daily on days 1-14, methotrexate IV over 24 hours on days 1 and 8 and IT on days 2 and 9, leucovorin calcium PO or IV on days 3-4 and 10-11, hydrocortisone sodium succinate IT on days 2 and 9, cytarabine IV over 3 hours every 12 hours on days 15-16 and 22-23 for a total of 8 doses, and pegaspargase IV over 1-2 hours or IM on day 23 in the absence of disease progression or unacceptable toxicity.

AZACITIDINE BLOCK III: Prior to DELAYED INTENSIFICATION PART I, patients receive azacitidine as in AZACITIDINE BLOCK I.

DELAYED INTENSIFICATION PART I: Following completion of AZACITIDINE BLOCK III, patients receive pegaspargase IV over 1-2 hours or IM on day 1, dexamethasone PO, NG, or IV TID on days 1-14 and 15-21 with a taper on days 15-21, thioguanine PO or NG daily on days 1-28, vincristine sulfate IV over 1 minute on days 1, 8, 15, and 22, daunorubicin hydrochloride IV over 1-15 minutes on days 1, 8, 15, and 22, cytarabine IV or SC on days 2-5, 9-12, 16-19, and 23-26 and IT on days 1 and 15, and hydrocortisone sodium succinate IT on days 1 and 15 in the absence of disease progression or unacceptable toxicity.

AZACITIDINE BLOCK IV: Prior to DELAYED INTENSIFICATION PART II, patients receive azacitidine as in AZACITIDINE BLOCK I.

Starting on day 169, patients receive mercaptopurine PO or NG on days 1-84 and methotrexate PO once weekly. Cycles repeat every 84 days for 2 years from the start of INDUCTION CHEMOTHERAPY in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.
