Fludarabine, Cytarabine, and Pegcrisantaspase for the Treament of Relapsed or Refractory Leukemia

February 29, 2024 updated by: M.D. Anderson Cancer Center

Phase Ib Study of Fludarabine, Cytarabine (Ara-C) and Pegylated Erwinase (Pegcrisantaspase) in Patients With Relapsed or Refractory Leukemia

This phase Ib trial investigates the side effects and best dose of pegcrisantaspase when given together with fludarabine and cytarabine for the treatment of patients with leukemia that has come back (relapsed) or has not responded to treatment (refractory). Pegcrisantaspase may block the growth of cancer cells. Chemotherapy drugs, such as fludarabine and cytarabine, 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 pegcrisantaspase in combination with fludarabine and cytarabine may work better in treating patients with leukemia compared to the combination of fludarabine and cytarabine.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability of fludarabine, cytarabine (araC), and pegcrisantaspase in patients with relapsed and refractory leukemias.

SECONDARY OBJECTIVES:

I. To determine the overall response rate (complete remission [CR], CR with incomplete count recovery [CRi], partial remission [PR], or morphologic leukemia free state [MLFS]) of a lead-in dose of single-agent pegcrisantaspase in patients with relapsed and refractory leukemias.

II. To determine the overall response rate (complete remission [CR], CR with incomplete count recovery [CRi], partial remission [PR], or morphologic leukemia free state [MLFS]) of fludarabine, araC, and pegcrisantaspase in patients with relapsed and refractory leukemias.

III. To assess overall survival (OS) and disease-free survival (DFS) of patients treated with fludarabine, araC, and pegcrisantaspase.

IV. To assess the duration of response to the combination in patients with advanced leukemias.

V. To characterize the pharmacokinetics (PK) pharmacodynamics (PD) anti-drug antibodies (ADA) of pegcrisantaspase in patients with relapsed and refractory leukemias.

EXPLORATORY OBJECTIVE:

I. Explore pretreatment and on-treatment biological correlates to predict sensitivity/resistance of pegcrisantaspase-based therapy.

OUTLINE: This is a dose-escalation study of pegcrisantaspase.

INDUCTION: Patients receive pegcrisantaspase intravenously (IV) over 60 minutes on days 1 and 15, and fludarabine IV over 15-30 minutes and cytarabine IV over 2 hours on days 8-11 in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Patients receive pegcrisantaspase IV over 60 minutes on days 1 and 15, and fludarabine IV over 15-30 minutes and cytarabine IV over 2 hours on days 8-10. Treatment repeats every 5 weeks for up 3 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6-12 months.

  • For cohort A of the expansion phase: Patients with a diagnosis untreated adverse-risk AML (as defined by ELN [European Leukemia Net Classification] 2017) will be enrolled
  • For cohort B of the expansion phase: Patients with a diagnosis of relapsed or refractory AML will be enrolled
  • Bilirubin =< 2 mg/dL
  • Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) =< 2.5 x upper limit of normal (ULN)
  • Creatinine =< 1.5 x ULN

  • Amylase and lipase =< 1.5 x ULN
  • Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
  • A negative urine pregnancy test is required within one week (7 days) for all women of childbearing potential prior to being registered on this trial
  • Patient must have the ability to understand the requirements of the study and signed informed consent. A signed informed consent by the patient or his legally authorized representative is required prior to their enrollment on the protocol

Exclusion Criteria:

  • Pregnant women are excluded from this study because the agents used in this study have the potential for teratogenic or abortifacient effects. Because there is a potential risk for adverse events in nursing infants secondary to treatment of the mother with the chemotherapy agents, breastfeeding should also be avoided
  • Uncontrolled intercurrent illness including, but not limited to active uncontrolled infection, symptomatic congestive heart failure (New York Heart Association [NYHA] class III or IV), unstable angina pectoris, clinically significant cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Patient with documented hypersensitivity to any of the components of the chemotherapy program
  • Prior treatment with pegylated asparaginase
  • Patients with a diagnoses of acute promyelocytic leukemia (AML-M3) will be excluded from this trial

  • Men and women of childbearing potential who do not practice contraception. Women of childbearing potential and men must agree to use contraception prior to study entry and for the duration of study participation. Effective methods of birth control include:

    • Birth control pills, shots, implants or patches
    • Intrauterine devices (IUDs)
    • Condom or occlusive cap (diaphragm or cervical/vault caps) used with spermicide
    • Abstinence
    • Females of non-childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation, oophorectomy, and/or hysterectomy
  • Patients with history of clinically significant venous thromboembolism
