  Purpose

RATIONALE: AT9283 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase I/IIa clinical trial is studying the side effects and best dose of AT9283 in treating young patients with relapsed or refractory acute leukemia.

Detailed Description:

OBJECTIVES:

Primary

  • To identify the maximum-tolerated dose and recommended phase IIb dose of multikinase inhibitor AT9283 in pediatric patients with relapsed or refractory acute leukemia.

Secondary

  • To evaluate the safety and tolerability of this drug in these patients.
  • To document evidence of efficacy of this drug in these patients.
  • To investigate the pharmacokinetic profile of this drug in plasma in these patients.

Tertiary

  • To assess target kinase inhibition by multikinase inhibitor AT9283 in these patients.
  • To identify potential predictive molecular biomarkers in these patients.

OUTLINE: This is a multicenter study.

Patients receive multikinase inhibitor AT9283 IV continuously over 72 hours. Treatment repeats every 21 days* for 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving benefit of treatment may continue for up to 6 more courses at the discretion of the chief/principal investigator.

NOTE: *Course length may be extended to a maximum 42 days to allow for recovery of blood counts. Intrathecal therapy is permitted from course 2 onwards in patients with ALL.

Blood specimens are collected for pharmacokinetic and pharmacodynamic studies including molecular predictive biomarkers and ex vivo and in vivo measurement of kinase inhibition assessments.

After completion of study treatment, patients are followed up for 42 days or until recovery of blood counts (whichever is the sooner).

      • Not eligible for any therapy of higher curative potential
  • No chronic myeloid leukemia (CML)
  • Patients in relapse must have ≥ 5% blasts in the bone marrow
  • Patients with refractory disease following induction must have ≥ 20% blasts in the bone marrow
  • No evidence of CNS disease

PATIENT CHARACTERISTICS:

  • Serum bilirubin < 1.5 times upper limit of normal (ULN)
  • ALT or AST < 2.5 times ULN (5 times ULN if due to leukemic infiltration of the liver)
  • Creatinine clearance ≥ 60 mL/min
  • Not pregnant or nursing
  • Negative pregnancy test
  • Fertile female patients must use 2 of the following combined forms of contraception (oral, injected, or implanted hormonal contraception and condom OR intra-uterine device and condom OR diaphragm with spermicidal gel and condom) before, during, and for 6 months after completion of study therapy
  • Male patients must use 1 form of highly effective contraception (condom plus spermicidal gel) during and for 6 months after completion of study therapy

    • Men with pregnant or lactating partners should be advised to use barrier-method contraception (condom plus spermicidal gel)

  • No active graft-vs-host disease
  • No current non-malignant systemic disease considered high medical risk, including any of the following:

    • Active uncontrolled infection

  • No other condition that, in the Investigator's opinion, would not make the patient a good candidate for the clinical trial

PRIOR CONCURRENT THERAPY:

  • Recovered from toxicity of prior therapy, including toxicity following hematopoietic stem cell transplantation

    • Alopecia or certain grade 1 toxicities allowed at the discretion of the Investigator
