Brief Title  ICMJE INCB18424 in Treating Young Patients With Relapsed or Refractory Solid Tumor, Leukemia, or Myeloproliferative Disease
Official Title  ICMJE A Phase I Study of JAK Inhibition (INCB018424) in Children With Relapsed or Refractory Solid Tumors, Leukemias, and Myeloproliferative Neoplasms
Brief Summary

RATIONALE: INCB18424 (Ruxolitinib) may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase 1 clinical trial is studying the side effects and best dose of INCB18424 in treating young patients with relapsed or refractory solid tumor, leukemia, or myeloproliferative disease.

Detailed Description

OBJECTIVES:

Primary

  • To estimate the maximum-tolerated dose and/or recommended phase II dose of oral JAK inhibitor INCB18424 administered continuously, twice daily to pediatric patients with relapsed or refractory solid tumors.
  • To define and describe the toxicities of this treatment administered on this schedule in pediatric patients with relapsed or refractory solid tumors, leukemias, or myeloproliferative neoplasms (MPNs).
  • To characterize the pharmacokinetics of this treatment in pediatric patients with relapsed or refractory solid tumors, leukemias, or MPNs.

Secondary

  • To preliminarily define the antitumor activity of this treatment within the confines of a phase I study.
  • To assess the biologic activity of oral JAK inhibitor INCB18424 upon JAK-STAT signaling in pediatric patients with relapsed or refractory solid tumors, leukemias, or MPNs.
  • To assess the cytotoxicity and biologic activity of oral JAK inhibitor INCB18424 upon phosphosignaling and mutation burden in pediatric patients whose leukemias or MPNs have known CRLF2 and/or JAK mutations.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive oral JAK inhibitor INCB18424 twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients with relapsed or refractory leukemia may receive intrathecal chemotherapy in course 2 and subsequent courses at the discretion of the treating physician.

Plasma, bone marrow, and blood samples may be collected at baseline, during course 1, and before subsequent courses for pharmacokinetic analysis and correlative biology studies.

After completion of study treatment, patients are followed up for 30 days.

Eligibility Criteria  ICMJE

DISEASE CHARACTERISTICS:

  • Histologically confirmed diagnosis of one of the following:

    • Relapsed or refractory extracranial solid tumor
    • Relapsed or refractory leukemia

      • At least 25% blasts in the bone marrow (M3) with the exception of patients with acute myeloid leukemia (AML), who must have > 20% blasts in the bone marrow
    • Relapsed or refractory myeloproliferative neoplasm (MPN)

      • At original diagnosis or relapse
      • Current diagnostic criteria for MPNs include polycythemia vera, essential thrombocythemia, juvenile myelomonocytic leukemia, myelofibrosis, and atypical chronic myeloid leukemia
    • Relapsed or refractory leukemia or MPN that have confirmed JAK mutations and/or positive TSLPR surface staining

      • Testing for JAK mutations and/or confirmed positive flow cytometry surface staining for the thymic stromal lymphopoietin receptor (TSLPR; encoded by CRLF2); eligibility for part C will be contingent upon patients demonstrating overexpression of CRLF2 by flow cytometric methods measured at either JHU or U. Washington flow laboratories (therefore, pre-enrollment samples need to be sent to one of these laboratories after discussion with Dr. Loh) or if the patient has a CLIA lab documented alteration in JAK1 or JAK2, SH2B3, IL7RA, or another gene that would predict sensitivity to JAK inhibition.
  • Measurable or evaluable disease (for patients with solid tumors)
  • Current disease state is one for which there is no known curative therapy or therapy proven to prolong survival with an acceptable quality of life
  • No known active CNS involvement (radiographic or cytologic)
