INCB18424 in Treating Young Patients With Relapsed or Refractory Solid Tumor, Leukemia, or Myeloproliferative Disease
RATIONALE: INCB18424 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
PURPOSE: This phase I 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.

- 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.
- 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.
