Prexasertib in Treating Pediatric Patients With Recurrent or Refractory Solid Tumors

Status: Recruiting
Phase:
DFCI Protocol ID: 17-703

This phase I trial studies the side effects and best dose of prexasertib in treating pediatric patients with solid tumors that have come back after a period of time during which the tumor could not be detected or does not respond to treatment. Checkpoint kinase 1 inhibitor LY2606368 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Inclusion Criteria:

  -  Patients with recurrent or refractory solid tumors, including central nervous system
     (CNS) tumors, are eligible; patients must have had histologic verification of
     malignancy at original diagnosis or relapse except in patients with intrinsic brain
     stem tumors, optic pathway gliomas, or in patients with pineal tumors and elevations
     of cerebrospinal fluid (CSF) or serum tumor markers including alpha-fetoprotein or
     beta-human chorionic gonadotropin (HCG)

  walk because of paralysis, but who are up in a wheelchair, will be considered
  ambulatory for the purpose of assessing the performance score

  -  Patients must have fully recovered from the acute toxic effects of all prior
     anti-cancer therapy and must meet the following minimum duration from prior
     anti-cancer directed therapy prior to enrollment; if after the required timeframe,
     the defined eligibility criteria are met, e.g. blood count criteria, the patient is
     considered to have recovered adequately

  the duration of this interval must be discussed with the study chair and the
  study-assigned research coordinator prior to enrollment

    -  >= 21 days after the last dose of cytotoxic or myelosuppressive
       chemotherapy (42 days if prior nitrosourea)

       -  Anti-cancer agents not known to be myelosuppressive (e.g. not associated with
  reduced platelet or absolute neutrophil count [ANC] counts): >= 7 days must have
  elapsed from last dose of agent; the duration of this interval must be discussed
  with the study chair and the study-assigned research coordinator prior to
  enrollment

       -  Hematopoietic growth factors: >= 14 days must have elapsed since the last dose
  of a long-acting growth factor (e.g. pegfilgrastim) or 7 days for short-acting
  growth factor; for agents that have known adverse events occurring beyond 7 days
  after administration, this period must be extended beyond the time during which
  adverse events are known to occur; the duration of this interval must be
  discussed with the study chair and the study-assigned research coordinator

  factors): >= 21 days must have elapsed since the completion of interleukins,

       have elapsed after completion

       -  Cellular therapy: >= 42 days must have elapsed since the completion of any type
  of cellular therapy (e.g. modified T cells, natural killer [NK] cells, dendritic
  cells, etc.)

       -  X ray (XRT)/external beam irradiation including protons: >= 14 days must have
  elapsed after local XRT; >= 150 days after TBI, craniospinal XRT or if radiation
  to >= 50% of the pelvis; >= 42 days if other substantial bone marrow (BM)
  radiation

       -  Radiopharmaceutical therapy (e.g., radiolabeled antibody, 131 iodine
  metaiodobenzylguanidine [131I-MIBG]): >= 42 days must have elapsed since
  systemically administered radiopharmaceutical therapy

       -  Patients must not have received prior exposure to LY2606368

  -  For patients with solid tumors without known bone marrow involvement:

       -  Peripheral absolute neutrophil count (ANC) >= 1000/mm^3

       -  Platelet count >= 75,000/mm^3 (transfusion independent, defined as not receiving
  platelet transfusions for at least 7 days prior to enrollment)

       -  Hemoglobin >= 8.0 g/dl at baseline (may receive packed red blood cell [PRBC]
