A Phase 1 Study of LY2606368 (Prexasertib Mesylate Monohydrate) a CHK1/2 Inhibitor, in Pediatric Patients With Recurrent or Refractory Solid Tumors, Including CNS Tumors

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.

PRIMARY OBJECTIVES:

I. To estimate the maximum tolerated dose (MTD) and/or recommended phase 2 dose of
prexasertib (LY2606368) administered as an intravenous (IV) infusion over 60 minutes, every
14 days of a 28-day cycle to children with recurrent or refractory solid tumors.

II. To define and describe the toxicities of LY2606368 administered on this schedule.

III. To characterize the pharmacokinetics of LY2606368 in children with recurrent or
refractory cancer.

SECONDARY OBJECTIVES:

I. To preliminarily define the antitumor activity of LY2606368 within the confines of a phase
1 study.

II. To examine checkpoint kinase (CHK)1/2 expression status in archival tumor tissue from
solid tumor pediatric patients using immunohistochemistry.

III. To evaluate tumor tissue for deletion and/or mutation of tumor protein 53 (Trp53) as a
potential biomarker of Chk1 inhibition.

IV. To evaluate autophosphorylation of Chk1 and H2A histone family, member x (H2AX) in
peripheral blood mononuclear cells as a potential pharmacodynamic marker of LY2606368
activity.

OUTLINE: This is a dose-escalation study.

Patients receive prexasertib IV over 60 minutes on days 1 and 15. Treatment repeats every 28
days for up to 13 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

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

adverse events are known to occur; the duration of this interval must be
discussed with the study chair and the study-assigned research coordinator

graft-versus-host disease (GVHD)

- Autologous stem cell infusion including boost infusion: >= 42 days must 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

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