A Phase 1/2 Study of AZD1775 (MK-1775) in Combination With Oral Irinotecan in Children, Adolescents, and Young Adults With Relapsed or Refractory Solid Tumors

This phase I/II trial studies the side effects and best dose of adavosertib and irinotecan
hydrochloride in treating younger patients with solid tumors that have come back or that have
not responded to standard therapy. Adavosertib and irinotecan hydrochloride 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
adavosertib (AZD1755 [MK-1775]) administered on days 1 through 5 every 21 days, in
combination with oral irinotecan (irinotecan hydrochloride), to children with recurrent or
refractory solid tumors.

II. To define and describe the toxicities of AZD1755 (MK-1775) in combination with oral
irinotecan administered on this schedule.

III. To characterize the pharmacokinetics of AZD1755 (MK-1775) in children with refractory
cancer.

SECONDARY OBJECTIVES:

I. To preliminarily define the antitumor activity of AZD1755 (MK-1775) and irinotecan within
the confines of a Phase 1 study.

II. To obtain initial Phase 2 efficacy data on the anti-tumor activity of AZD1755 (MK-1775)
in combination with irinotecan administered to children with relapsed or refractory
neuroblastoma, in children with relapsed or refractory medulloblastoma/CNS PNET (central
nervous system primitive neuroectodermal tumor) and in children with relapsed or refractory
rhabdomyosarcoma.

III. To investigate checkpoint over-ride by AZD1755 (MK-1775) via the mechanism-based
pharmacodynamic (PD) biomarker of decreased cyclin-dependent kinase 1 (CDK1) phosphorylation
in correlative and exploratory studies.

IV. To evaluate potential predictive biomarkers of AZD1755 (MK-1775) sensitivity, including
v-myc avian myelocytomatosis viral oncogene homolog (MYC), v-myc avian myelocytomatosis viral
oncogene neuroblastoma derived homolog (MYCN), phosphorylated-WEE1 G2 checkpoint kinase
(p-Wee1), enhancer of zeste homolog 2 (Drosophila) (EZH2) and gamma-H2A histone family,
member gamma-H2AX in tumor tissues in correlative and exploratory studies.

unacceptable toxicity.

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