I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose of 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.
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.
OUTLINE: This is a phase I, dose-escalation followed by a phase II study.
Patients receive irinotecan hydrochloride orally (PO) and WEE1 inhibitor MK-1775 PO on days 1-5. Treatment repeats every 21 days for 18 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up periodically.

Experimental: Treatment (irinotecan hydrochloride, WEE1 inhibitor MK-1775)

Drug: Irinotecan Hydrochloride
Other: Laboratory Biomarker Analysis

- Maximum tolerated dose (MTD) defined as the maximum doses of WEE1 inhibitor MK-1775 and irinotecan hydrochloride at which fewer than one-third of patients experience dose limiting toxicities when receiving this combination [ Time Frame: 21 days ]
- Pharmacokinetic (PK) parameters of WEE1 inhibitor MK-1775 in terms of systemic exposure [ Time Frame: Course 1 day 1 prior to the irinotecan infusion, prior to the MK-1775 dose, 4 hours after the dose of MK-1775 is given, and prior to the irinotecan dose on day 2 ]The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
- PK parameters of WEE1 inhibitor MK-1775 in terms of drug clearance [ Time Frame: Course 1 day 1 prior to the irinotecan infusion, prior to the MK-1775 dose, 4 hours after the dose of MK-1775 is given, and prior to the irinotecan dose on day 2 ]The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
- Response rate according to Response Evaluation Criteria in Solid Tumors [ Time Frame: Up to 1 year ]Response rates will be calculated as the percent of patients whose best response is a complete response (CR) or partial response (PR) and confidence intervals will be constructed according to the method of Chang. A responder is defined as a patient who achieves a best confirmed response of PR or CR on the study.
- Change in phosphorylated-cyclin-dependent kinase 1 (p-CDK1) levels [ Time Frame: Baseline up to 1 year ]Decreased p-CDK1 indicating Wee1 inhibition by WEE1 inhibitor MK-1775 will be investigated. These analyses will be descriptive and exploratory and hypotheses generating in nature.
- Predictive biomarkers of WEE1 inhibitor MK-1775 sensitivity [ Time Frame: Up to 1 year ]These analyses will be descriptive and exploratory and hypotheses generating in nature.
