WEE1 Inhibitor MK-1775 and Irinotecan Hydrochloride in Treating Younger Patients With Relapsed or Refractory Solid Tumors
This phase I/II trial studies the side effects and best dose of WEE1 inhibitor MK-1775 and irinotecan hydrochloride in treating younger patients with solid tumors that have come back or that have not responded to standard therapy. WEE1 inhibitor MK-1775 and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
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
- 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.
- 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.
