AZD1775 in Treating Patients With Advanced Refractory Solid Tumors With CCNE1 Amplification

Study Overview
=================
Brief Summary
-----------------
This phase II trial studies how well AZD1775 works in treating patients with solid tumors with CCNE1 amplification that have spread to other places in the body (advanced) and do not respond to treatment (refractory). AZD1775 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description
-----------------
PRIMARY OBJECTIVE: I. To evaluate the proportion of patients with the objective response rate (ORR) to adavosertib (AZD1775) in patients with advanced refractory cancers with CCNE1 amplification. SECONDARY OBJECTIVES: I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with AZD1775 in patients with advanced refractory cancers with CCNE1 amplification. II. To evaluate proportion of patients with extended time to progression (time to progression on AZD1775/ time to progression on last line of therapy >= 1.3). III. To evaluate time until death or disease progression. IV. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms. OUTLINE: Patients receive adavosertib orally (PO) once daily (QD) on days 1-5 and 8-12. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 4 weeks.
