A Phase 2 Study of AZD1775, a Wee1 Inhibitor, in Patients With CCNE1 Amplification

This phase II trial studies how well WEE1 inhibitor AZD1775 works in treating patients with
solid tumors with CCNE1 amplification that have spread to other places in the body and do not
respond to treatment. WEE1 inhibitor AZD1775 may stop the growth of tumor cells by blocking
some of the enzymes needed for cell growth.


I. To evaluate the proportion of patients with the objective response rate (ORR) to WEE1
inhibitor AZD1775 (AZD1775) in patients with advanced refractory cancers with CCNE1


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.


Patients receive WEE1 inhibitor AZD1775 orally (PO) once daily (QD) on days 1-5 and 8-12.
Courses 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.

Inclusion Criteria:

- Patients must have one of the histologically advanced solid tumors harboring CCNE1
amplification: their diseases are refractory to, or do not have, standard-of-care
therapy; or they declined standard-of-care therapy; patients with triple negative
breast cancer or small cell lung cancer are not eligible since there is an ongoing
phase Ib study of AZD1775 as a single agent targeting these patients; CCNE1
amplification is defined in a Clinical Laboratory Improvement Amendments

panel on the Ion Torrent PGM; or CCNE1 amplification on alternate CLIA platforms such
as Foundation One, UW-OncoPlex - Cancer Gene Panel, Memorial Sloan
Kettering-Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT),
Solid Tumor Genomic Assay (Life Technologies), etc. will also be eligible to be
treated after principle investigator (PI) approval; patients with known CCNE1
amplification on local or commercial platforms can start treatment after planned
biopsy or submission of recent archival sample; central next-generation sequencing
(NGS) CCNE1 and fluorescence in situ hybridization (FISH) testing will be performed to
confirm the result

contraception (i.e. condoms) for the duration of the study and for 3 months after
treatment stops
