Dasatinib in Treating Patients With Recurrent or Persistent Ovarian, Fallopian Tube, Endometrial or Peritoneal Cancer

PRIMARY OBJECTIVES:

I. To assess the clinical activity of dasatinib in patients with recurrent or persistent
ovarian, fallopian tube, primary peritoneal, and endometrial clear cell carcinoma using
objective tumor response (complete and partial): in patients without loss of BRG-associated
factor 250a (BAF250a) expression and in patients with loss of BAF250a expression.

SECONDARY OBJECTIVES:

I. To examine the nature and degree of toxicity in this patient population treated with this
regimen in patients with and without loss of BAF250a expression.

II. To examine the progression-free survival and overall survival for this patient
population receiving dasatinib in patients with and without loss of BAF250a expression.

TERTIARY OBJECTIVES:

I. To examine the agreement between BAF250a immunohistochemistry and AT rich interactive
domain 1A (SWI-like) (ARID1A) mutation status using next generation sequencing performed in
formalin-fixed, paraffin-embedded tumor tissue.

OUTLINE:

Patients receive dasatinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28
days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and
then every 6 months for 3 years.

Inclusion Criteria:

- Patients must have recurrent or persistent ovarian, fallopian tube, peritoneum, and
endometrial clear cell carcinoma; primary tumors must be at least 50% clear cell
histomorphology in order to be eligible or have a histologically documented
recurrence with at least 50% clear cell histomorphology; in addition, the tumors
should be negative for expression of Wilms tumor 1 (WT-1) antigen (with the exception
of endometrial cancers where WT-1 stains are not required) and estrogen receptor (ER)
antigen by immunohistochemistry; focal, weak, ER staining of tumor cells (< 5%) is
permitted; appropriate tissue sections must be available for histologic evaluation
for central pathology review by Gynecologic Oncology Group (GOG); immunohistochemical
stained slides for ER and WT-1 antigen must be available for review by GOG

- If the primary tumor had at least 50% clear cell histomorphology, a biopsy of
the recurrent or persistent tumor is not required; however, immunohistochemical
studies of the primary tumor for ER and WT-1 antigens should be performed and
the slides submitted to the GOG for review; the percentage of clear cell
histomorphology must be documented in the pathology report or in an addendum to
the original report; if slides of the primary tumor are not available for review
due to disposal of slides by the histology laboratory (typically 10 years after
diagnosis), biopsy of recurrent or persistent disease is required

- If the primary tumor had less than 50% clear cell histomorphology (or if slides
of the primary tumor are not available for review), a biopsy of the recurrent or
persistent tumor is required to confirm at least 50% clear cell histomorphology
and lack of immuno-reactivity for ER and WT-1 antigens by immunohistochemistry;
the percentage of involvement must be documented in the pathology report or in
an addendum to the original report

- Patients must have results from the determination of BAF250a immunohistochemistry
(IHC) status and must have a BAF250a expression status that is currently open to
enrollment

- All patients must have measurable disease; measurable disease is defined by Response
Evaluation Criteria in Solid Tumors (RECIST) (version 1.1); measurable disease is
defined as at least one lesion that can be accurately measured in at least one
dimension (longest diameter to be recorded); each lesion must be >= 10 mm when
measured by computed tomography [CT], magnetic resonance imaging [MRI] or caliper
measurement by clinical exam; or >= 20 mm when measured by chest x-ray; lymph nodes
must be > 15 mm in short axis when measured by CT or MRI

- Patients must have had one prior platinum-based chemotherapeutic regimen for
management of primary disease; patients are allowed to receive, but are not required
to receive, two additional cytotoxic regimens for management of recurrent or
persistent disease

- Patients must be >= 3 weeks from last chemotherapy or radiation (6 weeks for
nitrosoureas or mitomycin)

- Patients must have progressed on, be ineligible for, or have declined participation
in GOG-0254 provided that protocol is actively accruing patients

- Leukocytes >= 3,000/mcL

- Absolute neutrophil count >= 1,500/mcL

- Platelets >= 100,000/mcL

- Creatinine =< 1.5 times the upper limit of normal (ULN) OR creatinine clearance >= 60
mL/min/1.73 m^2

- Bilirubin =< 1.5 ULN

- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and
alanine aminotransferase ALT (serum glutamate pyruvate transaminase [SGPT]) =< 3 x
ULN

- Patients who are on concomitant medications that are STRONG inducers or inhibitors of
the cytochrome P450 family 3, subfamily A, polypeptide 4 (CYP3A4) enzyme should stop
2 weeks prior to first dose of dasatinib, if all other eligibility has been confirmed

- Corrected QT (QTc) interval on electrocardiogram must be =< 480 msec (Fridericia
correction)

- Patients who have received one prior regimen must have a GOG performance status of 0,
1 or 2; patients who have received two or more prior regimens must have GOG
performance status of 0 or 1

- Patients who have met the pre-entry requirements

- Patients must have signed an approved informed consent and authorization permitting
release of personal health information

Exclusion Criteria:

- Prior treatment with dasatinib, imatinib or nilotinib

- Patients with symptomatic effusions (pleural, pericardial, or peritoneal) and/or
those who have required a procedure for symptomatic effusions within 4 weeks of start
of dasatinib are ineligible

- Patients with a history of cardiac disease including: (1) uncontrolled angina,
congestive heart failure, or myocardial infarction within six months prior to study
entry, (2) congenital long QT syndrome, (3) clinical significant ventricular
arrhythmias

- The concomitant use of histamine (H)2 blockers and proton pump inhibitors (PPIs) with
dasatinib is not recommended; the use of antacids should be considered in place of H2
blockers or proton pump inhibitors in patients receiving dasatinib therapy; if
antacid therapy is needed, the antacid dose should be administered two hours before
or after the dose of dasatinib; patients who cannot tolerate discontinuation of H2
blockers or PPIs are ineligible

- Therapeutic anticoagulation is not contraindicated, but for those patients on
therapeutic anticoagulation, alteration in coagulation parameters is expected
following initiation of dasatinib; for patients on therapeutic anticoagulation,
coagulation parameters should be assessed weekly for the first cycle following
initiation of dasatinib, weekly for the first cycle following a dose reduction, and
weekly for a minimum of two weeks after stopping dasatinib

- Patients whose circumstances do not permit completion of the study or the required
follow-up

- Patients who are pregnant or nursing; women of child-bearing potential must agree to
use adequate contraception (hormonal or barrier method of birth control; abstinence)
prior to study entry and for the duration of study participation and for 3 months
after completion of therapy; should a woman become pregnant or suspect she is
pregnant while she or her partner is participating in this study, she should inform
her treating physician immediately; a negative serum pregnancy test within 72 hours
of starting drug is required

years or whose previous cancer treatment contraindicates this protocol therapy

- Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral
therapy are ineligible

- Patients who are unable to swallow pills
