This phase II trial studies how well dasatinib works in treating patients with ovarian, fallopian tube, endometrial, or peritoneal cancer that has come back or is persistent. Dasatinib may shrink patients' tumors by blocking some of the enzymes needed for cell growth.
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.

Proportion of Patients With Objective Tumor Response Rate (Complete Response [CR] or Partial Response [PR]) Using RECIST Version 1.1
Complete and Partial Tumor Response by RECIST 1.1. RECIST 1.1 defines complete response as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm and the disappearance of all non-target lesions and normalization of tumor marker level. Partial response is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Only those patients who have measurable disease present at baseline, have received at least one cycle of therapy, and have had their disease re-evaluated will be considered evaluable for response. These patients will have their response classified according to the definitions stated above. Complete and partial responses are included in the objective tumor response rate.
Time frame: CT scan or MRI if used to follow lesion for measurable disease every other cycle for the first 6 months; then every 3 months x 2; then every 6 months thereafter until disease progression for up to 5 years.
Duration of Overall Survival (OS)
Overall survival is defined as the duration of time from study entry to time of death or the date of last contact.
Time frame: Every cycle during treatment, then every 3 months for the first 2 years, then every six months for the next three years and then annually for the next 5 years.
Duration of Progression-free Survival (PFS)
PFS will be characterized with Kaplan-Meier plots and estimates of the median time until death or progression.
Time frame: Duration of time from start of treatment to time of progression or death, whichever occurs first, assessed up to 5 years
Incidence of Adverse Effects as Assessed by Common Terminology Criteria for Adverse Events Version 4.0
The frequency and severity of all toxicities are tabulated.
Time frame: Up to 5 years
