Dasatinib, Paclitaxel, and Carboplatin in Treating Patients With Stage III-IV or Recurrent Endometrial Cancer

Pilot and Translational Study of Dasatinib (NSC#732517) Paclitaxel and Carboplatin in Women With Advanced Stage and Recurrent Endometrial Cancer

This pilot phase I trial studies how well dasatinib works together with paclitaxel and carboplatin in treating patients with stage III, stage IV, or endometrial cancer that has come back after a period of improvement. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving dasatinib together with paclitaxel and carboplatin may kill more tumor cells.

PRIMARY OBJECTIVES:

I. To evaluate pMEK and EphA2 signaling effectors in pre- and post- treatment biopsy tissues from patients with advanced staged measurable primary or recurrent endometrial cancer.

SECONDARY OBJECTIVES:

I. To determine the frequency and severity of adverse events as assessed by Common Terminology Criteria for Adverse Events version 4 (CTCAE v. 4) of dasatinib administered in combination with paclitaxel and carboplatin in patients with advanced staged measurable primary or recurrent endometrial cancer.

II. To record the objective response rate by Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1.

III. To describe the progression-free survival and overall survival.

TERTIARY OBJECTIVES:

I. To explore the relationship of micro ribonucleic acid (RNA) 520d-3p (miR520d-3p) and EphA2 in pretreatment biopsies.

II. To evaluate downstream EphA2 signaling effectors, such as CAV-1, pAKT, FAK, paxillin, and p130cas in pre- and post-tissue treatment biopsies.

III. To explore the effect of dasatinib on the expression of other Eph family members such as EphB2 and EphB4.

IV. To quantify circulating tumor cells (CTCs) before and during the individual treatment phases.

OUTLINE:

Patients receive induction therapy comprising dasatinib orally (PO) once daily (QD) for 14 days. *Beginning 7 days later, patients receive paclitaxel intravenously (IV) over 3 hours and carboplatin IV on day 1, and dasatinib PO QD on days 1-21. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

NOTE: * Patients who have had prior external-beam pelvic or extended-field pelvic/para-aortic radiation therapy must receive treatment at a reduced dose.

After completion of study treatment, patients are followed up every 3 months for 1 year.

Inclusion Criteria:

• Patients must have measurable stage III, stage IV, or recurrent endometrial carcinoma whose potential for cure by surgery or radiation therapy alone is poor

• Patients with the following histologic epithelial cell types are eligible: endometrioid adenocarcinoma, serous adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, adenocarcinoma not otherwise specified (N.O.S.), mucinous adenocarcinoma, squamous cell, transitional cell carcinoma, and mesonephric carcinoma; uterine carcinosarcoma are not eligible for either COHORT

• All patients must have measurable disease; measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded); each lesion must be >= 20 mm when measured by conventional techniques, including palpation, plain x-ray, computed tomography (CT), and magnetic resonance imaging (MRI), or >= 10 mm when measured by spiral CT; measurable disease lesions must be amenable to pre- and post- treatment biopsy

• Patients must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST; tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy

• Patients must have a Gynecologic Oncology Group (GOG) performance status of 0 to 2

• Any other prior therapy directed at the malignant tumor, including immunologic agents, must be discontinued at least three weeks prior to registration

• Patients should have had NO prior chemotherapy agents for advanced or recurrent endometrial cancer; prior chemotherapy administration in conjunction with primary radiation therapy as a radiosensitizer would not exclude a patient from participation in this trial
