Ixabepilone in Treating Patients With Recurrent or Persistent Uterine Cancer

Inclusion Criteria

• Patients must have histologically confirmed uterine carcinosarcoma which is persistent or recurrent with documented disease progression after appropriate local therapy; acceptable histologic type is defined as carcinosarcoma (malignant mixed muellerian tumor), homologous or heterologous type
• 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 at least one ?target lesion? to be used to assess response on this protocol as defined by RECIST version 1.1; 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 not be eligible for a higher priority Gynecologic Oncology Group (GOG) protocol, if one exists; in general, this would refer to any active GOG Phase III or Rare Tumor protocol for the same patient population
• Patients must have a GOG Performance Status of 0, 1, or 2
• Recovery from effects of recent surgery, radiotherapy, or chemotherapy
• Patients should be free of active infection requiring antibiotics (with the exception of uncomplicated urinary tract infection [UTI])
• Any hormonal therapy directed at the malignant tumor must be discontinued at least one week prior to registration
• Any other prior therapy directed at the malignant tumor, including biological and immunologic agents, must be discontinued at least three weeks prior to registration
• Patients must have had one prior chemotherapeutic regimen for management of carcinosarcoma; initial treatment may include chemotherapy, chemotherapy and radiation therapy, and/or consolidation/maintenance therapy; chemotherapy administered in conjunction with primary radiation as a radio-sensitizer WILL be counted as a systemic chemotherapy regimen
• Patients who have NOT received prior therapy with a taxane (such as paclitaxel or docetaxel) MUST receive a second regimen that includes a taxane
• Patients must have NOT received any additional cytotoxic chemotherapy except as noted above
• Patients are allowed to receive, but are not required to receive, one additional non-cytotoxic regimen for management of recurrent or persistent disease according to the following definition:
• Non-cytotoxic (biologic or cytostatic) agents include (but are not limited to) monoclonal antibodies, cytokines, and small-molecule inhibitors of signal transduction
• Absolute neutrophil count (ANC) greater than or equal to 1,500/mcl
• Platelets greater than or equal to 100,000/mcl
• Creatinine less than or equal to 1.5 x institutional upper limit normal (ULN)
• Bilirubin less than or equal to 1.5 x ULN
• Serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST]) and serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) less than or equal to 3 x ULN
• Alkaline phosphatase less than or equal to 2.5 x ULN
• Patients must have signed an approved informed consent and authorization permitting release of personal health information

Exclusion Criteria

• Neuropathy (sensory and motor) less than or equal to grade 1
• Patients who have met the pre-entry requirements
• Patients of childbearing potential must have a negative serum pregnancy test 72 hours prior to the study entry and be practicing an effective form of contraception
• Patients who have received prior therapy with Ixabepilone
• Patients with a known history of severe (Common Terminolog
