Brief summary

This phase II trial studies how well pazopanib hydrochloride works in treating patients with uterine cancer that has come back or has not responded to treatment. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Pazopanib hydrochloride may also stop the growth of uterine cancer by blocking blood flow to the tumor.

Detailed description

PRIMARY OBJECTIVES: I. To assess the activity of pazopanib in patients with persistent or recurrent carcinosarcoma of the uterus as measured by the proportion of patients who survive progression-free for at least 6 months and the proportion of patients who have objective tumor response (complete or partial). SECONDARY OBJECTIVES: I. To determine the frequency and severity of adverse events as assessed by Common Terminology Criteria of Adverse Events version 4.0 (CTCAE v4.0). II. To determine the duration of progression-free survival and overall survival. OUTLINE: This is a multicenter study. Patients receive pazopanib hydrochloride 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 histologically confirmed uterine carcinosarcoma which is persistent or recurrent; acceptable histological type is defined as carcinosarcoma (malignant mixed müllerian tumor), homologous or heterologous type * 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 greater than or equal to 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI), or caliper measurement by clinical exam or greater than or equal to 20 mm when measured by chest x-ray * Lymph nodes must be greater than or equal to 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 protocol 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 (chemotherapy) directed at the malignant tumor, must be discontinued at least three weeks prior to registration * At least 4 weeks must have elapsed since the patient underwent any major surgery (e.g., major: hysterectomy, resection of a lung nodule - minor: central venous access catheter placement) * 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 are allowed to receive, but are not required to receive, one additional cytotoxic regimen for management of recurrent or persistent disease according to the following definition: * Cytotoxic regimens include any agent that targets the genetic and/or mitotic apparatus of dividing cells, resulting in dose-limiting toxicity to the bone marrow and/or gastrointestinal mucosa * Note: patients on this non-cytotoxic study are allowed to receive one additional cytotoxic chemotherapy regimen for management of recurrent or persistent disease, as defined above; however, due to the novel nature of biologic compounds, patients are encouraged to enroll on second-line non-cytotoxic studies prior to receiving additional cytotoxic therapy * Patients must have NOT received any non-cytotoxic chemotherapy for management of recurrent or persistent disease; prior hormonal therapy is permitted * Absolute neutrophil count (ANC) greater than or equal to 1,500/mcL * Platelets greater than or equal to 100,000/mcL * Hemoglobin level greater than or equal to 9 g/dL * Creatinine less than or equal to 1.5 x institutional upper limit of normal (ULN) * Urine protein/creatinine ratio (UPCR) must be less than 1 (or urinary protein less than 1.0 g/24 hours) * Bilirubin less than or equal to 1.5 x ULN (subjects with Gilbert syndrome and elevations of indirect bilirubin only are eligible) * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) less than or equal to 2.5 x ULN * Alkaline phosphatase less than or equal to 2.5 x ULN * Subjects who have BOTH bilirubin greater than ULN and AST/ALT greater than ULN are not eligible * Specifically, if bilirubin is greater than 1 x ULN but less than or equal to 1.5 x ULN, THEN the AST and ALT must be less than or equal to ULN for patient to be eligible; if AST and/or ALT are greater than 1 x ULN but less than or equal to 2.5 x ULN, THEN the bilirubin must be less than or equal to ULN for patient to be eligible * Prothrombin time (PT) such that international normalized ratio (INR) is less than or equal to 1.5 x ULN (or an in-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin) and a partial thromboplastin time (PTT) less than or equal to 1.5 x ULN * Patients with a history of hypothyroidism/hyperthyroidism must have had stable well-controlled thyroid function for a minimum of 2 months as a condition for eligibility and that all other patients must have normal baseline thyroid function tests (thyroid stimulating hormone \[TSH\], triiodothyronine \[T\]3, T4) * Patients must have the ability to understand and sign an approved informed consent and authorization permitting release of personal health information * Patients who have met the pre-entry requirements * Patients must be capable of taking and absorbing oral medications; a patient must be clear of the following: * Any lesion, whether induced by tumor, radiation or other conditions, which makes it difficult to swallow tablets * Prior surgical procedures affecting absorption including, but not limited to major resection of stomach or small bowel * Active peptic ulcer disease * Malabsorption syndrome * Patients must be capable of taking and absorbing oral medications * A patient must be clear of the following: * Any lesion, whether induced by tumor, radiation, or other conditions, which makes it difficult to swallow tablets * Prior surgical procedures affecting absorption including, but not limited to, major resection of stomach or small bowel * Active peptic ulcer disease * Malabsorption syndrome * Any concomitant medications that are associated with a risk of corrected QC (QTc) prolongation and/or Torsades de pointes should be discontinued or replaced with drugs that do not carry these risks, if possible;
