Summary

This randomized phase II trial studies how well paclitaxel when given together with or without pazopanib hydrochloride works in treating patients with ovarian epithelial, fallopian tube, or peritoneal cavity cancer that is persistent or has come back. Drugs used in chemotherapy, such as paclitaxel 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. Pazopanib hydrochloride may stop the growth of tumor cells by blocking blood flow to the tumor or by blocking some of the enzymes needed for cell growth. It is not yet known whether paclitaxel is more effective when given with or without pazopanib hydrochloride in treating ovarian epithelial, fallopian tube, and peritoneal cavity cancer.

Eligibility Criteria

Inclusion Criteria

  • Patients must have recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal carcinoma; histologic documentation of the original primary tumor is required via the pathology report
  • Patients must have measurable disease or non-measurable (detectable) disease
  • 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
  • Non-measurable (detectable) disease in a patient is defined in this protocol as one who does not have measurable disease but has at least one of the following conditions:
  • Ascites and/or pleural effusion attributed to tumor
  • Solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST 1.1 definitions for target lesions
  • Patients with measurable disease must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST 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 Gynecology 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; in addition, patients must not be eligible for the currently active phase II cytotoxic protocol in platinum resistant disease
  • Patients who have received one prior regimen must have a GOG performance status of 0, 1, or 2
  • Patients who have received two or three prior regimens must have a GOG performance status of 0 or 1
  • 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 chemotherapy, biological/targeted (non-cytotoxic) agents, and immunologic agents, must be discontinued at least three weeks prior to registration; chimeric or human or humanized monoclonal antibodies (including bevacizumab) or vascular endothelial growth factor (VEGF) receptor fusion proteins (including VEGF TRAP/aflibercept) must be discontinued for at least 12 weeks prior to registration
  • At least 4 weeks must have elapsed since the patient underwent any major surgery (e.g., major: laparotomy, laparoscopy, thoracotomy, video-assisted thorascopic surgery [VATS]); there is no restriction on minor procedures (e.g., minor: central venous access catheter placement, ureteral stent placement or exchange, paracentesis, thoracentesis)
  • Patients must have had one prior platinum-based chemotherapeutic regimen for management of primary disease containing carboplatin, cisplatin, or another organoplatinum compound; this initial treatment may have included intraperitoneal therapy, consolidation, biologic/targeted (non-cytotoxic) agents (e.g., bevacizumab), or extended therapy administered after surgical or non-surgical assessment; if patients were treated with paclitaxel for their primary disease, this can have been given weekly or every 3 weeks
  • Patients are allowed to receive, but are not required to receive, two additional cytotoxic regimens for management of recurrent or persistent disease, with no more than 1 non-platinum, non-taxane regimen; treatment with weekly paclitaxel for recurrent or persistent disease is NOT allowed
  • Patients a
