Study was stopped for severe toxicity causing concern for patients

RATIONALE: AMG 706 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

PURPOSE: This phase II trial is studying how well AMG 706 works in treating patients with persistent or recurrent ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer.

OBJECTIVES:

Primary

• To assess the activity of AMG 706, in terms of the frequency of patients with progression-free survival for at least 6 months after initiating therapy or with an objective tumor response, in patients with persistent or recurrent ovarian epithelial, fallopian tube, or primary peritoneal carcinoma.

Secondary

• To determine the frequency and severity of adverse events as assessed by CTCAE v3.0.
• To characterize the distribution of the progression-free and overall survival of these patients.

OUTLINE: This is a multicenter study.

Patients receive oral AMG 706 once daily 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 every 3 months for 2 years and then every 6 months for 3 years.

DISEASE CHARACTERISTICS:

• Histologically confirmed ovarian epithelial, fallopian tube, or primary peritoneal carcinoma

  • Recurrent or persistent disease

• Measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded) as ≥ 20 mm by conventional techniques or as ≥ 10 mm by spiral CT scan

  • Must have at least one "target lesion" that can be used to assess response, as defined by RECIST criteria

    • Tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented OR a biopsy is obtained to confirm persistent disease ≥ 90 days following completion of radiotherapy

• Must have received one prior platinum-based chemotherapeutic regimen containing carboplatin, cisplatin, or another organoplatinum compound for management of primary disease

  • Initial treatment may have included high-dose therapy, consolidation therapy, or extended therapy administered after surgical or non-surgical assessment
  • One additional cytotoxic regimen for management of recurrent or persistent disease allowed
  • Patients must have a platinum-free interval of < 12 months, have progressed during platinum-based therapy, or have persistent disease after a platinum-based therapy

• Ineligible for a higher priority GOG protocol

• No pleural effusion or ascites causing grade 2 or greater dyspnea

• No history of uncontrolled CNS metastases

• No average systolic blood pressure ≥ 150 mm Hg and average diastolic blood pressure ≥ 90 mm Hg

  • Patients with hypertension that is stable on a current dose of anti-hypertensives are eligible

• No history of impaired cardiac status (e.g., severe heart disease, cardiomyopathy, or congestive heart failure)
