Rilotumumab in Treating Patients With Persistent or Recurrent Ovarian Epithelial Cancer, Fallopian Tube Cancer, or Primary Peritoneal Cancer

A Phase II Evaluation of AMG 102 (Rilotumumab) (NSC #750009) in the Treatment of Persistent or Recurrent Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Carcinoma

This phase II trial studies how well rilotumumab works in treating patients with ovarian epithelial, fallopian tube, or primary peritoneal cancer that has failed to respond to other therapies (persistent) or has returned after a period of improvement (recurrent). Rilotumumab is a type of drug called a monoclonal antibody, and may interfere with the ability of tumor cells to grow and spread by targeting certain cells and blocking them from working.

PRIMARY OBJECTIVES:

I. To estimate 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) in patients with persistent or recurrent epithelial ovarian, fallopian tube, or primary peritoneal carcinoma.

SECONDARY OBJECTIVES:

I. To determine the frequency and severity of adverse events associated with treatment with AMG 102 (rilotumumab) as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE).

II. To determine the duration of progression-free survival (PFS) and overall survival (OS).

TERTIARY OBJECTIVES:

I. To explore the association between a panel of biomarkers (as assayed by immunohistochemistry and mutation analysis) and measures of response to treatment with AMG 102 (rilotumumab) and clinical outcome in archived tumor tissue.

II. To evaluate circulating pre- and post-treatment levels of hepatocyte growth factor/scatter factor and markers of angiogenesis and their association with response to treatment with AMG 102 (rilotumumab) and clinical outcome.

OUTLINE:

Patients receive rilotumumab intravenously (IV) over 30-60 minutes on days 1 and 14. Courses repeat every 4 weeks 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 recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal carcinoma; histologic confirmation of the original primary tumor is required via the pathology report

• All patients must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 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

• Patient 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 Gynecologic Oncology Group (GOG) protocol, if one exists; in general, this would refer to any active GOG Phase III protocol for the same patient population

• Patients who have received one prior regimen must have a GOG performance status of 0, 1, or 2

  • Patients who have received two prior regimens must have a GOG performance status of 0 or 1

• Recovery from effects of recent surgery, radiotherapy, or chemotherapy

• Major surgical procedures must have taken place > 30 days before enrollment; minor surgical procedures must have taken place > 14 days before enrollment; central venous catheter placement is allowed at any time prior to enrollment provided the patient has recovered and any surgical would has healed

• Patients should be free of active infection requiring antibiotics (with the exception of uncomplicated urinary tract infections [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 immunologic agents, must be discontinued at least three weeks prior to registration

• 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, high-dose therapy, consolidation, non-cytotoxic agents or extended therapy administered after surgical or non-surgical assessment

• 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 have received prior cytotoxic chemotherapy for management of recurrent or persistent disease, as defined above; however, patients are encouraged to enroll on second-line non-cytotoxic studies prior to receiving additional cytotoxic therapy

• Patients who have received only one prior cytotoxic regimen (platinum-based regimen for management of primary disease), must have a platinum-free interval of less than 12 months, or have progressed during platinum-based therapy, or have persistent disease after a platinum-based therapy

• Patients must NOT have received any non-cytotoxic therapy for management of recurrent or persistent disease; patients are allowed to receive, but are not required to receive, biologic (non-cytotoxic) therapy as part of their primary treatment regimen

• Absolute neutrophil count (ANC) greater than or equal to 1,500/mcl

• Platelets greater than or equal to 100,000/mcl

• Hemoglobin >= 9 g/dL

• 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]) less than or equal to 3 x ULN

• Alkaline phosphatase less than or equal to 2.5 x ULN

• PTT (partial thromboplastin time) =< 1.5 x ULN

• International normalized ratio (INR) =< 1.5 x ULN

• Neuropathy (sensory and motor) less than or equal to CTCAE grade 1

• Proteinuria: =< 1+ (urinalysis) or < 1 g/24 hrs (24 hour urine collection)
