This randomized phase II trial is studying how well giving everolimus and octreotide together with or without bevacizumab works in treating patients with locally advanced or metastatic pancreatic neuroendocrine tumors that cannot be removed by surgery. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Octreotide may interfere with and slow the growth of tumor cells. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab and everolimus also may stop the growth of pancreatic neuroendocrine tumors by blocking blood flow to the tumor. It is not yet known whether giving everolimus and octreotide together is more effective with or without bevacizumab in treating pancreatic neuroendocrine tumors.
Further Study Information
l. To assess the progression-free survival rate of patients with locally advanced or metastatic pancreatic neuroendocrine tumors treated with everolimus alone or everolimus plus bevacizumab.
I. To compare PFS among treatment arms shown to be efficacious. II. To estimate the overall tumor response rate in patients with metastatic pancreatic neuroendocrine tumors treated with one of two novel regimens.
III. To estimate the overall biochemical response rate (as measured by plasma chromogranin A levels) in patients with metastatic pancreatic neuroendocrine tumors treated with these regimens.
IV. To assess the toxicity of each regimen in patients with metastatic pancreatic neuroendocrine tumors.
V. To assess the overall survival of patients with pancreatic neuroendocrine tumors treated with these regimens.
OUTLINE: This is a multicenter study. Patients are stratified according to prior treatment with cytotoxic chemotherapy (no vs yes), prior use of octreotide (no vs yes), and prior therapy with sunitinib (no vs yes). Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive oral everolimus once daily on days 1-28 and intramuscular octreotide LAR on day 1.
ARM II: Patients receive everolimus and octreotide LAR as in arm I. Patients also receive bevacizumab IV over 30-90 minutes on days 1 and 15.
In both arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3-6 months for 3 years.
- Patients must have histologic documentation of well-differentiated or moderately differentiated neuroendocrine tumor from either a primary or metastatic site
- If different histologic classification schemes are used, equivalent histologic classifications (for example "grade 1", "low-grade", or "intermediate-grade") are allowed
- Patients with poorly differentiated neuroendocrine carcinoma or small cell carcinoma are excluded
- Documentation from a metastatic disease site is sufficient if there is clinical evidence of a pancreatic primary site
- Locally unresectable or metastatic disease
- Patients must have either histologic documentation of a pancreatic primary site, or clinical evidence of a pancreatic neuroendocrine primary tumor as determined by the treating physician
- Patients with neuroendocrine tumors (e.g., gastrinoma, VIPoma) in whom a pancreatic or peripancreatic primary site is strongly suspected are also eligible
- Patients must have evidence of disease (measurable or non-measurable) with evidence of progression within the past 12 months
- Measurable disease is defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 2 cm with conventional techniques or as ≥ 1 cm with spiral CT scan
- Non-measurable disease is defined as all other lesions, including small lesions (longest diameter < 20 mm with conventional techniques or < 10 mm with spiral CT scan) and truly nonmeasurable lesions
- Lesions that are considered non-measurable include the following:
- Bone lesions
- Leptomeningeal disease
- Pleural/pericardial effusion
- Inflammatory breast disease
- Lymphangitis cutis/pulmonis
- Abdominal masses that are not confirmed and followed by imaging techniques
- Cystic lesions
- Treatment with somatostatin analogs is a requirement of the study
- Patients receiving octreotide at the time of study entry may continue at the same dose level for the duration of the study
- Patients not receiving octreotide will initiate treatment according to study guidelines
- Prior progression on somatostatin analogs or a negative octreotide scan does not exclude patient participation in this study
- No clinical evidence of brain metastases or carcinomatous meningitis
- ECOG performance status 0-1
- Granulocytes >= 1,500/uL
- Platelets >= 100,000/uL
- Creatinine =< 1.5 x upper limit of normal (ULN)
- Bilirubin =< 1.5 x ULN
- ALT and AST =< 2.5 x ULN (=< 5 x ULN if liver metastases present)
- Urine protein =< 1+ OR urine creatinine ratio < 1 by urinalysis (if UPC ratio is > 1 on urinalysis, then 24-hour urine collection for protein must be obtained and level must be < 1,000 mg for patient enrollment
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception during study treatment
- No concurrent condition resulting in immune compromise, including chronic treatment with corticosteroids or other immuno suppressive agents
- No active or severe liver disease (e.g., acute or chronic hepatitis, cirrhosis); no positive anti-HBV; HBV seropositive patients (HBsAg positive) are eligible if they are closely monitored for evidence of active HBV infection by HBV DNA testing, and they agree to receive suppressive therapy with lamivudine or other HBV-suppressive therapy until at least 4 weeks after the last dose of everolimus; patients who are hepatitis C antibody positive are eligible provided that hepatitis C viral load (hepatitis C RNA) is undetectable
- No history of GI perforation within 12 months prior to registration
- No history of clinically significant bleeding episodes
- Patients with a history of hypertension must be adequately controlled (baseline BP < 150/90 mm Hg) on antihypertensives
- No current congestive heart failure (New York Heart Association Class II, III, or IV)
- No symptomatic arterial peripheral vascular disease
- No history of aortic aneurysm, aortic dissection, angina, myocardial infarction, stroke, or other arterial thrombotic events within 6 months of registration
- No uncontrolled diabetes mellitus
- Patients with a history of severely impaired lung function as defined as spirometry and DLCO that is 50% of the normal predicted value and/or O_2 saturation that is 88% or less at rest on room air are excluded
- Patients with fasting serum cholesterol >= 300 mg/dL OR >= 7.75 mmol/L AND fasting triglycerides >= 2.5 X ULN should initiate lipid-lowering medications with the goal of achieving levels below these thresholds
- No history of intolerance or allergies to octreotide
- No concurrent palliative radiotherapy
- No prior treatment with bevacizumab, everolimus, or other mTOR inhibitors
- Other prior treatments, including but not limited to prior cytotoxic chemotherapy, alpha interferon, tyrosine kinase inhibitors, external beam radiation therapy, and radiopeptide therapy are allowed
- There is no limit on the number of prior treatment regimens
- Any prior treatment (with the exception of octreotide) must be completed at least 4 weeks prior to initiation of treatment
- Prior treatment with embolization or ablative therapies is allowed if measurable disease remains outside of the treated area
- There is no limit on the prior number of procedures
- Patients should have completed any major surgery ≥ 4 weeks from start of treatment
