A Phase 2 interventional study of Bevacizumab and Everolimus in Advanced Pancreatic Neuroendocrine Tumor, Locally Advanced Pancreatic Neuroendocrine Tumor and Pancreatic Gastrinoma, sponsored by National Cancer Institute (NCI). Completed at 394 sites in 2 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-08-04.
Sponsored by National Cancer Institute (NCI) · Phase 2, Interventional, and Treatment
This randomized phase II trial studies how well everolimus and octreotide acetate with or without bevacizumab works in treating patients with pancreatic neuroendocrine tumors that cannot be removed by surgery and have spread nearby or to other places in the body. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Octreotide acetate may interfere with and slow the growth of tumor cells. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. 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 acetate together is more effective with or without bevacizumab in treating pancreatic neuroendocrine tumors.
PRIMARY OBJECTIVES:
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.
SECONDARY OBJECTIVES:
I. To compare progression-free survival (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: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive everolimus orally (PO) once daily (QD) on days 1-28 and octreotide acetate intramuscularly (IM) on day 1.
ARM II: Patients receive everolimus and octreotide acetate as in Arm I. Patients also receive bevacizumab intravenously (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 either histologic documentation of a pancreatic primary site, or clinical evidence of a pancreatic neuroendocrine primary tumor as determined by the treating physician
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 computed tomography (CT) scan
All other lesions, including small lesions (longest diameter \< 20 mm with conventional techniques or \< 10 mm with spiral CT scan) and truly non-measurable lesions; lesions that are considered non-measurable include the following:
Cystic lesions
Any prior treatment (with the exception of octreotide) must be completed at least 4 weeks prior to initiation of treatment
There is no limit on the prior number of procedures
Prior progression on somatostatin analogs or a negative octreotide scan does not exclude patient participation in this study
Insertion of a vascular access device is not considered major or minor surgery
Patients receive 28-day cycles until progression or unacceptable toxicity consisting of: everolimus 10 mg PO QD on days 1-28 and octreotide acetate 20 mg IM on day 1.

Progression Free Survival
Progression Free Survival (PFS) was defined as the time from study entry until disease progression or death, whichever occurs first. The median PFS was estimated using the Kaplan-Meier method. Progression was assessed per RECIST criteria, and defined as at least a 20% increase in the sum of the longest diameters of target lesions (and an absolute increase of at least 0.5 cm) or the appearance of new lesions.
Time frame: From study entry to the date of documented progression or death from any cause, up to 3 years
Overall Response Rate
The proportion of patients who respond (completely or partially) to each combination regimen will be estimated. Response was defined using Response Evaluation Criteria In Solid Tumors (RECIST) criteria: Complete Response (CR): disappearance of all target lesions; Partial Response (PR) 30% decrease in sum of longest diameter of target lesions.
Time frame: Up to 3 years
Overall Survival (OS)
Overall survival (OS) is defined as the time from study entry to death from any cause. The median OS was estimated using the Kaplan-Meier method.
Time frame: From registration to time of death, assessed up to 3 years
From October 2010 to October 2012, 150 participants were recruited and randomized to study treatment.
