Capecitabine, Temozolomide and Bevacizumab for Metastatic or Unresectable Pancreatic Neuroendocrine Tumors
This phase II trial studies the side effects and how well giving bevacizumab together with capecitabine and temozolomide works in treating patients with pancreatic neuroendocrine tumors that are metastatic or cannot be removed by surgery. 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. Drugs used in chemotherapy, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with combination chemotherapy may kill more tumor cells.

- RR % determined by RECIST v1.1 [ Time Frame: 18 months ] [ Designated as safety issue: No ]RR is defined as the proportion of patients with complete response + partial response (CR + PR] based on a patient's best response. The proportion of RR (CR+PR) will be estimated along with a one-sided lower 95% exact confidence bound to allow an informal assessment of the null hypothesis (RR=40%) based on binomial probabilities.
- Toxicities according to CTCAE v4.0 [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]Patients will be monitored for systemic, renal, gastrointestinal, hematologic, neurological and liver toxicities. Adverse events will be tabulated by organ system and severity. Proportions will be estimated along with 95% exact confidence intervals.
- PFS (median in months) [ Time Frame: 18 months ] [ Designated as safety issue: No ]
- OS (median in months) [ Time Frame: 18 months ] [ Designated as safety issue: No ]
- MGMT by central pathology review [ Time Frame: Baseline ] [ Designated as safety issue: No ]

Experimental: monoclonal antibody therapy, chemotherapy
Patients receive bevacizumab IV over 30-90 minutes on days 1 and 15, capecitabine PO BID on days 1-14, and temozolomide PO QD on days 10-14. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

I. To estimate if the combination of capecitabine and temozolomide with bevacizumab for metastatic or unresectable neuroendocrine tumors will improve response rate (RR) by 62% over historical controls (null RR of 40% to true RR 65%).
II. Assess the toxicities using Common Terminology Criteria for Adverse Events (CTCAE) v4.0.
I. To evaluate progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier analysis.
II. To assess O6-methyl guanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) by central pathology (path) review.
III. To assess serum hormone marker levels. IV. To evaluate computed tomography (CT) Perfusion as a tool to predict early therapeutic response. (Optional) V. To bank serum for future correlative analyses.
Patients receive bevacizumab intravenously (IV) over 30-90 minutes on days 1 and 15, capecitabine orally (PO) twice daily (BID) on days 1-14, and temozolomide PO once daily (QD) on days 10-14. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up patients are followed up for 1 year.
