Summary
This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug, Ziv-aflibercept, is being studied. It also means that the FDA has not yet approved Ziv-aflibercept for use in patients with your type of cancer. Every person has molecules in their bloodstream called vascular endothelial growth factors (VEGFs). These molecules help grow and sustain new blood vessels needed by the human body. Cancer tumors hijack this mechanism because they need new blod vessels and oxygen to grow. Ziv-aflibercept is an antibody. Antibodies are proteins that are produced naturally in our bodies and help to recognize foreign substances in our body. Ziv-aflibercept is a "targeted therapy" called a "VEGF Trap", that "traps" (binds) these VEGFs and prevents the cancer from using them to grow. Though Ziv-aflibercept has not yet been FDA approved for the treatment of carcinoid tumors, it has recently been approved for patients with treatment-resistant colorectal cancer. In this research study, we will use Ziv-aflibercept in combination with standard octreotide therapy to see if it slows the growth or spread of your carcinoid tumor. Standard octreotide (sandostatin) therapy is currently approved for treating symptoms of carcinoid tumors, such as those caused by carcinoid syndrome. Carcinoid syndrome is caused by hormones and other substances released by carcinoid tumors into the bloodstream. One of these secreted substances is serotonin, one of the body's natural chemical messengers. When excess serotonin secreted by the carcinoid tumors reaches the body's tissues, it is thought to cause diarrhea and redness (flushing) of the face, chest or back. Excess serotonin may also cause changes in the structure of the heart valves, which can impair the heart's function. Octreotide works by binding to receptors found on carcinoid tumors and prevents the release of hormones from the tumor.

Criteria
Inclusion Criteria:

- Histologically confirmed well differentiated or moderately differentiated
neuroendocrine tumor from either a primary or metastatic site

- Must have disease that is not amenable to curative resection

- Must have evidence of disease progression within 12 months prior to study entry

- Must have measurable disease (RECIST 1.1)

- Prior chemoembolization of local ablative therapies are allowed, provided there is
measurable disease outside of the area treated, or documented evidence of progression
at the site of prior treatment

- No limit to number of prior treatments. Prior bevacizumab allowed unless discontinued
due to unacceptable toxicity. Prior TKI targeting VEGF receptors allowed

- Treatment with a somatostatin analog required for all subjects

- Subjects with history of hypertension must be adequately controlled

- Therapeutic anticoagulation is allowed. Must be on a stable dose of anticoagulant
medication

- Must agree to use adequate contraception prior to study entry, for the duration of
study participation and for 3 months after last administration of study drug

Exclusion Criteria:

- Prior treatment including chemoembolization within 4 weeks of study entry

- Major surgery within 4 weeks of study entry or minor surgery within 2 weeks of study
entry

- Pregnant or breastfeeding

- Poorly differentiated carcinoma, high grade neuroendocrine tumor or small cell
carcinoma

- Prior treatment with Ziv-aflibercept

- Pancreatic neuroendocrine tumor (islet cell carcinoma)will be excluded from this
study. All non functional and functional islet cell carcinomas such as insulinoma,
glucagonoma, gastrinoma, VIPoma will be excluded.

- Not adequately recovered from toxicity of previous therapy

- Known untreated brain or other central nervous system metastases

- Known allergy to any of the study agents or to compounds of similar chemical or
biologic composition

- History of congestive heart failure

- Symptomatic peripheral arterial disease

- Unhealed wounds, ulcers or bone fractures

- HIV positive or active Hepatitis infection

- History of abdominal fistula, GI perforation, intra abdominal abscess, uncontrolled GI
bleeding, diverticulitis within 6 months of study entry

- History of arterial thrombotic events such as myocardial infarction, unstable angina
pectoris or any ischemic or hemorrhagic cerebrovascular accident within the past 6
months

- No history of pulmonary embolism, DVT or vascular access related thrombosis if not
also receiving adequate anticoagulation at a stable dose.

- No history of prior or synchronous malignancy except if treated with curative intent
at least 3 years prior to study entry, or adequately treated non-melanoma skin cancer,
cervical carcinoma in situ, or prostate intraepithelial neoplasia without evidence of
prostate cancer

- Uncontrolled non-malignant illness that may increase the risks associated with study
participation or may interfere with the conduct of the study or interpretation of
study results

- Uncontrolled psychiatric illness or social situations that would limit compliance with
study requirements
