PRIMARY OBJECTIVES:
I. To assess safety, tolerability and toxicity of SVN53-67/M57-KLH peptide vaccine (SurVaxM) in emulsion with incomplete Freund's adjuvant (montanide ISA 51) and given subcutaneously with sargramostim (granulocyte macrophage-colony-stimulating factor [GM-CSF]) in combination with a somatostatin analogue, octreotide acetate (Sandostatin LAR) in patients with survivin positive metastatic neuroendocrine tumors (NETs).
SECONDARY OBJECTIVES:
I. To determine clinical benefit (including complete response, partial response and stable disease as defined by Response Evaluation Criteria in Solid Tumors [RECIST] version [v]1.1) at 6 months, 9 months and 12 months from study entry.
II. To evaluate the immunogenicity of SurVaxM in NETs by measuring anti-survivin antibody levels and anti-tumor T-cell responses in peripheral blood.
III. To determine time to progression (TTP) compared to prior to study entry, in patients with metastatic NETs treated with SurVaxM.
EXPLORATORY OBJECTIVES:
I. To explore immune markers associated with clinical responses to SurVaxM in peripheral blood of NETs patients.
OUTLINE:
Patients receive a SVN53-67/M57-KLH peptide vaccine in incomplete Freund's adjuvant subcutaneously (SC) and sargramostim SC on day 0. Treatment repeats every 2 weeks for up to 4 doses in the absence of disease progression or unacceptable toxicity. Patients also receive octreotide acetate intramuscularly (IM) on day 0. Cycles of octreotide acetate repeat every 28 days for 1 year in the absence of disease progression or unacceptable toxicity. Patients who remain free of tumor progression at 6 months and do not develop any regimen-related toxicity or serious adverse events will be eligible to receive additional doses of the vaccine and sargramostim every 3 months, for up to 1 year from the start of treatment.
After completion of study treatment, patients are followed up for 3 months.

Experimental: Treatment (SVN53-67/M57-KLH peptide vaccine, octreotide)
Patients receive a SVN53-67/M57-KLH peptide vaccine in incomplete Freund's adjuvant SC and sargramostim SC on day 0. Treatment repeats every 2 weeks for up to 4 doses in the absence of disease progression or unacceptable toxicity. Patients also receive octreotide acetate IM on day 0. Cycles of octreotide acetate repeat every 28 days for 1 year in the absence of disease progression or unacceptable toxicity. Patients who remain free of tumor progression at 6 months and do not develop any regimen-related toxicity or serious adverse events will be eligible to receive additional doses of the vaccine and sargramostim every 3 months, for up to 1 year from the start of treatment.

- Incidence of adverse events of SVN53-67/M57-KLH peptide vaccine in combination with octreotide acetate in patients with neuroendocrine tumors [ Time Frame: Up to 15 months ]Will be assessed with National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Will consider a toxicity to be an adverse event that is possibly, probably or definitely related to treatment. The maximum grade of toxicity for each category of interest will be recorded for each patient and the summary results will be tabulated by category and grade. Will be quantified using the observed rates of the adverse events, serious adverse events (SAE) and regimen limiting toxicities. Toxicity rates will be described using upper 1-sided 95% Jeffreys binomial confidence intervals.
- Immunogenicity of SVN53-67/M57-KLH peptide vaccine [ Time Frame: Baseline up to 15 months ]Survivin-specific CD8+ responses will be measured individually at baseline, 12 weeks and end of-study. These measures will be summarized by descriptive statistics (means, medians, quartiles, etc.). Confidence intervals will be constructed for the median and the mean. Exploratory graphical analysis will be used to discover associations among variables.
- Immunogenicity of SVN53-67/M57-KLH peptide vaccine [ Time Frame: Baseline up to 15 months ]Anti-survivin antibody (humoral) responses will be measured individually at baseline, 12 weeks and end of-study. These measures will be summarized by descriptive statistics (means, medians, quartiles, etc.). Confidence intervals will be constructed for the median and the mean. Exploratory graphical analysis will be used to discover associations among variables.
- Rate of progression [ Time Frame: Up to 15 months ]Will be based on Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 on computed tomography scan and comparison rate prior to start of treatment.
- Clinical benefit [ Time Frame: Up to 12 months ]Will be assessed with RECIST v1.1. Clinical Benefit (CB) is defined as number of patients having best overall response as complete response (CR), partial response (PR) or stable disease (SD). The estimated distribution of CB will be plotted using Kaplan Meier curves and reported with median survival and 95% confidence intervals if available.
- Time to progression (TTP) [ Time Frame: From enrollment to first documented progression per RECISTv1.1, assessed up to 15 months ]The TTP of each patient will be compared to TTP prior to study entry. The analysis will be descriptive and reported separately for each patient.
- Overall response rate (ORR) [ Time Frame: Up to 15 months ]Measured by RECIST v1.1.
- Duration of response (DOR) [ Time Frame: Up to 15 months ]Measured by RECIST v1.1.
- Serum levels of chromogranin A, serotonin and 5-HIAA [ Time Frame: Baseline up to 15 months ]Exploratory graphical analysis will be used to discover associations among variables.
- Serum levels of serotonin and 5-HIAA [ Time Frame: Baseline up to 15 months ]Exploratory graphical analysis will be used to discover associations among variables
- Serum levels of 5-HIAA [ Time Frame: Baseline up to 15 months ]Exploratory graphical analysis will be used to discover associations among variables
