Primary Outcome Measures	Measure Description	Time Frame
Number of Participants With Dose Limiting Toxicities - Phase I	Tolerability of X-82 in combination with everolimus will be determined by NCI Common Terminology Criteria for Adverse Events (CTCAE version 4.0)	Completion of 1st cycle for all patients in Phase I portion of study (completed in approximately 20 months)
Overall Toxicities - Phase I	-Toxicities will be graded by the NCI Common Terminology Criteria for Adverse Events (CTCAE version 4.0)	30 days after completion of treatment (estimated to be 13 months)
Recommended Phase II Dose of X-82		Completion of 1st cycle for all patients in Phase I portion of study (completed in approximately 20 months)
Objective Response Rate (Complete Response + Partial Response) - Phase II	Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.	Through completion of treatment (estimated to be 12 months)

Secondary Outcome Measures	Measure Description	Time Frame
Disease Stabilization Rate - Phase II	* Disease stabilization rate is defined as the proportion of patients achieving a best overall response of complete response, partial response, or stable disease. * Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. * Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. * Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits.	Through completion of treatment (estimated to be 12 months)
Progression Free Survival (PFS) - Phase II	* PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. * Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.	Up to 3 years
Overall Survival - Phase II	Start of the treatment until death.	Up to 3 years
Number of Participants With Toxicity - Phase II	Toxicity will be graded by NCI Common Terminology Criteria for Adverse Events (CTCAE version 4.0)	Through 30 days after completion of treatment (estimated to be 13 months)

Histologic documentation of well differentiated or moderately differentiated locally unresectable or metastatic pancreatic neuroendocrine tumor from either a primary or metastatic site with documented disease progression ≤ 12 months prior to enrollment whose disease is not currently amenable to surgery, radiation, or other modality therapy with curative intent. If different histologic classification schemes are used, equivalent histologic classifications (for example "grade 1," "low grade," or "intermediate grade") are allowed. There must be histologic documentation of a pancreatic primary site or clinical evidence of a pancreatic neuroendocrine primary tumor as determined by the treating physician. Documentation from a metastatic site is sufficient if there is clinical evidence of a pancreatic primary site.
