To determine frequency of any grade of stomatitis at day 29 (cycle 2, day 1) in patients receiving dose-adjusted everolimus.
- Progression-free survival rates at 6 months.
- Pharmacodynamic (PD)-inhibition of downstream mammalian target of rapamycin (mTOR) effectors in peripheral blood.
- Number of dose adjustments required.
- Percentage of days on therapy.
- Average minimum concentration (Cmin) values.
- Frequency and type of treatments for stomatitis.
- Genetic predictors of stomatitis development in selected outlier patients.
Patients receive everolimus orally (PO) daily on days 1-28. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients also undergo real-time pharmacokinetic therapeutic drug monitoring (TDM) on days 4, 8, and 15 of course 1. Dosing adjustments of everolimus will be performed on day 8, if necessary. If the everolimus dose is adjusted, patients will continue to undergo real-time pharmacokinetic TDM weekly until goal concentrations are achieved on 2 consecutive measures. Patients whose everolimus dose is not adjusted undergo real-time pharmacokinetic TDM on day 1 of courses 2-6.
After completion of study treatment, patients are followed up every 12 weeks.

Experimental: Supportive care (real-time pharmacokinetic TDM of everolimus)
Patients receive everolimus PO daily on days 1-28. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients also undergo real-time pharmacokinetic TDM on days 4, 8, and 15 of course 1. Dosing adjustments of everolimus will be performed on day 8, if necessary. If the everolimus dose is adjusted, patients will continue to undergo real-time pharmacokinetic TDM weekly until goal concentrations are achieved on 2 consecutive measures. Patients whose everolimus dose is not adjusted undergo real-time pharmacokinetic TDM on day 1 of courses 2-6.
- Incidence of Stomatitis [ Time Frame: Day 29 ]Stomatitis graded rates and severity will be evaluated and recorded per World Health Organization and Common Terminology Criteria for Adverse Events criteria in the study population.
- Progression Free Survival (PFS) [ Time Frame: 6 months ]PFS will be evaluated based on rates of cancer progression and time to progression in the population. Progression will be determined using standard RECIST criteria. The median PFS for this study will be estimated by Kaplan-Meier method along with 95% confidence interval.
- Downstream Markers of Mammalian Target of Rapamycin (mTOR) Function Measured in Peripheral Blood Mononuclear Cells [ Time Frame: Up to day 15 of course 1 ]Pharmacodynamics will be evaluated for phosphorylated and non-phosphorylated ribosomal protein S6 kinase, protein kinase B, and eukaryotic translation initiation factor 4E-binding protein 1.
- Percentage of Days on Therapy [ Time Frame: Up to 6 months ]Percentage of days on therapy will be calculated using the formula: (expected - actual days)/expected x 100.
- Dose Interruptions and Adjustments [ Time Frame: Up to 6 months ]Dose interruptions and adjustments will be made on a per subject basis and total for the population.
- Frequency of Treatments for Stomatitis [ Time Frame: Up to 6 months ]Frequency of treatments for stomatitis will be collection of prescription and non-prescription interventions.
- Type of Treatments for Stomatitis [ Time Frame: Up to 6 months ]Type of treatments for stomatitis will be collection of prescription and non-prescription interventions.
- Response Rate Assessed Using Response Evaluation Criteria in Solid Tumors (RECIST) Criteria [ Time Frame: Up to 24 weeks ]Response rate will be measured at different time points, e.g. 8, 16, and 24 weeks, and will be summarized as percentage of stable disease, complete remission or partial remission along with 95% confidence interval.

- Progressive neuroendocrine tumors of pancreatic origin (PNET) that is unresectable, locally advanced or metastatic
- Advanced renal cell carcinoma (RCC) after failure of treatment with sunitinib or sorafenib
- Histologically confirmed, measurable or evaluable disease. Patients should have at least one measurable lesion.
Adequate bone marrow function as indicated by the following:
- Absolute neutrophil count (ANC) > 1,500/μL
- Platelets ≥ 100,000/μL
- Hemoglobin > 10 g/dL
- Adequate renal function, as indicated by creatinine clearance > 30 mL/min
Adequate liver function, as indicated by:
- Bilirubin ≤ 1.5 x upper limit of normal (ULN)
- International normalized ratio (INR) ≤ 2
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) < 2 x ULN unless related to primary disease
- Signed informed consent
- Adequate birth control when appropriate
- Fasting serum cholesterol ≤ 300 mg/dL OR ≤ 7.75 mmol/L AND fasting triglycerides ≤ 2.5 x ULN. NOTE: in case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication.
