An Open-label, Multi-center, Expanded Access Study of Everolimus in Participants With Advanced Neuroendocrine Tumors (NETs) (Core Study) and an Extension Study to the Open-label, Multi-center, Expanded Access Study of Everolimus in Patients With Advanced NETs (E1)

* Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
* Platelets ≥ 100 x 109/L
* Hemoglobin \>9 g/dL
* Adequate liver function as shown by:
* Serum bilirubin ≤ 1.5 x upper limit of normal (ULN)
* Alanine transaminase (ALT) and aspartate transaminase (AST) ≤ 2.5 x ULN. Patients with known liver metastases with an AST and ALT ≤ 5 x ULN
* International normalized ratio (INR) \<1.3 (INR \<3 in patients treated with anticoagulants)
* Adequate renal function as shown by: Serum creatinine ≤ 1.5 x ULN
* Fasting serum cholesterol ≤ 300 mg/dL or ≤ 7.75 mmol/L and fasting triglycerides ≤ 2.5 x ULN
* Written informed consent obtained before any trial related activity and according to local guidelines.

Core Exclusion:

* Patients with poorly differentiated neuroendocrine carcinoma, high-grade neuroendocrine carcinoma, adenocarcinoid, goblet cell carcinoid and small cell carcinoma were not eligible.
* Following Amendment 1, patients with neuroendocrine tumors of GI or lung origin
* Cytotoxic chemotherapy, immunotherapy or radiotherapy within 4 weeks prior to enrollment
* Hepatic artery embolization within the last two months or cryoablation or radiofrequency ablation of hepatic metastasis within two months of enrollment
* Prior therapy with mTOR inhibitors (for example sirolimus, temsirolimus, everolimus)
* Patients with a known hypersensitivity to everolimus or other rapamycin analogs (sirolimus, temsirolimus) or to its excipients
* Patients receiving chronic treatment with immunosuppressives
* Uncontrolled diabetes mellitus as defined by fasting serum glucose \>1.5 x ULN
* Patients who had any severe and/or uncontrolled medical conditions such as:

Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction

* Age ≥18 years old
* Completion of the whole treatment period in the CRAD001K24133 study
* Neuroendocrine tumor of gastrointestinal or pulmonary origin (pancreatic neuroendocrine tumors are excluded)
* No tumor progression during therapy with everolimus during CRAD001K24133 study (checked via radiologically assessment)
* No intolerable toxicity during therapy everolimus, or during combination therapy of everolimus and somatostatin analogues
