SOM230 Alone or in Combination With RAD001 in Patients With Medullary Thyroid Cancer

Inclusion Criteria:

* Patients with progressive metastatic or postoperative persistent medullary thyroid cancer who have histopathologically confirmed disease and measurable tumor lesions. (Postoperative persistent after surgical removal is characterized by increased levels of calcitonin with or without radiological detectable tumour relapse or metastases.)
* Patients with evidence of biochemical progression of disease, as expressed by progressive increase of serum calcitonin levels, assessed once a month for at least three months before study entry, according to RECIST definitions (elevation of the markers for at least 25 %).
* Disease that is not amenable to surgery, radiation, or combined modality therapy with curative intent.
* Adequate organ function - Karnofsky-Index performance status \>60%
* Life expectancy \> 6 months
* Age \> 18 years
* Women of childbearing potential must have a negative serum pregnancy test within 14 days of randomization and a urine pregnancy test 48 hours prior to the administration of the first study treatment.
* Patients with a known history of impaired fasting glucose or diabetes mellitus (DM) may be included, however blood glucose and antidiabetic treatment must be monitored closely throughout the trial and adjusted as necessary.
* Signed and dated informed consent document indicating that the patient has been informed of all pertinent aspects of the trial prior to enrolment.

Exclusion Criteria:

* Unstable systemic diseases including uncontrolled hypertension, active uncontrolled infections, psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for entry into this study.
* Known hypersensitivity to somatostatin analogues.
* Pregnant or breast-feeding patients
* Sign of recurrence of prior or concomitant malignancies (within the last 3 years or requiring active treatment) other than MTC; with the exception of previous basal cell skin cancer, previous cervical carcinoma in situ
* Prior therapy with mTOR inhibitors (e.g. sirolimus, temsirolimus, everolimus)
* Participation in a clinical trial to test an investigational drug within 4 weeks prior to visit 1.
* Any of severe and/or uncontrolled medical conditions:
* Patients who have congestive heart failure (NYHA Class III or IV), unstable angina, sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block or a history of acute myocardial infarction within the six months preceding enrollment,
* QT related exclusion criteria
* Previous treatments with chemotherapy, loco regional therapy (eg, chemoembolization) or interferon are permitted providing that toxicity has resolved to \< Grade 1 at study entry and that last treatment was at least 4 weeks prior to baseline assessment.
