Pasireotide and Everolimus in Treating Patients with Thyroid Cancer Refractory to Radioiodine
This trial is active, not recruiting.
|Treatments||everolimus, pasireotide, everolimus and pasireotide|
|Targets||somatostatin, mTOR, FKBP-12|
|Start date||November 2010|
|End date||October 2016|
|Trial size||90 participants|
|Trial identifier||NCT01270321, IRB00041909, WCI1777-09|
The purpose of this study is to determine the effectiveness of two anticancer drugs, everolimus and pasireotide, in patients with thyroid cancer when the cancer is no longer responding to treatment with radioiodine or where it is deemed unsafe for the patient to receive additional radioiodine treatment. The investigators also want to establish the best manner of taking the two medications when used together to treat thyroid cancer. In particular, the investigators want to know if it is better to give both at the same time or add a second medication after the first one has stopped working.
This study will also look at specific substances called biomarkers in your blood, and in the tumor tissue which are involved in the growth of tumor cells, and determine if the levels of these biomarkers are related to your response to treatment or development of side effects.
Everolimus, also known by the brand name, Afinitor, is a biologic drug approved by the Food and Drug Administration (FDA) for the treatment of kidney cancer. It works by preventing cancer cells from multiplying and it also makes them more likely to die from the treatment.
Pasireotide also known by the name, SOM230 is a new medication that is not yet approved by the FDA for the treatment of cancer. It is a newer form of a drug called octreotide, which is approved for the treatment of cancer arising from endocrine organs. Pasireotide works by binding to a protein called somatostatin receptor, which is expressed in many tissues throughout the body including thyroid cancer cells. Pasireotide prevents the action of somatostatin by binding to these receptors.

Response rate [(complete response (RR) + partial response (PR)]
time frame: After every 2 cycles on therapy
time frame: After every 2 cycles of treatment
Male or female participants at least 18 years old.
Inclusion Criteria: 1. Histologic or cytologic confirmation of thyroid cancer (papillary, follicular, medullary); histologic variants such as Hurthle and tall cell variants are allowed. 2. Biochemical or radiologic documentation of disease progression within the last 12 months prior to enrollment. 3. Presence of at least one site of measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1. 4. Patient must have radioiodine refractory disease as defined by one or more of the following conditions: - All cases of medullary thyroid carcinoma. - No iodine-uptake on a post- radioactive iodine treatment scan (in presence of low iodine diet and thyroid stimulating hormone (TSH) suppression) in an anatomically defined lesion that qualifies as target lesion by RECIST criteria. OR • If there is demonstrable iodine-uptake: the last radioiodine therapy of (≥ 100 mCi) was given within the last 16 months OR if given more than 16 months before enrollment, there is evidence of disease progression after each of the last two radioiodine treatment performed within 16 months of each other (each dose should be ≥ 100mCi). OR - If the patient has received the maximum cumulative life time dose of radioactive iodine treatments of at least 600 mCi. - If the patient declines or is intolerant of radioiodine therapy or if with progressive disease that is, in the opinion of the treating physician, likely to benefit from biologic therapy rather than further iodine therapy e.g. patient with heavy burden of disease 5. Age ≥ 18 years. 6. Minimum of four weeks since any major surgery or since completion of radiation (patients should have adequately recovered from the acute toxicities of any prior therapy). 7. Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2. 8. Life expectancy of at least 6 months. 9. Adequate bone marrow function as shown by: absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L, platelets ≥ 100 x 10⁹/L, Hgb > 9 g/dL. 10. Adequate liver function as shown by: serum bilirubin ≤ 1.5 x upper limit of normal (ULN), and serum transaminases activity ≤ 3 x ULN, with the exception of serum transaminases (< 5 x ULN) if the patient has liver metastases. 11. Adequate renal function as shown by serum creatinine ≤ 1.5 x ULN or glomerular filtration rate (GFR) of 60cc/ml using the formula of Cockroft and Gault. 12. 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. 13. Women of childbearing potential must have a negative serum pregnancy test within 14 days of the administration of the first study treatment. Women must not be lactating. Both men and women of childbearing potential must be advised of the importance of using effective birth control measures during the course of the study. 14. Signed informed consent to participate in the study must be obtained from patients after they have been fully informed of the nature and potential risks by the investigator (or his/her designee) with the aid of written information. 15. International normalized ratio (INR) and prothrombin time (PTT) ≤ 1.5 x ULN. (Anticoagulation is allowed if target INR ≤ 1.5 on a stable dose of warfarin or on a stable dose of low molecular weight [LMW] heparin for > 2 weeks at time of randomization.) Exclusion Criteria: 1.
