Pasireotide, Everolimus and Selective Internal Radioembolization Therapy for Unresectable Hepatic Metastases

Completed · Phase 1

Conditions studied: Neuroendocrine Tumors

In brief

The purpose of this study is to see the safety and activity of using pasireotide, everolimus and radioembolization (Selective Internal Radioembolization Therapy-SIRT) in the treatment of neuroendocrine tumors (carcinoid) that has spread to the liver. Both everolimus or radioembolization are considered "standard of care" regimens in patients with liver lesions from neuroendocrine tumors. However, the use of the combination of everolimus and radioembolization has not been formally evaluated in the setting of a clinical trial. Pasireotide is a medication that is intended to block the hormonal secretions from the neuroendocrine tumors. This study is divided into two parts. In the first part, the aim of the study is to determine the safety of combining everolimus, pasireotide, and radioembolization. For this part of the study the investigators will enroll up to 18 patients. After the investigators confirm the safety of the combination, they will conduct the second part of the study which will focus on evaluating the effectiveness of the combination. For this part of the study the investigators intend to enroll a total of 37 patients.

You may qualify if…

• Confirmed low to intermediate grade neuroendocrine tumors with unresectable liver metastasis
• Patients must have evidence of disease progression by Response Evaluation Criteria in Solid Tumors (RECIST) despite optimal octreotide therapy (octreotide long acting release [LAR] 30 mg every month)
• Prior treatment permitted include: surgery, prior systemic therapies (≤ 2 prior lines of chemotherapy), or radiation therapy
• Patients must have measurable disease by RECIST 1.1 criteria
• For the patients in the phase Ib study, neuroendocrine tumor must involve both liver lobes
• Minimum of four weeks since any major surgery, completion of radiation, or completion of all prior systemic anticancer therapy (adequately recovered from the acute toxicities of any prior therapy)
• Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
• Adequate bone marrow function as shown by:
• Absolute neutrophil count (ANC) greater than or equal to 1.5 x 10\^9/L
• Platelets greater than or equal to 100 x 10\^9/L
• Hb greater than 9 g/dL
• Adequate liver function as shown by:
• Serum bilirubin ≤ 1.5 x upper limit of normal (ULN)
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5x ULN (≤ 3x ULN in patients with liver metastases)
• International normalized ratio (INR) ≤ 1.5 (anticoagulation is allowed if target INR ≤ 1.5 on a stable dose of warfarin)
• Patient receiving low molecular weight (LMW) heparin on stable therapeutic dose for more than 2 weeks or with factor Xa level < 1.1 U/mL can be enrolled if LMW heparin can be safely discontinued at least 24 hours prior to invasive vascular procedures (angiography and SIR-sphere administration)
• Adequate renal function: serum creatinine ≤ 1.5 x ULN
• 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.
• 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.
• 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.

You may not qualify if…

• Evidence of ascites, cirrhosis, portal hypertension or portal vein thrombosis
• Prior radiation to the upper abdomen
• Contraindications to angiography
• Patients with extensive tumor replacement of the liver defined as tumor volume > 50% of liver
• Lung shunt ≥ 20%
• Prior treatment with any investigational drug within the preceding 4 weeks
• Patients receiving chronic, systemic treatment with corticosteroids or another immunosuppressive agent. Topical or inhaled corticosteroids are allowed.
• Patients should not receive immunization with attenuated live vaccines within one week of study entry or during study period. Close contact with those who have received attenuated live vaccines should be avoided during treatment with everolimus. Examples of live vaccines include intranasal influenza, measles, mumps, rubella, oral polio, bacillus Calmette-Guerin (BCG), yellow fever, varicella and TY21a typhoid vaccines.
• Uncontrolled brain or leptomeningeal metastases, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases
• Other malignancies within the past 3 years except for adequately treated carcinoma of the cervix or basal or squamous cell carcinomas of the skin
• Patients who have any severe and/or uncontrolled medical conditions or other conditions that could affect their participation in the study such as:
• Symptomatic congestive heart failure of New York Heart Association Class III or IV
• Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction within 6 months of start of study drug, serious uncontrolled cardiac arrhythmia or any other clinically significant cardiac disease
• Severely impaired lung function as defined as spirometry and diffusing capacity of lung for carbon monoxide (DLCO) that is 50% of the normal predicted value and/or 02 saturation that is 88% or less at rest on room air
• Uncontrolled diabetes as defined by hemoglobin A1C (HbA1c) > 7% despite therapy.
• Active (acute or chronic) or uncontrolled severe infections
• Liver disease such as cirrhosis or severe hepatic impairment (Child-Pugh class C)
• History of liver disease such as cirrhosis or chronic active hepatitis. Presence of Hepatitis B surface antigen (HepBSAg) or presence of hepatitis C antibody. History of, or current alcohol misuse/abuse within the past 12 months
• Patients with the presence of active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result (ELISA and Western blot)
• Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of everolimus (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection)
• Patients with an active, bleeding diathesis
• Female patients who are pregnant or breast feeding, or adults of reproductive potential who are not using effective birth control methods. Adequate contraception must be used throughout the trial and for 8 weeks after the last dose of study drug, by both sexes. (Women of childbearing potential [WOCBP] must have a negative urine or serum pregnancy test within 14 days prior to administration of pasireotide and everolimus) Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are therefore not considered effective for this study.
• Male patient whose sexual partner(s) are WOCBP who are not willing to use adequate contraception, during the study and for 8 weeks after the end of treatment
• Patients who have received prior treatment with an mammalian target of rapamycin (mTOR) inhibitor (e.g., sirolimus, temsirolimus, everolimus).
• Patients with a known hypersensitivity to everolimus or other rapamycins (e.g., sirolimus, temsirolimus) or to its excipients
