About

The purpose of this research study is to determine the safety of the combination of SOM230 and RAD001, as well as determine the highest dose of this combination that can be given to people safely. SOM230 is an investigational drug that is similar to Sandostatin LAR. Sandostatin is an approved drug for the use of treating symptoms of neuroendocrine tumors. SOM230 has shown to be effective in patients who have become resistant to Sandostatin and may also stop cancer cells from growing. RAD001 is an investigational drug that also may stop cancer cells from growing.

Full description

• Participants will be receiving two study medications, SOM230 and RAD001, during each treatment cycle. Each treatment cycle lasts 4 weeks.
• For the first four weeks of treatment, the participant will self-administer the SOM230 twice a day by subcutaneous injection. If they tolerate the SOM230 after 4 weeks, they will switched to the long-acting SOM230 which will be administered during scheduled treatment visits once every 4 weeks. For the first two weeks after switching to the long-acting SOM230, participants will continue to self-administer the short-acting SOM230 twice a day.
• RAD001 will be taken orally once every day.
• On Day 1 of every cycle, a physical exam and blood tests will be performed. Following every 2 cycles of treatment an assessment of the tumor by CT scan wil be performed.
• Pharmacokinetic (pK) blood samples will be taken on days 1 and 15 of cycle one. The pK samples will be taken right before the study drug is administered and then 1, 2, 3, and 5 hours later.

• Negative serum pregnancy test for women of childbearing potential.
• Fasting serum cholesterol less than or equal to 300mg/dL or less than or equal to 7.75mml/L AND fasting triglycerides of less than or equal to 2.5 x ULN.

Exclusion criteria

• Chronic treatment with systemic steroids or another immunosuppressive agent.
• Immunization with attenuated live vaccines during study or within 1 week of study entry.
• Uncontrolled brain or leptomeningeal metastases, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases.
• Prior or concurrent malignancy, except for the following: adequately treated basal cell or squamous cell skin cancer, or other adequately treated in situ cancer, or any other cancer from which the patient has been disease free for five years.
• Uncontrolled diabetes mellitus or a fasting plasma glucose of > 1.5 ULN.
• Symptomatic cholelithiasis
• Congestive heart failure, 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.
• Presence of active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result.
• Any severe and/or uncontrolled medical condition or other conditions that could affect their participation in the study such as: severely impaired lung function; active or uncontrolled infection/disorders; nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by treatment with the study therapy; impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of RAD001; history of alcohol or drug abuse in the 6 month period prior to receiving treatment.
• Known hypersensitivity to RAD001 or other rapamycins or its excipients.
• Known hypersensitivity to somatostatin analogues or any component of the pasireotide or octreotide LAR or s.c. formulations.

Pasireotide and RAD001

Experimental group

Description:

RAD001 was administered orally as a once-daily dose. Pasireotide s.c. was self-administered s.c. twice daily for 4 weeks. If pasireotide s.c. was tolerated, patients received pasireotide LAR i.m. at the corresponding dose level. Pasireotide s.c. was continued for an additional 2 weeks after administration of pasireotide LAR until anticipated steady-state levels of pasireotide LAR were achieved. Pasireotide LAR was administered every 28 days. Cycles for everolimus and pasireotide LAR were repeated every 28 days.

Drug: SOM230
