Study of RAD001 + AMG479 for Patients With Advanced Solid Tumors

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated (MTD) and recommended Phase II doses for AMG479 (ganitumab) and RAD001 (everolimus) in patients with refractory solid tumors.

II. To determine the safety and toxicity of AMG479 and RAD001.

SECONDARY OBJECTIVES:

I. To determine preliminary antitumor efficacy of AMG479 and RAD001 in solid tumors: response and stable disease rates, duration of response and of stable disease, time to progression (TTP) and overall survival (OS).

II. For all patients, to analyze tumor and blood samples for pharmacodynamic biomarkers related to IGF-1R and mTOR signaling: pAkt, pS6, p-4EBP1, PTEN, IGF-1, IGF-2, pIGF-1R and IGFBP3 and correlate with response and stable disease.

III. For all patients, to analyze the pharmacokinetic profile (PK) for RAD001 and AMG479, and correlate with response/stable disease and pharmacodynamic markers.

IV. To evaluate the effects of RAD001 on AMG 479 pharmacokinetics.

OUTLINE: This is a dose-escalation study.

Patients receive everolimus orally (PO) once daily (QD) on days 1-28 (days 1-7 and 16-28 of course 1 only) and ganitumab intravenously (IV) over 60 minutes on days 1 and 15 (day 15 of course 1 only). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at day 30, every 3 months for 2 years from registration for study treatment, every 6 months for years 3-5, and then annually thereafter.

Inclusion criteria

• Histological or cytological proof of metastatic solid tumor refractory to standard therapies, or for which no standard therapies are available.
• Patients in the expansion cohort must have a measurable site of disease according to RECIST (v 1.0)
• Laboratory values must be obtained within protocol limits and obtained within 14 days prior to registration
• Patients must have disease which is not amenable to potentially curative surgical resection of metastatic disease (curative metastasectomy).
• Must be willing to provide metastatic tissue biopsy samples (may be paraffin embedded) at baseline
• Must be willing to undergo a metastatic tissue biopsy after 2 cycles of therapy to perform pharmacodynamic research biomarkers testing.
• Subjects must be willing and able to abstain from using strong or moderate CYP3A4 inhibitors or inducers during the study period.

Exclusion criteria

• No symptomatic brain metastasis
• No prior treatment with an mTOR inhibitor or with an IGF-1R inhibitor
• No known history of diabetes mellitus
• No thrombosis or vascular ischemic events within the last twelve months
• No chronic treatment with systemic steroids or another immunosuppressive agent
• No active bleeding or a pathological condition that is associated with a high risk of bleeding
• No known history of HIV seropositivity
• No known history of Hepatitis B or Hepatitis C seropositivity
• No known hypersensitivity to AMG 479, RAD001 (everolimus), other rapamycins (sirolimus, temsirolimus), or to its excipients
• No planned immunization with attenuated live viruses during the study period
