Phase I Study of IMC-A12 (NSC# 742460) in Combination With Temsirolimus CCI-779 (NSC# 683864) in Patients With Advanced Cancers
PRIMARY OBJECTIVES:
I. To evaluate the safety and tolerability of anti-IGF-1R recombinant monoclonal antibody
IMC-A12 in combination with temsirolimus in patients with locally advanced or metastatic
cancer.
II. To determine the maximum tolerated dose of this regimen in these patients. III. To
evaluate the biologic effect of this regimen on expression/phosphorylation of potential
markers of response in patients with disease amenable to biopsy.
IV. To assess tumor metabolism as assessed by PET scan.
SECONDARY OBJECTIVE:
I. To report the clinical tumor response in patients treated with this regimen.
OUTLINE: This is a multicenter study.
Dose escalation phase: Patients receive temsirolimus IV over 30 minutes and cixutumumab IV
over 60 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of
disease progression or unacceptable toxicity. After the maximum tolerated dose (MTD) is
determined, subsequent patients are enrolled into the MTD expansion cohort.
MTD expansion cohort: Patients are assigned to 1 of 3 treatment groups.
Group A: Patients receive temsirolimus IV over 30 minutes on days 15 and 22 for course 1 and
on days 1, 8, 15, and 22 for all subsequent courses. Patients also receive cixutumumab IV
over 60 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of
disease progression or unacceptable toxicity.
Group B: Patients receive cixutumumab IV over 60 minutes on days 15 and 22 for course 1 and
on days 1, 8, 15, and 22 for all subsequent courses. Patients also receive temsirolimus IV
over 30 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of
disease progression or unacceptable toxicity.
Group C: Patients receive temsirolimus IV over 30 minutes and cixutumumab IV over 60 minutes
on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression
or unacceptable toxicity.
Patients undergo blood sample collection periodically for pharmacodynamic studies. Patients
enrolled in the MTD expansion cohort also undergo tumor biopsy and PET scans periodically.
Blood and tumor tissue samples are analyzed for molecular biomarker alterations in the
IGF-1R-mTOR signaling pathway (including, but not limited to, AKT, pAKT, IGF-1R, pIGF-1R,
IRS-1, PTEN, IRS-1, VEGFR1, VEGFR2, and CD31) by reverse phase protein arrays,
immunohistochemistry, and ELISA assays.
After completion of study treatment, patients are followed within 30 days.
