This phase I trial is studying the side effects and best dose of cixutumumab when given together with temsirolimus in treating younger patients with solid tumors that have recurred or not responded to treatment. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Outcome Measures:
  • Maximum-tolerated dose and recommended phase II dose based on the incidence of dose-limiting toxicity (DLT) as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: 28 days ]
  • Toxicities as assessed by the NCI CTCAE version 4.0 [ Time Frame: Up to 30 days after the last dose of treatment ]
  • Pharmacokinetics (PK) of cixutumumab [ Time Frame: At end of infusion, at 1, 3, 6, and 24 hours, days 1, 4, 8, 15, 22, and 28 (of course 1), and days 15 and 28 (of course 2) ]
    The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).

  • Pharmacokinetics of temsirolimus [ Time Frame: At end of infusion, at 15 and 30 minutes, at 1, 3, 6, and 24 hours, days 1, 4, 7, and 28 (of course 1), and days 15 and 28 (course 2) ]
    The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).

Secondary Outcome Measures:
  • Disease response according to Response Evaluation Criteria in Solid Tumors (RECIST) [ Time Frame: Up to 4 years ]
    Reported descriptively.

  • Change IGFR and insulin receptor expression [ Time Frame: From baseline to up to 28 days (of course 1) ]
    Summary statistics and descriptive plots will be generated for IGFR expression. The changes will be assessed using paired t-test or Wilcoxon matched pairs signed rank sum test when appropriate.

  • Change in levels of S6K1, AKT, eIF4G, and associated phosphoproteins [ Time Frame: From baseline to up to 28 days (of course 1) ]
    Summary statistics and descriptive plots will be generated. The changes will be assessed using paired t-test or Wilcoxon matched pairs signed rank sum test when appropriate.

Detailed Description:


I. To estimate the maximum tolerated dose (MTD) and recommended Phase II dose of IMC-A12 (anti-insulin growth factor-1 receptor monoclonal antibody) (cixutumumab) administered as an intravenous infusion once weekly in combination with CCI-779 (temsirolimus) administered intravenously once weekly to children with refractory solid tumors.

II. To define and describe the toxicities of IMC-A12 in combination with temsirolimus administered on this schedule.

III. To characterize the pharmacokinetics of IMC-A12 in combination with temsirolimus in children with refractory cancer.


I. To preliminarily define the antitumor activity of the combination of IMC-A12 and temsirolimus within the confines of a Phase I study.

II. To assess the biologic activity of IMC-A12 by assessing: changes in insulin-like growth factor receptor (IGFR) expression and phosphorylation and insulin-receptor expression and phosphorylation in peripheral blood mononuclear cells (PBMNC).

III. To assess the biological activity of temsirolimus by measuring levels of phosphorylated (phosphor)-ribosomal protein S6 kinase, 70kDa, polypeptide 1 (S6K1), phosphor-protein kinase B (AKT), phosphor-eukaryotic translation initiation factor 4 gamma, 1 (eIF4G) in PBMNC.

IV. To assess the incidence of IGFR expression as well as mechanistic target of rapamycin (mTOR) pathway activation in recurrent or refractory solid tumors of childhood.


Patients receive cixutumumab intravenously (IV) over 60 minutes and temsirolimus IV over 30 minutes on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 25 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up periodically.
