Temsirolimus and Cixutumumab in Treating Patients With Locally Advanced, Metastatic, or Recurrent Soft Tissue Sarcoma or Bone Sarcoma
This phase II trial studies how well temsirolimus and cixutumumab works in treating patients with locally advanced, metastatic, or recurrent soft tissue sarcoma or bone sarcoma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cixutumumab, can block tumor growth by blocking the ability of tumor cells to grow and spread. Giving temsirolimus with cixutumumab may be an effective treatment for soft tissue or bone sarcoma.

|Official Title:||A Phase 2 Study of Temsirolimus (CCI-779, NSC 683864) and IGF-1 Receptor Antibody Cixutumumab (IMC-A12, NSC 742460) in Patients With Metastatic Sarcomas|
- Progression-free survival rate, defined as CR + PR + SD, as assessed by RECIST criteria [ Time Frame: From study entry until recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurement recorded on study), death or date of last contact, assessed at 12 weeks ] [ Designated as safety issue: No ]
- Overall response rate (CR + PR) [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]Estimated with a confidence interval provided.
- Overall survival [ Time Frame: From entry into the study to death or the date of last contact, assessed up to 5 years ] [ Designated as safety issue: No ]Kaplan-Meier curves will be constructed for each arm.
- Change in levels of IGF-1R pathway related markers [ Time Frame: Baseline to up to 5 years ] [ Designated as safety issue: No ]Levels of the blood markers and immunohistochemistry markers will be correlated with clinical response using Fisher's exact test or Wilcoxon rank test.

Experimental: Treatment (cixutumumab and temsirolimus)
Patients receive cixutumumab IV over 60 minutes and temsirolimus IV over 30 minutes on days 1, 8, 15, 22, 29, and 36. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity.

I. To determine the proportion of patients progression-free at 12 weeks (progression free survival [PFS], defined as Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 complete response [CR] + partial response [PR] + stable disease [SD]) with (A) Insulin-like growth factor (IGF)-1receptor (R)+ soft tissue sarcomas; (B) IGF-1R+ bone tumors; or (C) IGF-1R(-) sarcomas, who are treated weekly with intravenous A12 (cixutumumab) and temsirolimus.
I. To determine the overall response rate (defined as CR + PR). II. To determine the overall survival. III. To determine the correlation of clinical outcome with pre- and post-treatment IGF-1R pathway related markers in plasma (pre and post therapy), archived tissue, and pre- and post-treatment tumor biopsies.
Patients receive cixutumumab intravenously (IV) over 60 minutes and temsirolimus IV over 30 minutes on days 1, 8, 15, 22, 29, and 36. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for at least 4 weeks.
