Summary

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.

Eligibility Criteria

Inclusion Criteria

  • Patients must have histologically or cytologically confirmed sarcoma of soft tissue or bone; all patients will have IGF-1R testing at Memorial Sloan-Kettering Cancer Center (MSKCC) by immunohistochemistry (IHC); patients with confirmation of IGF-1R status in pre-existing tumor specimens will be enrolled on one of three arms of the study:
  • Arm A: IHC IGF-1R (+) sarcomas of soft tissue
  • Arm B: IHC IGF-1R (+) sarcomas of bone
  • Arm C: Any IGF-1R (-) sarcomas
  • Subjects must have metastatic and/or locally advanced or locally recurrent disease
  • Patients treated at Memorial Sloan Kettering Cancer Center must consent to tumor biopsies before therapy and after the 2nd week of therapy; subjects who do not have accessible tumor for biopsy may be enrolled at the discretion of the Principal Investigator
  • Patients must have measurable disease by RECIST 1.1; measurable disease (a 'target' lesion) is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded); each lesion must be >= 10 mm when measured by computed tomography (CT) (CT scan slice thickness no greater than 5 mm); >= 10 mm caliper measurement by clinical exam (lesions which cannot be accurately measured with calipers should be recorded as non-measurable); and >= 20 mm by chest x-ray
  • A minimum of 1 and a maximum of 4 prior systemic therapy regimens for recurrent/metastatic disease; the last dose of systemic therapy (include tyrosine kinase inhibitors) must have been given at least 4 weeks prior to initiation of therapy; patients receiving carmustine (BCNU) or mitomycin C must have received their last dose of such therapy at least 6 weeks prior to initiation of therapy
  • Patients with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months following the procedure with no neurological signs or symptoms and no requirement for systemic glucocorticoids are eligible for study
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
  • Absolute neutrophil count >= 1.5 x 10^9/l; patients with neutropenia on a familial basis may still be enrolled on study; please contact the Principal Investigator (PI) who will discuss the patient with Cancer Therapy Evaluation Program (CTEP)
  • Platelets >= 100 x 10^9/l
  • Total bilirubin = 1-1.5 X ULN, the starting dose of temsirolimus is 15 mg/week
  • Albumin >= 3 g/dL
  • Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT)/serum glutamate pyruvate transaminase (SGPT) = 1.0- 3.0 X ULN, the starting dose of temsirolimus is 15 mg/week
  • Serum creatinine = = 4 weeks beyond treatment of any systemic therapy, other investigational therapy, biological, targeted agents or radiotherapy, and must have recovered to =< Grade 1 toxicity or previous baseline for each toxicity; specifically excluded are the laboratory examinations serum lipase or amylase (without overt pancreatitis), hypophosphatemia, hypomagnesemia, and lymphopenia; patients may have received palliative low dose radiotherapy to the limbs 1-4 weeks before this therapy provided pelvis, sternum, scapulae, vertebrae, or skull were not included in the radiotherapy field
  • Patients may not have received prior IGFR1 inhibitors
  • Patients may not have received prior mammalian target of rapamycin (mTOR) inhibitors (such as sirolimus, everolimus, ridaforolimus, or temsirolimus)
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to temsirolimus, A12, or other agents used in the study
  • Patients with hyperglycemia, defined as fasting serum glucose above 120 mg/dl, or those patients already on oral anti-diabetic or insulin therapy
  • Uncontrolled intercurrent illness including, but not limited to, known ongoing or active infection, including human immunodeficiency virus (HIV), active hepatitis B or C, symptomatic congestive heart failure, unst
