About

This phase II trial studies how well cixutumumab and temsirolimus work in treating patients with recurrent or refractory sarcoma. 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. Giving cixutumumab and temsirolimus together may kill more tumor cells.

Full description

PRIMARY OBJECTIVES:

I. To determine the objective response rate to the combination of cixutumumab and temsirolimus in patients with relapsed or refractory osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, or non-rhabdomyosarcoma soft tissue sarcoma.

II. To further describe the toxicities (including dose-limiting toxicities) of cixutumumab and temsirolimus administered on this schedule.

SECONDARY OBJECTIVES:

I. To assess the progression-free survival for patients treated in each disease stratum with this drug combination.

II. To assess the incidence of insulin-like growth factor 1 receptor (IGF-1R), insulin receptor, ERK, RON, and mammalian target of rapamycin (mTOR) pathway activation in archival tumor material, and correlate with response.

III. To evaluate minimal residual disease and IGF-1R tumor cell expression in the blood and bone marrow of Ewing sarcoma patients using flow cytometry.

OUTLINE: This is a multicenter study. Patients are stratified according to diagnosis (osteosarcoma vs Ewing sarcoma/PNET vs rhabdomyosarcoma vs non-rhabdomyosarcoma soft tissue sarcoma).

Patients receive cixutumumab IV over 1 hour 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.

Archived tumor tissue samples from most recent biopsy are collected and analyzed for IGF-1R, insulin receptor, AKT, ERK, mTOR, and S6 kinase pathway activation by immunohistochemistry (IHC) and banked for future correlative studies. Blood and bone marrow samples, from patients with Ewing sarcoma, may be collected at baseline and periodically during treatment for minimal residual disease analysis by flow cytometry.

After completion of study treatment, patients are followed up periodically for 5 years.

Inclusion and exclusion criteria

Inclusion Criteria:

Patients with any of the following tumors who have experienced relapse following front-line therapy, or who are refractory to front-line therapy, are eligible:
- Osteosarcoma
- Ewing sarcoma/peripheral primitive neuroectodermal tumor (PNET)

All patients are required to submit archival tumor samples for immunohistochemical analysis (either paraffin-embedded tumor blocks or unstained slides)
- Tissue samples collected at original diagnosis or at relapse or at any subsequent resections or biopsies should be available and ready for shipment to the Biopathology Center (BPC) at time of study enrollment; the samples are required even if tissue samples have previously been sent to the BPC for other purposes or studies; blocks or slides should be shipped to the BPC within 7 days of study enrollment
Patients must have radiographically measurable disease
- Measurable disease is defined as the presence of at least one lesion on magnetic resonance imaging (MRI) or computed tomography (CT) scan that can be accurately measured with the longest diameter a minimum of 10 mm in at least one dimension (CT scan slice thickness no greater than 5 mm)
- The following do not qualify as measurable disease:
  - Malignant fluid collections (e.g., ascites, pleural effusions)
  - Bone marrow infiltration
  - Lesions only detected by nuclear medicine studies (e.g., bone, gallium, or positron emission tomography [PET] scans)
  - Elevated tumor markers in plasma or cerebrospinal fluid(CSF)
  - Previously radiated lesions that have not demonstrated clear progression post radiation
  - Leptomeningeal lesions that do not meet the measurements noted above
Patient?s current disease state must be one for which there is no known curative therapy or therapy proven to prolong survival with an acceptable quality of life
Patients with known central nervous system metastases are excluded unless treated surgically or with radiotherapy and stable with no recurrent lesions for at least 3 months
Patients must have a Lansky or Karnofsky performance status score of ? 50%, corresponding to Eastern Cooperative Oncology Group (ECOG) categories 0, 1, or 2; use Karnofsky for patients > 16 years of age and Lansky for patients ? 16 years of age
- Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
For patients with solid tumors without bone marrow involvement:
- Peripheral absolute neutrophil count (ANC) ? 1,000/?L
- Platelet count ? 100,000/?L (transfusion independent, defined as not receiving platelet transfusions within a 7-day period prior to enrollment)
- Hemoglobin ? 8.0 g/dL (may receive red blood cell [RBC] transfusions)
For patients with solid tumors and known bone marrow metastatic disease:
- ANC ? 750/?L
- Platelet count ? 50,000/?L (may receive platelet transfusions)
- Hemoglobin ? 8.0 g/dL (may receive RBC transfusions)
  - For patients with known bone marrow metastatic disease, transfusions are permitted to meet both platelet and hemoglobin criteria; patients must not be known to be refractory to red blood cell or platelet transfusions
Creatinine clearance or radioisotope GFR ? 70 mL/min OR a serum creatinine based on age/gender as follows:
- 0.6 mg/dL (1 to < 2 years of age)
- 0.8 mg/dL (2 to < 6 years of age)
