Cixutumumab and Temsirolimus in Treating Younger Patients With Recurrent or Refractory Sarcoma

• Status: Completed
• Trial end date: 2014-04-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• 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)

• 1.0 mg/dL (6 to < 10 years of age)

• 1.2 mg/dL (10 to < 13 years of age)

• 1.5 mg/dL (males) or 1.4 mg/dL (females) (13 to < 16 years of age)

• 1.7 mg/dL (males) or 1.4 mg/dL (females) ( ? 16 years of age)

• Total bilirubin ? 1.5 times upper limit of normal (ULN)

• Serum glutamic pyruvate transaminase(SGPT) (alanine aminotransaminase [ALT]) ? 2.5 times ULN (for the purpose of this study, the ULN for SGPT is 45 U/L)

• Serum albumin ? 2 g/dL

• Patients with seizure disorder may be enrolled if receiving non-enzyme-inducing anticonvulsants and well controlled

• Patients with known type I or type II diabetes mellitus are not eligible

• Serum glucose values must be within the normal limits for age; if the initial blood glucose is a random sample that is outside normal limits, then a follow-up fasting blood glucose should be obtained and must be within the normal limits for age

• Serum cholesterol levels must be < grade 2 (< 300 mg/dL), and serum triglyceride levels must be < grade 2 (< 2.5 times ULN)

• Patients who are pregnant or breast-feeding are not eligible for this study

• Negative pregnancy tests must be obtained in girls who are post-menarchal

• Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method for the duration of the study and for 3 months after the last dose of cixutumumab

• Patients who have an uncontrolled infection are not eligible

• Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study are not eligible

• See Disease Characteristics

• There is no limit to the number of prior treatment regimens; however, patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to study enrollment

• At least 7 days must have elapsed since the completion of therapy with a growth factor; at least 14 days must have elapsed after receiving pegfilgrastim

• At least 7 days must have elapsed since the completion of therapy with a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period prior to enrollment must be extended beyond the time during which adverse events are known to occur
