Summary

This randomized phase II trial studies how well vinorelbine tartrate and cyclophosphamide work in combination with bevacizumab or temsirolimus in treating patients with recurrent or refractory rhabdomyosarcoma. Drugs used in chemotherapy, such as vinorelbine tartrate and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, 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. Bevacizumab may also stop the growth of rhabdomyosarcoma by blocking blood flow to the tumor. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether combination chemotherapy is more effective when given together with bevacizumab or temsirolimus in treating rhabdomyosarcoma.

Eligibility Criteria

Inclusion Criteria

  • Diagnosis
  • Patients with first relapse or progression of rhabdomyosarcoma are eligible
  • Patients with primary refractory disease are eligible
  • Primary refractory disease is defined as first progression after receiving at least one course of cyclophosphamide or ifosfamide containing chemotherapy without prior demonstration of a radiographic response to chemotherapy (progression on irinotecan-containing chemotherapy without cyclophosphamide or ifosfamide containing chemotherapy will not be considered a first progression)
  • Note: Patients without measurable or evaluable disease are eligible
  • Patients must have had a previous histological verification of rhabdomyosarcoma at original diagnosis
  • Patients must have a Karnofsky or Lansky performance status score of >= 50%, corresponding to Eastern Cooperative Oncology Group (ECOG) categories of 0, 1, or 2; use Karnofsky for patients > 16 years of age and Lansky for patients = = 8 weeks
  • Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study
  • Myelosuppressive chemotherapy: Must not have received within 3 weeks prior to entry onto this study (4 weeks if prior nitrosourea)
  • Biologic (anti-neoplastic agent):
  • Patients may have received prior therapy with oral tyrosine kinase inhibitors or other similar agents; at least 7 days must have elapsed since the completion of therapy with a biologic agent and all toxicities must have resolved to = 3 months must have elapsed; for allogeneic SCT, >= 6 months must have elapsed and no evidence of active graft vs. host disease
  • Patients must have recovered from any surgical procedure before enrolling on this study
  • Minor surgical procedures (e.g., biopsies involving core or fine-needle aspiration procedures, infusaport or Broviac line placement, paracentesis, or thoracocentesis) need to have fully healed and occurred > 7 days prior to enrollment
  • Patients who have had a major surgical procedure (such as laparotomy, thoracotomy, open biopsy, or resection of tumor) can only be enrolled on study > 28 days from such procedure
  • Peripheral absolute neutrophil count (ANC) >= 750/μL
  • Platelet count >= 75, 000/μL (transfusion independent, defined as without transfusion for >= 1 week prior to enrollment)
  • Hemoglobin >= 8.0 g/dL (may receive packed red blood cells [PRBC] transfusions)
  • Bone marrow disease involvement of tumor is allowed, however, peripheral blood count criteria must still be met
  • Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 OR a serum creatinine based on age/gender as follows:
  • = = 13 years)
  • = = 16 years)
  • Urine protein level:
  • Patients aged = 17 years: Urine protein should be screened by urine analysis; if protein is 2+ or higher, 24-hour urine protein must be obtained and the level must be = 27% by echocardiogram or ejection fraction of >= 50% by radionuclide angiogram

Exclusion Criteria

  • Patients with botryoid histology, any stage or group, are ineligible
  • Patients with embryonal histology, stage I or clinical group 1 at initial disease presentation, who present with local or regional recurrence, are ineligible
  • Patients who previously received craniospinal irradiation are ineligible
  • Patients who previously received vinorelbine, bevacizumab, temsirolimus, or any other direct vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR-) or mammalian target of rapamycin (mTOR-) targeting agents are ineligible
  • Patients with known central nervous system (CNS) disease (excluding intracranial/intraspinal extension secondary to local progression of a parameningeal or paraspinal primary), except for those with treated brain metastasis, are ineligible
  • Treated brain metastases are defined as having no ongoing requirement for steroids and no evidence of progression or hemorrhage after treatment for at least 3 months, as
