Official Title: A Randomized Phase II Trial of Bevacizumab (Avastin) and Temsirolimus (Torisel) in Combination With Intravenous Vinorelbine and Cyclophosphamide in Patients With Recurrent/Refractory Rhabdomyosarcoma

Brief 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.

Detailed Summary:

PRIMARY OBJECTIVES:

l. To determine the feasibility of administering bevacizumab in combination with intravenous vinorelbine (vinorelbine tartrate) and cyclophosphamide (VC) in patients with recurrent rhabdomyosarcoma (RMS).

II. To determine the feasibility of administering temsirolimus in combination with VC in patients with recurrent RMS.

III. To estimate the event-free survival (EFS) of patients with recurrent/refractory RMS treated with bevacizumab and VC and compare with the EFS of those treated with temsirolimus and VC.

SECONDARY OBJECTIVES:

I. To estimate the initial (2 cycle) response rate of patients with recurrent/refractory RMS treated with bevacizumab and VC and compare with the response rate of those treated with temsirolimus and VC, and to also compare the best response rate on each regimen of protocol therapy.

II. To evaluate surrogate biological markers in patients with recurrent RMS and to estimate differences in these markers following treatment with bevacizumab and temsirolimus.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive vinorelbine tartrate intravenously (IV) over 6-10 minutes on days 1 and 8 and cyclophosphamide IV over 30-60 minutes on day 1. Patients also receive bevacizumab IV over 30-90 minutes on day 1.

ARM II: Patients receive vinorelbine tartrate and cyclophosphamide as in arm I. Patients also receive temsirolimus IV over 30-60 minutes on days 1, 8, and 15.

Current Primary Outcome:

  • Event Free Survival Probability [ Time Frame: 1 year ]
    Probability of no relapse, secondary malignancy, or death after 1 year in the study.
  • Rate of Dose-Limiting Toxicities [ Time Frame: From the date of randomization until a maximum of 12 cycles (21 days per cycle) of treatment in the absence of disease progression or unacceptable toxicities. ]
    The following events will be considered dose-limiting toxicities (DLTs): Toxicity causing delays > 14 days in delivery of a 21-day cycle of therapy; Grade ≥ 3 mucositis > 3 days duration; Grade ≥ 3 thromboembolic events; Grade ≥ 3 bleeding events; Grade ≥ 3 pulmonary events; Grade ≥ 3 hypertension; Grade 3 hyperglycemia (uncontrolled); Grade ≥ 4 hyperglycemia; Grade ≥ 4 hyperlipidemia (including cholesterol and triglycerides) that does not return to ≤ Grade 2 levels with appropriate medical management within 35 days; Grade ≥ 2 perforation including fistula or leak (gastrointestinal or any other organ); Grade ≥ 3 proteinuria; Grade ≥ 3 cardiac toxicity; Grade ≥ 3 intra-abdominal abscess/infection; Grade ≥ 3 wound complication (wound infection or dehiscence); Grade ≥ 1 Reversible Posterior Leukoencephalopathy Syndrome (RPLS); Grade ≥ 1 Microangiopathy, or Hemolytic-uremic syndrome (HUS) or Thrombotic thrombocytopenic Purpura (TTP).


Original Primary Outcome:

  • Feasibility of VC and bevacizumab
  • Feasibility of VC and temsirolimus
  • Event-free survival


Current Secondary Outcome: Response Rate (CR + PR) [ Time Frame: From the date of randomization until a maximum of 2 cycles (21 days per cycle) of treatment in the absence of disease progression or unacceptable toxicities. ]

Complete or partial anatomical response rate. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Overall Response (OR) = CR + PR.


Original Secondary Outcome: Response rate after 2 cycles
