Cyclophosphamide, Topotecan Hydrochloride, and Bevacizumab in Treating Patients with Relapsed or Refractory Ewing Sarcoma or Neuroblastoma
This trial is active, not recruiting.
|Treatment||cyclophosphamide, topotecan, and bevacizumab|
|Sponsor||Memorial Sloan Kettering Cancer Center|
|Start date||December 2011|
|End date||December 2017|
|Trial size||9 participants|
|Trial identifier||NCT01492673, 11-183|
The purpose of this study is to find out what effects, good and/or bad treatment with a new combination of drugs, cyclophosphamide, topotecan, and bevacizumab has on the patient and their cancer.
The medications, cyclophosphamide and topotecan, are standard drugs often used together for the treatment of cancer in children with either Ewing's sarcoma or neuroblastoma.
Bevacizumab is an experimental drug called an antibody that targets a protein important in the growth of cancer cells called vascular endothelial growth factor (VEGF). VEGF is made by tumor and other surrounding cells to help make blood vessels needed for the growth and spread of cancer cells in the body. The way that bevacizumab works is to stop the cancer cells from making their own blood supply, causing the tumor to stop growing bigger or from spreading. In adult clinical trials, bevacizumab has shown promising anti-cancer activity in patients with cancer of the colon/rectum (colorectal) and breast. It has been approved by the Food and Drug Administration (FDA) for use in patients with colorectal cancer but not in cancers found in children. Bevacizumab has been tested in early clinical studies in children and has been shown to be safe.
Other goals of this study will include research tests designed to test the following changes in the patient or their cancer: to see how the body handles and breaks down bevacizumab (pharmacokinetics), to look at changes in proteins in the blood that may affect the way the cancer responds to the combination (angiogenic profile, angiogenesis associated serum biomarkers), to look at changes in genes that may affect how the cancer responds to treatment with this combination of medications (metabolic signature), and to monitor the effects of changes in the way the body grows and develops before and after bevacizumab is given.

time frame: 2 years
time frame: 2 years
Male or female participants up to 21 years old.
- Patients must have histologically confirmed relapsed/refractory Ewing's sarcoma or neuroblastoma.
- Patients must have measurable disease. Patients with a diagnosis of neuroblastoma with MIBG avid disease only are permitted to enroll on this study.
- Patients must be ≤ 21 years of age at time of diagnosis

- Written informed consent
- Organ and marrow function defined as follows: Hematologic function, as follows
- Absolute neutrophil count ≥ 1000/μL
- Platelets ≥ 100 x 109/L (without transfusion < 14 days before enrollment) Hemoglobin ≥ 9 gm/dl Renal function, as follows:
- Serum creatinine ≤ ULN for age. Refer to Appendix H for normal values for serum creatinine in children.
- If serum creatinine above these values, the calculated creatinine clearance or radioisotope GFR must be ≥ 60 ml/min/1.73 m2
- Urinary protein < 2+ (unless total quantitative protein is < 500 mg protein/day as determined by 24 H urine collection) for pediatric patients please refer to the CTCAE V4.0 for values. Hepatic function, as follows:
- Total bilirubin ≤ 1.5x ULN
- AST and ALT ≤ 2.5x ULN for institution or ≤ 5x ULN for institution if clearly attributable to liver metastases
- Albumin ≥ 2.5 g/dl. Coagulation: INR ≤ 1.5x ULN.
- Prior Treatment: Patients must have recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiation therapy prior to entry on study. Patients must have had at least one prior treatment regimen. Patients may have received treatment previously with cyclophosphamide or topotecan but no prior bevacizumab.
- Myelosuppressive chemotherapy: Two weeks must have elapsed since administration of previous chemotherapy.
- Biologic agents: At least 2 weeks must have elapsed since the completion of therapy with a monoclonal antibody. Seven days must have elapsed since the last dose of retinoids
- Radiation therapy: For all patients, ≥ 4 weeks must have elapsed for local XRT; ≥ 6 months must have elapsed if prior radiation to ≥ 50% of the pelvis or if substantial bone marrow irradiation. Patients with a history of prior radiation with field including the heart (e.g. mantle) will be excluded.
- Stem cell transplant: Patients who have undergone prior stem cell transplantation will not be excluded from study entry. At least 3 months must have elapsed since autologous or allogeneic stem cell transplantation. Patients must have no evidence of active graft versus host disease.
- Patients with centrally-located pulmonary or mediastinal primary tumors or metastases adjacent to or invading large blood vessels.
- Prior left chest wall irradiation or a cumulative anthracycline dose of greater or equal to 300 mg/m2, unless the ejection fraction or fraction shortening is within normal institutional limits, in which case the patient can be enrolled.
- Inability to comply with study and/or follow-up procedures
- Life expectancy of less than 3 months
- Current, recent (within 4 weeks of the first infusion of this study), or planned participation in an experimental drug study other than a Genentech-sponsored bevacizumab cancer study
- Active second malignancy, other than superficial basal cell and superficial squamous (skin) cell, or carcinoma in situ of the cervix within last five years
- History of other malignancies, except for other solid tumors curatively treated with no evidence of disease for > 3 years prior to enrollment.
- Known infection with human immunodeficiency virus (HIV).
- Uncontrolled hypertension (sBP >150 mmHg and/or diastolic BP > 100 mmHg, found on two consecutive measurements separated by a one week period of time despite adequate medical support).

- Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, LINAC, or equivalent) or a combination as deemed appropriate by the treating physician.

(Minor surgical procedures include minimally invasive procedures such as fine needle aspiration, core biopsy, etc requiring little if any supportive care excluding lumbar puncture and bone marrow aspiration/biopsy.)
