- Time to adverse analytic event (event-free survival [EFS]) [ Time Frame: From the time of randomization, assessed up to 10 years ]Will be defined to be disease-related event, diagnosis of a second malignant neoplasm, or death. The two regimens will be compared using the relative risk regression model with strata representing those used for randomization. A log-partial-likelihood one-sided test of size 0.025 will be used to compare the two regimens. A parametric model that treats disease progressions identified at routine visits as interval censored observations with the left censoring time as the date of the last screening prior to the identification of the relapse and other relapse times as being known exactly will be fit.
- Overall Survival [ Time Frame: From enrollment to death regardless of cause or last patient contact, assessed up to 10 years ]
- Overall toxicity of the addition of ganitumab to vincristine sulfate, doxorubicin hydrochloride and cyclophosphamide (VDC)/ifosfamide and etoposide (IE) [ Time Frame: Up to 30 days after last dose of study drug ]Will be defined using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. The 95% confidence interval for the toxicity-event rate for each phase noted above for patients enrolled on the comparator therapy will be constructed.
- Sinusoidal obstructive disease (SOS) associated with the addition of ganitumab to VDC/IE [ Time Frame: Up to 30 days after last dose of study drug ]A phase where a patient experiences any SOS will be considered a phase with an SOS toxicity-event. The effect of possible correlations between analytic units that arises because some analytic units are contributed by the same individual will be explored. A random effects binomial model where a Normally distributed random effect with 0 mean and unknown variance chi-squared is contributed by each unit in a pair of analytic units that arise from the same individual will be explored.
- Risk of death [ Time Frame: Up to 10 years ]The relative risk for death and the naive p-value associated with the null hypothesis H0: relative risk for death is 1 will be estimated using the stratified partial likelihood for the relative risk regression model accounting for the factors used to stratify randomization at the time full information is obtained for the EFS comparison.
- Bone marrow response rates [ Time Frame: Up to 10 years ]Each bone marrow evaluable patient will be assessed for the presence or absence of bone marrow metastatic disease over the interval between enrollment and the time of first local control measure or the end of the Induction reporting period, whichever comes first. Only one evaluation of best response will be used to classify the patient as complete responder (no evidence of marrow disease) or incomplete responder (residual marrow disease or progression). An estimate of the proportion of patients who achieve complete bone marrow response and an associated 95% confidence interval provided.
- Tolerability of maintenance ganitumab [ Time Frame: Up to 10 years ]At the time each study progress report is prepared, the toxicity-event rate will be calculated and the one-sided test of size 0.05 of the null hypothesis that the toxicity-event rate is 25% will be performed.
- Ganitumab pharmacokinetics (PK) [ Time Frame: Prior to the first dose of ganitumab, prior to the second dose of ganitumab on Induction day 15, prior to the third dose of ganitumab on Induction day 29, prior to the sixth dose of ganitumab on Induction day 71 (Induction) ]Results of this PK testing will be reported descriptively, with an emphasis on the proportion of patients achieving a trough serum ganitumab concentration >= 10 ug/mL at a dose of 18 mg/kg IV every 3 weeks. Additional trough levels in Maintenance will allow for estimation of accumulation, half-life, and steady state clearance of ganitumab.
- Feasibility of stereotactic body radiotherapy (SBRT) [ Time Frame: Up to 10 years ]Defined as an individual that has SBRT planned for at least one site, starts the treatment of metastatic disease phase of the protocol and has at least 85% of tumor sites planned to be treated with SBRT receive successful SBRT. Successful treatment delivery is defined as a treatment plan that is acceptable or has only minor variation as assessed by Imaging and Radiation Oncology Core Rhode Island (formerly Quality Assurance Review Center). In addition to this feasibility assessment, efficacy will be evaluated by comparing the failure rate at irradiated bone metastases with SBRT and external beam radiation therapy (EBRT), recognizing selection bias between patients treated with SBRT or EBRT.
- Serum IGF pathway component and tissue protein, deoxyribonucleic acid (DNA), and ribonucleic acid markers [ Time Frame: Up to 10 years ]In addition to the log rank test the modeling approach will be used for the primary study comparison. Linear trend in EFS-risk will be investigated by segregating the marker level according to quartiles. For bone marrow response rate analyses, Fisher's exact test will be used to compare the objective bone marrow response rate (complete response vs. incomplete response) at start of local control between patients with biomarker levels above and below the group median.
- Tumor cell surface IGF-1R expression [ Time Frame: Up to 10 years ]The percentage of patients with detectable bone marrow micrometastatic disease at baseline who clear their bone marrow micrometastatic disease after three and six cycles of study therapy will be reported descriptively according to treatment arm. Extent of tumor cell IGF-1R co-expression will also be reported. Moreover, the change in tumor cell IGF-1R co-expression in patients treated with and without ganitumab will be reported descriptively.
- Germline polymorphisms in EGFR [ Time Frame: Up to 10 years ]EFS will be compared between patients with and without the presence of the minor allele using the log rank test, both for the entire patient population and for patients randomized to ganitumab. In addition to the log rank test, will use the modeling approach described above for the primary study comparison. Additional analyses will compare overall survival and objective bone marrow response rate prior to local control as clinical outcomes of interest. In addition, an association between the number of copies of the minor allele and these clinical endpoints will be evaluated.
- EWS translocation [ Time Frame: Up to 10 years ]The institutional result of EWS tumor testing will be categorized as translocation detected (yes v. no) and the type of translocation detected will also be recorded. The proportion of patients with a particular EWS translocation variant will be tabulated. Risk for EFS-event will be compared across groups defined by translocation positivity using the log rank test.
- Circulating tumor DNA (ctDNA) testing [ Time Frame: Up to 10 years ]Will report the proportion of patients that have a change in translocation result associated with ctDNA testing across time periods.
- Serial genomic profiling [ Time Frame: Up to 10 years ]Will be identified by flow cytometry. Profiles will be presented graphically, and samples obtained from different sites of tumor within the same individual will also be presented.

Ages Eligible for Study: | up to 50 Years (Child, Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients with histologic diagnosis (by institutional pathologist) of newly diagnosed Ewing sarcoma or peripheral primitive neuroectodermal tumor (PNET) arising from bone or soft tissue and with metastatic disease involving lung, bone, bone marrow, or other metastatic site
-
For the purpose of this study metastatic disease is defined as one or more of the following:
- Lesions which are discontinuous from the primary tumor, are not regional lymph nodes, and do not share a bone or body cavity with the primary tumor; skip lesions in the same bone as the primary tumor do not constitute metastatic disease; skip lesions in an adjacent bone are considered bone metastases; if there is any doubt whether lesions are metastatic, a biopsy of those lesions should be performed
- Contralateral pleural effusion and/or contralateral pleural nodules
- Distant lymph node involvement
-
Patients with pulmonary nodules are considered to have metastatic disease if the patient has:
- Solitary nodule >= 0.5 cm or multiple nodules of >= 0.3 cm unless lesion is biopsied and negative for tumor
- Patients with solitary nodule < 0.5 cm or multiple nodules < 0.3 cm are not considered to have lung metastasis unless biopsy documents tumor
-
Bone marrow metastatic disease is based on morphologic evidence of Ewing sarcoma based on hematoxylin and eosin (H&E) stains; in the absence of morphologic evidence of marrow involvement on H&E, patients with bone marrow involvement detected ONLY by flow cytometry, reverse-transcriptase (RT)-polymerase chain reaction (PCR), fluorescence in situ hybridization (FISH), or immunohistochemistry will NOT be considered to have clinical bone marrow involvement for the purposes of this study
- This study requires bilateral bone marrow biopsies at study entry; the suggested approach for patients with large pelvic tumors in which a posterior iliac crest bone marrow biopsy would track through the tumor is to instead undergo 2 marrow biopsies on the contralateral side (either 2 posterior biopsies or one posterior and one anterior biopsy)
- Bone metastasis: This study utilizes whole body FDG-PET scans to screen patients for bone metastases; areas suspicious for bone metastasis based on FDG-PET scans require confirmatory anatomic imaging with either MRI or computed tomography (CT) (whole body FDG-PET/CT or FDG-PET/magnetic resonance [MR] scan acceptable); whole body technetium bone scans may be performed at the discretion of the investigator and are not required; for patients without other sites of metastatic disease whose sole metastatic site to qualify for study entry is a single area suspicious for bone metastasis identified by FDG-PET, confirmatory biopsy or anatomic imaging evidence of an associated soft tissue mass at that site is required for study entry
- Patients must have adequate tumor tissue to meet the minimum requirement for submission
- Enrolling institutions are reminded that submission of pre-treatment serum, tumor tissue and whole blood is required
- Patients should only have had a biopsy of the primary tumor without an attempt at complete or partial resection; patients will still be eligible if excision was attempted or accomplished as long as adequate anatomic imaging (MRI for most primary tumor sites) was obtained prior to surgery
-
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 (performed within 7 days prior to enrollment):
- Age < 6 months: Maximum serum creatinine (mg/dL): 0.4 for males and females
- Age 6 months to < 1 year: Maximum serum creatinine (mg/dL): 0.5 for males and females
- Age 1 to < 2 years: Maximum serum creatinine (mg/dL): 0.6 for males and females
- Age 2 to < 6 years: Maximum serum creatinine (mg/dL): 0.8 for males and females
- Age 6 to < 10 years: Maximum serum creatinine (mg/dL): 1 for males and females
- Age 10 to < 13 years: Maximum serum creatinine (mg/dL): 1.2 for males and females
- Age 13 to < 16 years: Maximum serum creatinine (mg/dL): 1.5 for males and 1.4 for females
- Age >= 16 years: Maximum serum creatinine (mg/dL): 1.7 for males and 1.4 for females
- Total bilirubin =< 1.5 x upper limit of normal (ULN) for age (performed within 7 days prior to enrollment), and
- Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) < 3 x upper limit of normal (ULN) for age (performed within 7 days prior to enrollment) (except for patients with liver metastasis who may enroll if ALT < 5 times ULN for age)
- Shortening fraction of >= 27% or
- Ejection fraction of >= 50%
- Patients must have a normal blood sugar level for age to participate; if an initial random draw (ie. non-fasting) blood glucose value is out of range, it is acceptable to repeat this test as a fasting draw
- All patients and/or their parents or legal guardians must sign a written informed consent
- All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met
Exclusion Criteria:
- Patients with regional node involvement as their only site of disease beyond the primary tumor will not be eligible
- Patients whose primary tumors arise in the intra-dural soft tissue (e.g. brain and spinal cord) are not eligible
- Patients who have received prior chemotherapy or radiation therapy are not eligible
- Female patients of childbearing potential are not eligible unless a negative pregnancy test result has been obtained; lactating females are not eligible unless they have agreed not to breastfeed their infants for the duration of protocol therapy; sexually active patients of reproductive potential are not eligible unless they have agreed to use an effective contraceptive method for the duration of protocol therapy
- Patients with known pre-existing diabetes mellitus will be excluded from study
- Patients receiving chronic pharmacologic doses of corticosteroids are not eligible; for the purposes of eligibility, chronic exposure is defined as anticipated exposure of > 3 weeks, including the sum of both pre-enrollment and anticipated post-enrollment dosing; patients on acute corticosteroid therapy (=< 3 weeks of total planned exposure) must still meet the normal blood glucose requirement; patients receiving chronic inhaled corticosteroids or chronic physiologic replacement doses of corticosteroids are eligible
