Neoplasm Metastasis
Conditions
Brief summary
The main purpose of this study is to evaluate the safety of different doses of olaratumab and to determine which dose should be used for future pediatric studies. The present study is open to children with advanced cancer or cancer that has spread to another part of the body. The study has three parts. In the first two parts, a specific dose of olaratumab will be given in 21 day cycles, followed by one of three standard chemotherapy regimens. In the third part, a specific dose of olaratumab will be given with one of three standard chemotherapy regimens in 21 day cycles. Participants will only enroll in one part.
Interventions
Olaratumab administered IV.
Doxorubicin administered IV.
Vincristine administered IV.
Irinotecan administered IV.
Ifosfamide administered IV.

Progression Free Survival (PFS)
Progression-free survival (PFS) is defined as the time from baseline to the first date of radiological disease progression or death due to any cause. Progressive disease (PD) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (including the baseline sum if that is the smallest). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm). The appearance of one or more new lesions is also considered progression. If participant started new treatment before PD, the participant was censored at the date of last tumor assessment prior to new therapy. If treatment was discontinued for reasons other than PD and no further assessment, censoring occurred at last tumor assessment.
Time frame: Baseline to radiological disease progression or death from any cause (Up to 2 Years)
Population: All participants who received at least one dose of study drug. Censored participants: Parts A-C include arms: Olaratumab + Vincristine + Irinotecan, Olaratumab + Ifosfamide and Olaratumab + Doxorubicin. Part A censored participants are 2, 2, and 2; Part B censored participants are 2, 2, and 1 and Part C censored participants are 2,1, and 4.
