Brief summary
Participants in this single-center, open-label, dose-escalation, Phase 1 study will initially receive intravenous (IV) olaratumab once every 2 weeks or on Days 1 and 8 every 3 weeks for 6 weeks (one cycle). After the first cycle, participants experiencing an overall response of complete response (CR), partial response (PR), or stable disease (SD) will continue to receive olaratumab at their cohort dose and schedule until there is evidence of progressive disease (PD), or until other withdrawal criteria are met.
Interventions
Cohort 1 10 milligrams/kilogram (mg/kg) intravenously (IV) administered on Days 1 and 8, every 3 weeks; Cohort 2 20 mg/kg IV administered every 2 weeks; Cohort 3 15 mg/kg IV administered on Days 1 and 8, every 3 weeks

Pre-assignment details
There were 3 cohorts and enrollment into the next cohort did not occur until all participants in the previous cohort completed 1 cycle of treatment or discontinued due to dose-limiting toxicity (DLT). Participants who completed Cycle 1 or had DLT during Cycle 1 are considered having completed study.
