A Study of R1507 in Participants With Recurrent or Refractory Sarcoma

This study will evaluate the efficacy and safety of R1507 in participants with recurrent or refractory sarcoma. Eight cohorts of sarcoma participants will be studied in parallel. Cohort 1: Ewing's sarcoma primary cohort defined as participants who have relapsed less than or equal to (<=) 24 months from diagnosis, received at least two prior chemotherapy programs and are unresectable. Cohort 2: Ewing's sarcoma non-primary (secondary) cohort defined as participants who have relapsed greater than or equal to (>=) 24 months from diagnosis or have only received one prior chemotherapy program. Cohort 3: Expanded Ewing's sarcoma defined as participants with recurrent or relapse regardless of prior number of salvage regimens and regardless of time of relapse. Cohort 4: participants with osteosarcoma. Cohort 5: Participants with synovial sarcoma. Cohort 6: Participants with rhabdomyosarcoma Cohort 7: Participants with alveolar soft part sarcoma (7a), desmoplastic small round cell tumors (7b), extraskeletal myxoid chondrosarcoma (7c), clear cell sarcoma (7d), myxoid liposarcoma (7e). Cohort 8: Participants with unspecified sarcoma diagnosis. Participants in the expanded Ewing's sarcoma Cohort 3 will receive 27 milligrams (mg)/kilogram (kg) every 3 weeks intravenously (IV). All other participants will receive R1507 9 mg/kg IV weekly. The anticipated time on study treatment is until disease progression or unacceptable adverse events, withdrawal or death.
