NRSTS2021, A Risk Adapted Study Evaluating Maintenance Pazopanib, Limited Margin, Dose-Escalated Radiation Therapy and Selinexor in Non-Rhabdomyosarcoma Soft Tissue Sarcoma (NRSTS)
The study participant has been diagnosed with non-rhabdomyosarcoma (NRSTS).
Primary Objectives
Intermediate-Risk
* To estimate the 3-year event-free survival for intermediate-risk patients treated with ifosfamide, doxorubicin, pazopanib, surgery, and maintenance pazopanib, with or without RT.
* To characterize the pharmacokinetics of pazopanib and doxorubicin in combination with ifosfamide in intermediate-risk participants, to assess potential covariates to explain the inter- and intra-individual pharmacokinetic variability, and to explore associations between clinical effects and pazopanib
