About this study

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 and doxorubicin pharmacokinetics. High-Risk * To estimate the maximum tolerated dose (MTD) and/or the recommended phase 2 dosage (RP2D) of selinexor in combination with ifosfamide, doxorubicin, pazopanib, and maintenance pazopanib in high-risk participants. * To characterize the pharmacokinetics of selinexor, pazopanib and doxorubicin in combination with ifosfamide in high-risk participants, to assess potential covariates to explain the inter- and intra-individual pharmacokinetic variability, and to explore associations between clinical effects and selinexor, pazopanib and doxorubicin pharmacokinetics. Secondary Objectives * To estimate the cumulative incidence of primary site local failure and distant metastasis-free, disease-free, event-free, and overall survival in participants treated on the risk-based treatment strategy defined in this protocol. * To define and describe the CTC…
