We present the case of a 42-year-old female with recurrent ES with pulmonary metastases who, after progressing on anti-IGF-1R monotherapy with figitumumab (CP-751,871, NCT00560235), achieved complete remission in a phase I clinical trial (NCT00976508) that combined figitumumab IGF-1R-inhibition with growth hormone receptor antagonist pegvisomant. Here, IGF1R is linked to Ewing sarcoma.
