Advanced soft tissues sarcomas (STS) have limited therapeutic options. Sorafenib (BAY 43–9006) is a multi-targeted tyrosine kinase inhibitor of raf, VEGFR1-3, PDGFRB, flt-3, and c-kit. We tested sorafenib at a dose of 400 mg BID in patients with advanced sarcomas of vascular derivation (VS), high grade liposarcomas and leiomyosarcomas who had received 0–1 prior regimens for advanced disease. Fifty one patients were accrued, with thirty-seven evaluable for toxicity and response. There were no unexpected side effects and no confirmed responses. Median progression free survival and overall survival were 3 months and 17 months, respectively. Six of 8 patients in the VS cohort had prolonged clinical benefit (stable disease or better), resulting in a median progression free survival of 5 months, compared with 2–3 months for liposarcoma and leiomyosarcomas respectively. Sorafenib, at this dose and schedule, did not result in RECIST responses in VS, liposarcoma or leiomyosarcoma.
