PCI-24781 in Combination With Doxorubicin to Treat Sarcoma

Summary

The purpose of this research study is to determine the safety and maximum tolerated dose of PCI-24781 that can be given safely with doxorubicin (phase I) and the safety and efficacy of PCI-24781 when used in combination with doxorubicin (phase II) in patients with advanced sarcomas. The study drug, PCI-24781, is believed to regulate genes involved in tumor cell growth. The other study drug, doxorubicin, is considered a standard chemotherapeutic treatment for advanced sarcoma patients. We hypothesize that combining PCI-24781 with doxorubicin can overcome chemoresistance to doxorubicin.
