About STA-4783

STA-4783 is a novel, injectable, small molecule investigational drug candidate that induces a potent oxidative stress response in cancer cells, driving programmed cell death and enhancing the activity of anti-cancer agents that act through the mitochondrial apoptosis pathway, including paclitaxel. In September 2006, Synta reported positive Phase 2b results for STA-4783 in combination with paclitaxel in a double-blind, randomized, multi-center clinical trial in patients with stage IV metastatic melanoma. In November 2006, Synta received Fast Track designation from the FDA for the development of STA-4783 in metastatic melanoma. Synta plans to initiate a pivotal Phase 3 clinical trial for STA-4783 in mid-2007 and one or more Phase 2 studies in other cancer indications later in the year.
