Synta opens phase II trial STA-9090 in GIST
STA-9090 is a synthetic, small molecule HSP90 inhibitor. It has a unique chemical structure different from earlier HSP-90 inhibitors that, like IPI-504, are first generation drugs based on a family of antibiotics called ansamycins. As a result, STA-9090 is likely to have a different toxicity profile.
