STA-9090
DrugThis is a dose-escalation study. The first cohort will consist of three patients who will receive STA 9090 (ganetespib)during a 1-hour infusion once per week for three consecutive weeks followed by a 1 week dose-free interval. Subsequent cohorts will receive higher amounts of STA-9090 (gantespib) provided that the previous dose was well tolerated during cycle 1 (week 1 - 4). Dose escalation will continue until the maximum tolerated dose (MTD) is determined.
