Phase 1b/2 study in combination with gemcitabine. In January 2005, we announced the enrollment of the first patient in a Phase 1b/2 study in combination with gemcitabine at the M.D. Anderson Cancer Center in Houston, Texas. The Phase 1b component is an open label dose escalation study, enrolling patients with advanced cancer, some of whom may have previously received gemcitabine. This component is being followed by a Phase 2 study exploring the use of ARQ 501 and gemcitabine in patients with newly diagnosed pancreatic cancer.
