Measure
Gemcitabine + High-Dose Ascorbate
Subjects will receive ascorbate, 75g, on Days 1, 2, 8, 9, 15 and 16 of a 28-day cycle. Gemcitabine will be administered on Days 1, 8 and 15, after the infusion of ascorbate. Concomitant treatment will continue for 6 cycles. Patients whose disease has not progressed while receiving gemcitabine and ascorbate and who are tolerating therapy may continue either single agent gemcitabine or concomitant treatment beyond 6 cycles at the discretion of the investigator. Ascorbate: Following 15g test dose, 75g administered on Days 1, 2, 8, 9, 15 and 16 of a 28-day cycle Gemcitabine: Administered on Days 1, 8 and 15, after the infusion of ascorbate
