This Phase I study will be conducted in 2 parts to examine safety and pharmacokinetics of escalating doses of intravenous ascorbic acid (AA) first in healthy volunteers followed by evaluation in oncology subjects. The study will be conducted in the Program in Integrative Medicine Infusion Clinic at the University of Kansas Medical Center in conjunction with the Program in Integrative Medicine, Kansas Cancer Research Institute, Department of Pharmacy, Department of Medical Oncology, the Division of Surgical Oncology,and with consultants from the NIH, and FDA.

The purpose of this study is to examine what happens when Vitamin C enters into the body, and the speed and ways it travels through the body, and the rate at which it exits the body in the urine. It is also necessary to determine if it is safe to give Intravenous Vitamin C at high doses.
