Study of High-Dose Intravenous (IV) Vitamin C Treatment in Patients With Solid Tumors

Completed · Phase 1

Conditions studied: Cancer

In brief

The primary purpose of this study is to evaluate the safety and tolerability of vitamin C (ascorbic acid) given by injection into the vein. The second and third purpose of conducting this study is to observe any evidence of tumor response to the vitamin C and compare the level of fatigue (weakness), pain control, ability to do things, and quality of life, before and after vitamin C is given.
