Biomarker Study of Neoadjuvant Vitamin E in Patients With Locally Treatable Prostate Cancer
Stopped early · Phase 3 · Has a placebo group
Conditions studied: Prostate Cancer
In brief
The purpose of this study is to find out if vitamin E can help treat prostate cancer. Vitamin E acts primarily as an anti-oxidant. By decreasing the oxidation in the cancer cell, the tumor cells may die. Vitamin E is a commonly used vitamin that has not been approved by the Food and Drug Administration for use in this type of cancer or for any known cancer. This study will test the hypothesis that vitamin E, in the setting of an oxidative stress such as smoking, can reduce prostate cancer related biomarkers in patients with localized prostate cancer in the neoadjuvant setting.
