简要总结
The purpose of this study is to determine the safest dose of the study drug Vitamin E Delta-tocotrienol, how often it should be taken, and how well people with pancreatic tumors tolerate Vitamin E Delta-tocotrienol.
详细描述
Delta-tocotrienol is a natural Vitamin E compound that has been consumed by humans as a dietary supplement. The Food and Drug Administration (FDA) has not approved it for sale as a drug. Vitamin E Delta-tocotrienol is being investigated for the prevention and treatment of pancreatic tumors. The usefulness of the Vitamin E Delta-tocotrienol in treating human tumors is unknown.
This study consists of the following: (1) a Pre-Treatment Period in which participants are consented and qualified for the study; (2) a Study Treatment Period in which participant will receive Vitamin E δ-Tocotrienol administered orally twice daily for 14 (±2) consecutive days and once on the day of surgery, with associated pharmacokinetic and pharmacodynamic sampling; (3) a Post Treatment Period in which laboratory and physical examinations are performed. Adverse events will be recorded throughout the study.
