Brief Summary:
This is a Phase 1, open-label, non-randomized, dose-finding, study of Vitamin E δ-Tocotrienol in subjects with resectable pancreatic tumors.

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Drug: Vitamin E δ-Tocotrienol Phase 1

Detailed Description:
Vitamin E tocotrienols have been shown to exhibit cancer-preventive activities in preclinical studies. Vitamin E tocotrienols are composed of α-, β-, δ-, and γ-tocotrienols. The investigators preclinical studies indicate that δ-tocotrienol possesses the most potent antitumor activity against pancreatic cancer. It is believed that this micronutrient may have a role in the prevention of pancreatic cancer in healthy participants who are at increased risk of developing the disease.

Study Type : Interventional  (Clinical Trial)

Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Phase I Dose-Escalation Study of the Safety and Pharmacokinetics of Vitamin E δ-Tocotrienol Following Single Dose Administration in Healthy Subjects
Study Start Date : September 2011

Arm Intervention/treatment
Experimental: Dose Escalation
Vitamin E δ-Tocotrienol will be administered orally as a single agent once. Vitamin E δ-Tocotrienol is supplied as 100-mg, 200-mg, and 400-mg capsules.
Drug: Vitamin E δ-Tocotrienol
The first cohort will be dosed with δ-tocotrienol at 200 mg. A minimum of 3 participants is planned for each dosing cohort with Vitamin E δ-Tocotrienol dose escalation dependent on safety from prior cohorts.
Other Name: Delta-tocotrienol



Primary Outcome Measures :
  1. Number of Participants With Adverse Events [ Time Frame: 3 weeks per participant ]
    The primary objective of this study is to evaluate the safety and tolerability of Vitamin E δ-Tocotrienol and to determine the minimally effective dose (MED) or maximum tolerated dose (MTD) of Vitamin E δ-Tocotrienol administered once. Safety will be assessed by standard clinical findings and laboratory tests. Toxicity grade is defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE)v.4.0. Ninety-five percent confidence intervals may be calculated for selected safety and exploratory variables.


Secondary Outcome Measures :
  1. Number of Participants With Pharmacokinetic (PK) Markers of Vitamin E δ-Tocotrienol [ Time Frame: 3 weeks per participant ]
    Pharmacokinetic (PK) markers of Vitamin E δ-Tocotrienol in the plasma, urine, and neoplastic tissue of participants with pancreatic neoplasia. To determine the effects of dose on the plasma pharmacokinetic (PK) of Vitamin E δ-Tocotrienol when orally administered as a single dose in healthy subjects. Ninety-five percent confidence intervals may be calculated for selected safety and exploratory variables. Dose escalation will be based on safety and available PK data.

  2. Number of Participants With Pharmacodynamic (PD) Markers of Vitamin E δ-Tocotrienol [ Time Frame: 3 weeks per participant ]
    Pharmacodynamic (PD) Markers of Vitamin E δ-Tocotrienol in the plasma, urine, and neoplastic tissue of participants with pancreatic neoplasia. To evaluate pharmacodynamic (PD) markers of Vitamin E δ-Tocotrienol activity in peripheral blood. Ninety-five percent confidence intervals may be calculated for selected safety and exploratory variables. Correlative analysis of PD data will be done.
