Study Description

Brief Summary:

The Principal Investigator believes that Vitamin E δ-Tocotrienol will slow the progression of pancreatic cancer cells. Therefore, the investigators must determine the safety and tolerability of Vitamin E δ-Tocotrienol in healthy participants before administering to cancer patients. The investigators will do this by giving participants a dose of up to1600 mg twice a day, not to exceed 3200 mg total for 14 consecutive days.

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

Detailed Description:

Participants will be accrued in cohorts of three. The decision to dose escalate will be made by the Cohort Review Committee (CRC) based on safety after the last subject in the current cohort has completed the Study Treatment Period. The study will consist of the following procedures:

• Pre-Treatment Period: The screening period must occur within 7 days of dosing.
• Study Treatment Period (14 days): Vitamin E δ-Tocotrienol will be administered orally twice daily for 14 consecutive days
• Post-Treatment Period: Subject will return to the study site 7 days after the dose of Vitamin E δ-Tocotrienol for an end-of-treatment assessment. On day 8 (± 2 days) after the last dose of study drug, the investigator will obtain follow-up information. Any serious adverse events (SAEs) present at 7 days after the last dose and possibly related to study drug will be followed until resolution, stabilization, or initiation of treatment that confounds the ability to assess the event.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Phase I Dose Escalation; Each investigator will be provided with adequate supplies of Vitamin E δ -Tocotrienol, which will be supplied as 100-mg, 200-mg, and 400-mg capsules. Vitamin E δ-Tocotrienol will be administered orally once. The dose administered to each subject will be fixed and based on cohort assignment. Doses will be administered at the clinical site during each protocol-defined visit.

Drug: Vitamin E δ-Tocotrienol; Vitamin E δ-Tocotrienol will be administered orally as a single agent twice daily for 14 consecutive days. Vitamin E δ-Tocotrienol is supplied as 100-mg, 200-mg, and 400-mg capsules. The first cohort will be dosed with δ-tocotrienol at 100 mg twice daily for 14 consecutive days. A minimum of 3 subjects is planned for each dosing cohort with Vitamin E δ-Tocotrienol dose escalation dependent on safety and available PK data from prior cohorts. At the MTD or MAD, 18 subjects will be enrolled.; Other Name: Delta-tocotrienol

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Treatment Related 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 maximum administered dose (MAD) or maximum tolerated dose (MTD) of Vitamin E δ-Tocotrienol administered twice daily for 14 days. Safety analyses and summary tables will include data collected for all subjects who receive at least one dose of study drug.

Secondary Outcome Measures :

1. Maximum Plasma Concentration (Cmax) of Vitamin E δ-Tocotrienol [ Time Frame: 3 Weeks Per Participant ]
   To determine the effects of dose on the plasma pharmacokinetic (PK) of Vitamin E δ-Tocotrienol following multiple dose administration in healthy subjects.
2. Pharmacodynamic (PD) Markers of Vitamin E δ-Tocotrienol Activity in Peripheral Blood [ Time Frame: Day 1, Day 8 Day 14 ]
   Peripheral blood mononuclear cells will be collected at each time point for examination of biomolecular markers not limited to Erk, p-Erk, AKT, p-AKT, p27, Ki-67, and exportin.
