Ongoing

Objective:
 In this study, we intend to determine Gamma-Delta Tocotrienol’s (GDT) safety and tolerability in patients with castrate-resistant prostate cancer (CRPC). In addition, GDT’s pharmacokinetic profile in this cohort of patients will be investigated.

Study Type: Interventional

Study Design: Dose-escalation, pharmacokinetics study

Subjects: Castrate-resistant prostate cancer patients

Intervention: Gamma-Delta Tocotrienol (GDT; Davos Life Science Pte Ltd)

Primary Outcome:

  • Safety and tolerability
  • GDT isomer plasma concentration [ time frame: 0, 1, 2, 3, 4, 6, 8, 10, 14, 24 hours ]

Secondary Outcome: Circulating tumor cell (CTC) levels and inflammatory biomarkers (IL-8, MCP-1, MIP-1 alpha, IFN-gamma, IL-1B, IL-4, IL-6, IL-10, IL-12 (p70), IL-17A, Il-23, IL-27, TNF-alpha, MIP-3 alpha, CRP) [time frame: baseline and day 22]

Methodology: During pharmacokinetic evaluation wherein GDT will be taken as a single dose, participants will receive oral GDT for 21 days at 400, 800, 1600, 2400 and 3200 mg/day for 21 days. Pharmakokinetic and safety profiles will be evaluated on the 8th, 15th and 22nd day.
