Clinical Trials

A clinical trial evaluated the safety, metabolic properties, and dose-escalation pharmacokinetics of citrus extract constituents, such as naringenin, to support its development as an anticancer agent. Sponsored by research institutions including the Pennington Biomedical Research Center and the Louisiana Clinical and Translational Science Center, this completed Early Phase I study established foundational pharmacokinetic parameters and safety characteristics required for further therapeutic advancement.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Citrus extract bioactive flavonoids modulate key pro-survival signaling cascades and cellular oxidative pathways, thereby inhibiting oncogenic cell proliferation and promoting programmed cell death. This antiproliferative and chemopreventive mechanism provides the biological rationale for evaluating the extract's safety profile and single-dose pharmacokinetic characteristics in early-phase clinical trials.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
