Clinical Trials

Multiple clinical trials evaluate green tea formulations containing catechins across Phase 1 through Phase 3 and unassigned phase classifications. These studies address diverse indications, including metabolic inflammation and endotoxemia in obesity, steroid profiling in healthy volunteers for sports doping control, progression of multiple system atrophy, and diabetic nephropathy with hypertension. Sponsored primarily by academic institutions, research foundations, and anti-doping organizations, these registered trials include completed studies alongside those with unknown recruitment status.

Compliance for Clinical Use

Mechanism and Biochemical Profile

(+)-Gallocatechin selectively binds to human cannabinoid receptors and exerts antioxidant properties, thereby inhibiting downstream reactive oxygen species accumulation and inflammatory signaling pathways. This cellular modulation mitigates oxidative stress and tissue damage, offering potential therapeutic relevance in managing metabolic inflammation, diabetic nephropathy, and neurodegenerative disorders investigated in clinical settings.

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.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
