Phase 1/Phase 2 |
Detailed Description
This is a Phase I/II randomized, double-blind, placebo-controlled clinical trial that will be conducted at The Steadman Clinic (TSC) and Steadman Philippon Research Institute (SPRI). The purpose of this study is to evaluate the clinical efficacy of Fisetin (FIS), a dietary supplement, in symptomatic knee osteoarthritis (OA) patients. Key aspects of this proposal include the investigator's well-developed methodologies to measure and compare systemic senescence-associated secretory phenotype (SASP) including inflammatory biomarkers and senescent cells, and collect magnetic resonance images, self-reported outcomes, physical performance and other objective clinical data. Given the drug FIS has been empirically demonstrated to reduce senescent cell burden, the main objective(s) are to determine 1) the safety of FIS during dosing and 2) whether FIS reduces senescent cells, pro-inflammatory and cartilage degenerating SASP markers, and reduces OA-symptoms leading to improved joint health and function.
