Targeting Senescence to Reduce Osteoarthritis Pain and cartilagE Breakdown (ROPE)
Symptomatic knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Increasing age, obesity, and previous injury increase the lifetime risk of knee OA, but these factors are also independently associated with increased cellular senescence. Senescent cells accumulate in many tissues and contribute to chronic pathologies, linked to the secretion of pro-inflammatory factors collectively known as the senescence-associated secretory phenotype. In OA, senescent cells promote production of cytokines, chemokines, and matrix-degrading enzymes involved in progressive cartilage breakdown. The senolytic supplement fisetin alters the inflammatory and catabolic cartilage responses, which may clinically lessen OA pain while also slowing progressive cartilage breakdown. The purpose of this double-blind, randomized clinical trial is to compare 2 fisetin dosing regimens versus placebo. Sixty patients with mild to moderate knee OA will be assessed at baseline and 3 months in an effort to: determine if 2 different fisetin dosing regimens lessen pain and functional impairment compared to placebo, compare progressive changes in senescent cell activity and biomarkers of cartilage degradation between different fisetin dosing regimens and placebo, and assess acceptability and feasibility of 2 fisetin dosing regimens.

Conditions
- Osteoarthritis, Knee
Interventions
- High-dose/short-duration Fisetin
- Low-dose/sustained-duration Fisetin
- Oral placebo capsule
Primary outcomes
- Change in markers of liver toxicity — Change between baseline and 3-month follow-up
The change in 2 markers of liver toxicity between baseline and 3-month follow-up will be assessed. Alanine amino transferase (ALT) and aspartate amino transferase (AST) are enzymes found mostly in the cells of the liver and kidney, and heart and liver, respectively. Both are useful tests for detecting liver damage. - Change in markers of kidney toxicity — Change between baseline and 3-month follow-up
The change in 2 markers of kidney toxicity between baseline and 3-month follow-up will be assessed. Blood urea nitrogen (BUN) is a waste product filtered out of the blood by the kidneys. As kidney function decreases, the BUN level rises. Creatine kinase (CK) is also an enzyme that is used to assess kidney function. Higher CK values are associated with greater burden on the kidneys. - Change in markers of tumor lysis syndrome — Change between baseline and 3-month follow-up
Tumor lysis syndrome is characterized by high blood potassium, low blood calcium, and high blood uric acid. The change in potassium, calcium and uric acid between baseline and 3-month follow-up will be assessed.
