Scilex Holding Company (Nasdaq: SCLX, “Scilex” or “Company”), an innovative revenue-generating company focused on acquiring, developing and commercializing non-opioid pain management products for the treatment of acute and chronic pain, today announced presentation of data at the 2024 American College of Rheumatology Convergence conference to be held at the Walter E.

Title: Prophylaxis of Gout Flares in Patients with Renal Impairment: Dosing Adjustments with Colchicine Oral Solution Informed by a Pharmacokinetic Model

Authors: Jaymin Shah, PhD, FCP; Elaine K. Chan, PharmD; Dmitri Lissin, MD

Presentation: Saturday, November 16, 2024, at 10:30 AM ET - 12:30 PM ET

• GLOPERBA® (colchicine oral solution) is the first and only liquid formulation of colchicine that offers precision dosing for at risk gout patients.
• Scilex recently received FDA approval for an updated GLOPERBA® label, which reflects dosing adjustments in various clinical situations. Unlike other colchicine formulations, GLOPERBA® allows reduction of daily dose in patients with severe renal impairment (0.3 mg/day).
• Data to be presented summarizes pharmacokinetic model-derived dosing for at-risk moderate and severe chronic kidney disease patients who require lower precision dosing, not offered by other colchicine formulations of tablets and capsules currently available on the market.
