LG Chem recently announced that the Company has submitted an IND application to the US FDA for its first independent global Phase 3 clinical trial of its new gout drug ‘Tigulixostat' (clinical program name: EURELIA_1 Study). LG Chem's strategy is to expand its life sciences business and to reach global markets such as the U.S. and Europe in various therapeutic areas in the upcoming years. In global Phase 3 clinical trial, Tigulixostat will be evaluated in 350 adult gout patients with hyperuricemia for safety and efficacy at Month 6 of treatment, and the data will be compared with that of the placebo-controlled group.

The primary end point is the patient ratio reaching below 6mg/dL of serum uric acid concentration after 6 months of treatment. Additionally, LG Chem will be submitting an application to the US FDA for a comparative study with ‘Allopurinol,' a first line treatment of gout. The Company's strategy is to prove distinguished efficacy and safety for long-term treatment through global clinical trial.

LG Chem aims to enter the global gout market in 2028 after obtaining US FDA approval for Tigulixostat as a first line treatment. Tigulixostat is an oral drug administered once daily. It inhibits enzymatic activity of ‘XO (Xanthine Oxidase),' thereby reducing production of uric acid, which is the primary cause of gout.

Results from the US Phase 2 clinical trial—primary end point set at a challenging level (achieving below 5mg/dL serum uric acid concentration)—confirmed the potential of Tigulixostat as a new gout treatment distinguished from pre-existing drugs, while also demonstrating safety similar to that of the placebo group.
