Executive Summary

XORTX announced plans to submit an IND to the FDA in Q4 2026 for its XRx-026 gout program (XORLO formulation of oxypurinol), targeting a $700M+ U.S. market opportunity. The filing outlines a regulatory path toward an NDA submission in approximately one year, contingent on successful completion of a two-part clinical trial and sufficient funding. This is a pre-clinical milestone announcement with no new clinical data, making it a forward-looking catalyst rather than a material event.
