XORTX Therapeutics Inc. (XRTX) reports that it has initiated clinical and commercial manufacturing activities for XORLO™, its proprietary oxypurinol formulation within the XRx-026 program for gout. Contract production of GMP-grade oxypurinol drug substance and commercial-scale XORLO tablets has begun to supply the planned XRX-OXY-102 clinical study and to generate data intended to support a future US FDA marketing application.
The company is working with a contract manufacturing partner to produce commercial drug batches, with validation and stability data from this work expected to support a New Drug Application. XORTX characterizes advancement of XRx-026 through NDA filing as a strategic priority and indicates that this manufacturing progress is one part of a broader plan to move XRx-026 toward potential FDA marketing approval.
The disclosure also highlights the clinical need in gout, where current oral xanthine oxidase inhibitors have tolerability and safety limitations, and positions XORLO as an alternative option with a differentiated safety and efficacy profile under development. XORTX notes additional pipeline programs targeting kidney and metabolic diseases related to purine metabolism and uric acid production.

XORTX Therapeutics Inc., a late-stage clinical pharmaceutical company focused on kidney and uric-acid–related diseases, reported an interim net loss of $2.50 million for the six months ended June 30, 2026, compared with $1.42 million a year earlier. Total assets increased to $6.18 million from $2.68 million, mainly due to capitalizing the acquired VB4-P5 renal anti-fibrotic program as an intangible asset.
Cash was $0.99 million with working capital of $1.76 million, while management discloses a monthly cash burn of about $296,000 and states there is a material uncertainty casting significant doubt on the company’s ability to continue as a going concern. During the period XORTX issued equity and 3.17 million pre-funded warrants, and completed the VB4-P5 acquisition using 154,544 shares and pre-funded warrants valued at $1.87 million.

Shareholders, including those in Canada, will continue to have full trading access to XORTX shares on Nasdaq, and no shareholder action is required.
