Innovent's Tigulixostat Unveils Breakthrough Phase 2 Results, Offering New Hope for Gout Patients

Innovent Biologics, a leading name in biopharmaceutical innovation, has announced groundbreaking Phase 2 clinical trial results for its novel xanthine oxidase inhibitor (XOI), Tigulixostat (IBI128), in patients suffering from gout. These highly anticipated findings were prominently featured and published at the prestigious ACR Convergence 2024, signaling a significant leap forward in the quest for more effective and safer gout management.

Gout, a painful and debilitating form of inflammatory arthritis caused by excessive uric acid in the blood, affects millions worldwide.

While existing treatments aim to lower serum uric acid (sUA) levels, many patients still struggle with achieving optimal control or experience adverse effects. This is where Tigulixostat, a potent, selective, and orally active XOI, emerges as a potential game-changer.

The multi-center, randomized, double-blind, and placebo-controlled Phase 2 study rigorously evaluated the efficacy and safety of Tigulixostat across various dosages (5mg, 10mg, 20mg, and 40mg) over a 12-week period.

The results were nothing short of impressive. Tigulixostat demonstrated a dose-dependent and highly significant reduction in sUA levels, achieving the target of <6 mg/dL in a remarkable proportion of patients. Specifically, 77.8% to 94.4% of patients in the treatment groups reached this crucial threshold, a stark contrast to only 5.9% in the placebo group.

Even more compelling, a substantial number of patients (44.4% to 77.8%) achieved an sUA level of <5 mg/dL, indicating a deeper and potentially more beneficial reduction.

The drug also exhibited a rapid onset of action, with sUA levels dropping significantly within a week of treatment initiation and maintaining these reduced levels throughout the study duration. This sustained efficacy is a critical factor for long-term gout management.

Beyond its powerful efficacy, Tigulixostat also boasts an excellent safety and tolerability profile, comparable to that of the placebo.

Most reported adverse events (AEs) were mild to moderate in severity, and importantly, no new or unexpected safety signals were identified. This robust safety profile is particularly encouraging, as it addresses a key concern with some current XOI therapies.

Dr. Huiyong Sun, the lead investigator of the Phase 2 study, expressed enthusiasm for these results, stating that Tigulixostat holds immense promise as a new therapeutic option, especially for patients who are intolerant or unresponsive to existing XOIs.

The drug’s unique mechanism, coupled with its superior efficacy and favorable safety, positions it as a strong contender to reshape the landscape of gout treatment.

As Innovent Biologics continues to advance Tigulixostat through its development pipeline, the medical community and patients alike will be eagerly anticipating its further progress.

These Phase 2 results represent a beacon of hope, suggesting that a new, highly effective, and well-tolerated treatment for gout may soon be within reach, offering improved quality of life for countless individuals battling this chronic condition.
