What's Happening?
Travere Therapeutics has presented new data on pegtibatinase at the International Congress of Inborn Errors of Metabolism. The data from the Phase 1/2 COMPOSE study shows significant reductions in disease-related metabolites in patients with classical homocystinuria (HCU). Pegtibatinase demonstrated a 53.5% reduction in total homocysteine and a 67.1% reduction in methionine over 50 weeks. The treatment was well-tolerated, with no new safety signals observed. Travere plans to restart enrollment in the Phase 3 HARMONY Study in 2026, aiming to establish pegtibatinase as a disease-modifying therapy for HCU.
Why It's Important?
The development of pegtibatinase as a treatment for classical HCU addresses a significant unmet need in rare disease management. Current treatments are limited, and pegtibatinase offers a potential breakthrough in reducing toxic metabolite levels associated with severe complications. This advancement could improve the quality of life for patients and reduce healthcare costs associated with managing complications. The data supports Travere's efforts to secure regulatory approval, which could lead to increased investment in rare disease therapies and influence future research directions.
What's Next?
Travere Therapeutics is preparing to restart the Phase 3 HARMONY Study in 2026, which will further evaluate the efficacy and safety of pegtibatinase. Successful results could lead to regulatory approval and commercialization, providing a new treatment option for HCU patients. The company will continue to engage with regulatory bodies and stakeholders to advance the development of pegtibatinase, potentially setting a precedent for future rare disease therapies.
