Sanofi SANexviazyme met all endpoints in phase 3 study for infantile-onset Pompe disease, supporting label extension

Sanofi announced that its enzyme replacement therapy Nexviazyme met all primary and secondary endpoints in the Baby-COMET phase 3 study for treatment-naïve infants with infantile-onset Pompe disease. The primary endpoint was met, with participants alive and free of invasive ventilation at 52 weeks, and all secondary endpoints were also met, including ventilator-free survival at 12 and 18 months of age. The results will be presented at the 19th International Congress on Neuromuscular Diseases on July 8, 2026, and will support a US regulatory submission for a label extension anticipated in the second half of 2026. Nexviazyme was well tolerated with no serious treatment-related adverse events, and safety was consistent with its established profile. The therapy is already approved in multiple countries for Pompe disease, including late-onset Pompe disease in the US since 2021.
