Sanofi SAPhase III study met all endpoints, supporting regulatory submission for infantile-onset Pompe disease

Sanofi announced that the phase III Baby-COMET study evaluating Nexviazyme in patients with infantile-onset Pompe disease met all primary and secondary endpoints. The primary endpoint showed that treatment-naïve pediatric participants aged six months and younger remained alive and free of invasive ventilator support after 52 weeks of treatment. Secondary endpoints included the proportion of participants alive and free of invasive ventilation at 12 and 18 months of age, as well as improvements in other measures of disease progression. Based on this data, Sanofi plans to submit a regulatory filing in the United States seeking approval for Nexviazyme in infantile-onset Pompe disease in the second half of 2026. Nexviazyme is currently approved in the US for late-onset Pompe disease in patients aged one year and above, and is marketed as Nexviadyme in Europe where it is approved for both forms.
