Summary

This study tested a weekly injection of pegzilarginase in 3 infants under 2 years old with arginase 1 deficiency, a rare genetic disorder that causes harmful buildup of arginine. The goal was to see if the drug safely lowers arginine levels and helps manage the condition. Because patients need ongoing treatment, this is considered disease control, not a cure.
