Acute and Chronic Hyperammonemia due to NAGS Deficiency In a retrospective case series of 23 NAGS deficiency patients treated with CARBAGLU, 17 of the 23 patients reported an adverse reaction. The most common adverse reactions (occurring in ≥ 13% of patients) were vomiting, abdominal pain, pyrexia, tonsillitis, anemia, diarrhea, ear infection, infections, nasopharyngitis, hemoglobin decreased, and headache. Table 1 summarizes adverse reactions occurring in 2 or more patients treated with CARBAGLU.

The average patient age (SD) was 9.2 years (7.7) and 12 (50 %) were males. CARBAGLU was administered at ...
