6. ADVERSE REACTIONS NAGS deficiency : Most common adverse reactions (≥13%) are vomiting, abdominal pain, pyrexia, tonsillitis, anemia, diarrhea, ear infection, infections, nasopharyngitis, hemoglobin decreased, and headache.

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 a dosage of 150 mg/kg/day for patients ≤15 kg or 3.3 g/m 2 /day for patients >15 kg, divided into 2 doses, for a median duration of 4.14 days. At least 1 adverse reaction was reported during the course of hyperammonemic episodes in 42% of hyperammonemic episodes. The most common adverse reactions (≥5%) during hyperammonemic episodes were neutropenia, anemia, vomiting, electrolyte imbalance, decreased appetite, hypoglycemia, lethargy/stupor, encephalopathy and pancreatitis/lipase increased. Table 2 summarizes adverse reactions (≥2%) during hyperammonemic episodes in patients with PA or MMA treated with CARBAGLU or placebo.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure. Psychiatric disorders : mania Skin and subcutaneous tissue disorders : pruritus, rash including rash erythematous, rash maculopapular, rash pustular
