Clinical Trial Summary

Hyperammonemia, which can cause brain damage, occurs in many different kinds of inborn errors of metabolism. The investigators propose to determine if short-term (3 day) treatment with N-carbamylglutamate can diminish hyperammonemia by enhancing ureagenesis in these patients. The investigators propose here a short-term (3 day) trial. If it succeeds, the investigators would consider more extensive long-term studies of the drug.


Clinical Trial Description

- To determine whether brief (3 day) treatment with N-carbamylglutamate can improve ureagenesis in adult healthy controls and patients with the following inborn errors of metabolism: N-acetylglutamate synthetase deficiency, propionic acidemia, methylmalonic acidemia, carbamylphosphate synthase deficiency, ornithine transcarbamylase deficiency and the syndrome of hyperammonemia, hypoglycemia and hyperinsulinemia (HHH Syndrome).

- To determine if such treatment improves other indicators of abnormal nitrogen metabolism such as elevated blood levels of glutamine, glycine and alanine. ;
