Acute illness at the time of either the pre-study medical evaluation or dosing. 3. All laboratory values reflecting hepatic function must be with in 10% of the upper range of normal in order to be considered not clinically significant. 5. Subjects who have known urea cycle disorders which are a group of uncommon genetic abnormalities (e. g. ornithine transcarbamylase deficiency). 6. Donation or loss of a significant volume of blood or plasma (> 450 mL) within 28 days prior to the initial dose of study medication. 7.
