Outcome Measures

Primary Outcomes (2)

  • Change in Level of 13C 2-AAA in Plasma

    Alpha aminoadipic acid (2-AAA) concentration determined through mass spectrometry, quantified to standard. The change was calculated as the area under the curve from baseline to 6 hours post-lysine administration of isotope labeled 2-AAA.

    Baseline to 6 Hours post-lysine administration

  • Change in Level of 2-AAA in Urine

    Alpha aminoadipic acid (2-AAA) concentration determined through mass spectrometry, quantified to standard. The change was calculated as the total amount of 13C 2-AAA in micromoles excreted from Baseline to 6 hours.

    Baseline to 6 Hours post-lysine administration

Study Arms (1)
