The primary efficacy outcome will be assessed by measuring change from baseline in plasma D5-Phe AUC over 24 hours after D5-Phe administration
Toxicity is graded in accordance with the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.03. Adverse events (AEs) are reported based on clinical laboratory tests, vital sign and weight measurements, physical examinations, electrocardiograms, and any other medically indicated assessments, including subject interviews, from the time informed consent is signed through the end of the safety follow-up period. AEs are considered to be treatment emergent (TEAE) if they occur or worsen in severity after the first dose of study treatment. TEAEs are considered treatment-related if relationship to study drug is possibly related, probably related, or definitely related.
