Overview
Brief Summary
This is a single center, Phase 1, randomized, open-label, single-dose, 4 treatment, 4-period, 4-sequence, crossover study designed to compare the pharmacokinetics (PK) of sapropterin from the Test and Reference products, and to evaluate the effect of food and the effect of water administration on the bioavailability of sapropterin from the Test product in healthy subjects.
.
Detailed Description
In each period, subjects will receive a single 10 mg/kg dose of sapropterin dihydrochloride on Day 1, under fasting or fed conditions, and with or without water, followed by 24 hours of PK sampling. The study will include a screening visit from Day -30 to Day -1. In each period, eligible subjects will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 2. There will be a washout period of at least 7 days between doses.
