Details and patient eligibility

About

The primary objective of this study is to determine the single-dose pharmacokinetics (PK) of A4250 when administered after a high-fat meal and when sprinkled on applesauce in healthy adult subjects.

Full description

This is an open-label, randomized, 3-way crossover, food-effect and sprinkle study. On Day 1 of each period, subjects will receive a single oral dose of A4250 under 1 of 3 conditions: fasting, following a high-fat, high-calorie breakfast, or sprinkled on applesauce. Subjects will receive A4250 under each condition on one occasion. Blood samples for PK analysis will be collected for 18 hours following each study drug administration. There will be a washout period of at least 7 days between doses. Study participants will be contacted approximately 14 days after the last study drug administration to determine if any adverse event (AE) has occurred since the last study visit.
