About

The Purpose of this study is to assess the relative bioavailability, dose proportionality, the impact of food on the rate and extent of absorption, palatability of the selected pediatric formulation of maribavir and the safety and tolerability of two candidate pediatric formulations and the adult tablet formulation of maribavir in healthy participants.

Full description

The study will be conducted in two parts (Part 1 and Part 2). Part 1 consists of three treatment periods in six sequences and part 2 consists of four treatment periods in four sequences. In Part 1 two pediatric candidate powder formulations will be compared with maribavir 200mg tablet under fasted conditions in regards to their bioavailability and palatability. In Part 2 dose proportionality and impact of food (a high-fat meal) on the rate and extent of absorption of the selected pediatric formulation will be assessed. The pediatric formulation which will be evaluated in Part 2 will be chosen based on the results of planned analysis of Part 1 PK and palatability data from two candidate pediatric formulations and the doses to be evaluated in Part 2 may be adjusted based on relative bioavailability of the selected pediatric formulation (powder for oral suspension) to the Phase 3 tablet formulation observed in Part 1.
