This study includes two parts. Part One will evaluate two ALLN-346 formulations, a fast release and a slower sustained release. Subjects will receive a single tablet of each formulation and a capsule of each formulation at separate assessment visits. Subjects will attend a maximum of 4 assessment visits. The primary purpose of this part of the study is to understand the gastrointestinal transit time and disintegration behaviour of the formulations in vivo in normal healthy volunteers when ALLN-346 formulations are given with light meal.~Part Two will involve a second cohort of subjects and will comprise further scintigraphic studies on one or both formulation(s) from Part One in fasted and/or fed states. Subjects will attend a maximum of 4 assessment visits, the number of treatment arms will be decided following completion of Part One.
