The primary objective is to assess the effect of apraglutide on gastric emptying of liquids in healthy subjects, as measured by the PK of acetaminophen mixed with a liquid meal.

This is a single-center, double-blind, randomized, multiple-dose, parallel trial with a total duration of up to 50 days. The trial population will consist of healthy volunteers. Eligible subjects will be randomized to receive either subcutaneous (SC) apraglutide or matching placebo. The effect of apraglutide on gastric emptying of liquids will be assessed by the measure of PK of acetaminophen mixed with a liquid meal.

There will be two treatment periods, occurring according to the same sequence. In Period 1 acetaminophen will be given on Day 1, apraglutide/placebo will be injected on Day2. In Period 2 apraglutide/placebo will be injected on Day 9 and acetaminophen will be given on Day 10. This will allow to assess the PK of acetaminophen without the effect of apraglutide in Period 1, and to assess the PK of acetaminophen at the maximum concentration of apraglutide in Period 2.
