Brief Summary

The purpose of this study is to assess how well laroprovstat and rosuvastatin combined in a single tablet to be taken by mouth works compared with laroprovstat and rosuvastatin individual tablets taken by mouth (relative bioavailability) in healthy adults.

Detailed Description

This is a randomized, open-label, 3 or 4-period, single-dose, two-cohort, multi-center, crossover study. The study will comprise of a screening period (21 Days), 3 or 4 treatment periods (depending on cohort assignment) and washout period (14 Days, starting after dosing on Study Day 1 of a given treatment period). Each treatment period consists of dosing on Day 1; any subsequent treatment period will not start sooner than 14 days following dosing in the previous treatment period.
