A Phase I, Cross-over Study Comparing the Relative Bioavailability of Laroprovstat Plus Ezetimibe Fixed Combination Drug Products Versus Their Single Therapy Products in Healthy Adults

Phase 1Active Not RecruitingNCT07622433

AstraZeneca18 enrolled

Overview

The purpose of this study is to assess how well laroprovstat and ezetimibe combined in a single tablet to be taken by mouth works and what the body does to the drug (pharmacokinetics) compared with laroprovstat and ezetimibe individual tablets to be taken by mouth (relative bioavailability) as well as to see if there is any effect of eating compared to fasting (food effect) in healthy adults.

This is a randomized, open-label, 4-period, single-dose, cross-over study. The study will comprise of a screening period, 4 treatment periods, and 3 washout periods. The following treatments will be given during the study: * Treatment A: laroprovstat/ezetimibe fixed combination drug product (FCDP) test formulation in fasted state * Treatment B: laroprovstat tablet plus ezetimibe reference formulations in fasted state * Treatment C: laroprovstat/ezetimibe FCDP test formulation in fed state * Treatment D: laroprovstat/ezetimibe FCDP test formulation-slow variant in fasted state Participants will be randomly assigned to either of the 3 treatment sequences: ABCD, BCAD, or CABD.
