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

A Phase I, Randomized, Open-label, 4-period, 4-treatment, Single-dose, Cross-over Study to Assess the Relative Bioavailability of Laroprovstat/Ezetimibe Fixed Combination Drug Products to the Single Therapy Products in Healthy Adults

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.

Inclusion Criteria:

• Healthy male and female participants aged 18 to 55 years at the time of signing consent.
• All females must have a negative pregnancy test at the Screening Visit and on admission to the study site.
