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

June 3, 2026 updated by: AstraZeneca

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.

Detailed Description

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.

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal Vivli.org. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared.

IPD Sharing Time Frame

AstraZeneca will meet or exceed data availability as per the commitments made to the EFPIA PhRMA Data Sharing Principles. For details of our timelines, please rerefer to our disclosure commitment at https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

IPD Sharing Access Criteria

When a request has been approved AstraZeneca will provide access to the anonymized individual patient-level data via secure research environment Vivli.org.

Signed Data Usage Agreement (non-negotiable contract for data accessors) must be in place before accessing requested information.
