What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change From Baseline to Week 12 in Low-Density Lipoprotein Cholesterol (LDL-C)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analyzed for LDL-C. Baseline was defined as the mean of the LDL-C values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: ([LDL-C value at Week 12 minus Baseline value] divided by [Baseline Value]) multiplied by 100. Bempedoic Acid = BA. Percent change from Baseline in LDL-C was analyzed using an analysis of covariance (ANCOVA) model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate. In the ANCOVA model, missing LDL-C data at Week 12 were imputed using multiple imputation method taking into account adherence to treatment.

    Measured: Week 12

Secondary outcomes (7)
  1. Percent Change From Baseline to Week 12 in Non-high-density Lipoprotein Cholesterol (Non-HDL-C)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analysed for non-HDL-C. Baseline was defined as the mean of the non-HDL-C values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: ([non-HDL-C value at Week 12 minus Baseline value] divided by [Baseline Value]) multiplied by 100. Percent change from Baseline in non-HDL-C was analyzed using an ANCOVA model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate. In the ANCOVA model, missing non-HDL-C data at Week 12 were imputed using multiple imputation method taking into account adherence to treatment.

    Measured: Week 12

  2. Percent Change From Baseline to Week 12 in Total Cholesterol (TC)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analysed for TC. Baseline was defined as the mean of the TC values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: ([TC value at Week 12 minus Baseline value] divided by [Baseline Value]) multiplied by 100. Percent change from Baseline in TC was analyzed using an ANCOVA model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate. In the ANCOVA model, missing TC data at Week 12 were imputed using multiple imputation method taking into account adherence to treatment.

    Measured: Week 12

  3. Percent Change From Baseline to Week 12 in Apolipoprotein B (apoB)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analysed for apoB. Baseline was defined as the last non-missing value on or prior to Day 1. Percent change from baseline was calculated as: [(apoB value at Week 12 minus Baseline value) divided by (Baseline Value)] multiplied by 100. Percent change from Baseline in apoB was analyzed using an ANCOVA model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate. In the ANCOVA model, missing apoB data at Week 12 were imputed using multiple imputation method taking into account adherence to treatment.

    Measured: Week 12

  4. Percent Change From Baseline to Week 12 in High-sensitivity C-reactive Protein (hsCRP)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analysed for hsCRP. Baseline was defined as the last non-missing value on or prior to Day 1. Percent change from baseline was calculated as: [(hsCRP value at Week 12 minus Baseline value) divided by (Baseline Value)] multiplied by 100.

    Measured: Week 12

  5. Percent Change From Baseline to Week 12 in Triglycerides (TGs)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analyzed for TGs. Baseline was defined as the mean of the TGs values from the last two non-missing values on or prior to D 1. Percent change from baseline was calculated as: [(TGs value at Week 12 minus Baseline value) divided by (Baseline Value)] multiplied by 100. Percent change from Baseline in TGs was analyzed using an ANCOVA model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate.

    Measured: Week 12

  6. Percent Change From Baseline to Week 12 in High-density Lipoprotein Cholesterol (HDL-C)

    Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analyzed for HDL-C. Baseline was defined as the mean of the HDL-C values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: [(HDL-C value at Week 12 minus Baseline value) divided by (Baseline Value)] multiplied by 100. Percent change from Baseline in HDL-C was analyzed using an ANCOVA model with percent change from Baseline as the dependent variable, treatment as a fixed effects and Baseline as a covariate.

    Measured: Week 12

  7. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    TEAEs, defined as an adverse events (AEs) that began or worsened in severity after the first dose of double-blind study drug and prior to the last dose of double-blind study drug + 30 days, were collected and reported.

    Measured: Up to approximately 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bempedoic acid and Ezetimibe in people with Hypercholesterolemia and Atherosclerosis, run by Esperion Therapeutics, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Apr 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change From Baseline to Week 12 in Low-Density Lipoprotein Cholesterol (LDL-C) (time frame: Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03001076, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2020.
