Study summary

The overall objective of the Cholesterol Lowering via Bempedoic Acid/Ezetimibe, an ACL-Inhibiting Regimen in Acute Coronary Syndrome ACS (CLEAR ACS) study is to determine the efficacy, safety, and tolerability of bempedoic acid/ezetimibe (BA/E) in a contemporary and real-world population, enriched for older adults, women, and underrepresented racial/ethnic groups, of adults with a recent acute coronary syndrome (ACS) event independent of use of statin therapy before the ACS event.

Read the detailed description

The CLEAR ACS study is a prospective, virtual, electronic health record (EHR)-based, randomized, double-blind, placebo-controlled, parallel-group, pragmatic clinical trial (PCT) embedded within Kaiser Permanente Northern California's fully integrated and learning health care delivery system. The EHR will be screened in real-time for potentially eligible participants across all Kaiser Permanente Northern California hospitals using validated diagnostic and procedural codes, disease registries, laboratory values, pharmacy dispensing information, and sociodemographic data sources. Eligible patients that provide informed consent will be randomized in a 1:1 allocation ratio to an initial 12 weeks of blinded bempedoic acid/ezetimibe (BA/E) vs. matching placebo followed by a 12-week open-label extension phase where all patients will receive open-label, unblinded bempedoic acid/ezetimibe.

What researchers measure

Primary outcomes

  1. To evaluate the efficacy of BA/E vs. matching placebo on LDL-C level following a recent ACS event.

    Percent (%) change from baseline to week 12 in LDL-C level

    Time frame: 0-12 weeks

Secondary outcomes

  1. To determine the efficacy of BA/E vs. matching placebo on the lipid profile following a recent ACS event.

    - Percent (%) change from baseline to week 12 in high-density lipoprotein cholesterol (HDL-C)

    Time frame: 0-12 weeks

  2. To determine the efficacy of BA/E vs. matching placebo on the lipid profile following a recent ACS event.

    - Percent (%) change from baseline to week 12 in non-HDL-C

    Time frame: 0-12 weeks

  3. To determine the efficacy of BA/E vs. matching placebo on the lipid profile following a recent ACS event.

    - Percent (%) change from baseline to week 12 in total cholesterol (TC)

    Time frame: 0-12 weeks

  4. To determine the efficacy of BA/E vs. matching placebo on the lipid profile following a recent ACS event.

    - Percent (%) change from baseline to week 12 in triglyceride (TGs) levels

    Time frame: 0-12 weeks

Other outcomes

  1. To assess the safety and tolerability of BA/E vs. matching placebo following a recent ACS event.

    - Proportion (%) of adverse events (AEs) leading to permanent study drug discontinuation and unexpected serious AEs (SAEs) at 12 weeks

    Time frame: 0-12 weeks

  2. To explore the clinical effectiveness of BA/E vs. usual care on all-cause and cause-specific morbidity and mortality following a recent ACS event.

    - Rate (# of events per 100 person-years) of all-cause mortality (ACM)

    Time frame: 0-12 weeks

  3. To explore the clinical effectiveness of BA/E vs. usual care on all-cause and cause-specific morbidity and mortality following a recent ACS event.

    - Rate (# of events per 100 person-years) of MACE (3-point) = death due to any cause, MI, and/or stroke/TIA

    Time frame: 0-12 weeks

  4. To explore the clinical effectiveness of BA/E vs. usual care on all-cause and cause-specific morbidity and mortality following a recent ACS event.
