A Study to Evaluate the Efficacy and Safety of Enlicitide Decanoate (MK-0616, Oral PCSK9 Inhibitor) Compared With Ezetimibe or Bempedoic Acid or Ezetimibe and Bempedoic Acid in Adults With Hypercholesterolemia (MK-0616-018) CORALreef AddOn

Phase 3

Completed

• Conditions: Hypercholesterolemia
• Interventions: Drug: Ezetimibe; Drug: Bempedoic Acid; Drug: Enlicitide Decanoate; Other: Placebo for Ezetimibe; Other: Placebo for Enlicitide Decanoate; Other: Placebo for Bempedoic Acid

• Registration Number: NCT06450366
• Lead Sponsor: Merck Sharp & Dohme LLC

Brief Summary

The main purpose of this study is to assess whether enlicitide decanoate is superior to ezetimibe or bempedoic acid or ezetimibe + bempedoic acid in reducing LDL-C in participants with hypercholesterolemia, and to evaluate its safety and tolerability. The primary study hypotheses are enlicitide decanoate is superior to ezetimibe, bempedoic acid, and ezetimibe + bempedoic acid on mean percent change from baseline in LDL-C at week 8.

Primary Outcome Measures

Name	Time	Method
Mean Percent Change from Baseline in LDL-C at Day 56	Baseline and Day 56	Blood samples will be collected at baseline and after 56 days of treatment to assess mean percentage change in LDL-C. The percent change from baseline in LDL-C at Day-56 will be reported.

Secondary Outcome Measures

Name	Time	Method
Mean Percent Change from Baseline in Apolipoprotein B (ApoB) at Day 56	Baseline and Day 56	Blood samples will be collected at baseline and on day 56 of treatment to assess mean percent change in ApoB. The percent change from baseline in ApoB at Day 56 will be reported.
Mean Percent Change from Baseline in Non-High-density Lipoprotein Cholesterol (Non-HDL-C) at Day 56	Baseline and Day 56	Blood samples will be collected at baseline and on day 56 of treatment to assess mean percent change in non-HDL-C. The percent change from baseline in non-HDL-C at 56 days will be reported.
Percentage of Participants Who at Day 56 Have an LDL-C <70 mg/dL and ≥50% Reduction from Baseline	Baseline and Day 56	The percentage of participants who have an LDL-C \<70 mg/dL and \>50% reduction from baseline at day 56 will be reported.
Percentage of Participants Who at Day 56 Have an LDL-C <55 mg/dL and ≥50% Reduction from Baseline	Baseline and Day 56	The percentage of participants who have an LDL-C \<55 mg/dL and \>50% reduction from baseline at day 56 will be reported.
Number of Participants With ≥1 Adverse Event (AE)	Up to Approximately 112 days	An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Percent Change from Baseline in Lipoprotein(a) Levels (Lp[a])	Baseline and Day 56	Blood samples will be collected at baseline and on day 56 of treatment to assess percent change in Lp(a) levels. The change from baseline at Day 56 will be reported.
Number of Participants Discontinuing from Study Therapy Due to AE	Up to Approximately 56 days	An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
