A Study of Enlicitide Decanoate (MK-0616 Oral PCSK9 Inhibitor) in Adults With Heterozygous Familial Hypercholesterolemia (MK-0616-017) CORALreef HeFH

Phase 3
Completed
Conditions
Hypercholesterolemia
Familial Hypercholesterolemia
Interventions
Registration Number
NCT05952869
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The goal of this study is to evaluate the efficacy, safety, and tolerability of enlicitide decanoate in adult participants with heterozygous familial hypercholesterolemia. The primary hypothesis is that enlicitide decanoate is superior to placebo on mean percent change from baseline in low-density lipoprotein cholesterol (LDL-C) at Week 24.

Primary Outcome Measures
NameTimeMethod
Mean percent change from baseline in low-density lipoprotein cholesterol (LDL-C) at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess mean percent change in LDL-C.

Number of participants with one or more adverse events (AEs)Up to ~60 weeks

An AE is 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.

Number of participants who discontinue study drug due to an AEUp to ~52 weeks

An AE is 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.

Secondary Outcome Measures
NameTimeMethod
Mean percent change from baseline in LDL-C at Week 52Baseline and Week 52

Blood samples will be collected at baseline and at Week 52 to assess mean percent change in LDL-C.

Mean percent change from baseline in non-high-density lipoprotein cholesterol (HDL-C) at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess mean percent change in non-HDL-C.

Mean percent change from baseline in apolipoprotein B (ApoB) at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess mean percent change in ApoB.

Percent change from baseline in lipoprotein(a) (Lp[a]) at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess percent change in Lp(a).

Percentage of participants with LDL-C <70 mg/dL and ≥50% reduction from baseline at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess the percentage of participants who have LDL-C \<70 mg/dL and ≥50% reduction from baseline.

Percentage of participants with LDL-C <55 mg/dL and ≥50% reduction from baseline at Week 24Baseline and Week 24

Blood samples will be collected at baseline and at Week 24 to assess the percentage of participants who have LDL-C \<55 mg/dL and ≥50% reduction from baseline.
