A Study of Enlicitide Decanoate (MK-0616, an Oral PCSK9 Inhibitor) in Children and Adolescents With Heterozygous Familial Hypercholesterolemia (MK-0616-029)
An Operationally Seamless Phase 2/3 Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of Enlicitide Decanoate in Pediatric Participants With Heterozygous Familial Hypercholesterolemia
Merck Sharp & Dohme LLC
153 participants

INTERVENTIONAL
Conditions
Summary
This study is designed to learn if enlicitide decanoate is safe and effective to treat children and adolescents with heterozygous familial hypercholesterolemia (HeFH) and high amounts of low-density lipoprotein cholesterol (LDL-C) in the blood. The goals of this study are to learn about the safety of enlicitide and if children tolerate it, what happens to enlicitide in a child's body over time, and if enlicitide works to lower cholesterol levels in children more than a placebo.
Eligibility
Inclusion Criteria4
- Has possible or definite diagnosis of HeFH based on a locally accepted diagnostic algorithm or diagnosis by genetic testing results
- Has a fasted LDL-C value (evaluated by the central laboratory) that is ≥130 mg/dL
- Is receiving either an optimized daily dose of statin (± nonstatin LLT); or a nonstatin LLT with documented intolerance to at least 2 different statins or refusal of statin therapy by the participant or legally acceptable representative
- Is on a stable dose of all background LLTs for at least 30 days prior to screening, with no medication or dose changes planned during participation in Part A or Part B
Exclusion Criteria4
- Has a history of homozygous FH based on genetic or clinical criteria, or history of known compound heterozygous FH, or double heterozygous FH
- Has a history of nephrotic syndrome
- Has any clinically significant malabsorption condition based on principal investigator assessment
- Was previously treated/is being treated with certain other cholesterol lowering medications, including proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors without adequate washout
