Is this trial a fit for you?

Likely a good fit

Children and adolescents with a definite or possible diagnosis of HeFH, a fasting LDL-C ≥130 mg/dL, and who are on a stable lipid-lowering regimen or are statin-intolerant/refuse statins.

Probably not a fit

Patients with homozygous, compound, or double heterozygous FH, active nephrotic syndrome, significant malabsorption, or other listed exclusion conditions are unlikely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, placebo-controlled Phase 2/3 interventional study gives children and adolescents with HeFH either oral enlicitide decanoate or placebo while monitoring safety, tolerability, and LDL-C changes. Participants must have a fasting LDL-C ≥130 mg/dL and be on stable background lipid-lowering therapy or have documented statin intolerance or refusal. The study includes pharmacokinetic sampling to see how the drug behaves in a child's body and regular lab and clinical assessments to track side effects. The primary clinical aim is to compare LDL-C lowering versus placebo while characterizing safety in this pediatric population.

Why it matters

Potential benefit: If successful, the drug could provide an easy-to-take oral option that lowers LDL cholesterol in children and may reduce long-term cardiovascular risk.

How similar studies have gone: Injectable PCSK9 monoclonal antibodies have successfully lowered LDL-C in adults and some pediatric reports, but oral PCSK9 inhibitors like enlicitide are a newer approach with limited prior pediatric data.
