Open Label Phase 3b Study to Evaluate the Long-Term Efficacy and Safety of Lerodalcibep in Children and Adolescents, 6 to 17 Years of Age, With Heterozygous Familial Hypercholesterolemia on Stable Diet and Oral Lipid-Lowering Therapy

The goal is to assess the long term efficacy (LDL cholesterol reduction) and safety over 3 years of lerodalcibep (Lerochol) SC 300 mg QM administered by auto-injector (AI)/pre-filled pen (PFP) in male and female pediatric patients 6 to 17 years of age, with inherited high cholesterol (HeFH) on a stable diet and maximally tolerated oral LDL C lowering drug therapy such as statins who completed the 24 week placebo controlled base trial.

The main question\[s\] it aims to answer are:

How effective is Lerochol in maintaining LDL cholesterol reductions over years? How well is it tolerated and are there any safety concerns?

Participants will visit the clinic every month for 3 months and then home dosed with clinic visits every 3 months. They will undergo periodic physical exams, height and weight measurements, answer questions, have blood drawn from a vein in their arm, have blood pressure measurements, EKC heart tests, and receive monthly injections lasting about 5 seconds in their arms or abdomen with an autoinjector.
