abstract

  • BACKGROUND: Statin therapy is recommended for children with familial hypercholesterolemia (FH), but most children do not reach treatment targets. OBJECTIVE: Here we present the design and results at baseline of the ongoing CHARON study, to evaluate the safety and efficacy of rosuvastatin. METHODS: This study comprises an international 2-year open label, titration-to-goal study in 198 children with heterozygous FH aged 6 to 18 years, with rosuvastatin in a maximum dose of 10 mg (<10 years of age) or 20 mg (older children). In addition, 64 unaffected siblings were enrolled as controls. The primary efficacy outcome is the change from baseline in low-density lipoprotein cholesterol, and the secondary outcome is the change in carotid intima-media thickness (c-IMT) in patients with FH compared with their siblings. The primary safety outcomes are growth and sexual maturation; secondary outcomes are the change in other lipoprotein levels and the incidence of adverse events, discontinuation rates, and abnormal laboratory values. RESULTS: At baseline, mean age of patients with FH was 12.1 ± 3.3 years, 44% were boys, and mean low-density lipoprotein cholesterol levels were 6.1 ± 1.3 mmol/L (235.9 ± 48.7 mg/dL). Mean c-IMT was 0.399 mm (95% CI, 0.392-0.406 mm) in children with FH versus 0.377 (95% CI, 0.366-0.388 mm) in unaffected siblings (P = .001). CONCLUSIONS: At baseline, as expected according to on previous observations, children with FH proved to have a greater c-IMT than their healthy siblings. These differences had already occurred at a very young age, which emphasizes the importance of considering early statin initiation in this high-risk population.
