Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the efficacy of rosuvastatin in paediatric patients with FH. To establish long-term safety, tolerability and efficacy of rosuvastatin in paediatric patients with FH. To characterise the PK profile of rosuvastatin in paediatric patients with FH, aged from 6 to less tha Tanner Stage II, with familial hypercholesterolaemia.;Secondary Objective: To assess cIMT by sonography at baseline and every year in patients and in healthy siblings. To assess growth and maturation in children or adolescents with FH who are receiving long-term rosuvastatin treatment. Assessment of adherence to rosuvastatin during a 2-year period of treatment. To assess the feasibility and acceptability of the current marketed tablet formulation of rosuvastatin for use in children. ;Primary end point(s): The primary efficacy parameter is the percentage reduction in LDL-C in patients from baseline to 3 months, 12 months and 24 months of treatment with 5 mg, 10 mg or 20 mg rosuvastatin. To establish the long-term safety, tolerability and efficacy of rosuvastatin in psediatric patients with FH. The assessment of growth by assessment of height (including linear growth [cm and standard deviationscore]) and secondary characteristics of sexual maturation by Tanner staging at baseline, 12 months and 24 months. Single dose pharmacokinetics of rosuvastatin: Cmax, tmax, and AUC(0-24). Population pharmacokinetics of rosuvastatin: CL/F and AUC(0-24) at steady state.;Timepoint(s) of evaluation of this end point: baseline (week 0), 12 months, and 24 months. | — |
