An Study to Evaluate Rosuvastatin in Children and Adolescents With Familial Hypercholesterolaemia

An Efficacy and 2-Year Safety Study of Open-label Rosuvastatin in Children and Adolescents (Aged From 6 to Less Than 18 Years) With Familial Hypercholesterolaemia

This study is being carried out to see if the study medication, rosuvastatin, is effective in treating familial hypercholesterolaemia in children and adolescents, and to determine the long term (over 2 years) safety, tolerability and efficacy of the study medication in these patients. This study will also measure levels of drug in the blood and see how well it is tolerated. This is known as pharmacokinetic (PK) analysis. At baseline only a small number of patients will participate in a single dose PK phase over 24 hours. In order to see if this medication works, a control group of healthy siblings will help the researchers to compare certain results.

Negative values represent a decrease and positive values represent an increase. In total, 198 patients were treated. One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Tanner stages (I-V) was used to characterize physical development in children and adolescent. The stages was based on external primary and secondary sex characteristics, such as the size of the breasts, genitalia, and development of pubic hair. Tanner stage is considered going up when the organs grow bigger.

Serial plasma samples were taken at baseline (Week 0) at: 0.5 hours pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 9, 12 hours and on Day 1 at 24 hours after the single 10 mg dosing

One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Percent Change From Baseline in HDL-C, TC, TG, Non-HDL-C, LDL-C/HDL-C, TC/HDL-C, Non HDL C/HDL-C, ApoB, ApoA-1, and ApoB/ApoA-1

One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Number of participants with Various Categories of AE's. One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Total duration of exposure was calculated as [last dose date of rosuva - first dose date of rosuva + 1 day]. One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Overall adherence rate was calculated as the weighted mean of adherence rates of all consecutive visits after baseline, in which the adherence rate between 2 consecutive visits was a percentage of the number of rosuvastatin taken divided by duration of exposure. One patient received 1 dose of study drug but was not included in the efficacy and safety analyses due to a lack of follow-up data.

Inclusion Criteria: children and adolescents (aged 6 to less than 18 years) with Familial Hypercholesterolaemia Patients aged between 6 and less than 10 years of age must not be taking a statin medicine Exclusion Criteria: History of muscle or sensitivity reactions to any statin medicines Current active liver disease or dysfunction (except a confirmed diagnosis of Gilbert's disease)
