Outcomes

Primary Outcome Measures

Percent Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at Week 12: Intent-to-Treat (ITT) Analysis
Adjusted least square (LS) means and standard errors were obtained from the mixed model analysis with repeated measures (MMRM) to account for missing data using all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis).

Secondary Outcome Measures

Percent Change From Baseline in Low-Density Lipoprotein Cholesterol at Week 12: On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline on-treatment data from Week 4 to Week 48 (on-treatment Analysis).
Percent Change From Baseline in Low-Density Lipoprotein Cholesterol at Weeks 24 and 48: ITT Analysis/On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Percent Change From Baseline in Apolipoprotein (Apo) B at Weeks 12, 24 and 48: ITT Analysis/On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Percent Change From Baseline in Non-High Density Lipoprotein Cholesterol (Non-HDL-C) at Weeks 12, 24 and 48 - ITT Analysis/On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.

Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Percent Change From Baseline in Apolipoprotein A1 (Apo A1) at Weeks 12, 24 and 48: ITT Analysis/On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline data from Week 4 to 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Percentage of Participants Reporting >=15 Percent (%) Reduction in LDL-C Level at Weeks 12, 24 and 48: ITT Analysis/On-treatment Analysis
Adjusted Percentage were obtained from a multiple imputation approach for handling of missing data including all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Absolute Change From Baseline in LDL-C Level at Weeks 12, 24 and 48: ITT Analysis/On-treatment Analysis
Adjusted LS means and standard errors were obtained from the MMRM model to account for missing data using all available post-baseline data from Week 4 to Week 48 regardless of status on- or off-treatment used in the model (ITT analysis). Although separate analyses of all available data (ITT analysis) and only data collected within a defined time window (On-treatment analysis) were planned, if all values used in the ITT approach were within the on-treatment time window, the on-treatment analysis would be identical to the ITT analysis, thus the results would be identical and a single outcome measure presenting the results for both types of analysis would be provided.
Number of Participants With Tanner Staging at Baseline, Weeks 12, 24 and 48
Tanner stage defines physical measurements of development in children and adolescent based on external primary and secondary sex characteristics. Participants were evaluated for pubic hair distribution, breast development (only females) and genital development (only males), and classified in 3 categories as: Prepubescent (defined as a person just before start of the development of adult sexual characteristics), Pubescent (defined as a person at or approaching the age of puberty), Postpubescent (sexually mature or a person who has completed puberty).
