Study Endpoints
Primary Endpoints
Part A: Maximum Observed Serum Concentration (Cmax) of Evinacumab
At day 12

Cmax was obtained directly from the plasma concentration versus time curve.

Part A: Area Under the Serum Concentration-Time Curve From Time Zero to the Time of the Last Measurable Concentration (AUClast) of Evinacumab
Up to Week 12

AUClast was defined as area under the serum concentration time-curve from zero to the last measured concentration.

Part A: Terminal Half-Life (t1/2) of Evinacumab
Up to week 12

T1/2 was defined as the time required for the plasma concentration of drug to decrease 50 percent in the final stage of its elimination.

Part B: Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24
Baseline to Week 24

Percent change was calculated as 100 multiplied by (calculated LDL-C value at Week 24 minus calculated LDL-C value at baseline) divided by calculated LDL-C value at baseline.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) Up to Week 216
Up to 216 weeks

The safety analysis set (SAF) included all participants who were enrolled and received at least 1 dose or part of a dose of open-label study treatment.

Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24 (Intent-to-Treat [ITT] Estimand)
Week 24

Percent change was calculated as 100x(calculated LDL-C value at Week 24 - calculated LDL-C value at baseline)/calculated LDL-C value at baseline. The baseline LDL-C value was the last calculated LDL-C value obtained before the first dose of double-blind-study drug. The calculated LDL-C at week 24 was the LDL-C value obtained within the week 24 efficacy analysis window, regardless of adherence to treatment and subsequent therapies (intent-to-treat \[ITT\] estimand). The ITT population included all randomized participants who received at least one dose or part of a dose of double-blind study drug. Participants in the ITT population were analyzed according to the treatment group allocated by randomization (i.e., as randomized participant group).

Secondary Endpoints
Part A and Part B: Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Part A: up to Week 24; Part B: up to Week 48
Part B: Percent Change in Apolipoprotein B (Apo B) From Baseline to Week 24
Baseline to Week 24
Part B: Percent Change in Non-High-Density Lipoprotein Cholesterol (Non-HDL-C) From Baseline to Week 24
Baseline to Week 24
