Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPart A: Maximum Observed Serum Concentration (Cmax) of EvinacumabAt day 12Cmax was obtained directly from the plasma concentration versus time curve.
PrimaryPart A: Area Under the Serum Concentration-Time Curve From Time Zero to the Time of the Last Measurable Concentration (AUClast) of EvinacumabUp to Week 12AUClast was defined as area under the serum concentration time-curve from zero to the last measured concentration.
PrimaryPart A: Terminal Half-Life (t1/2) of EvinacumabUp to week 12T1/2 was defined as the time required for the plasma concentration of drug to decrease 50 percent in the final stage of its elimination.
PrimaryPart B: Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24Baseline to Week 24Percent 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.
SecondaryPart 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
Any untoward medical occurrence in a participant who received investigational medicinal product (IMP) was considered an AE without regard to possibility of causal relationship with this treatment. A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. TEAE was defined as AE starting/worsening after first intake of study drug. TEAE included participants with both serious and non-serious AEs. 1 participant experienced an AE during part B that was recorded after Part B database lock. This was not reflected in the reported endpoint number of participants of 10.
SecondaryPart B: Percent Change in Apolipoprotein B (Apo B) From Baseline to Week 24Baseline to Week 24Percent change in Apo B from baseline to Week 24 was reported.
SecondaryPart B: Percent Change in Non-High-Density Lipoprotein Cholesterol (Non-HDL-C) From Baseline to Week 24Baseline to Week 24Percent change in Non-HDL-C from baseline to Week 24 was reported.
SecondaryPart B: Percent Change in Total Cholesterol (TC) From Baseline to Week 24Baseline to Week 24Percent change in TC from baseline to Week 24 was reported.
SecondaryPart B: Percentage of Participants With ≥50 Percent (%) Reduction in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) at Week 24Week 24Percentage of participants who achieved reduction in calculated LDL-C ≥ 50% at Week 24 was reported.
SecondaryPart B: Percent Change in Calculated Low-Density Lipoprotein Cholesterol (LDL-C) From Baseline to Week 24 in Participants Who Have Negative/Negative and Null/Null MutationsBaseline to Week 24
Participants with HoFH was classified based on the phenotype of the Low-density lipoprotein receptor (LDLR) mutation(s), ranging from defective mutations (where the LDLR retains some LDL-binding functionality) to null or negative mutations where no functioning LDLR was expressed. Participants who have LDLR activity \<15% are considered null and participants whose LDLR activity was impaired but \>15% are LDLR defective. Percent change in calculated LDL-C from baseline to Week 24 in participants who have negative/negative and null/null mutations was reported.
