| Percentage of Participants With Adverse Events (AEs) Related to Type 1 and 3 Hypersensitivity Reactions and Injection Site Reactions | Type 1 hypersensitivity or allergic reactions were possible in response to any injected protein and included shortness of breath, urticaria, anaphylaxis and angioedema. Type 3 hypersensitivity reactions were similar to Type 1 hypersensitivity reactions but were likely to be delayed from the time of injection and included symptoms such as rash, urticaria, polyarthritis, myalgia's, polysynovitis, fever and if severe then included glomerulonephritis. Injection site reactions included injection site bruising, discolouration, erythema, haematoma, haemorrhage, nodule, induration, inflammation, mass, pain, paraesthesia, pruritus, swelling, vesicles, warmth, scab and rash. Participants with type 1 or type 3 hypersensitivity reactions and participants with injection site reactions were reported in this outcome measure. | Baseline up to end of study (up to 110 weeks) | 
| Percentage of Participants With Anti-Drug Antibodies (ADA) and Neutralizing Antibodies (nAb): Treatment Period | Percentage of participants with at least 1 positive ADA titer or 1 positive nAb titer were reported. ADA titer >=6.23 (log 2) unit was considered to be ADA positive and nAb titer >=1.58 (log 2) unit was considered to be nAb positive. | Baseline up to Week 58 | 
| Number of Participants Who Changed Concomitant Medication During Extension Period | In this outcome measure, total number of participants who changed their lipid-lowering medications or added a monoclonal antibody medication during the extension period were reported. | Week 58 follow-up to Week 110 | 
| Percent Change From Baseline in Fasting Low Density Lipoprotein Cholesterol (LDL-C) at Week 58 (Follow up), 71, 84, 97 and 110: Extension Period |  | Baseline, Week 58 (follow up), 71, 84, 97, 110 | 
| Percentage of Participants With Anti-Drug Antibodies (ADA) and Neutralizing Antibodies (nAb): Extension Period | Percentage of participants with at least 1 positive ADA titer or 1 positive nAb titer were reported. ADA titer >=6.23 log2 unit was considered to be ADA positive and nAb titer >=1.58 log2 unit was considered to be nAb positive. | Week 58 (follow-up), Week 71, Week 84, Week 97, Week 110 |
