The purpose of this study was to assess the effectiveness of an "inclisiran first" implementation strategy (addition of inclisiran to maximally tolerated statin therapy immediately upon failure to achieve acceptable LDL-C with maximally tolerated statin therapy alone) compared to usual care in an atherosclerotic cardiovascular disease (ASCVD) population.
The study design was a randomized, two-arm, parallel-group, open-label, multicenter, clinical trial comparing an "inclisiran first" implementation strategy to usual care (1:1 randomization) with established ASCVD and elevated LDL-C (or non-HDL-C) despite treatment with maximally tolerated statin therapy. Eligible patients had established ASCVD and elevated LDL-C levels ≥ 70 mg/dL (or non-HDL-C ≥ 100 mg/dL) despite treatment with maximally tolerated statin therapy. In the "inclisiran first" implementation strategy group post-randomization, addition of other non-statin LDL-C lowering therapies (e.g., ezetimibe or bempedoic acid, excluding PCSK9 inhibiting monoclonal antibodies) were allowed to reach acceptable LDL-C levels. In the "inclisiran first" implementation strategy group, inclisiran was administered initially at randomization, 90 days later, and six months, thereafter.

Percent Change From Baseline in LDL-C
Percent change from baseline in Low-Density Lipoprotein Cholesterol (LDL-C) of an "inclisiran first" implementation strategy compared to usual care at Day 330.
Time frame: Baseline, Day 330
Percentage of Participants Who Discontinued Statin Therapy
Percentage of patients who discontinued statin therapy ≥ 30 days before the end-of-study visit of an "inclisiran first" implementation strategy compared to usual care, for patients in the FAS excluding those with a medical history of statin intolerance.
Time frame: Day 330
Absolute Change From Baseline in LDL-C
Absolute change in Low-Density Lipoprotein Cholesterol (LDL-C) of an "inclisiran first" implementation strategy compared to usual care at Day 330
Time frame: Baseline, Day 330
Average Percent Change From Baseline in LDL-C Levels Across Visits
Average percent change in Low-Density Lipoprotein Cholesterol (LDL-C) of an "inclisiran first" implementation strategy compared to usual care across visits. Calculated by averaging the observed post-baseline values (percent change) for each participant across analysis visits.
Time frame: Up to 330 Days
Average Absolute Change From Baseline in LDL-C Levels Across Visits
Average absolute change in Low-Density Lipoprotein Cholesterol (LDL-C) of an "inclisiran first" implementation strategy compared to usual care across visits. Calculated by averaging the observed post-baseline values (absolute change) for each participant across analysis visits.
Time frame: Up to 330 days
Percentage of Participants Achieving ≥ 50% Reduction From Baseline in LDL-C
Percentage of patients achieving a ≥ 50% reduction from baseline in Low-Density Lipoprotein Cholesterol (LDL-C) levels of an "inclisiran first" implementation strategy compared to usual care at Day 330. Missing data is imputed using "non-responder" (i.e., "negative" outcome) imputation.
Time frame: Baseline, Day 330
Percentage of Participants Achieving LDL-C < 100 mg/dL.
Percentage of participants achieving Low-Density Lipoprotein Cholesterol (LDL-C) \< 100 mg/dL (among the subset of participants with LDL-C \>=100 mg/dL at baseline) of an "inclisiran first" implementation strategy compared to usual care at Day 330. Missing data is imputed using "non-responder" (i.e., "negative" outcome) imputation.
Time frame: Day 330
Percentage of Participants Achieving LDL-C < 70 mg/dL
Percentage of participants achieving Low-Density Lipoprotein Cholesterol (LDL-C) \< 70 mg/dL of an "inclisiran first" implementation strategy compared to usual care at Day 330. Missing data is imputed using "non-responder" (i.e., "negative" outcome) imputation.
Time frame: Day 330
Percentage of Participants Achieving LDL-C < 55 mg/dL
Percentage of participants achieving Low-Density Lipoprotein Cholesterol (LDL-C) \< 55 mg/dL of an "inclisiran first" implementation strategy compared to usual care at Day 330. Missing data is imputed using "non-responder" (i.e., "negative" outcome) imputation.
Time frame: Day 330
Percent Change in Lipids and Other Lipoproteins From Baseline
Percent change in plasma lipids, lipoproteins and triglycerides in participants receiving an "inclisiran first" implementation strategy compared to usual care at Day 330
Time frame: Baseline, Day 330
Absolute Change in Lipids and Other Lipoproteins From Baseline
Absolute change in plasma lipids, lipoproteins and triglycerides in participants receiving an "inclisiran first" implementation strategy compared to usual care at Day 330
Time frame: Baseline, Day 330
Percentage of Participants by Intensity of Lipid Lowering Therapy
Percentage of participants with decrease in dose, no change in dose or increase in dose to assess changes in background lipid-lowering therapy in participants receiving an "inclisiran first" implementation strategy compared to usual care at Day 330
Time frame: Baseline, Day 330
Proportion of Days Covered by Medication
Proportion of days covered refers to the total number of days on either statin, ezetimibe, bempedoic acid or PCSK9 inhibiting monoclonal antibody therapies taken during the study divided by total number of study days, calculated for each participant; If a participant did not take any of the four medications then the total number of days will be assumed to be zero.
Time frame: Up to 330 Days
LDL-C Measures of Variability - Standard Deviation
Visit-to-visit LDL-C variability from Day 90 until Day 330 of an "inclisiran first" implementation strategy compared to usual care. It was assessed using two measures of variability: standard deviation and coefficient of variation.
Time frame: Day 90, Day 180, Day 270 and Day 330
