A Randomized, Double-blind, Placebo-Controlled, Dose-Ranging Phase 2 Study of ISIS 681257 (AKCEA-APO(a)-LRx) Administered Subcutaneously to Patients With Hyperlipoproteinemia(a) and Established Cardiovascular Disease (CVD)

Number of Participants With TEAEs Leading to Study Discontinuation

时间窗: Up to 16 weeks post treatment period (up to approximately 1.3 years)

An AE was defined as any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE was considered related to the investigational drug product. TEAE was defined as any AE with onset after the first administration of study medication through the end of the study, or any event that was present at baseline but worsened in intensity or was subsequently considered drug-related by the Investigator through the end of the study.

Percent Change From Baseline in Fasting Lipoprotein A [Lp(a)] at the Primary Analysis Time Point

时间窗: Baseline and Month 6 (Week 25 for Cohorts A, B and C and Week 27 for Cohorts D and E)

An ANCOVA model was performed on the log ratio of Lp(a) value at the Primary Analysis Time Point to Lp(a) value at Baseline. The estimate of the log ratio was converted back to the original scale and percent change was calculated using formula: = (ratio of Lp(a) value at the Primary Analysis Time Point to Lp(a) value at Baseline - 1) × 100.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)

时间窗: Up to 16 weeks post treatment period (up to approximately 1.3 years)

An adverse event (AE) was defined as any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE was considered related to the investigational drug product. TEAEs was defined as any AE with onset after the first administration of study medication through the end of the study, or any event that was present at baseline but worsened in intensity or was subsequently considered drug-related by the Investigator through the end of the study.

Number of Participants With TEAEs by Maximum Severity

时间窗: Up to 16 weeks post treatment period (up to approximately 1.3 years)

An AE was defined as any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE was considered related to the investigational drug product. TEAEs was defined as any AE with onset after the first administration of study medication through the end of the study, or any event that was present at baseline but worsened in intensity or was subsequently considered drug-related by the Investigator through the end of the study. The severity of TEAEs was assessed based on the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. TEAEs were graded on a 5-point scale where 1 = Mild, 2 = Moderate, 3 = Severe, 4 = Potentially life-threatening and 5 = Death.
