A Study of the Efficacy and Safety of Enclitide Chloride (MK-0616 Oral PCSK9 Inhibitor) in Adults With Hypercholesterolemia (MK-0616-008)

Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at Week 8

Timeframe: Baseline and up to Week 8

Blood samples were collected at baseline and after 8 weeks of treatment to assess mean percent change in LDL-C. Based on a constrained longitudinal analysis (cLDA) model including terms for treatment, time, baseline statin intensity, baseline renal function, and the interaction of treatment by time. The percent change from baseline in LDL-C at week 8 was reported.

Percentage of Participants Who Experienced One or More Adverse Events (AEs)

Timeframe: Up to approximately 17 Weeks

An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who experienced at least one AE was reported.

Percentage of Participants Who Discontinued Study Intervention Due to AEs

Timeframe: Up to approximately 9 Weeks

An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who discontinued study intervention due to AEs was reported.

Percent Change From Baseline in Apolipoprotein B (ApoB) at Week 8

Timeframe: Baseline and up to Week 8

Blood samples were collected at baseline and after 8 weeks of treatment to assess mean percent change in ApoB. The least square mean and 95% CI were obtained from fitting a cLDA model including terms for treatment, time, baseline statin intensity, baseline renal function, and the interaction of treatment by time. The percent change from baseline in ApoB at week 8 was reported.

Percent Change From Baseline in Non-High-density Lipoprotein Cholesterol (Non-HDL-C) at Week 8

Timeframe: Baseline and up to Week 8

Blood samples were collected at baseline and after 8 weeks of treatment to assess mean percent change in non-HDL-C. The least square mean and 95% CI were obtained from fitting a cLDA model including terms for treatment, time, baseline statin intensity, baseline renal function, and the interaction of treatment by time. The percent change from baseline in non-HDL-C at week 8 was reported.

Percentage of Participants With LDL-C Value at Goal at Week 8

Timeframe: Week 8

LDL-C goal was defined as: LDL-C \<70 mg/dL (\<1.81 mmol/L) in participants with clinical atherosclerotic cardiovascular disease (ASCVD), LDL-C \<100 mg/dL (\<2.59 mmol/L) in participants with an ASCVD risk-equivalent and/or a 10-year risk of having an ASCVD event that is ≥7.5%, OR LDL-C \<130 mg/dL (\<3.37mmol/L) in participants with a 10-year risk of having an ASCVD event that is ≥5.0% and \<7.5%. The percentage of participants with LDL-C value at goal at week 8 were reported.
