结局指标
主要结局
Percentage of Participants With Any Serious Adverse Event - Treatment Phase
时间窗: Up to 52 weeks
A serious adverse experience (SAE) was any adverse event that occurred at any dose that resulted in death or was life threatening, resulted in a persistent or significant disability/incapacity, resulted in or prolonged an existing inpatient hospitalization, or was a congenital anomaly/birth defect. The percentage of participants with any serious adverse event during the treatment phase is presented.
Percentage of Participants With Potassium Levels < Lower Limit of Normal (LLN)
时间窗: Up to 52 weeks
Participants had potassium levels assessed throughout the 52-week treatment period. The percentage of participants who had any potassium level that was \< the LLN of 3.5 mEq/L during the treatment phase is presented.
Percentage of Participants With CK Level >=10 x ULN With Muscle Spasms
时间窗: Up to 52 weeks
Participants had CK levels assessed throughout the 52-week treatment period. The percentage of participants who had any CK level that was \>=10 x ULN and had associated muscle spasms during the treatment phase is presented.
Percent Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C) - Treatment Phase
时间窗: Baseline and Week 52
LDL-C levels were measured at baseline and week 52 (or at discontinuation) using a beta quantification method. The Treatment Phase was the period from the date of the participant's first dose of study treatment (randomization visit, Visit 3) to the participant's last visit on treatment (discontinuation visit or Visit 8 \[Week 52\]).
Percentage of Participants With Changes in Diastolic Blood Pressure (DBP) >= 10 mm Hg
时间窗: Up to 52 weeks
Participants had DBP assessed at baseline and throughout the 52-week treatment period. The percentage of participants who had a DBP reading that was \>= 10 mm Hg higher than their baseline DBP for any assessment performed during the treatment phase is presented.
Percentage of Participants With Chloride Levels > ULN
时间窗: Up to 52 weeks
Participants had chloride levels assessed throughout the 52-week treatment period. The percentage of participants who had any chloride level that was \> the ULN of 110 mEq/L during the treatment phase is presented.
Percentage of Participants Adjudicated Cardiovascular (CV) SAE
时间窗: Up to 52 weeks
An AE or suspected adverse reaction was considered an SAE if it resulted in any of the following outcomes: death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or a congenital anomaly/birth defect. All events were adjudicated by an expert committee independent of the Sponsor. The percentage of participants that experienced adjudicated SAEs of CV death, non-fatal stroke, non-fatal myocardial infarction, or unstable angina during the treatment phase is presented.
Percentage of Participants Who Died From Any Cause - Treatment Phase
时间窗: Up to 52 weeks
The percentage of participants who died from any cause during the treatment phase is presented. All deaths were adjudicated by an expert committee independent of the Sponsor.
Percentage of Participants With Changes in Systolic Blood Pressure (SBP) >= 10 mm Hg

The percentage of participants with any adverse event during the treatment phase is presented.
Percentage of Participants With Any Treatment-Related Adverse Event - Treatment Phase

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study treatment, whether or not considered related to the use of the treatment. Any worsening of a preexisting condition which was temporally associated with the use of the study treatment was also an AE. AEs reported by the investigator as definitely, probably or possibly related to study treatment were considered treatment-related. The percentage of participants with any treatment-related adverse event during the treatment phase is presented.
Percentage of Participants Discontinuing Study Treatment Due to an Adverse Event - Treatment Phase
时间窗: Up to 52 weeks
An adverse event (AE) was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study treatment, whether or not considered related to the use of the drug. Any worsening of a preexisting condition which was temporally associated with the use of the study drug was also an AE. The percentage of participants who discontinued study treatment due to an AE during the treatment phase is presented.
