General information about the trial
|
|||
Main objective of the trial |
To assess the 12-week efficacy of bempedoic acid 180 mg/day versus placebo in decreasing low-density lipoprotein cholesterol (LDL-C) when added to ezetimibe therapy in participants with elevated LDL-C.
|
||
Protection of trial subjects |
The trial was designed, conducted, and monitored in accordance with sponsor procedures, which comply with the ethical principles of Good Clinical Practice (GCP) as required by the major regulatory authorities, and in accordance with the Declaration of Helsinki.
|
||
Background therapy |
All participants received study supplied ezetimibe 10 mg/day as background therapy throughout the study. Participants on low or very low-dose statin at screening could continue statin therapy throughout the study provided that the dose was stable (≥4 weeks) and well tolerated. Low dose statin therapy was defined as an average daily dose of rosuvastatin 5 mg, atorvastatin 10 mg, simvastatin 10 mg, lovastatin 20 mg, pravastatin 40 mg, fluvastatin 40 mg, or pitavastatin 2 mg. Very low-dose statin therapy was defined as an average daily dose of rosuvastatin <5 mg, atorvastatin <10 mg, simvastatin <10 mg, lovastatin <20 mg, pravastatin <40 mg, fluvastatin <40 mg, or pitavastatin <2 mg. Participants were instructed to continue taking their lipid-modifying therapy (LMT) throughout the study. PCSK9 inhibitors were not allowed during the study period. Other LMTs were to remain stable for at least 4 weeks prior to screening; fibrates (with the exception of gemfibrozil which was exclusionary in participants aking a statin) were to remain stable for at least 6 weeks prior to screening. | ||

Recruitment
|
||||||||||||||||||||||||||||
Recruitment details |
Out of the 269 participants who were randomized to the double-blind treatment period, 181 participants were randomized to bempedoic acid and 88 participants to placebo. One participant in the placebo group was randomized but never started treatment. | |||||||||||||||||||||||||||
Pre-assignment
|
||||||||||||||||||||||||||||
Screening details |
The study consisted of an approximate 1-week screening period, a 4-week single-blind placebo and ezetimibe run-in period, and a 12-week double-blind treatment period. | |||||||||||||||||||||||||||

Blinding implementation details |
The Sponsor, all clinical site personnel (investigator, pharmacist, etc.), and other vendor personnel were blinded to the treatment group for each participant. Participants were also blinded to the treatment they received. Bempedoic acid and placebo had identical physical appearance and packaging. Blinding of treatment was maintained for all participants unless, in the opinion of the investigator, the safety of the participant was at risk.

End point description |
Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analyzed for LDL-C. Baseline was defined as the mean of the LDL-C values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: ([LDL-C value at Week 12 minus Baseline value] divided by [Baseline Value]) multiplied by 100. Bempedoic Acid = BA.

Difference [BA - placebo] in LS mean | |||||||||||||||
Statistical analysis description |
The analysis compared the percent change from baseline between treatment groups using a two-sided test at the 0.05 level of significance and a confidence interval of 95%. Least square (LS) mean, 95% CI, and P-value was based on an ANCOVA model with percent change from baseline as the dependent variable, treatment as a fixed effects and baseline as a covariate. The missing parameter at Week 12 was imputed using a multiple imputation method taking into account adherence to treatment.

Percent Change From Baseline to Weeks 4 and 8 in LDL-C | ||||||||||||||||||
End point description |
Blood samples were drawn after a minimum 10-hour fast (water was allowed) at pre-specified intervals. Samples were collected and analyzed for LDL-C. Baseline was defined as the mean of the LDL-C values from the last two non-missing values on or prior to Day 1. Percent change from baseline was calculated as: [(LDL-C value at Week 4 or 8 minus Baseline value) divided by (Baseline Value)] multiplied by 100.

Statistical analysis description |
The analysis compared the percent change from baseline between treatment groups using a two-sided test at the 0.05 level of significance and a confidence interval of 95%. LS mean, 95% CI, and P-value was based on an ANCOVA model with percent change from baseline as the dependent variable, treatment as a fixed effects and baseline as a covariate. Observed data was used for the analysis, no imputation for the missing data was performed.

Amendment |

10 Feb 2017 |
Protocol Amendment 2, dated 10 February 2017, included the following key changes:
• Changed protocol title to more accurately reflect the study population based on guidance from the Food and Drug Administration (FDA)
• Updated the bempedoic acid mechanism of action
• Revised various inclusion criterion and exclusion criterion
• Excluded use of cholesteryl ester transfer protein inhibitor (CETP) inhibitors
• Changed exclusion time period for mipomersen to 6 months
• Removed the allowance to rescreen if low-density lipoprotein cholesterol (LDL-C) criteria at screening visit 1 (S1) were not met
• Extended screening an additional 4 weeks if needed to adjust background therapy
• Removed collection of pharmacokinetic (PK) at Day 0; specified collection of PK samples prior to Investigational medicinal product (IMP) dosing
• Added requirement to Visit S3 (Week -1) that LDL-C ≥70 milligrams per deciliter (mg/dL)
• Added chemistry panel and creatine kinase (CK) to Visit S3 (Week -1) given inclusion of ezetimibe naive participants
• Removed optional genetic sampling
• Removed instructions to reserve samples
• Corrected windowing of allowable and prohibited medications to be consistent between entry criteria and protocol body
• Removed lipids other than LDL-C as a specified tertiary endpoint
• Removed manufacturing contact details (provided in pharmacy manual)
• Added text on the administration of study-supplied ezetimibe, including assessment of relationship of adverse events (AEs) to both IMP and ezetimibe
• Changed monitoring of CK for asymptomatic participants per FDA request
• Revised safety endpoints
• Revised statistical sections to clarify level of significance, standard deviation, methods for imputation of missing data, and application of analysis of covariance (ANCOVA) model for primary and secondary endpoints
• Made administrative changes made throughout protocol where required to correct inconsistencies, add clarification, or correct errors |
