Among patients with diabetes at baseline, mean hemoglobin A1c (HbA1c) levels decreased from baseline to week 12 by 0.08 percentage point in the bempedoic acid group and increased by 0.13 percentage point in the placebo group.  JD, Cziraky By continuing to use our site, or clicking "Continue," you are agreeing to our, 2020 American Medical Association. To what extent does bempedoic acid lower low-density lipoprotein cholesterol (LDL-C) levels in patients at high cardiovascular risk who have ongoing hypercholesterolemia, despite the use of maximally tolerated lipid-lowering therapy? Then, aside from the poorly tolerated and modestly efficacious bile acid sequestrants, the only other options are the new proprotein convertase subtilisin/kexin type 9 (PCSK-9) inhibitors. Significant reductions with bempedoic acid vs placebo were observed at week 12 for non–high-density lipoprotein cholesterol (–10.8% vs 2.3%; difference, –13.0% [95% CI, –16.3% to –9.8%]; P < .001), total cholesterol (–9.9% vs 1.3%; difference, –11.2% [95% CI, –13.6% to –8.8%]; P < .001), apolipoprotein B (–9.3% vs 3.7%; difference, –13.0% [95% CI, –16.1% to –9.9%]; P < .001), and high-sensitivity C-reactive protein (median, –18.7% vs –9.4%; difference, –8.7% [asymptotic confidence limits, –17.2% to –0.4%]; P = .04). The primary end point was percent change from baseline in LDL-C level at week 12.

Goldberg AC, Leiter LA, Stroes ESG, et al. Design, Setting, and Participants  This calculation was based on a 2-sided t test at the 5% level of significance, with a standard deviation of 15%. No imputation was performed for missing data in sensitivity, subgroup, or post hoc analyses.  CM, Banach Patients were asked to self-identify their race and ethnicity according to protocol-defined fixed categories to evaluate potential differences in response to therapy.

What is exciting is the potential for its use in combination with generic ezetimibe. Bempedoic Acid for Lowering LDL Cholesterol, Michael C. Honigberg, MD, MPP; Pradeep Natarajan, MD, MMSc, Measuring vs Estimating LDL-C Levels in a Clinical Trial of Bempedoic Acid, Hua-Guo Xu, MD, PhD; Shiyang Pan, MD, PhD, Measuring vs Estimating LDL-C Levels in a Clinical Trial of Bempedoic Acid—Reply, Anne Carol Goldberg, MD; Jeffrey C. Hanselman, MS; P. Barton Duell, MD, Cardiovascular Corner—Stable Coronary Artery Disease, An LDL “Vaccine,” and Anti-inflammatories. Changes in HbA1c levels across populations with diabetes and with impaired fasting glucose showed improvement or less worsening of glycemic control at week 12 (eTable 6 in Supplement 3). First, although adherence to study drug was monitored, adherence to background therapy was not.  AL, Graham  EA, All fatal adverse events were assessed by the investigator as unrelated to study drug. Corresponding Author: Anne C. Goldberg, MD, Washington University School of Medicine, Campus Box 8127, 660 S Euclid, St. Louis, MO 63110 ( Adverse events leading to discontinuation that occurred in more than 0.5% of patients in either treatment group were myalgia (1.0% bempedoic acid, 0.8% placebo), increased aspartate aminotransferase level (0.6% bempedoic acid, 0% placebo), arthralgia (0.6% bempedoic acid, 0% placebo), muscle spasms (0.6% bempedoic acid, 0% placebo), cardiac arrest (0.2% bempedoic acid, 0.8% placebo), and fatigue (0.2% bempedoic acid, 0.8% placebo).  et al. Safety analyses were performed using the safety population, which included all patients who received 1 or more doses of study drug. The magnitude of LDL-C lowering was generally consistent among subgroups. Ballantyne  et al; European Atherosclerosis Society Consensus Panel. Randomization was performed centrally using an interactive web response system, with stratification by presence of heterozygous familial hypercholesterolemia and baseline statin intensity (low-, moderate-, or high-intensity15). Colantonio Trial Registration  Results from on-treatment analyses were also comparable with primary analyses for HDL-C, total cholesterol, apoB, and hsCRP. Median study drug exposure was similar in the bempedoic acid (363 days) and placebo (364 days) groups. This Medical News series offers an occasional roundup of developments in cardiovascular medicine.

No other disclosures were reported. As a prodrug, it becomes activated in the hepatocyte, thus avoiding potential muscle adverse effects associated with statins. In an exploratory analysis, LDL-C lowering at week 12 in patients who maintained stable background lipid-lowering therapy (≈95% of patients) was consistent with that in the overall population. Changes from baseline in triglyceride levels were comparable between treatment groups, and statistically significant reductions in HDL-C levels were observed in the bempedoic acid group (P < .001) (eTable 2 in Supplement 3). Participant Flow in the CLEAR Wisdom Randomized Clinical Trial, Figure 2. Phase 3, randomized, double-blind, placebo-controlled clinical trial conducted at 91 clinical sites in North America and Europe from November 2016 to September 2018, with a final date of follow-up of September 22, 2018. Neither the difference in statin usage nor the variance in baseline LDL-C levels affected overall LDL-C reduction with bempedoic acid. Ezetimibe use and LDL-C goal achievement: a retrospective database analysis of patients with clinical atherosclerotic cardiovascular disease or probable heterozygous familial hypercholesterolemia. Bempedoic acid is a new type of cholesterol-fighting drug that doesn't come with muscle-related side effects common with statins and could be an alternative. Products like Vytorin, Merck’s fixed-dose combination of ezetimibe and simvastatin, can offer LDL-cholesterol reductions approaching that of the high potency statins, and it is this level of efficacy that can make the difference for statin intolerant patients who are at higher risk for atherosclerotic CV disease. Additional treatment options are needed for patients who do not achieve sufficient reduction in low-density lipoprotein cholesterol (LDL-C) level with available lipid-lowering therapies. The majority of adverse events (430/548 [78.5%]) were mild or moderate in intensity, and most (425/548 [77.6%]) were classified by the investigator as not related or unlikely related to study drug treatment. 3 Unlike statins, bempedoic acid is administered as a prodrug and is converted to active coenzyme A form by … Gout and increased blood uric acid level were experienced, respectively, by 2.1% and 2.7% of patients in the bempedoic acid group and 0.8% and 0.4% of patients in the placebo group.  C, Blackwell If priced similarly to branded statins or Zetia/Ezetrol, DRG’s Dyslipidemia market forecast for 2016-2026 projects that bempedoic acid could be prescribed to millions of people, and make billions of dollars. Baseline LDL-C, non–HDL-C, total cholesterol, triglycerides, and HDL-C values were defined as the mean of the last 2 nonmissing values on or before day 1; for other parameters, baseline was defined as the last value prior to the first dose of study drug.  EM, Ahmad At baseline, mean LDL-C level was 120.4 (SD, 37.9) mg/dL. Effect of Bempedoic Acid on Low-Density Lipoprotein Cholesterol (LDL-C) Level, Table 1. A, Error bars indicate 95% CIs. Treatment-emergent adverse events occurred in 70.1% of patients in the bempedoic acid group and 70.8% of patients in the placebo group (Table 3). Greater clarity regarding event risk reduction with bempedoic acid will come from the ongoing 12 600-patient cardiovascular outcomes trial (CLEAR Outcomes [NCT02993406]). Similar to this 52-week trial, a statistically nonsignificant difference in the incidence of major adverse cardiovascular events with bempedoic acid (4.6%) vs placebo (5.7%) (relative risk, 0.81 [95% CI, 0.56 to 1.17]) was observed in CLEAR Harmony. Patients were excluded from the study if they had a total fasting triglyceride level of 500 mg/dL (5.6 mmol/L) or higher, body mass index 50 or greater (calculated as weight in kilograms divided by height in meters squared), severe renal impairment (estimated glomerular filtration rate <30 mL/min/1.73 m2), recent (within 3 months of screening) CHD event, or clinically significant disease that could interfere with study participation.
