Cholesterol Lowering Drug Shown to Cut Major Heart-Related Events and Risk of Death from Heart Disease by One-Third for Statin-Intolerant Patients
First-of-its-Kind Data Underscore Importance of Early Use of Drug Therapy as a Primary Prevention, Especially for Those Living with Diabetes
Today, a new trial revealed data on the effects of bempedoic acid – a non-statin cholesterol-lowering drug – on cardiovascular outcomes, demonstrating that patients with risk factors for coronary artery disease (CAD) and high cholesterol, particularly those with diabetes, should be treated with a cholesterol-lowering drug. The results were presented as a late-breaking poster at the 83rd Scientific Sessions of the American Diabetes Association® (ADA) in San Diego, CA and simultaneously published in The Journal of the American Medical Association.
Statins are a common type of cholesterol-lowering medicine that can help reduce the amount of low density lipoprotein, otherwise known as LDL-C or "bad cholesterol" in the blood. However, about 1 in every 10-12 patients have statin-intolerance (SI), and there is also a 30% increase in SI associated with diabetics, females, obesity, and other health and ethnicity-related factors. Some studies have found that the use of statins increases blood sugar due to the medicine stopping insulin from processing blood sugar properly. As a result, this can put people at higher risk of developing type 2 diabetes. The study aimed to determine the effects of bempedoic acid on cardiovascular outcomes in statin-intolerant patients.
The CLEAR Outcomes trial was a masked, randomized, trial that enrolled 13,970 statin-intolerant patients. This study included 4,206 patients with risk factors for heart disease but without a prior heart-related event (primary prevention). The mean age for these participants was 68 years, 67% had diabetes and 59% were female. The primary efficacy endpoint was a composite of cardiovascular death, nonfatal myocardial infarction (MI), nonfatal stroke, or coronary revascularization. The study showed a 22% reduction in LDL-C with the drug bempedoic acid. Treatment for 40 months was associated with a significant risk reduction for the primary endpoint, 111 (5.3%) versus 161 events (7.6%), adjusted hazard ratio (HR) 0.70, 95% CI 0.55-0.89, P=0.002. This represents a 30% reduction in major heart-related events. A 39% reduction in the risk of death from heart disease was also observed.
“We know early prevention measures are critical to slowing the progression of heart disease, especially for people with comorbidities like diabetes,” said the study’s lead author Steven E. Nissen MD, Chief Academic Officer, Heart Vascular & Thoracic Institute at Cleveland Clinic. “Unfortunately, less than half of patients in the US similar to the study patient population are being treated with cholesterol-lowering drugs – leaving them at risk. The results presented today are a wake-up call for the clinical community that patients with risk factors for coronary disease and high cholesterol, particularly those with diabetes, should be treated with a cholesterol-lowering drug.”
Bempedoic acid is a novel, nonstatin drug currently approved for 2 groups of patients by the FDA, including those with heterozygous familial hypercholesterolemia and those with atherosclerotic cardiovascular disease. The drug is also the first adenosine triphosphate-citrate lyase (ACL) inhibitor for use as an LDL-C lowering therapy and works by inhibiting cholesterol biosynthesis in the same pathway as statins.
The authors of this study note that further analysis is needed on the role bempedoic acid has on cholesterol-lowering versus anti-inflammatory effects.
