BOSTON – The PCSK9 inhibitor alirocumab was superior to ezetimibe in meeting multiple lipid goals In patients with type 2 diabetes, according to results from a pooled analysis of randomized clinical trials.
“Alirocumab is an efficient therapy to get patients at target, which is our clinical daily business and the reason to treat patients,” said investigator Dirk Müller-Wieland, MD, an internist at University Hospital Aachen, Germany.
Dr. Müller-Wieland and his colleagues conducted a pooled analysis of 407 individuals with type 2 diabetes enrolled in one of three randomized trials who had hypercholesterolemia despite background lipid-lowering treatments. They found a total of 241 patients with diabetes who had received alirocumab in the trials, and 166 who had received ezetimibe.
With alirocumab on top of statins, 75.0% of patients met a combined LDL cholesterol, non–HDL cholesterol, and apolipoprotein B threshold after 24 weeks of treatment, compared with 56.7% of patients receiving ezetimibe along with their statins, a significant difference, it was reported at the annual meeting of the American Association of Clinical Endocrinologists.
The proportion of patients achieving LDL levels of less than 70 or 100 mg/dL (depending on cardiovascular risk) was significantly larger in the alirocumab group than in the ezetimibe group, at 80.8% versus 64.3%, Dr. Müller-Wieland reported.
In patients with extreme cardiovascular risk, the proportion of patients achieving LDL levels of less than 55 mg/dL was 66.0% in the alirocumab group, compared with 36.6% in the ezetimibe group, suggesting the PCSK9 inhibitor was “much more efficient than ezetimibe” in reaching that goal, Dr. Müller-Wieland said in a video interview.
For patients in the extreme cardiovascular risk category, as defined in recent guidelines, the AACE recommends a new LDL treatment goal of less than 55 mg/dL, Dr. Müller-Wieland noted.
Significant differences in favor of alirocumab were also reported for the proportion of patients achieving non-HDL and ApoB goals, the report showed.
Adverse events related to treatment occurred in a similar proportion of patients in the alirocumab and ezetimibe groups, according to the investigators.
