MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Clinical trials of lipid-lowering therapies (LLTs), including statins, often report variations in treatment response regarding effects on low density-lipoprotein cholesterol (LDL-C) levels, although LDL-C reductions are fairly consistent between trials. Praluent is generally well tolerated, however hyporesponsiveness exists in few patients.

Potential causes for variation in patient responsiveness to Praluent include lack of receipt of active study drug, changes in concurrent LLTs, inaccurate or unrepresentative baseline lipid levels, concurrent acute-phase illness, and biological nonresponsiveness.

This analysis evaluated patients pooled from 10 ODYSSEY trials to assess characteristics of patients with hyporesponsiveness to Praluent, defined as <15% LDL-C reduction from baseline at all analyzed time points.

Overall, only 1% of patients (n=33) had <15% LDL-C reduction at all time points. Prolonged hyporesponsiveness to Praluent was rarely associated with Praluent antidrug antibodies. Of the 33 patients with <15% LDL-C reduction at all study timepoints, 27 had undetectable or missing alirocumab levels, absence of pharmacokinetics analyses, or early treatment discontinuation.

MedicalResearch.com: What should readers take away from the data that Sanofi and Regeneron is presenting at ESC Congress 2017?   

Response: This year at European Society of Cardiology (ESC,) we are pleased to present analyses that further demonstrate additional efficacy and tolerability of Praluent (alirocumab).

While statins remain the first-line treatment, Praluent has shown a consistent benefit as an additional therapy to high-intensity statins in patients with clinical atherosclerotic cardiovascular disease (ASCVD) and/or heterozygous familial hypercholesterolemia (HeFH), allowing many patients to achieve low-density lipoprotein (LDL) cholesterol levels previously considered unattainable in this patient population.

Our data further emphasize the need for additional cholesterol-lowering options in these high cardiovascular (CV) risk patient populations, including individuals living with diabetes
