Purpose Of Review:
A number of novel trials have assessed the efficacy of new lipid-lowering therapies in cardiovascular disease (CVD).
Recent Findings:
Proprotein convertase subtilisin kexin-9 inhibitors reduce low-density lipoprotein cholesterol (LDL-C) by 50-55%. A CVD outcome trial in patients with acute coronary syndromes with evolocumab achieved a LDL-C of 0.8 mmol/l (31 mg/dl) and a 20% relative risk reduction in CVD events in 2.2 years. Cholesterol ester transfer protein inhibitors raise high-density lipoprotein cholesterol and can lower LDL-C. Anacetrapib reduced coronary artery disease events by 7%, but not wider composite CVD outcomes, in a population with chronic CVD with pretreatment LDL-C of 1.6 mmol/l (62 mg/dl). The conflicting outcomes of cholesterol ester transfer protein inhibitor trials means these compounds are not being developed further. Trials using lipid drugs targeting inflammation have previously been generally unsuccessful, but recent data on the interleukin-1B receptor antagonist canakinumab has proven the concept of intervention on inflammation in atherosclerosis by showing a reduction in acute coronary interventions, but at the predictable cost of increased infections.
Summary:
Despite the success of proprotein convertase subtilisin kexin-9 inhibition, the ability to achieve low LDL-C with off-patent medications and the costs of novel therapies will limit their use even in high-risk patients and confine them to the highest-risk sub-groups of patients.
Insights
New lipid-lowering therapies show promise for cardiovascular disease (CVD) prevention. Proprotein convertase subtilisin kexin-9 inhibitors effectively reduce LDL-C, but cost may limit their widespread use in CVD patients.
Area of Science:
- Cardiovascular Medicine
- Pharmacology
- Atherosclerosis Research
Background:
- Novel lipid-lowering therapies are being evaluated for cardiovascular disease (CVD) management.
- Understanding the efficacy and limitations of these new treatments is crucial for clinical practice.
Purpose of the Study:
- To review recent trials assessing novel lipid-lowering therapies for cardiovascular disease (CVD).
- To evaluate the effectiveness of proprotein convertase subtilisin kexin-9 inhibitors and cholesterol ester transfer protein inhibitors.
- To assess the role of inflammation-targeting drugs in atherosclerosis.
Main Methods:
- Review of recent clinical trials on lipid-lowering therapies.
- Analysis of outcomes from trials involving proprotein convertase subtilisin kexin-9 inhibitors (e.g., evolocumab).
- Evaluation of cholesterol ester transfer protein inhibitors (e.g., anacetrapib) and inflammation-targeting agents (e.g., canakinumab).
Main Results:
- Proprotein convertase subtilisin kexin-9 inhibitors significantly reduce LDL-C and CVD events.
- Cholesterol ester transfer protein inhibitors showed mixed results, leading to discontinuation of development.
- Canakinumab demonstrated a reduction in acute coronary interventions by targeting inflammation, with increased infection risk.
Conclusions:
- While effective, the high cost of novel therapies like proprotein convertase subtilisin kexin-9 inhibitors may restrict their use to high-risk patients.
- Targeting inflammation in atherosclerosis is a viable strategy, but requires careful risk-benefit assessment.
