Insights
This study investigated PCSK9 inhibitors for people with HIV (PWH) at high cardiovascular risk. It assessed effects on arterial inflammation and coronary plaque, aiming to clarify potent lipid-lowering mechanisms in PWH.
Area of Science:
- Cardiology
- Infectious Diseases
- Pharmacology
Background:
- People with HIV (PWH) face elevated cardiovascular disease (CVD) risk.
- While statins offer moderate lipid lowering, potent strategies like PCSK9 inhibitors require evaluation for PWH.
- The impact of PCSK9 inhibitors on atherosclerosis markers in PWH is currently unknown.
Purpose of the Study:
- To evaluate the efficacy of PCSK9 inhibitors in reducing arterial inflammation and coronary plaque in people with HIV.
- To explore the mechanisms by which potent lipid lowering influences atherosclerosis pathogenesis in PWH.
Main Methods:
- The EPIC-HIV study is a randomized, placebo-controlled, double-blinded trial.
- Participants (aged ≥40, treated HIV, ≥1 CVD risk factor or prior event) received alirocumab or placebo (2:1 ratio).
- Assessments included 18F-FDG PET/CT, coronary CT angiography, and flow-mediated dilation at baseline and 1 year.
Main Results:
- The primary outcome is the change in arterial inflammation (target-to-background ratio on PET/CT) from baseline to 1 year.
- Secondary outcomes include changes in noncalcified coronary plaque and endothelial function.
- Safety was assessed per the intention-to-treat principle.
Conclusions:
- The EPIC-HIV study will provide crucial evidence on PCSK9 inhibitor effects in PWH.
- Findings will elucidate how potent lipid lowering impacts atherosclerosis in this population.
Rationale:
People with HIV (PWH) are at increased risk of cardiovascular disease. Moderate lipid lowering with statins has been demonstrated to reduce cardiovascular risk among PWH. Accordingly, evaluation of more potent lipid-lowering strategies for prevention is needed, especially for PWH at higher risk. Prior research suggests that proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors safely lower low-density lipoprotein cholesterol by 60% among people with HIV, but the impact of PCSK9 inhibitors on arterial inflammation, endothelial function, coronary plaque, or markers of immune dysfunction among PWH remains unknown.
Methods:
The effect of PCSK9 inhibition on cardiovascular risk in treated HIV infection study is a randomized, placebo-controlled, and double-blinded clinical trial. Adults at least 40 years old with treated and virally suppressed HIV and at least one cardiovascular risk factor (primary prevention) or a prior cardiovascular event (secondary prevention) are randomized in a 2:1 ratio to alirocumab or a matching placebo injected subcutaneously. 18F-fluorodeoxyglucose positron emission tomography/computed tomography, coronary computed tomographic angiography, and flow-mediated dilation of the brachial artery are conducted at baseline and after 1 year of treatment. The primary study outcome is the change in arterial inflammation assessed using the target-to-background ratio of the most diseased arterial segment on positron emission tomography/computed tomography from baseline to 1 year, and key secondary endpoints will include the change in noncalcified coronary plaque on coronary computed tomographic angiography, change in endothelial function, and safety according to the intention-to-treat principle.
Enrollment:
One hundred eighteen participants were randomized. The mean age was 59.5 years, and 6% were female.
Conclusions:
The effect of PCSK9 inhibition on cardiovascular risk in treated HIV infection study will provide evidence regarding the mechanisms by which potent lipid lowering with PCSK9 inhibitors may alter the pathogenesis of atherosclerosis among PWH.
