ClinConnect Summary

The EPIC-HIV Study is a clinical trial designed to explore how a medication called alirocumab, which lowers cholesterol, affects heart health in people living with HIV. Researchers are particularly interested in understanding whether this treatment can reduce inflammation in the blood vessels and improve their function. This study will involve 140 participants aged 40 and older who have been treated for HIV and have a higher risk of heart disease due to factors like high cholesterol or a family history of heart problems.

To be eligible, participants must have controlled HIV (with low viral levels) and must have been on stable HIV treatment for at least 12 weeks. They should also have signs of potential heart issues, such as existing heart disease or risk factors like high blood pressure or high cholesterol. Throughout the study, participants will receive either the medication or a placebo (an inactive treatment) and will undergo regular check-ups to monitor their heart health. This trial is an important step in finding better ways to manage heart disease risks for people living with HIV.
