Abstract

The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) found a 36% reduction in major adverse cardiovascular events (MACE) with pitavastatin in people with HIV. Little is known about the relationship between lipid lowering and MACE in this population. We evaluated pitavastatin effects on lipids and examined mediation of pitavastatin effects on MACE through lipid lowering. REPRIEVE was a randomised, double-blind, placebo-controlled phase 3 trial evaluating pitavastatin (4 mg daily) or placebo for prevention of MACE in people with HIV. Participants aged 40-75 years, on stable combination antiretroviral therapy (ART), and at low-to-moderate atherosclerotic cardiovascular disease risk with minimally elevated LDL were followed up for a median of 5·6 years. Centrally tested fasting lipids were captured at entry and annually thereafter. The primary MACE outcome, reported previously, was time to first MACE. Here, we report secondary outcomes on fasting lipids. Linear mixed-effects models were used for assessment of the pitavastatin effect on lipids, Cox regression for relationship of lipids to MACE, and Vansteelandt method for mediation analysis. REPRIEVE enrolled 7769 participants from March 26, 2015, to July 31, 2019, in 12 countries across five Global Burden of Diseases super-regions. The median baseline LDL was 108 mg/dL, and similar across treatment groups. Pitavastatin effects were primarily observed on LDL, with a modest reduction in triglycerides and no apparent effect on HDL. Based on the longitudinal data modelling, the estimated treatment group difference in LDL at month 12 (pitavastatin minus placebo) was -30 mg/dL (95% CI -31 to -29), corresponding to a 30% reduction. The estimated risk of LDL of ≥100 mg/dL at month 12 was 0·18 in the pitavastatin group and 0·57 in the placebo group (relative risk 0·32, 95% CI 0·30-0·34). A 30% lower time-updated average LDL was associated with 20% lower risk of primary MACE (hazard ratio 0·80, 95% CI 0·68-0·94). Of the pitavastatin effect on MACE, 68% was estimated to be mediated through LDL, although with low precision (95% CI 15-574). LDL is strongly related to MACE, and LDL lowering should be an important goal of primary cardiovascular prevention in people with HIV, even in those with minimally elevated LDL. Treatment should aim to achieve accepted primary care prevention targets for LDL. US National Institutes of Health, Kowa Pharmaceuticals America, Gilead Sciences, and ViiV Healthcare.
