Sponsor

Enrollment

121 participants

Start Date

Mar 1, 2023

Study Type

INTERVENTIONAL

Conditions

Summary

This is a randomized placebo-controlled study in treated and suppressed HIV-infected individuals aged ≥40 years with either known CVD or 1 CVD risk factor to study the effect of Bempedoic acid (BA) on safety, arterial inflammation as assessed by FDG-PET/CT, lipids, inflammation, immune activation, cardiometabolic indices, and non-calcified plaque (NCP) in the coronary arteries (assessed by coronary CT angiography, CCTA). This trial will be enrolled at UCSF and UCLA. Collaborators at Massachusetts General Hospital (MGH) will serve as the core facility for imaging.


Eligibility

Min Age: 40 Years

Inclusion Criteria9

  • Documented HIV infection
  • On continuous antiretroviral therapy and virologically suppressed HIV infection for ≥12 weeks prior to study entry
  • CD4 T-cell count ≥ 200 cells/mm3
  • Male or female between the ages ≥ 40 years of age
  • LDL-C ≥ 50 mg/dL
  • Documented cardiovascular disease as defined by: 1. Prior myocardial infarction, 2. Prior cerebrovascular disease, 3. Prior peripheral arterial disease, 4. History of percutaneous coronary intervention, 5. History of coronary artery bypass graft OR 6. Angiographic evidence of \>50% stenosis in at least one coronary artery\] OR 1 CVD risk factor (T2DM, current smoking, hypertension, dyslipidemia, hsCRP≥2mg/L, family history)
  • TBR of \>1.6 of the MDS of the carotid/aorta at baseline. This baseline arterial TBR cutoff excludes the rare individual that lacks appreciable arterial inflammation. It is notable that while 5-10% of uninfected individuals will have lower TBRs, it is rare that an HIV infected individual will fall below this range.
  • Female subjects must either be of non-childbearing potential (defined as post-menopausal or amenorrhea \> 12 months) or agree to use two forms of contraception (one hormonal and one barrier) throughout the study and for at least one month following study completion and have a negative pregnancy test at screening and prior to the first dose of drug.
  • Males must use at least one method of contraception throughout the study.

Exclusion Criteria10

  • Pregnant/nursing women (as there is no data on bempedoic acid in this setting)
  • Diabetes requiring insulin (as insulin treatment alters the uptake of 18FDG)
  • AST/ALT or alkaline phosphatase \>2x ULN
  • Triglycerides \>500 mg/dL at screening
  • Cancer within the last 5 years with exception of squamous cell carcinoma and basal cell carcinoma
  • Individuals on simvastatin \>20mg or pravastatin \>40mg. All other dosages and statins will be permitted with close monitoring for myopathies including assessment of CK levels
  • Nephrotic syndrome or eGFR \<30 mL/min/1.73m2
  • Cytopenias which include 1) WBC \<3.5 x103/uL 2) Platelet \<120 x103/uL 3) ANC \<1.5 x103/uL, and absolute lymphocytes \<0.8 x 103/uL
  • Anemia as fined by Hgb \<10 g/dL
  • Acute systemic infection within 30 days

Interventions

DRUGBempedoic acid

Bempedoic Acid is an oral first-in-class small molecular adenosine triphosphate (ATP)-citrate lyase (ACL) inhibitor which lowers LDL-C by inhibition of cholesterol synthesis in the liver. ACL is an enzyme upstream of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase in the cholesterol biosynthesis pathway. Inhibition of ACL by bempedoyl-CoA results in decreased cholesterol synthesis in the liver and lowers LDL-C in blood via upregulation of LDL receptors and concomitant suppression of hepatic fatty acid biosynthesis. BA has been studied in \>4300 individuals and is currently being studied in \>14,000 individuals in CLEAR Outcomes (NCT02993406).
