Description

Summary

The study is being conducted to determine if cenicriviroc mesylate (CVC) will decrease vascular inflammation as measured by 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) imaging of the aorta.

Official Title

A Limited-Center, Prospective, Double-Blind, Placebo-Controlled Study to Evaluate the Effects of Cenicriviroc Mesylate on Arterial Inflammation in People Living With HIV

Details

This is a double-blind, placebo-controlled phase II clinical trial comparing the intervention of CVC versus placebo for a duration of 24 weeks on arterial inflammation evaluated by FDG-PET/CT imaging. A total of 93 participants will be randomized 2:1 to the CVC arm (Arm A) or placebo for CVC arm (Arm B). Stratification by statin use at randomization will ensure even distribution of statin use between the treatment groups.

  6. At least one of the following cardiovascular risk factors (current diagnosis or receiving treatment, except where a time period is specified):
  7. Clinical atherosclerotic disease (symptomatic atherosclerotic lesions in any vessel)
  8. Subclinical atherosclerotic disease (coronary artery calcification [CAC] >10 or presence of non-obstructive plaques)
  9. DM or prediabetes (hemoglobin A1c [HbA1c] ≥5.7%) or impaired fasting glucose (documented fasting glucose of >100 mg/dL within 6 months prior to study entry) or insulin resistance (HOMA-IR ≥2.6) or any one of these laboratory values within 6 months prior to study entry
  10. Obesity (body mass index [BMI] ≥30 kg/m2) or enlarged iliac waist circumference (>40 inches in males, >35 inches in females)

  11. History of hypertension or blood pressure ≥130/80 mmHg measured during screening
  12. Elevated LDL cholesterol (fasting LDL of >160 mg/dL; result from sample taken within 90 days prior to study entry can be used)
  13. Low HDL cholesterol (<40 mg/dL; result from sample taken within 90 days prior to study entry can be used)
  14. Smoking (any current tobacco smoking)
  15. Family history of premature CAD (first degree relative with CAD prior to age 55 for male relative and 65 for female relative; participant report is acceptable)
  16. hsCRP >2.0 mg/L within 90 days prior to study entry without an active infection or acute illness at the time the sample was obtained
  17. The following laboratory values obtained within 90 days prior to study entry:
  18. Absolute neutrophil count (ANC) >750/mm3

  19. Platelet count >100,000/mm3

  20. Aspartate aminotransferase (AST) (SGOT) ≤5x upper limit of normal (ULN)
  21. Alanine aminotransferase (ALT) (SGPT) ≤5x ULN
  22. Alkaline phosphatase ≤5x ULN

  24. Pre-entry FDG-PET/CT imaging (within 60 days prior to study entry) that has been deemed:
  25. Interpretable as assessed by the central imaging core laboratory AND
  26. Without incidental findings that will preclude participation in the study at the discretion of the site investigator
  27. No plans to receive immunizations 7 days prior to the week 24 study visit.
  28. . For study candidates of child-bearing potential, negative serum or urine pregnancy test within 90 days prior to study entry and prior to starting study treatment at study entry. Reproductive potential is defined as individuals who have reached menarche and individuals who have not been post-menopausal for at least 12 consecutive months with follicle-stimulating hormone (FSH) ≥40 IU/mL or 24 consecutive months if an FSH is not available, or have not undergone surgical sterilization (e.g., hysterectomy, bilateral oophorectomy, tubal ligation or salpingectomy).
  29. . If participating in sexual activity that could lead to pregnancy, willingness of person of childbearing potential to use two forms of contraception while receiving study medication and for 3 months after stopping study medication as required.
  30. . Individuals ≥45 years of age.
  31. . Ability and willingness of participant or legal guardian/representative to provide informed consent.
