NCT03944577

Brief Summary

Coronary allograft vasculopathy (CAV) is diffusely accelerated atherosclerosis of a transplanted heart. Evolocumab (Repatha) is an FDA-approved drug for lowering low density lipoprotein (LDL) in patients who have not received a heart transplant. This drug works as a PCSK9-inhibitor. The primary objective of this study is to measure the impact of PCSK9-inhibitors on serum LDL in heart transplant patients with CAV after 12 weeks compared to baseline.

Outcome Measures

Primary Outcomes (1)

  • Percent Change in Serum LDL (mg/dL) After 12 Weeks of Evolocumab

    The primary outcome measure for this study was percent change in LDL from baseline after 12 weeks of evolocumab therapy. Serum LDL was measured at baseline and after 12 weeks of evolocumab therapy. This primary endpoint was used in prior phase 2 trials investigating evolocumab in other patient populations. Wilcoxon matched-pairs signed rank test was used for statistical assessment.

EXPERIMENTAL

Patients who will receive the study drug.

Drug: Evolocumab

Interventions

Enrolled study participants will be treated with evolocumab (Repatha) 140 mg injected subcutaneously every 2 weeks for 52 weeks. All study participants will receive instruction on correct self-administration by research pharmacists. Study drug will be mailed to patients on a monthly basis for self-administration by patients. The evolocumab dose (140 mg every 2 weeks) will remain constant for the duration of the study. Side effects will be assessed on a quarterly basis. Serious adverse events considered related to treatment, death, and pregnancy will all result in immediate discontinuation of the study drug.
