Trial Outcomes & Findings for Impact of Evolocumab in Cardiac Transplant Patients With CAV (NCT NCT03944577)

NCT ID: NCT03944577

Last Updated: 2024-06-03

Results Overview

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.

PRIMARY outcome

Timeframe: 12 weeks

Population: This single arm study investigated the impact of PCSK9 inhibition via evolocumab on serum LDL in heart transplant patients with CAV after 12 weeks compared to baseline. Percent Change in serum LDL will serve as the primary endpoint for comparison.

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.
