Trial Outcomes & Findings for Effects of Eicosapentaenoic Acid on Endothelial Function in Diabetic Subjects (NCT NCT02422446)

NCT ID: NCT02422446

Last Updated: 2022-03-18

Results Overview

Digital pulse amplitude will be measured with a fingertip peripheral arterial tonometry (PAT) device (Endo-PAT2000, Itamar Medical) in a supine position. Baseline pulse amplitude will be measured for 5 minutes, then the arterial flow will then be interrupted for 5 minutes with a cuff placed on a proximal forearm. Pulse amplitude will be recorded electronically and analyzed by a computerized and automated algorithm. The change from the baseline measurement will be expressed as the reactive hyperemia index (RHI). We will calculate the pulse amplitude response to hyperemia for each 30-second interval as a ratio of the post-deflation pulse amplitude to the baseline pulse amplitude as described previously. The RHI ratio will be computed by dividing the ratio obtained on the test side over the ratio from the control finger. We will assess change in RHI ratio between baseline value and 12-week value after the intervention.

PRIMARY outcome

Change From Baseline in Endothelial Function at 12 Weeks Using Reactive Hyperemia Index (RHI)

Interval -29.0 to -29.0
-1.6 % change from baseline value
Interval -1.6 to -1.6

SECONDARY outcome

Timeframe: change between baseline and 12 weeks post-intervention

Population: Because the trial was terminated prematurely due to difficulties in finding suitable subjects, we were not able to measure any of the three biomarkers specified under the secondary outcome (ET-1, hsCRP, and Oxidized LDL).

Plasma hsCRP will be measured by Sandwich enzyme linked immunosorbent assay (ELISA). Plasma oxidized LDL and plasma ET-1 will be measured using a commercially available sandwich-enzyme immunoassay kit (R \& D).
