Trial Outcomes & Findings for A Trial to Evaluate the Effect of C21 on Endothelial Dysfunction in Subjects With Type 2 Diabetes (NCT NCT05831644)
NCT ID: NCT05831644
Last Updated: 2024-11-12
Results Overview
Reactive hyperemia index (RHI) score as measured by EndoPAT (Endothelial pulse amplitude tonometry (PAT)). The EndoPAT software, provided with the device, is calculating the RHI using a computerised, automated algorithm. Reactive Hyperemia Index (RHI) score is a post-to-pre occlusion pulse amplitude tonometry signal ratio in the occluded arm relative to the same ratio in the control arm, and corrected for baseline vascular tone. RHI is a measure of endothelial function. Normal value: RHI \> 1.67. Abnormal value: RHI ≤ 1.67. There is no theoretical minimum and/or maximum values for the RHI score. A lower RHI score following C21 compared to placebo is the desired outcome.

SECONDARY outcome
Timeframe: Maximum 15 days after first Investigational Medical Product (IMP) intake.The EndoPAT software, provided with the device is calculating the the Augmentation index (AI) using a computerised, automated algorithm. Augmentation index is a measurement of vascular stiffness. Augmentation index is calculated from PAT pulses based on the following formula AIx = 100 × (Augmentation pressure)/(Pulse Pressure). Ideally the augmentation index is somewhere between 20-80, but can be both negative and positive depending on the value of the augmentation pressure. A higher value is indicative of vascular stiffness.
