Summary
This study was designed to see if certain immune cells (T cells) contribute to age-related blood vessel problems that raise heart disease risk. It planned to give a single injection of abatacept to adults aged 55-75 and measure changes in artery function and inflammation. However, the study was withdrawn before any participants were enrolled, so no results are available.
