Effects of IL-1 Beta Inhibition on Vascular Inflammation in TET2 Clonal Hematopoiesis
Massachusetts General Hospital
Summary
The primary goal of this clinical trial is to test the hypothesis that the drug canakinumab (anti-IL-1B monoclonal antibody) decreases vascular inflammation when used by people with a history of coronary artery disease, including those with and without clonal hematopoiesis driven by mutations in TET2.
Description
This is a prospective, randomized, double-blind, placebo-controlled study to test the effects of canakinumab, an inhibitor of interleukin-1B, on vascular inflammation in individuals with coronary artery disease. Half of the trial population will have clonal hematopoiesis of indeterminate potential (CHIP) driven by mutations in TET2. Participants (total N=120) will be randomized 1:1 to receive canakinumab (n=60) versus placebo (n=60). Baseline assessment in all participants will include coronary CT angiography, and a subset of participants in each group (n=16 per group) will undergo SPECT imagi…
