Dapagliflozin and Endothelin Receptor Antagonism in Large Vessel Vasculitis (DERAIL-LVV)

Recruiting now · Phase 2

Conditions studied: Large Vessel Vasculitis, Giant Cell Arteritis (GCA), Takayasu Arteritis

In brief

Large vessel vasculitis (LVV) is a disease that causes damage to blood vessels. This damage to blood vessels can increase the risk of patients with LVV developing cardiovascular disease, including heart attacks and strokes. A chemical produced in the body called endothelin may contribute to this increase in cardiovascular disease risk by causing the vessels to stiffen and blood pressure to increase. It has previously been shown that by blocking the effects of endothelin, vessel stiffness and blood pressure improve. Bosentan is a tablet that blocks the effects of endothelin. Dapagliflozin is a sodium-glucose co-transporter 2 inhibitor that has been shown to improve blood vessel function and stiffness in patients with diabetes. The investigators plan to assess blood vessel function in those with LVV and participants without LVV. Participants with LVV will be given Bosentan and Dapagliflozin for 6 weeks, followed by Dapagliflozin for 4 weeks, to evaluate their impact on blood vessel function.
