Results demonstrated that a single dose of investigational zilebesiran led to sustained serum angiotensinogen (AGT) and blood pressure (BP) reductions through six months, supporting quarterly and potentially biannual dosing regimens. Additional findings from other parts of the Phase 1 study showed that zilebesiran was safe and well tolerated during salt restriction and when administered concomitantly with irbesartan, an oral renin-angiotensin-aldosterone system inhibitor (RAASi).

Across various cohorts in the Phase 1 study, zilebesiran was shown to be generally well tolerated, supporting continued development.
