This seamless two-stage phase II/III clinical trial aims to evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for essential hypertension. Stage 1 is a phase II, multicenter, open-label, randomized trial to determine the optimal treatment strategy. Stage 2 is a phase III, multicenter, randomized, double-blind trial investigating the efficacy and safety of optimal treatment strategy compared to sham control.
