A Study of VCT220 in Participants With Hypertension and Obesity or Overweight

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase II Study to Evaluate the Efficacy and Safety of VCT220 in Participants With Hypertension and Obesity or Overweight.

The purpose of this study is to explore the safety and efficacy of VCT220 for the treatment of hypertension in participants with obesity or overweight.

4. Either treatment-naïve to antihypertensive therapy for ≥ 30 days prior to screening, or receiving a stable dose for ≥ 30 days of one or two of the following classes of antihypertensive medications: renin-angiotensin system inhibitors (ARB/ACEI), calcium channel blockers (CCB), or diuretics.
