A Study to Evaluate ALN-AGT01 in Patients With Hypertension

Study Description
Brief Summary:
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) effects of subcutaneous (SC) ALN-AGT01 in participants with hypertension. The study will be conducted in 4 parts: Part A will be a single ascending dose (SAD) phase in hypertensive participants, Part B will be a single dose (SD) phase in hypertensive participants with controlled salt intake, Part D will be a MD phase in hypertensive participants who are obese, and Part E will be an open-label SD phase with co-administration of irbesartan in hypertensive patients.
