A Study to Evaluate ALN-AGT01 in Patients With Hypertension

A Phase 1, Randomized, Double-Blind, Placebo-Controlled Single Dose and Active Comparator-Controlled Multiple Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Subcutaneously Administered ALN-AGT01 in Patients With Hypertension

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) effects of subcutaneous (SC) ALN-AGT01 (zilebesiran) 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.

• Parts A and B: Has body mass index (BMI) ≥18 and ≤35 kg/m^2; Part D: Has BMI >35 and ≤50 kg/m^2; Part E: Has BMI ≥18 kg/m^2 and ≤50 kg/m^2
• Has a normal 12-lead electrocardiogram (ECG)
• Is a nonsmoker

Exclusion Criteria:

• Has secondary hypertension
• Has orthostatic hypotension
• Has estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73m^2
• Recently received an investigational agent
