A Study to Evaluate ALN-AGT01 in Patients With Hypertension

Phase 1
Completed
Conditions
Hypertension
Interventions
Drug: ALN-AGT01-Matching Placebo
Drug: Irbesartan-Matching Placebo
Registration Number
NCT03934307
Lead Sponsor
Alnylam Pharmaceuticals
Brief Summary

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.
