Overview
This is a 2-part study evaluating the efficacy and safety of lorundrostat (an aldosterone synthase inhibitor [ASI]) for the treatment of hypertension in subjects with CKD and albuminuria while receiving stable treatment with an angiotensin converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB) either in combination with dapagliflozin, or alone.
Description
Part A is a double-blind, placebo-controlled, parallel arm study. Part A consists of up to a 2-week Screening period, followed by two 8-week treatment periods (Period 1 and Period 2) separated by a 4-week single-blind washout phase. Part B consists of up to a 2-week Screening period, followed by an open-label, single arm, dose escalation 8-week treatment phase.
