Details and patient eligibility

About

This is a randomized, double-blind (DB), placebo controlled, crossover study with a two-period, two-sequence (2x2) design evaluating the efficacy and safety of 25 mg QD lorundrostat (an aldosterone synthase inhibitor [ASI]) in addition to a SGLT2i 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). Subjects will be at least 18 years old with hypertension, and mild to severe CKD with albuminuria at the Screening Visit.

Full description

The study consists of up to a 2-week Screening period, a 2-week run-in period where subjects will either begin study provided dapagliflozin 10 mg or continue on their regularly prescribed SGLT2i, and two DB 4-week treatment periods separated by a 4-week washout period. Subjects will be randomized (1:1) to two treatment sequences: lorundrostat-placebo (LP) and placebo-lorundrostat (PL).
