A Randomized, Multicenter, Double-blind, Parallel, Active-control Study of the Effects of Sparsentan, a Dual Endothelin Receptor and Angiotensin Receptor Blocker, on Renal Outcomes in Patients With Primary FSGS

Descripción detallada

This is a randomized, multicenter, double-blind, parallel, active-control study. Approximately 300 patients aged 8 to 75 years (inclusive) will be enrolled in the study. The study will be conducted in approximately 300 study centers, globally. The investigational drug (sparsentan) is a dual-acting angiotensin receptor blocker and endothelin receptor antagonist. The active control is irbesartan. Patients who meet eligibility criteria will require washout from renin-angiotensin-aldosterone system (RAAS) blockers, if applicable prior to their first dose of study drug. Patients will be randomly assigned in a 1:1 ratio to receive either sparsentan or active control (irbesartan). After completing the double-blind portion of the study, patients may participate in the open-label extension for treatment with sparsentan if they meet eligibility criteria. Primary completion date represents the anticipated completion date of the double-blind portion of the study. Study completion date represents the anticipated completion date of the open-label extension portion of the study.
