Janus Kinase-STAT Inhibition to Reduce APOL1 Associated Kidney Disease

Description

The purpose of this study is to determine if the drug, baricitinib, is safe and effective in reducing high levels of albumin in the urine (albuminuria) in African American/Blacks with APOL1- associated focal segmental glomerulosclerosis (FSGS) and non-diabetic APOL1-associated chronic kidney disease due to hypertension (HTN-CKD).
