A Study of Praliciguat in Participants With Focal Segmental Glomerulosclerosis (FSGS)

This is a Phase 2, randomized, double-blind, placebo-controlled, multicenter study designed to evaluate the efficacy and safety of praliciguat in adults with biopsy-confirmed focal segmental glomerulosclerosis (FSGS). Participants will be randomized 1:1 to receive praliciguat or placebo for initial 24 week treatment period. Following this double-blind period, all participants will receive praliciguat in an open-label extension for an additional 24 weeks.

Inclusion Criteria: 1. UPCR ≥1 (g/g) during screening. 2. On maximally tolerated ACEi or ARB per principal investigator discretion within 1 month of informed consent. 3. Estimated glomerular filtration rate ≥25 milliliters per minute per 1.73 square meters by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. 4. Kidney biopsy collected within 5 years of screening consistent with FSGS or kidney biopsy collected ≥5 years prior to screening consistent with FSGS plus the presence of a pathogenic gene mutation known to be associated with FSGS. Exclusion Criteria: 1. Collapsing FSGS in the kidney biopsy report. 2. Sickle cell disease. 3. HbA1c \>8%. 4. Uncontrolled hypertension (≥160/100 millimeters of mercury).
