Brief Summary:
This is a phase 2a study evaluating the safety and tolerability of multiple ascending doses of GFB-887 in patients with diabetic nephropathy (DN), focal segmental glomerulosclerosis (FSGS), and treatment-resistant minimal change disease (TR-MCD).

Condition or disease Intervention/treatment Phase
Kidney Diseases Diabetic Nephropathies Glomerulosclerosis, Focal Segmental Nephrosis, Lipoid Urologic Diseases Diabetes Complications Diabetes Mellitus Endocrine System Diseases Glomerulonephritis Nephritis Nephrosis Drug: GFB-887 Drug: Placebo Phase 2

Detailed Description:
Approximately 125 patients will be enrolled in this study across the United States. Patients with DN and FSGS/TR-MCD will be randomized in 3 ascending dose cohorts to receive either GFB-887 or placebo.
