A Phase 2a Multiple Ascending, Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of GFB-887, a TRPC5 Channel Inhibitor, in Patients with Diabetic Nephropathy, Focal Segmental Glomerulosclerosis, and Treatment-Resistant Minimal Change Disease

After each study subject qualifies, they will be assigned to one of the 5 treatment groups. The participants of each group will be given multiple doses of study drug at different dose levels. A computer will automatically assign the subject to one of the dose levels as well as whether the subject are placed in the placebo or active drug group. Neither the study doctor and study staff will know who is assigned to placebo or active drug.The total duration of this study is 26 weeks, and the study subject will have a total of 17 visits over this period
