Focal Segmental Glomerulosclerosis Clinical Trial (FSGS-CT)

Participants assigned to this group will initiate treatment with CSA, 5-6 mg/kg per day with a 250 mg/day maximum starting dose, divided into two daily doses. The CSA dose will be adjusted based on drug levels determined at specified study visits in order to achieve a 12-hour trough concentration in the therapeutic range of 100-250 ng/ml.

"MMF, 25-36 mg/kg per day with a maximum dose of 2 g/day divided into two daily doses. The dose range reflects the use of fixed size (250 mg) capsules and application of defined daily doses to specific weight ranges (see Table below). In younger children or those participants who are unable to swallow capsules, a liquid formulation will be used to provide 36 mg/kg per day to a maximum of 2 g per day. The starting MMF dose will be 0.5-0.67 of the full dose for 2 weeks before advancing to the full dose for the duration of the 12-month treatment period.~Dexamethasone, 0.9 mg/kg per dose, with a maximum dose of 40 mg"
