Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a parallel, Phase 2a, double-blind, 6-arm study for the treatment of primary focal segmental glomerulosclerosis (FSGS) or primary minimal change disease (MCD).

The purpose of this study is to measure the change in proteinuria and its impact on the rates of remission of nephrotic syndrome with frexalimab, brivekimig, or rilzabrutinib compared with placebo in participants with primary FSGS or primary MCD aged 16 to 75 years.

Study details for each participant include:

The study duration will be up to 76 weeks. The treatment duration will be 24 weeks. There will be up to 18 visits.

* UPCR ≥3 g/g at screening.
* eGFR ≥45 mL/min/1.73 m\^2 at screening.
* Documented history of UPCR (or 24-hour urine protein) reduction by \>40% in response to corticosteroid or other immunosuppressive therapy when pre-treatment UPCR was ≥3.5 g/g (or pre-treatment 24-hr urine protein was 3.5 g/day if 24-hour urine protein is used).
* ≤10 mg/day prednisone or equivalent and stable starting at least 1 week prior to randomization.
* On stable dose of RAAS for ≥4 weeks prior to screening (if applicable); starting RAAS inhibitors or changing the dose will not be allowed during the double-blind or OLE treatment period.
