The schematic diagram compares traditional versus precision medicine approaches to the treatment of FSGS. By categorizing FSGS into subtypes based on non-invasive molecular and genetic profiling, precision medicine enables initiation of disease modifying therapy that targets the injury pathway activated in an individual patient together with non-specific renoprotective drugs. This combined treatment regimen will increase the likelihood of a treatment response and achieve improved kidney health outcomes compared to sequential prescription of renoprotective agents followed by empirical immunosuppressive therapy (IST).

Povetacicept Shows Disease-Modifying Potential in IgAN and Primary MN | Docwire News Povetacicept showed sustained proteinuria reduction and stable glomerular filtration rate at 48 weeks for patients with IgA nephropathy and primary membranous nephropathy.

ICYMI: RUBY-3 demonstrates that targeting BAFF and APRIL with povetacicept can drive proteinuria reduction and immunologic remission in IgAN and pMN. #KidneyWk #nephsky #Nephrology #ClinicalTrials www.docwirenews.com/post/povetac...
