Pre-Conference Focus Day

Pre-Conference Glomerular Focus Day

Monday March 17, 2025

Advancing Therapeutics Options for Glomerular Disease

This year’s Glomerular Disease Focus Day aims to bring the spotlight onto the evolving landscape of glomerular disorders, which share complex pathophysiology and present significant challenges in both diagnosis and treatment. Building on the progress made in treating IgA nephropathy, this day will explore how recent advancements can be applied to other glomerular diseases, including focal segmental glomerulosclerosis, membranous nephropathy, and lupus nephritis. With breakthroughs in disease understanding and therapeutic development, there’s an opportunity to cross-leverage insights, accelerate drug discovery, and ultimately improve outcomes for all glomerular disease patients.
