Preparing for a New Era in IgAN Treatment: Staying up to Date on the Latest Developments in Targeted Immune-Modulating Therapies - Episode 7

Use of Povetacicept in Treatment of IgA Nephropathy

Published on: 

Drs Jonathan Barratt and Brad Rovin comment on clinical trial data regarding the use of povetacicept for the treatment of IgAN.

This is a video synopsis/summary of a panel discussion involving Jonathan Barratt, PhD, FRCP, and Brad Rovin, MD.

Jonathan Barratt, PhD, FRCP, and Brad Rovin, MD, discuss the latest data on drugs targeting the B-cell activating factor (BAFF) and A proliferation-inducing ligand (APRIL) axis in IgA nephropathy (IgAN), presented at the American Society of Nephrology (ASN) meeting. The conversation highlights the growing interest and excitement in the nephrology community about these emerging therapies.

Dr Barratt mentions recent data on sibeprenlimab and povetacicept and emphasizes the significant attention these drugs received at the ASN meeting. He specifically discusses the promising results from sibeprenlimab, showcasing consistent and effective APRIL inhibition, resulting in a reduction in galactose-deficient IgA1 (Gd-IgA1) and translation to reduced proteinuria.

Dr Rovin provides insights into the presentation of data on povetacicept, emphasizing its impressive proteinuria reduction, even at what is referred to as a "low dose." Both experts acknowledge the need for further dose-ranging studies to determine optimal dosing.

The discussion extends to the potential applications of these drugs beyond IgAN. Dr Barratt highlights a patient with membranous nephropathy treated with povetacicept, showing a significant reduction in anti-PLA2R titers, suggesting a potential broader impact on autoantibody-mediated diseases.

The experts discuss the ability of these drugs to target different cell populations, providing a unique advantage in diseases where both pathogenic antibodies and autoantibodies play a role. Dr Barratt emphasizes the potential benefits in lupus, envisioning combined approaches with BAFF and APRIL inhibition.

Dr Rovin concludes by expressing excitement about the multifaceted applications of these drugs in various diseases and suggests rethinking the use of immunosuppression, aiming for effective treatment with reduced overt immunosuppression. The conversation underscores the transformative potential of BAFF and APRIL inhibitors in reshaping the landscape of nephrology therapeutics across multiple diseases.
