ALT Three panels showing the changes from baseline in 24-hour urinary protein-to-creatinine ratio. Panel A is a bar chart that shows the change from baseline in the 24-hour urinary protein-to-creatinine ratio at week 34 (primary end point). Panel B is a graph shows the change from baseline in the 24-hour urinary protein-to-creatinine ratio at weeks 10, 26, and 34; from the mixed model for repeated measures. Panel C is a bar chart that shows the percentage of patients with a 50% or greater reduction from baseline in the 24-hour urinary protein-to-creatinine ratio at weeks 10, 26, and 34.

ALT Four panels showing the mean change in estimated glomerular filtration rate (GFR), annualized estimated GFR slope, and composite kidney-disease progression. Panel A is a graph that shows the mean change in the estimated GFR from baseline through week 104 for atacicept and placebo. Panel B is a bar chart that shows the mean change in the estimated GFR from baseline to week 52 for atacicept and placebo and the between-group difference. Panel C is a bar chart that shows the annualized estimated GFR slope through week 104 for atacicept and placebo and the between-group difference. Panel D is a bar chart that shows the number and percentage of patients who had a reduction from baseline in the estimated GFR of at least 30% that was sustained for at least 30 days and those who had progression to dialysis, kidney transplantation, or death (not including one patient in the placebo group who received transient dialysis for acute kidney injury).

ALT A bar chart from the Original Article "Interim Analysis of a Phase 3 Trial of Povetacicept in IgA Nephropathy.” The trial name, RAINIER AIS-D08, is in parentheses after the title. The chart shows change in 24-hr urinary protein-to-creatinine ratio at week 36. The trial results are being presented at the American Society of Nephrology Kidney Week 2026. The logo of the New England Journal of Medicine is at the bottom.
