Whether dual inhibition APRIL/BAFF offers a longer-term advantage over APRIL-selective therapy remains a key question that only eGFR slope data will answer. APRIL-selective therapy also prevents its action at other receptors (BCMA).
Do you think either has the advantage?

In VISIONARY, APRIL-selective B-cell inhibition ⬇️proteinuria & IgA-related biomarkers, confirming APRIL’s key pathogenic role.
In ORIGIN-3, atacicept’s BAFF + APRIL blockade targets earlier B-cell checkpoints, dismantling both the production & maintenance of aberrant IgA response.

The emerging evidence from APRIL/BAFF–axis trials (including VISIONARY (sibeprenlimab) & ORIGIN-3 (atacicept)) highlight how central this pathway is to the mechanisms of IgAN.

1° Endpoint
At week 36- 🗓️
📉Atacicept: 24-hour urinary protein-to-creatinine ratio decreased by 45.7%
🔻Placebo: 24-hour urinary protein-to-creatinine ratio decreased by 6.8%

Although both BAFF and APRIL are responsible for B-cell proliferation, survival/maturation, and class switching they affect different stages of B cell maturation.

Mechanistic lead-in came from the JANUS ph2 study (N=16):
👉 dose-dependent reductions in IgA, IgG, IgM, and Gd-IgA1 by week 24
👉maintained through week 72
👍 concurrent proteinuria improvement and preserved eGFR

The ORIGIN phase 2b trial
👥 116 patients with biopsy-proven IgAN and persistent proteinuria despite RASi
💉 Weekly atacicept 150 mg (wk 36)
⬆️ 35% greater UPCR reduction vs placebo
⚙️ a mean eGFR benefit of +5.8 mL/min/1.73 m²

The 96-week extension demonstrated durability:
⬇️proteinuria fell 52%
⬇️Gd-IgA1 dropped 66%
⬇️hematuria declined 75%
⬇️ annualized eGFR slope was −0.6 mL/min/1.73 m²
⚠️Safety: mild injection-site reactions and transient infections

🛑Remission is defined an eGFR decline of ~1 ml/min/1.73 m²/year, closer to physiological rate
📉Vs 2-3 ml per year with only conservative therapy; hopefully, B-cell therapies will further flatten the slope

Remember 2021, and the first glomerulonephritis @kdigo.org guidelines for IgAN? Only RASi and steroids were viable treatment options. However, it seems in 2025 we have so many other options, no?

We are discussing ORIGIN3 and atacicept in IgAN.
APRIL, BAFF and B-cells, Oh My! (🦁🐯🐻)
It's going to be Wicked good. 🧙♀️ #NephJC

Join us today to learn more on the recent (And first ever disease specific) evidence based KDIGO IgA Nephropathy guidelines.
There’s still time to review the highlights before the discussion.
