VERA Phase 3 ORIGIN: NEJM-published IgAN results with 42% UPCR drop
Rhea-AI Filing Summary
Vera Therapeutics (VERA) reported positive Phase 3 ORIGIN data for atacicept in IgA nephropathy, presented as a late-breaking oral at ASN Kidney Week 2025 and published in The New England Journal of Medicine. Participants on atacicept achieved a 46% reduction from baseline in proteinuria (24-hour UPCR) and a statistically significant, clinically meaningful 42% reduction versus placebo (p<0.0001) at week 36.
Efficacy was consistent across prespecified subgroups, including age, sex, race, region, baseline proteinuria, baseline eGFR, and baseline SGLT2i use. Secondary endpoints improved: Gd-IgA1 decreased by 68% and hematuria resolved in 81% of those with baseline hematuria. Safety across the ORIGIN program appears favorable and comparable to placebo, with fewer serious adverse events on atacicept (1 [0.5%]) than placebo (11 [5%]) and no deaths reported.
Positive
- Phase 3 efficacy and safety: 42% UPCR reduction vs placebo (p<0.0001), secondary endpoint improvements (68% Gd-IgA1 reduction; 81% hematuria resolution), and fewer serious adverse events vs placebo.
Negative
- None.
Insights
Phase 3 data show strong efficacy and favorable safety in IgAN.
Atacicept demonstrated robust proteinuria reduction in the ORIGIN Phase 3 trial: a 46% drop from baseline in 24-hour UPCR and a 42% reduction versus placebo at week 36 with p<0.0001. The company also reports consistent efficacy across prespecified subgroups, which supports generalizability within the studied population.
Key secondary measures moved in the right direction: Gd-IgA1 fell by 68% and hematuria resolved in 81% of participants with baseline hematuria. The safety profile “appears favorable,” with serious adverse events lower on atacicept (1 [0.5%]) versus placebo (11 [5%]) and no deaths, and no safety signals indicating immunosuppression in the excerpt.
The plenary slot at ASN Kidney Week and simultaneous NEJM publication suggest high scientific visibility. Actual regulatory and commercial outcomes will depend on full data packages and subsequent agency review; the excerpt does not provide timing for next steps.
