[8-K] Vera Therapeutics, Inc. Reports Material Event

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

Biopharma clinical-trials analyst

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.

Item 8.01 Other Events

On November 6, 2025, Vera Therapeutics, Inc. (the “Company”) issued a press release announcing that data from the ORIGIN Phase 3 trial of atacicept in IgA nephropathy (“IgAN”) were presented as a featured late-breaking oral presentation during the opening plenary session of the American Society of Nephrology (“ASN”) Kidney Week 2025 and simultaneously published in The New England Journal of Medicine. The Company stated that participants treated with atacicept achieved a 46% reduction from baseline in proteinuria as measured by 24-hour urine protein-to-creatinine ratio (“UPCR”), with a statistically significant and clinically meaningful 42% reduction in UPCR compared to placebo (p<0.0001) at week 36. Proteinuria efficacy was consistent across prespecified subgroups of age, sex, race, region, baseline proteinuria, baseline eGFR, and baseline SGLT2i use. Atacicept treatment also led to improvements in secondary endpoints: Gd-IgA1 was reduced by 68% and hematuria was resolved in 81% of participants with baseline hematuria.

Across the ORIGIN program in IgAN, the safety profile of atacicept appears favorable, and comparable to placebo. In the ORIGIN 3 full analysis set, the incidence of adverse events was generally balanced between the atacicept and placebo groups, with fewer serious adverse events reported with atacicept (n=1 [0.5%]) than placebo (n=11 [5%]), and no safety signals indicating immunosuppression. There were no deaths in either treatment group. In connection with the press release and presentation at ASN, the Company compiled a corporate presentation (the “Presentation”) that includes slides with the data referenced above. The slides that reflect the above data and which are included in the Presentation are filed as Exhibit 99.1 hereto.
