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.

Primary Endpoint: UPCR Reduction Interim Analysis Set (IAS) included the first 203 randomized participants who received ≥1 dose of trial drug. Change from baseline in natural-log transformed UPCR at Week 36 was analyzed using a mixed-effects model with repeated measurement (MMRM), including fixed effects for treatment group, visit as a categorical variable, treatment-by-visit interaction, baseline natural-log transformed UPCR, baseline eGFR category, SGLT2i use at baseline, and region, with participant as a random effect. log-transformed change from baseline in UPCR was estimated with use of least-squares means. To facilitate interpretation of the result, the least-squares means estimate was back-exponentiated to obtain the equivalent geometric mean percentage change. MMRM analysis included double-blind period data up to Week 36, regardless of treatment discontinuation or initiation of rescue treatment for IgAN or prohibited therapy; missing values after study withdrawal were imputed with jump to reference (placebo) approach for 100 times. The Rubin rule was used to combine results estimated from each of 100 imputation datasets by MMRM analysis.

Subgroup analyses were conducted using the same imputed data sets and the same MMRM model as for the primary analysis for each subgroup category, separately. If the subgroup was one of the covariates in the model, the covariate was removed from the model statement when the model was performed for the particular subgroup.

Missing data were handled implicitly by statistical model. Nominal p-values are presented. 1. Change from baseline in natural log-transformed Gd-IgA1 was analyzed using MMRM similar to that for the primary endpoint. 2. Percentages represent change from baseline in number of participants with hematuria (urine dipstick blood ≥1+) at each visit divided by number of participants with baseline hematuria shown on the lower axis; resolution defined as urine dipstick blood of trace or negative. Odds ratio is calculated from a logistic regression model adjusted for covariates. eGFR results not disclosed per FDA recommendation to sponsors of IgAN registrational trials

Atacicept: cholecystitis, determined by site investigator to be unrelated to treatment; Placebo (n=1 each): gastroenteritis, lower respiratory tract infection, pneumonia, pyelonephritis, IgA nephropathy, renal impairment, acute myocardial infarction, transplant rejection, hyponatremia, osteonecrosis, ovarian epithelial cancer, carotid artery aneurysm, hypertension, acute cholecystitis. 1 placebo serious adverse event was deemed related to study drug. Discontinuations in the 2 atacicept participants were due to eczema and erythema. Majority were mild to moderate injection site reactions that did not lead to discontinuation. Injection site reactions among atacicept recipients were largely characterized by injection site erythema, bruising, and pruritis. No observed hypogammaglobulinemia (IgG <3 g/dL).
