Business Context and Reporting Period
This Current Report on Form 8-K was filed by Vera Therapeutics, Inc. on September 15, 2026.

Key Financial Metrics
The filing text does not provide specific financial data regarding revenue, profit, cash flow, margins, debt, or liquidity. This report focuses exclusively on clinical trial outcomes and regulatory disclosures.
Material Changes and Clinical Results
The Company announced that TRUTAKNA met all prespecified endpoints in the ORIGIN 3 trial involving 428 patients. Key results compared to placebo include:
- eGFR Change at 52 Weeks: TRUTAKNA showed a mean change of -0.1 mL/min/1.73m² versus -5.7 for placebo (Treatment effect: 5.6; p < 0.0001).
- Annualized eGFR Slope (104 weeks): TRUTAKNA showed a slope of -0.6 mL/min/1.73m²/year versus -5.6 for placebo (Treatment effect: 5.0; p < 0.0001).
- Kidney Disease Progression: TRUTAKNA demonstrated a 76% risk reduction in composite kidney disease progression events (Hazard ratio 0.24; p < 0.0001).
- Severe Outcomes: Zero patients in the TRUTAKNA group required dialysis, transplant, or died through 104 weeks, compared to 8 in the placebo group.
- Secondary Endpoints: Statistically significant reductions were achieved in proteinuria, galactose-deficient IgA1, and hematuria.
Outlook, Risks, and Safety Profile
TRUTAKNA was well tolerated with a safety profile generally comparable to placebo. Rates of overall adverse events and infections were similar between groups, with no opportunistic infections or clinically relevant hypogammaglobulinemia observed. The eGFR results align with KDIGO treatment goals to reduce kidney function decline to the physiologic rate (<1 mL/min/1.73m²/year). The filing includes standard forward-looking statement disclaimers regarding future regulatory approvals and commercialization.
