TRUTAKNA, the first and only FDA-approved BAFF and APRIL inhibitor, met all prespecified endpoints, including unprecedented placebo-adjusted estimated glomerular filtration rate (eGFR) and composite kidney disease progression benefits.
Favorable safety profile, and generally comparable to placebo.
Strong commercial launch momentum with over 350 patient start forms generated in the first ten weeks.
Plan to submit supplemental BLA to the U.S. Food and Drug Administration (FDA) for full approval in Q4 2026.

BRISBANE, Calif., Sept. 15, 2026 (GLOBE NEWSWIRE) -- Vera Therapeutics, Inc. (Nasdaq: VERA), a commercial-stage biotechnology company, today announced that TRUTAKNA met all prespecified endpoints of the final efficacy analysis of the ORIGIN 3 trial in adults with primary IgA nephropathy (IgAN) at risk for disease progression. Topline results from the final analysis set of 428 patients are presented below.

	TRUTAKNA	Placebo	Treatment effect	p-value
Mean eGFR change from baseline at 52 weeks, mL/min/1.73m²	-0.1 (95% CI -1.4, 1.2)	-5.7 (95% CI -7.0, -4.4)	5.6 (95% CI 3.7, 7.5)	<0.0001
Annualized eGFR slope through 104 weeks, mL/min/1.73m²/year	-0.6 (95% CI -1.6, 0.4)	-5.6 (95% CI -6.6, -4.6)	5.0 (95% CI 3.6, 6.5)	<0.0001
Composite kidney disease progression event through 104 weeks, n	11	38	Hazard ratio 0.24 (95% CI 0.12, 0.48) 76% risk reduction	<0.0001
Dialysis ≥30 days, transplant, or death through 104 weeks, n	0	8

These eGFR results align with the KDIGO treatment goal to reduce the rate of kidney function decline to the physiologic rate (<1 mL/min/1.73m²/year).¹ TRUTAKNA also achieved statistically significant reductions in the hierarchically tested endpoints of proteinuria, galactose-deficient IgA1 (Gd-IgA1), and hematuria. TRUTAKNA was well tolerated with a favorable safety profile generally comparable to placebo, consistent with previous results from the ORIGIN program.² Rates of overall adverse events and infections or infestations were similar between the TRUTAKNA and placebo groups, and there were no opportunistic infections or clinically relevant hypogammaglobulinemia. Detailed results from the final efficacy analysis will be shared at an upcoming scientific congress.

“The ORIGIN 3 final analysis, demonstrating a significant reduction in risk of composite kidney disease progression, true stabilization of eGFR, and a favorable safety profile through two years, marks a milestone in IgAN treatment,” said Richard Lafayette, M.D., F.A.C.P., Professor of Medicine, Nephrology and Director of the Glomerular Disease Center at Stanford University Medical Center, and a principal investigator for ORIGIN 3. “Prevention of kidney failure or kidney-related death is the ultimate goal. We now have evidence suggesting that TRUTAKNA may help patients avoid dialysis, transplantation, or kidney-related death over the long term.”

“We believe that upstream inhibition of BAFF and APRIL with TRUTAKNA achieves results that reflect the potential for comprehensive disease modification in IgAN. ORIGIN 3 is the first reported Phase 3 IgAN trial to reach alignment with the FDA on an earlier final efficacy analysis, offering patients randomized to placebo an earlier opportunity to transition to open-label TRUTAKNA. The final results support this alignment and we plan to submit the supplemental BLA in the fourth quarter of this year. We look forward to the potential full approval of TRUTAKNA in 2027,” said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. “We reiterate our gratitude to the patients, investigators, employees, and collaborators who have helped us to deliver a transformative therapy to patients in need.”

“We are excited for the upcoming supplemental BLA submission based on the ORIGIN 3 final analysis. Since receiving accelerated approval, we have seen significant interest from the IgAN community. In the first ten weeks, we have generated over 350 patient start forms. We are seeing paid claims and are pleased with initial payer policies. The early momentum of the TRUTAKNA launch is very encouraging,” said Matt Skelton, Chief Commercial Officer of Vera Therapeutics.

About IgAN

IgAN is a serious, progressive, immune-mediated kidney disease and a leading cause of chronic kidney disease and kidney failure worldwide.^3,4 Approximately 2.5 adults per 100,000 worldwide are diagnosed with IgAN each year, most often between 30 and 40 years of age.^5,6 Over time, IgAN can lead to irreversible kidney damage and may ultimately require dialysis or kidney transplantation. At least 50% of patients may progress to kidney failure or death within 10 to 20 years of diagnosis.⁴

About TRUTAKNA (atacicept-vymj)

TRUTAKNA, a B-cell activating factor (BAFF) and A proliferation-inducing ligand (APRIL) inhibitor, is a soluble recombinant fusion protein containing the human transmembrane activator and calcium-modulating cyclophilin ligand interactor (TACI) receptor that binds to the cytokines BAFF and APRIL.⁷ BAFF and APRIL are key cytokines that activate B cells and drive IgAN pathophysiology. In IgAN, activated B cells produce both the antigen and associated antibodies that result in the production of damaging IgA immune complexes. The overlapping roles of BAFF and APRIL in activating B cells support the potential for TRUTAKNA as a disease-modifying therapy.³ TRUTAKNA is self-administered as an at-home, small-volume (1 ml), 150 mg once-weekly autoinjector.

Indication

TRUTAKNA (atacicept-vymj) is indicated to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk for disease progression.

This indication is approved under accelerated approval based on reduction of proteinuria. It has not been established whether TRUTAKNA slows kidney function decline over the long-term in patients with IgAN. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial.

Important Safety Information

Contraindications: TRUTAKNA is contraindicated in patients with serious hypersensitivity to atacicept-vymj or any excipients of TRUTAKNA.

Warnings and Precautions

Immunosuppression and Increased Risk of Infections: TRUTAKNA suppresses the immune system by reducing antibody production, which may increase the risk of infections. Patients with chronic infection or recurring infections may have an increased risk of serious infection. In clinical trials, infections were reported in 32% of TRUTAKNA patients compared with 28% of placebo patients.

Before initiating TRUTAKNA, assess patients for active infections. Delay TRUTAKNA administration in patients with active infection until the infection resolves or is adequately treated. Monitor patients for signs and symptoms of infection during treatment with TRUTAKNA. If a serious infection develops, consider interrupting TRUTAKNA until the infection is controlled.

The concomitant use of TRUTAKNA and other immune-modulating therapies has not been evaluated. Concomitant use of TRUTAKNA with drugs that affect the immune system, including systemic corticosteroids, may increase the risk of infection.

Immunosuppression and Immunization Risk: TRUTAKNA may interfere with the immune response to vaccines and increase the risk of infection from live vaccines. Prior to initiating treatment with TRUTAKNA, complete all age-appropriate immunizations. Live vaccines are not recommended within 30 days prior to initiation or during treatment with TRUTAKNA as safety of coadministration has not been established.

Adverse Reactions: The most common adverse reactions (≥5%) in patients treated with TRUTAKNA and placebo, respectively, were infections (32% vs 28%) and local administration reactions (30% vs 5%). The most common infection was upper respiratory tract infection (12% vs 9%), and the most common local administration reactions were injection site reaction (19% vs 2%) and injection site erythema (6% vs 1%).

Use in Specific Populations

Pregnancy: Available data on TRUTAKNA used in pregnant women exposed during clinical trials are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.

Based on the mechanism of action, TRUTAKNA may cause immunosuppression in the in utero-exposed infant. Consider the potential clinical impact of TRUTAKNA exposure in infants exposed in utero. Pregnant women exposed to TRUTAKNA, or their healthcare provider, should report TRUTAKNA exposure by calling 1-833-633-8372.

Pediatric Use: The safety and effectiveness of TRUTAKNA in pediatric patients have not been established.
