BRISBANE, Calif., Feb. 26, 2026 (GLOBE NEWSWIRE) -- Vera Therapeutics, Inc. (Nasdaq: VERA), a late clinical-stage biotechnology company focused on developing and commercializing transformative treatments for patients with serious immunological diseases, today reported its business highlights and financial results for the full year ended December 31, 2025.

"In 2025, Vera Therapeutics delivered on several key milestones as we advanced atacicept toward potential FDA approval and commercialization," said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. "The BLA has been granted priority review and we expect to be commercially prepared to successfully launch atacicept in IgAN in mid-2026 if approved. Our commercial team brings decades of experience launching innovative therapies and is eager to bring this potentially disease-modifying therapy to patients with IgAN and other autoimmune kidney diseases."

"Vera Therapeutics has established a leadership position within the IgAN space based on the compelling profile of atacicept. Data from the ORIGIN clinical program have shown that blocking BAFF and APRIL with atacicept results in clinically meaningful reductions to proteinuria, Gd-IgA1, and hematuria (Phase 2 and 3) and a stabilization of eGFR (Phase 2)," said Robert M. Brenner, M.D., Chief Medical Officer of Vera Therapeutics. "Vera is confident in the strength of the atacicept data package to support approval and deliver a potential new therapy to the IgAN patients and caregivers whom we serve."

Key Full Year 2025 and Recent Business Highlights

   -- Positive primary endpoint results from the ORIGIN Phase 3 clinical trial 
      of atacicept for the treatment of IgAN were presented in a featured 
      late-breaking oral presentation during the opening plenary session of ASN 
      Kidney Week 2025 and published in the New England Journal of Medicine 
 
   -- FDA granted priority review to the atacicept BLA for the treatment of 
      IgAN in adults, and assigned a PDUFA target action date of July 7, 2026; 
      Vera Therapeutics plans for a potential commercial launch in mid-2026 
 
   -- Matt Skelton, Chief Commercial Officer, advancing preparations for U.S. 
      commercial launch 
 
   -- Appointed James R. Meyers, an accomplished biopharmaceutical executive 
      with over three decades of commercial leadership experience, to Board of 
      Directors 
 
   -- Successfully completed an equity financing and entered into a debt 
      agreement resulting in combined potential gross proceeds of $800 million, 
      strengthening Vera Therapeutics' balance sheet to fund operations beyond 
      the potential approval and U.S. commercial launch of atacicept 

Anticipated Upcoming Milestones

   -- Potential FDA approval of atacicept in IgAN -- PDUFA date of July 7, 2026 
 
   -- Planned U.S. commercial launch of atacicept, pending FDA approval -- 
      mid-2026 
 
   -- Initial results from PIONEER -- a Phase 2 basket trial evaluating 
      atacicept in expanded IgAN populations, and other autoimmune kidney 
      diseases -- expected in 1H 2026 
 
   -- Pivotal ORIGIN 3 study completion with two-year eGFR data -- expected in 
      2027 

Financial Results for the Year Ended December 31, 2025

For the year ended December 31, 2025, Vera Therapeutics reported a net loss of $299.6 million, or a net loss per diluted share of $4.66, compared to a net loss of $152.1 million, or a net loss per diluted share of $2.75, for the year ended December 31, 2024.

During the year ended December 31, 2025, net cash used in operating activities was $241.1 million, compared to $134.7 million for the year ended December 31, 2024.

Vera Therapeutics reported $714.6 million in cash, cash equivalents, and marketable securities as of December 31, 2025, which combined with availability under its debt facility, Vera Therapeutics believes to be sufficient to fund operations through potential approval and U.S. commercial launch of atacicept and beyond.

About Atacicept

Atacicept is an investigational recombinant fusion protein that contains the soluble transmembrane activator and calcium-modulating cyclophilin ligand interactor $(TACI)$ receptor that binds to the cytokines B-cell activating factor (BAFF) and A PRoliferation-Inducing Ligand (APRIL). These cytokines are members of the tumor necrosis factor family that promote B-cell survival and autoantibody production associated with IgAN, lupus nephritis, and other autoimmune kidney diseases.

About the Atacicept Clinical Program

The ORIGIN Phase 2b clinical trial of atacicept in IgAN met its primary and key secondary endpoints, with statistically significant and clinically meaningful proteinuria reductions and stabilization of eGFR versus placebo through 36 weeks. The safety profile during the randomized period was comparable between atacicept and placebo. Through 96 weeks, atacicept demonstrated further improvements in Gd-IgA1, hematuria, and proteinuria, as well as stabilization of eGFR reflecting a profile consistent with that of the general population without IgAN.

The ORIGIN Phase 3 trial met the primary endpoint with a statistically significant and clinically meaningful reduction in proteinuria at week 36, in the prespecified interim analysis. Across the ORIGIN program in IgAN, the safety profile of atacicept appears favorable, and comparable to placebo. The trial continues in a placebo-controlled blinded manner to evaluate the change in kidney function over two years as measured by eGFR, with results expected in 2027. For more information about ORIGIN 3, please visit http://www.clinicaltrials.gov.

Atacicept has received FDA Breakthrough Therapy Designation for the treatment of IgAN, which reflects the FDA's determination that, based on an assessment of data from the ORIGIN Phase 2b clinical trial, atacicept may demonstrate substantial improvement on a clinically significant endpoint over available therapies for patients with IgAN. Vera Therapeutics believes atacicept is positioned for best-in-class potential, targeting B cells to reduce autoantibodies and having been administered to more than 1,500 patients in clinical trials across different disease areas.

The ORIGIN Extend study provides ORIGIN study participants with extended access to atacicept until its potential commercial availability in their region and captures longer-term safety and efficacy data. Atacicept is also being evaluated in expanded IgAN populations, anti-PLA2R positive primary membranous nephropathy, and anti-nephrin positive focal segmental glomerulosclerosis $(FSGS)$ and minimal change disease $(MCD)$ patients in the PIONEER trial.

About Vera Therapeutics

Vera Therapeutics is a late clinical-stage biotechnology company focused on developing treatments for serious immunological diseases. Vera Therapeutics' mission is to advance treatments that target the source of disease in order to change the standard of care for patients. Vera Therapeutics' lead product candidate is atacicept, a fusion protein self-administered at home as a subcutaneous once weekly injection that blocks both BAFF and APRIL, which stimulate B cells to produce autoantibodies contributing to certain autoimmune diseases, including IgAN and lupus nephritis. Beyond IgAN, Vera Therapeutics is evaluating additional diseases where the reduction of autoantibodies by atacicept may prove clinically meaningful. In addition, Vera Therapeutics holds an exclusive license agreement with Stanford University for a novel, next generation fusion protein targeting BAFF and APRIL, known as VT-109, with wide therapeutic potential across the spectrum of B-cell-mediated diseases. Vera Therapeutics is also evaluating development of MAU868, a monoclonal antibody designed to neutralize infection with BK virus, which can have devastating consequences in kidney transplant recipients. Vera Therapeutics retains all global developmental and commercial rights to atacicept, VT-109 and MAU868. For more information, please visit www.veratx.com.
