Long-term improvements observed in the quartet of findings defining disease modification supports atacicept’s potential to prevent kidney failure in patients with IgAN;Long-term results from the ORIGIN Phase 2b study were simultaneously published in the Journal of the American Society of Nephrology;Company will host an investor call and webcast on Monday October 28 at 8:00 AM ET BRISBANE, Calif., Oct. 26, 2024 (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 announced data from its ORIGIN Phase 2b trial of atacicept in immunoglobulin A nephropathy (IgAN) that show stabilized kidney function through 96 weeks of long-term follow-up. These data were presented in a late-breaking oral presentation at the American Society of Nephrology Kidney Week 2024 in San Diego, California, and simultaneously published in a manuscript in the Journal of the American Society of Nephrology. “The 96-week results from the ORIGIN Phase 2b study demonstrated sustained and substantial reductions in Gd-IgA1, hematuria and proteinuria as measured by UPCR with long-term stabilization of eGFR,” said Jonathan Barratt, MD, PhD, FRCP, Mayer Professor of Renal Medicine at the University of Leicester. “Converting patients with IgAN from an eGFR profile of unrelenting decline to a profile consistent with the general population without kidney disease is a differentiated and compelling finding. Collectively, the data support the potential of atacicept to modify the natural history of the disease and prevent kidney failure during the lifetime of patients with IgAN.” “We are excited to present these long-term efficacy and safety data from the ORIGIN Phase 2b study, which further demonstrate atacicept’s potential to address the underlying pathogenesis of IgAN. The stabilization of kidney function through two years—the longest duration of data among B cell modulators to date—positions atacicept as a potential best- and first-in-class treatment option for patients with IgAN,” said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. “We look forward to announcing expected topline results from the Phase 3 ORIGIN 3 trial in Q2 2025, with planned BLA submission to the U.S. FDA later in the year.” Over 96 weeks, participants treated with atacicept demonstrated a -66% reduction in galactose-deficient IgA1 (Gd-IgA1), resolution of hematuria in 75% of participants, a -52% reduction in proteinuria, and a mean annualized estimated glomerular filtration rate (eGFR) slope of -0.6 mL/min/1.73m2/year. The cumulative generally favorable safety profile of atacicept remained consistent with that observed during the randomized period, with a 90% completion rate of atacicept treatment. Figure 1. ORIGIN Phase 2b long-term 96-week results with atacicept was consistent with disease-modifying IgAN profile The Company believes these data support the potential for atacicept to offer long-term, comprehensive IgAN disease modification and provide further confidence in the ongoing pivotal Phase 3 ORIGIN 3 trial of atacicept in IgAN. The Company will host an investor call and webcast to discuss the data update on Monday, October 28, at 8:00 AM ET. The live webcast will be available on the Company’s Investor Calendar at https://ir.veratx.com/news-events/investor-calendar, with the recording and presentation available immediately following the event. The Kidney Week 2024 presentation and posters are available on the Company’s website at https://ir.veratx.com/news-events/presentations. Upcoming milestones: ORIGIN Extend – plan to initiate a study in Q4 2024 that will provide ORIGIN participants with extended access to atacicept prior to commercial availability in their region, as well as an opportunity to capture longer-term data.Pivotal ORIGIN 3 trial on track to announce topline results in Q2 2025, with planned BLA submission to the U.S. FDA later in the yearPIONEER Study – plan to initiate a study in 2025 that will evaluate the efficacy and safety of atacicept in: Expanded IgAN populations – The first set of cohorts will include adults with low kidney function (eGFR 20 to <30 mL/min/1.73 m2), low (UPCR <1.0 g/g) or high proteinuria (UPCR ≥5.0 g/g) or IgAN recurrence after kidney transplant; adolescents at high risk of progression (UPCR ≥0.3 g/g); as well as adolescents and adults with IgA vasculitis nephritis.Anti-PLA2R and anti-nephrin podocytopathies – The PIONEER study will expand to additional autoimmune glomerular diseases characterized by the presence of antibodies to glomerular antigens, including primary membranous nephropathy, focal segmental glomerulosclerosis, and minimal change disease. About the Phase 2b ORIGIN clinical trialThe Phase 2b ORIGIN clinical trial (NCT04716231) is a global, multicenter, randomized, double-blind, placebo-controlled trial evaluating the safety and efficacy of atacicept in 116 patients with IgAN who continue to have persistent proteinuria and remain at high risk of disease progression despite being on a stable prescribed regimen of a renin-angiotensin-aldosterone system inhibitor for at least 12 weeks that is the maximum labeled or tolerated dose. The Phase 2b ORIGIN clinical trial evaluated three dose strengths of atacicept versus placebo, administered weekly by prefilled syringe. Patients were randomized 2:2:1:2 to atacicept 150 mg, atacicept 75 mg, atacicept 25 mg or matching placebo. Upon completion of the 36-week blinded treatment period, all patients were offered open-label atacicept 150 mg for an additional 60 weeks. The primary endpoint was the change in proteinuria as evaluated by urine protein to creatinine ratio (UPCR) at week 24, and the key secondary endpoint was the change in proteinuria as evaluated by UPCR at week 36. Additional exploratory endpoints include change in proteinuria as evaluated by UPCR at weeks 12, 48, and 96; change in eGFR; change in serum immunoglobulin levels, and change in serum Gd-IgA1 levels; safety and tolerability; and serum pharmacokinetics. The trial met its primary and key secondary endpoints, with statistically significant and clinically meaningful proteinuria reductions and stabilization of eGFR versus placebo through week 36. The safety profile was comparable between atacicept and placebo. For more information about the Phase 2b ORIGIN clinical trial, please visit www.clinicaltrials.gov. About the Phase 3 ORIGIN 3 clinical trialThe ORIGIN 3 clinical trial (NCT04716231) is a global, multicenter, randomized, double-blind, placebo-controlled Phase 3 trial evaluating the safety and efficacy of atacicept in patients with IgAN who continue to have persistent proteinuria and remain at high risk of disease progression despite being on a stable prescribed regimen of renin-angiotensin system inhibitors for at least 12 weeks that is the maximum labeled or tolerated dose. The objectives of the trial are to determine the effect of atacicept on proteinuria and preservation of kidney function compared to placebo. For more information about the ORIGIN 3 clinical trial, please visit http://www.clinicaltrials.gov. About AtaciceptAtacicept is an investigational recombinant fusion protein that contains the soluble transmembrane activator and calcium-modulating cyclophilin ligand interactor 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 certain autoimmune diseases, including IgAN and lupus nephritis. The Phase 2b ORIGIN 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 72 weeks, atacicept demonstrated further reductions in Gd-IgA1, hematuria and proteinuria, as well as stabilization of eGFR reflecting a profile consistent with that of the general population without IgAN. 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 Phase 2b ORIGIN clinical trial, atacicept may demonstrate substantial improvement on a clinically significant endpoint over available therapies for patients with IgAN. Vera believes atacicept is positioned for best-in-class potential, targeting B cells and plasma cells to reduce autoantibodies and having been administered to more than 1,500 patients in clinical studies across different indications.

(Nasdaq: CLYM), will be hosting a virtual investor event, today, October 15, 2024, from 12:00 p.m. to 2:00 p.m. ET. The event will feature members of Climb Bio’s management team who will provide an update on the Company’s development strategy for budoprutug, an anti-CD19 monoclonal antibody with potential to treat a broad range of B-cell mediated diseases. The event will also feature Dr. Frank Cortazar, Director of the New York Vasculitis and Glomerular Center and Chief of Clinical Research at St. Peter's Health Partners, who was the primary investigator in the Phase 1b trial of budoprutug in pMN. Dr. Cortazar will present additional data from the completed pMN trial and share clinical data from a single patient with Minimal Change Disease (MCD) treated with budoprutug. “Our mission at Climb Bio is to develop better treatments for the approximately 50 million patients in the U.S. and many more globally living with immune-mediated diseases,” said Aoife Brennan, President and CEO of Climb Bio. “We are off to a great start with some world class talent and a cornerstone asset, budoprutug. We believe CD19 is the optimal target for B-cell mediated diseases and that an antibody is the modality with the broadest potential to help patients. We are thrilled today to share our development strategy and promising preclinical and clinical data that underscore our enthusiasm for budoprutug’s potential.” Dr. Cortazar added, “I know firsthand the challenges of managing patients with pMN and the need for new treatment options. The patients in the pMN trial demonstrated high rates of complete clinical remission, as well as rapid reductions in B-cells and anti-PLA2R antibodies, two key biomarkers for pMN. These data potentially support a significant advancement in our fight against this challenging condition, and I am hopeful to continue to help advance this innovative therapy for those in need.” Event Highlights Rational and data driven clinical development strategy The Company’s strategic approach to developing budoprutug will consider indications across three opportunity sets, including; IgG4-mediated diseases, such as pMN;Diseases caused by IgG1-3 that impact a single organ system, such as ITP; andComplex systemic diseases, such as SLE. Budoprutug is a differentiated anti-CD19 monoclonal antibody with potential for potent B-cell depletion The Company will share data supporting budoprutug’s potential for deep and durable depletion of both peripheral and tissue-resident B-cells in patients with immune-mediated diseases In a transgenic mouse model expressing human CD19, budoprutug achieved dose-dependent B-cell depletion in bone marrow, lymph nodes, and spleen.Doses as low as 100 mg induced B-cell depletion to undetectable levels in pMN patients treated with budoprutug. Continued advancement of subcutaneous formulation of budoprutug Budoprutug has been successfully formulated above 175 mg/ml while maintaining low viscosity, creating an opportunity to pursue a subcutaneous dosing form that potentially features a low volume injection.The Company plans to continue to advance the subcutaneous formulation clinical program, with non-clinical data expected in the first half of 2025. Additional promising Phase 1b Study Results in pMN Dr. Frank Cortazar, Director of the New York Nephrology Vasculitis and Glomerular Center, will present additional data from the Phase 1b study of budoprutug in patients with pMN.The study demonstrated the following for the 5 patients who received all 4 doses of budoprutug: Complete remission of proteinuria achieved by 3/5 (60%) of patients.Rapid and significant reductions in anti-PLA2R autoantibodies, a key driver of pMN, with serological remission occurring in the 3 patients that were PLA2R positive at baseline.Complete and sustained B-cell depletion was observed in all patients, with undetectable levels of B-cells occurring after just two doses of study drug as low as 100 mg.Budoprutug was generally well-tolerated, with no reported drug-related serious adverse events. Full data from this study will be presented in a poster presentation on October 24th at the American Society of Nephrology’s Kidney Week 2024 being held in San Diego, CA.Dr. Cortazar will also share data from a single patient trial for MCD showing the MCD patient was able to fully taper steroid and remains in complete remission 18 months following final administration of budoprutug, given as 4 doses over 6 months, 600mg cumulative dose. Initiation of Phase 1b clinical trial in SLE planned for the first half of 2025, subject to regulatory clearance SLE is a complex, chronic systemic disease opportunity affecting multiple organ systems, leading to significant morbidity and mortality that affects approximately 200,000 to 300,000 people in the U.S.Design of Phase 1b trial in SLE: An open-label trial in patients with active lupus is planned.Endpoints will include clinical response, decline in pathogenic autoantibodies, and assessment of B-cell subsets upon recovery.The trial will utilize informative serum biomarkers to accelerate proof-of-concept, optimize dosing, and benchmark against other B-cell depleting therapies. Initiation of Phase 2 clinical trial in ITP planned for the first half of 2025, subject to regulatory clearance ITP is an IgG 1-3 immune-mediated disorder affecting an estimated 60,000 adults in the U.S. and where there is compelling proof-of-concept validating the clinical rationale for using B-cell depletion therapies.Design of Phase 2 trial in ITP: Single-arm, open-label study in adult patients with chronic ITP is planned.Primary endpoint will measure platelet improvement along with other disease parameters.A unique "treat-to-target" approach is included in the study protocol to allow for personalized redosing based on individual patient needs. Corporate Update and Upcoming Milestones As of September 30, 2024, the Company had cash, cash equivalents and marketable securities of approximately $218 million, which is expected to fund operations through 2027.Initiation of clinical trials in SLE and ITP with first patients dosed targeted for the first half of 2025, subject to regulatory clearance.Advancement of subcutaneous formulation clinical program, with non-clinical data expected in the first half of 2025.Advancement of pMN clinical program to late phase development expected in 2025.

PIONEER study expands the investigation of atacicept into a broad definition of IgA nephropathy and into multiple autoimmune glomerular diseases, supported by the disease-modifying potential of BAFF/APRIL dual inhibition;Multiple regulatory and clinical milestones expected over the next 18 months; Announcements made at Vera’s R&D Day in New York, where the company’s management team was joined by academic leaders Jonathan Barratt, Richard Lafayette, and Brad Rovin BRISBANE, Calif., Oct. 02, 2024 (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 announced expansion of its development pipeline for its lead asset, atacicept. This program is expected to build on the positive data reported to date from the ongoing ORIGIN Phase 2b and 3 clinical program developing atacicept to treat patients with IgAN, by extending into a broader population of IgAN and other autoimmune kidney indications. “Based on the positive clinical data announced over the past year, we have a greater understanding of atacicept’s disease-modifying mechanism of action and potential to be a best-in-class treatment option for patients with IgAN. We’re committed to providing long-term access to atacicept for all ORIGIN participants, and the PIONEER study will expand that opportunity to a significantly greater number of patients with IgAN,” said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. “We believe that B cell modulation through BAFF/APRIL dual inhibition has the potential to transform the treatment landscape for other autoimmune diseases, including autoimmune forms of primary membranous nephropathy, focal segmental glomerulosclerosis, and minimal change disease.” “We view this expansion of our pipeline as highly complementary to our lead program in IgAN. As such, we remain focused on completing the pivotal clinical program for atacicept in IgAN. We look forward to keeping everyone apprised of our progress, as we have a number of significant milestones planned across our pipeline,” concluded Dr. Fordyce. ORIGIN Extend – The company plans to initiate a study in Q4 2024 that will provide ORIGIN participants with extended access to atacicept prior to commercial availability in their region, as well as an opportunity to capture longer-term data. PIONEER Study – In 2025, the company plans to initiate a study evaluating the efficacy and safety of atacicept in: Expanded IgAN populations – The first set of cohorts will include adults with low kidney function (eGFR 20 to <30 mL/min/1.73 m2), low (UPCR <1.0 g/g) or high proteinuria (UPCR ≥5.0 g/g), or IgAN recurrence after kidney transplant; adolescents at high risk of progression (UPCR ≥0.3 g/g); as well as adolescents and adults with IgA vasculitis nephritis.Anti-PLA2R and anti-nephrin podocytopathies – The PIONEER study will expand to additional autoimmune glomerular diseases characterized by the presence of antibodies to glomerular antigens, including primary membranous nephropathy (pMN), focal segmental glomerulosclerosis (FSGS), and minimal change disease (MCD). These new indications represent a significant potential opportunity for atacicept, with the combined peak prevalence of IgAN and autoimmune-driven PMN, FSGS, and MCD in the US estimated at ~230,000. The company believes atacicept may have therapeutic potential in additional rheumatologic and hematologic indications. Vera’s management team was joined by Jonathan Barratt, MD, PhD, FRCP (University of Leicester), Richard Lafayette, MD, FACP (Stanford University Medical Center), and Brad Rovin, MD, FACP, FASN (Ohio State University Wexner Medical Center). A replay of the event is available on the Investor Calendar of the company’s website at https://ir.veratx.com or (click here). The R&D Day event was held in advance of the anticipated 96-week data from the Phase 2b ORIGIN study of atacicept in IgAN, which will be presented as a late-breaking oral presentation at the American Society of Nephrology Kidney Week 2024.
