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 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.
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 developing 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 .
