RUBY-3 (NCT05732402) – Phase 1b Glomerulonephritis Basket Study

RUBY-3 (NCT05732402) is a multiple ascending dose, multi-cohort, open label, phase 1b/2 study of povetacicept in autoimmune glomerulonephritis, including IgA nephropathy, primary membranous nephropathy, lupus nephritis, and renal ANCA-associated vasculitis, where povetacicept is being administered subcutaneously for up to 104 weeks. Key endpoints include proteinuria, eGFR, renal response, and disease-related autoantibodies.

Acazicolcept is a first-in-class dual inhibitor of the CD28 and ICOS T cell costimulatory pathways. The molecule is being developed for treatment of severe inflammatory diseases.

We are currently enrolling Synergy, a phase 2 study of acazicolcept in patients with Systemic Lupus Erythematosus (NCT04835441). This randomized, double-blind, placebo-controlled study was designed to evaluate the safety, tolerability, efficacy, immunogenicity, pharmacokinetics, and pharmacodynamics of acazicolcept.
