LBL-047, A First-In-Class Anti-BDCA2/TACI Fusion Protein, Inhibits the Function of Both pDCs and B cells [WITHDRAWN] (ACR Convergence 2025) - "Litifilimab, an anti-BDCA2 antibody, has demonstrated promising preliminary efficacy and excellent safety profile in patients with cutaneous lupus erythematosus...Targeting this pathway, two TACI based recombinant fusion proteins, such as Povetacicept and Telitacicept, have shown clinical benefits and favorable safety profile in autoimmune disease trials... LBL-047 has shown dual immunosuppressive effects, inhibiting simultaneously the function of pDCs and B cells both in vitro and in vivo. In addition, it has demonstrated excellent PK and PD profile, coupled with good safety profile and tolerability in cynomolgus monkeys. Taken together, these findings support the clinical development of LBL-047 and highlight its promise as a therapeutic candidate for autoimmune diseases."
