Review Case ReportsTelitacicept for Recalcitrant Cutaneous Manifestations of Systemic Lupus Erythematosus: A Case Report and Review of the Literature.
Telitacicept is a novel humanized, recombinant transmembrane activator and calcium modulator and cyclophilin ligand interactor and the Fc portion (TACI-Fc) fusion protein, designed to neutralize the activity of both B-cell lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL). On March 9, 2021, telitacicept received its first approval in China for the treatment of adult patients with active, autoantibody-positive systemic lupus erythematosus (SLE). Additionally, on April 15, 2020, the U. ⋯ This is the first case that reports telitacicept successfully treated a SLE patient with refractory cutaneous involvement, which provides a potential therapeutic option for recalcitrant cutaneous manifestations of SLE. Furthermore, we review reported studies of BLyS targeted treatments for mucocutaneous lupus. Telitacicept appears to have activity in refractory cutaneous involvement of SLE and clinical trials are warranted to further assess this potential therapy.
