Comment: Voclosporin (ISA247, ISATX247) is a cyclic peptide that is a semi-synthetic cyclosporine analogue [1-3,6], but with distinct clinical efficacy and safety profiles [5]. Like cyclosporine, it has immunosuppressive action, and it binds cyclophilin A [4]. Functionally, it acts as a calcineurin inhibitor. Prior to voclosporin, clinically used calcineurin inhibitors were cyclosporine (cyclosporin A), tacrolimus, and pimecrolimus.
