T cell epitope mapping of secukinumab and ixekizumab in healthy donors.

ABSTRACT: Secukinumab, a human monoclonal antibody that selectively neutralizes IL-17A, has consistently shown low anti-drug antibody responses in patients with psoriasis, psoriatic arthritis, and ankylosing spondylitis. Secukinumab has also shown lower in vitro immunogenicity potential compared with other monoclonal antibodies used to treat psoriasis and psoriatic arthritis, and a significantly lower in vitro T cell precursor frequency compared with ixekizumab, which targets the same antigen. Here, secukinumab and ixekizumab were further examined regarding their specific T cell epitopes. Secukinumab- or ixekizumab-specific CD4 T cell lines were generated from 31 healthy, treatment-naïve donors via 28-day co-culture with mature monocyte-derived dendritic cells exposed to either
