Anti-CD4 therapeutic antibody (Pre-made Keliximab biosimilar, Whole mAb) is a biosimilar expressed by mammalian cell line as a benchmark reference therapeutic antibody for biological drug disovery items including cell culture, assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic) and mechanism of action (MOA) research.
Izokibep has been specifically designed to utilize the strengths of Affibody’s technology platform to create a very small protein drug (18 kDa, approximately one eighth of the size of an antibody) with very high apparent affinity to IL-17A (KD ~300fM, approximately 1000X of a typical IL-17 antibody) and antibody-like half-life due to the strong (KD ~50pM) binding affinity to serum albumin. These features lead to the potential for best-in-class efficacy in a convenient, less frequent and at-home subcutaneous administration.
