Compound class: Antibody
Comment: Ozoralizumab is a trivalent albumin-binding nanobody that binds to and neutralises circulating TNFα. This biologic agent is being investigated for anti-inflammatory potential. The peptide sequence for ozoralizumab submitted in its WHO INN record is identical to SEQ ID NO: 96 (TNF30) in patent US8703131 [1], and identifies the albumin nanobody as ALB8. The patent claims a trivalent construct of TNF30-linker-ALB8-linker-TNF30.
Bioactivity Comments
Ozoralizumab binds serum albumin, in addition to TNFα, an action that increases its in vivo half-life [2].
