Compound class: Antibody
Comment: Teprotumumab is a fully human anti-insulin-like growth factor 1 receptor (IGF-1R) monoclonal antibody (antagonist) [2] that was originally developed in a collaboration between Genmab and Roche, and later licensed to Horizon Therapeutics who completed its advancement through clinical trials in thyroid eye disease. Heavy and light chain variable region peptide sequences for teprotumumab are 100% matches for SEQ IDs 1 and 2 (respectively) that are claimed in Hoffmann-La Roche patent WO2005005635A2 [4]. This patent claims two preferred antibodies, antibody 18 and antibody 22, but it is not clear which contains SEQ IDs 1 and 2.

Immunopharmacology Comments
Teprotumumab can be used as an alternative to corticosteroid or Th1 chemokine-targeting anti-inflammatory therapeutics to reduce the inflammation associated with Graves' ophthalmopathy. Fibroblasts in the connective tissues of the orbit have been identified as potential target cells in Graves' ophthalmopathy [1,3,6] and it is these fibroblasts that express teprotumumab's molecular target, IGF-1R.
