The present invention provides ICOSL specific antigen binding molecules which are isolated from immunized and synthetic Elasmobranchii derived libraries. In particular, the present invention relates to shark Variable New Antigen Receptor (VNAR) domains that specifically bind and neutralize the activity of human Induced Co-Stimulatory Ligand (ICOSL). The neutralizing VNAR domains are isolated from two independent sources; an immunized nurse shark library and a synthetic spiny dogfish framework fusion library. The molecules may be formulated as pharmaceutical compositions and used in medicine.
