ATOR-1015 is a human bispecific antibody targeting CTLA-4 and OX40. It was developed by fusing an optimized version of CD86, one of the natural ligands to CTLA-4, to an agonistic OX40 antibody in an IgG1 format. Both CTLA-4, a checkpoint receptor expressed on regulatory T cells, and OX40, a co-stimulatory receptor on the T cells, are highly upregulated in the tumor microenvironment. So, by targeting these two receptors, ATOR-1015 has the potential to increase localization to the tumor area compared to monospecific antibodies.

The tumor localization of ATOR-1015 may reduce the risk of systemic T-cell activation and improve the efficacy. The mode of action of ATOR-1015 has been evaluated in vitro where it induces T-cell activation and depletes
