About ATOR-1015
ATOR-1015 is a next generation CTLA-4 bispecific antibody developed for tumor-directed immunotherapy with increased capability of regulatory T-cell depletion. It is fully owned by Alligator. ATOR-1015 binds to two different immune receptors: the checkpoint receptor CTLA-4 and the co-stimulatory receptor OX40. The immune activation is increased in areas where both target molecules are expressed at high levels, notably in the tumor microenvironment, which is believed to reduce adverse immune reactions.
