| Open AccessCancer immune therapy with PD-1-dependent CD137 co-stimulation provides localized tumour killing without systemic toxicity
The toxicity arising from generalised stimulation of T cells restricts applicability of CD137 agonists in cancer immune therapy. Here authors show that a bispecific antibody blocking PD-1 while activating CD137 efficiently restricts T cell activation to the tumour microenvironment, resulting in efficient tumour control and reduced liver toxicity.
