Bioactivity Comments
ALT-803 promotes immune activation with anti-tumour activity against relapsed hematological malignancies in humans [1]. It has been shown to synergistically enhance the ADCC activity of therapeutic antibodies and anti-tumour activities of checkpoint inhibitors (anti-PD-1, anti-PD-L1 and anti-CTLA4 antibodies) in preclinical studies [2].
