New therapies that promote antitumour immunity have been recently developed. Most of these immunomodulatory approaches have focused on enhancing T-cell responses, either by targeting inhibitory pathways with immune checkpoint inhibitors, or by targeting activating pathways, as with chimeric antigen receptor T cells or bispecific antibodies. Although these therapies have led to unprecedented successes, only a minority of patients with cancer benefit from these treatments, highlighting the need to identify new cells and molecules that could be exploited in the next generation of immunotherapy. Given the crucial role of innate immune responses in immunity, harnessing these responses opens up new possibilities for long-lasting, multilayered tumour control.

Current clinical landscape of drugs targeting innate immunity. A selection of active clinical programs targeting innate immunity in cancer therapy is presented. The table is organized according to four modes of action: A) Capitalizing on antimicrobial immunity for tumor control; B) Induction and amplification of the innate immune response; C) Promotion of the effector responses of innate immunity; D) Relieving immune suppression at the tumor bed. Abbreviations: A, approved; 2019, IND planned in 2019; *see box 3; $programs stopped in phase III but still active in phase I and II trials.
