Multifunctional antibody formats for combination with in situ tumor ablation. Administration of 1. bispecific agonistic antibodies (e.g. anti-MSLN-CD40) or 4. antibody-adjuvant fusions (e.g. chTNT3-CpG) will lead to local APC activation. Interventions such as 2. bispecific ICB (e.g. PD-L1xErbB2 antibody) may further stimulate myeloid as well as T cell immunity specifically within the TME; 3. antibody-enzyme fusions allow tumor specific sialoglycan degradation (e.g. anti-HER2 mAb-sialidase); 5. antibody-cytokine fusions (e.g. anti-GD2-IL2) will result in targeted cytokine delivery ensuring local immune cell activation, all are aimed at relieving local immunosuppression.
