Multifunctional immunotherapeutic monoclonal antibody complexes and conjugates

Abstract

Immunotherapeutic Monoclonal Antibody Complexes or Conjugates (IMAC) comprising readily accessible antibodies designed and approved for clinical use are provided using a one-step method that combines killing of existing cancer cells in parallel with induction of long-lasting anti-cancer vaccination. Methods for their use, alone or in combination with cancer killer cells including intentionally mismatched donor T cells, NK cells concomitantly with additional anti-cancer or immune activating agents, or activation of patient's own immune system for personalized treatment of cancer and elimination of undesirable non-malignant cells are also provided. In addition, treatment method based on IMAC can be applied for in vivo vaccination against cancer using an existing malignant lesion as internal anti-cancer vaccine by engagement of patients antigen presenting cells for induction of long-lasting anti-cancer vaccination in situ against residual or recurrent disease.
