ABSTRACT
Introduction: GITR is a receptor that increases the activation of T lymphocytes against tumor cells. There is a great need to discover and develop new therapies focused on activating GITR to increase the immune response in various types of cancer. The authors of WO2018091739 patent propose a method to eradicate cancer by using bispecific anti-GITR/anti-CTLA-4 antibodies.
Areas covered: WO2018091739 patent describes anti-GITR/anti-CTLA-4 antibodies, pharmaceutical composition that contains it, and their application for cancer treatment, particularly colon carcinoma. Anti-GITR/anti-CTLA-4 antibodies are used at a dosage of 0.0003–3 mg antibody/kg patient weight and is suspended in an isotonic solution consisting of sodium phosphate, sucrose, NaCl, and polysorbate 80.
Expert opinion: WO2018091739 only demonstrates that bispecific antibodies activate T cells, an antibody-dependent cellular cytotoxicity of CHO cells, and tumor inhibition in murine models of colon carcinoma. There are no clinical trials that show that treatment with bispecific antibodies can induce an antitumor response in cancer patients.
