Abstract
PD-L1 and ICOS are immune control points in cancer and their presence in cancer tends to have a poor prognosis. WO2019122882 patent describes a bispecific antibody that targets PDL-1/ICOS with the potential application of cancer treatment. WO2019122882 patent describes a bispecific antibody with antitumor efficacy in CT26 model through of the depletion of TReg cells and improved ratio of CD8+ T cells: TReg in tumor microenvironment. The anti-PDL-1/ICOS antibody is new; however, only preclinical assays are shown using colon carcinoma model. So far, there are no reports of clinical trials to evaluate the safety, toxicity and efficacy, but it will be of great interest to analyze in the future if this antibody surpasses the action of the combinatorial therapy in cancer.
