Based on this, AMG 160 (a bispecific T cell engager that binds to the prostate-specific membrane antigen on tumor cells and CD3 on T cells) has been studied in combination with AMG 404 (a PD-1 monoclonal antibody; ClinicalTrials.gov Identifier: NCT04631601) in one trial and in combination with pembrolizumab (ClinicalTrials.gov Identifier: NCT03792841). Here, FOLH1 is linked to neoplasm.
