RE:RE:RE:RE:RE:RE:ONCY pelareorep + CD3 bispecific antibody true-killer comboJanuary 31, 2024 - Pfizer drops PF-07260437, a phase 1 therapy designed to treat advanced breast cancer, ovarian cancer or endometrial cancer.
The B7-H4 x CD3 bispecific monoclonal antibody was intended to potentially help B7-H4 in favorably manipulating breast tumor immune microenvironment (TME), but was unable to achieve, and in which ONCY's pelareorep x CD3 has been able to unequivocally demonstrate by inducing a local interferon response and strong T-cell influx, thereby sensitizing and remodeling the tumor microenvironment for the addition of a subsequent immune checkpoint inhibitor.
