Dual targeting of CD137 co-stimulatory and PD-1 co-inhibitory molecules for ovarian cancer immunotherapy

We recently demonstrated that simultaneous targeting of CD137 co-stimulatory and programmed cell death 1 (PD-1) co-inhibitory molecules synergistically induced an anticancer immune response in the ID8 syngeneic orthotopic mouse ovarian carcinoma model. We further showed that the therapeutic efficacy was enhanced by treatment with cisplatin. These findings provide a rationale for evaluating dual targeting of CD137/PD-1 co-signaling molecules in ovarian cancer patients.
