OVV-01

This is a prospective, multi-center, open-label, single-arm, investigator-initiated clinical trial to evaluate the safety and efficacy of oncolytic virus injection (OVV-01) in combination with trained immunity NK (tiNK) cell injection (IBR900) for patients with advanced malignant tumors.

Phase Ia: To investigate the safety, tolerability and efficacy of OVV-01 injection in the treatment of patients with advanced solid tumors (OVV-01 single dose gradient exploration).
Phase Ib: To evaluate the safety, tolerability and efficacy of OVV-01 injection combined with immune checkpoint inhibitors pembrolizumab (anti-PD-1 monoclonal antibody) or atezolizumab (anti-PD-L1 monoclonal antibody) in the treatment of patients with advanced solid tumors (OVV-01 combined with PD-1/PD-L1 monoclonal antibody dose gradient exploration);
Phase Ic: A cohort expansion of Phase Ib to further analyze the efficacy and safety of OVV-01 injection combined with immune checkpoint inhibitor injection in the treatment of advanced solid tumors.
