“Armed” oncolytic herpes simplex virus enables CD19 CAR-T for solid tumor cell treatment as a combination therapy (AACR 2023)
The in vivo efficacy studies demonstrated that IT and IP administration of T7011, rather than MVR-T3011 virus which lacks CD19, specifically promoted CD19 CAR-T anti-solid tumor activities in both immunodeficient and immunocompetent mice. The new-generation of HSV oncolytic virus T7011 expressing the targetable CD19 antigen on tumor surface enables the CD19 CAR-T for solid tumor cell treatment as a combination therapy. The new-generation of HSV oncolytic virus T7011 expressing the targetable CD19 antigen on tumor surface enables the CD19 CAR-T for solid tumor cell treatment as a combination therapy. In addition, T7011 also carries multi-immunomodulators further to enhance antitumor efficacy by reinvigorating the infiltrated CAR-T cells and reversing the immunosuppressive TME. T7011 is expected to be a promising combinational therapy with CD19-specific CAR-T cells enabling effective cell therapy against multiple solid tumors.
