However, the application of BiTEs in solid tumors has proven challenging, primarily due to the lack of targetable tumor antigens and the immunologically \u201ccold\u201d nature of the tumor microenvironment, which limits immune system activation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We developed a novel oncolytic virus (OV) platform by engineering a chimeric vaccinia virus to express either a truncated non-signaling CD19 antigen (CD19t) or truncated B cell maturation antigen (BCMAt) on the surface of infected tumor cells. Here, we advance a combinatorial platform using an OV to redirect CD19-targeted or BCMA-targeted T cell engagers (TCEs) to drive antitumor responses against multiple solid tumors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>We found that OV-infected tumor cells in combination with TCEs significantly improved tumor cell killing against solid tumor models, with efficacy comparable to that of chimeric antigen receptor T cells. This combination approach enhanced antitumor responses using in vivo human tumor xenograft models and promoted more effective elimination of solid tumor cells than either therapy alone. Our studies highlight OVs combined with clinically approved TCEs as a readily translatable, tumor-agnostic, off-the-shelf strategy to effectively target solid tumors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our findings demonstrate that the combination of OV and TCEs offers a promising strategy to drive antitumor immune responses against solid tumors.
