Abstract: Provided herein are compositions and methods for providing long-term and sustained CAR T cell efficacy. For example, expression cassettes that encode both a GPC2-targeting chimeric antigen receptor and a bispecific innate immune cell engager binding both GD2 on tumor cells and CD16A on natural killers (NK) and macrophages are provided. In addition, T cells that both expression a GPC2-targeting chimeric antigen receptor on their surface and secrete a bispecific innate immune cell engager binding both GD2 on tumor cells and CD16A on natural killers (NK) and macrophages are provided.

Abstract: The present disclosure is directed to antibodies binding to Glypican 2 and methods of using such antibodies to treat cancers that express or overexpress the Glypican 2 antigen.

Abstract: The present disclosure generally relates to, inter alia, antibodies and chimeric antigen receptors (CARs) that bind a Glypican 2 (GPC2) antigen. The disclosure also provides compositions and methods useful for producing such antibodies and CARs, as well as methods for the diagnosis, prevention, and/or treatment of health conditions associated with the GPC2 antigen expression.
