TCR² Therapeutics Presents Preclinical Data on Functional Activity of Gavo-cel at the Society for Immunotherapy of Cancer

November 07, 2022 at 08:01 AM EST

CAMBRIDGE, Mass., Nov. 07, 2022 (GLOBE NEWSWIRE) -- TCR² Therapeutics Inc. (Nasdaq: TCRR), a clinical-stage cell therapy company with a pipeline of novel T cell therapies for patients suffering from solid tumors, today announced the poster presentation of new preclinical data at the Society for Immunotherapy of Cancer (SITC) Conference 37th Annual Meeting, taking place November 8-12, 2022. The poster entitled “The Functional Activity of gavo-cel TRuC-T Cells is Not Impaired by Soluble Mesothelin” highlights preclinical data evaluating the impact of soluble mesothelin at high, supraphysiological levels on the functional activity of the Company’s proprietary autologous and allogeneic mesothelin-directed T Cell Receptor Fusion Construct (TRuC^®) T cells.

Mesothelin (MSLN), a protein which plays an active role in both malignant transformation and tumor aggressiveness, undergoes shedding in the tumor microenvironment, generating soluble mesothelin (sMSLN). These sMSLN levels are associated with tumor burden in malignant pleural/peritoneal mesothelioma (MPM). High, circulating levels of sMSLN have been implicated as a potential obstacle to maximizing the activity of anti-mesothelin therapies. To address the potential impact of sMSLN on the function of gavo-cel, acute and chronic in vitro challenge studies were performed in the presence of supraphysiological sMSLN levels. Levels of sMSLN 50-fold higher than were measured in MPM patients had no observed impact on the functional activity of gavo-cel T cells with respect to tumor cell killing and cytokine production. These results suggest that the levels of sMSLN present in the circulation of MPM patients likely do not pose a concern for the clinical activity of gavo-cel.
