Molecular Templates to Present on Phase I Dose Escalation Study of MT-6402 at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting

AUSTIN, Texas, May 26, 2023 (GLOBE NEWSWIRE) -- Molecular Templates, Inc. (Nasdaq: MTEM, “Molecular Templates,” or “MTEM”), a clinical-stage biopharmaceutical company focused on the discovery and development of proprietary targeted biologic therapeutics, engineered toxin bodies (“ETBs”), to create novel therapies with potent differentiated mechanisms of action for cancer, announced today the presentation of a poster at the American Society of Clinical Oncology (“ASCO”) Annual Meeting, taking place June 2-6, 2023 in Chicago, IL. One-on-one meetings may be scheduled directly with Molecular Templates.

The poster will highlight interim efficacy and safety data on MT-6402, MTEM’s ETB program designed to activate T-cells through direct cell-kill of immunosuppressive PD-L1+ immune cells. MT-6402 can also deliver and induce the presentation of an MHC class I CMV antigen on tumor cells (antigen seeding mechanism of action) for pre-existing CD8 T-cell recognition and destruction in HLA-A*02/CMV+ patients with high PD-L1 expression on their tumors. MT-6402 continues to demonstrate pharmacodynamic effects and monotherapy activity in heavily pre-treated checkpoint therapy experienced patients. To date, no instances of capillary leak syndrome or other manifestations of innate immunity have been observed with any next-generation ETB. 

Presentation Title: MT-6402, an engineered toxin body (ETB) targeting PD-L1: Interim efficacy and safety data
Poster Number: 2552
Session: Developmental Therapeutics – Immunotherapy
Date/Time: 8 – 11am CST Saturday, June 3, 2023
Location: Board #394, Hall A (McCormick Place)
The poster will be available in the Presentations section of MTEM’s website.
