New Data on Molecular Templates' Engineered Toxin Bodies to be Presented at the American Association of Cancer Research (AACR) Virtual Annual Meeting II
AUSTIN, Texas,, May 15, 2020 (GLOBE NEWSWIRE) -- Molecular Templates, Inc. (Nasdaq: MTEM, “Molecular Templates,” or “MTEM”), a clinical-stage biopharmaceutical company focused on the discovery and development of the Company’s proprietary targeted biologic therapeutics, engineered toxin bodies (ETBs), today announced that new preclinical data on its pipeline programs and technology platform will be presented at the AACR Virtual Annual Meeting II to take place June 22-24, 2020. All four posters are expected to be available on the AACR website on June 22, 2020.
MT-6402 is a highly differentiated approach to immuno-oncology. MT-6402 target PD-L1 and has been shown in preclinical studies to induce three unique biological effects:
Non-human primate (NHP) data presented at the AACR meeting show that MT-6402 mediated PD-L1+ immune cell clearance can elicit highly potent monotherapy immune activation in a way that has not been seen previously in NHP models with checkpoint inhibitors.
Tumor resident regulatory T cells (Treg) are important mediators of an immunosuppressive tumor microenvironment (TME) promoting tumor immune evasion. The presence of Tregs, and a higher ratio of Tregs to effector T cells in the TME, are associated with poor prognosis. There is concern that antibodies to CTLA-4 are not sufficiently effective at clearing Tregs from the TME. ETBs are being developed to specifically target CTLA-4+ Tregs and clear them from the TME. The clearance of Tregs in the TME is expected to re-expose the tumor to the immune system to allow for tumor control. Because CTLA-4-targeted ETBs preferentially affect Tregs versus CTLA-4+ CD8 T-cells, ETBs may also have a safer profile than CTLA-4 antibodies.
SLAMF7 (CS1) is a clinically validated target of monoclonal antibody therapy for the treatment of multiple myeloma. The approved antibody-based therapeutic, elotuzumab, works indirectly by recruiting effector cells to the tumor but does not show single agent clinical activity. ETBs have the potential to deplete malignant cells by means of potent and direct cell kill through enzymatic ribosomal destruction.
CD45, the leucocyte common antigen, is a haemopoietic cell-specific tyrosine phosphatase. Targeted and potent ETBs with intrinsically short half-lives are being developed to specifically destroy CD45 expressing cells including malignant cells of B, T and myeloid lineage. A single agent, targeted conditioning method for bone marrow transplant (BMT), employing ETBs, has the potential to increase patient safety and eliminate genotoxic effects that are associated with existing conditioning regimens.
