Molecular Templates, Inc. is a clinical-stage biopharmaceutical company focused on the discovery and development of targeted biologic therapeutics. The Company’s proprietary drug platform technology, known as engineered toxin bodies (ETBs), leverages the resident biology of a genetically engineered form of Shiga-like Toxin A subunit to create novel therapies with potent and differentiated mechanisms of action for cancer. Its product pipeline includes MT-6402, MT-8421 and MT-0169. MT-6402 is an ETB consisting of a single chain variable fragments (scFv), with affinity for PD-L1, fused to the enzymatically active de-immunized SLTA and a HLA-A*02 class I antigen derived from the human cytomegalovirus (HCMV) pp65 protein. MT-8421, its ETB targeting CTLA-4, along with MT-6402.
