• Human monoclonal antibodies

    Oncomatryx ADCs comprise a cytotoxic molecule conjugated to a human antibody designed to ensure that the ADC reaches the target cells with high sensitivity and specificity.

    Human anti-MTX5 full IgG1 monoclonal antibodies

    High specificity – High affinityFast internalization

    MTX5

    • OMTX anti-MTX5 humanized mAb IgG1 binds specifically, in a concentration-dependent manner, to both human (a) and murine (b) MTX5, at subnanomolar EC50 values (0.33 and 0.25 nM) in vitro, in MTX5-transfected HT1080 cells and in primary Cancer Associated Fibroblasts from patients (c), as well as in vivo in tumor stroma of pancreas cancer patient-derived xenograft mice after i.p administration (f)
    • OMTX anti-MTX5 humanized mAb affinity and specificity is not affected by conjugation to OMTX payloads (d)
    • OMTX anti-MTX5 humanized mAb is rapidly internalized within cells. 85% of cells showed exclusive intracellular labeling after 60min (e).
