Home PipelineTebotelimab (PD-1 × LAG-3)


Tebotelimab (previously known as MGD013) is an investigational, bispecific DART® molecule designed to independently or coordinately block PD-1 and LAG-3 checkpoint molecules to sustain or restore the function of exhausted T cells for the treatment of cancer. Monoclonal antibodies that target the immune checkpoints Lymphocyte-activation gene 3 (LAG-3) and PD-1 may have enhanced clinical activity when given in combination. Tebotelimab has been engineered to bind PD-1 and LAG-3 concomitantly or independently and disrupt these non-redundant inhibitory pathways to further restore exhausted T-cell function.

Clinical Development

Tebotelimab was being studied in combination with enoblituzumab (an investigational monoclonal antibody that targets B7-H3) in patients with squamous cell carcinoma of the head and neck who are PD-L1 negative. As of July 8, 2022, this study was closed for safety reasons.  Please see press release.
