What is Varlilumab?

Varlilumab is a human agonistic monoclonal antibody that binds CD27, a co-stimulatory tumor necrosis factor family receptor on T lymphocytes, memory B cells and natural killer cells. By engaging CD27, it aims to enhance T-cell and NK cell activation and cytotoxic responses against CD27-expressing tumor cells. It is studied in glioblastoma and melanoma.
