About Uliledlimab

Uliledlimab (also known as TJD5) is a differentiated, humanized antibody against CD73, an ecto-enzyme expressed on stromal cells and tumors that converts extracellular adenosine monophosphate (AMP) to adenosine. Adenosine, in turn, binds to adenosine receptors on relevant immune cells and inhibits anti-tumor immune responses in the tumor microenvironment. Uliledlimab is expected to offer clinical benefits by suppressing tumor growth in concert with checkpoint therapies such as PD-(L)1 antibodies. Uliledlimab is effective in anti-tumor activities through a unique intra-dimer binding, leading to differentiated and favorable functional properties, as evident in preclinical studies.
