Monoclonal Antibodies

Solid Organ Malignancies

Anti-PD-1 Antibodies

    IV infusion
    IV infusion
    • Mechanism of Action
    • Monoclonal antibodies directed against programmed cell death protein 1 (PD-1), a surface co-inhibitory receptor on circulating activated T cells, B cells and NK cells.
    • PD-1 binds to two ligands (PD-L1 and PD-L2) and inhibit T cell receptor signalling, downregulating immune responses and promoting tolerance.
    • Many tumours express or overexpress PD-L1.
    • Binding of anti-PD1 monoclonal antibodies to PD-1 leaves the ligand unable to bind, and therefore stimulates an ongoing immune response.

Clinical Use

    • Indications
    • Certain solid organ and haematologic malignancies with high levels of microsatellite instability (MSI). Malignancies of particular interest are melanoma, non-small cell lung cancer, renal cancer and bladder cancer, though this is a rapidly growing field.
