Summary

Recombinant human interleukin‑2 (aldesleukin) is an immunostimulatory cytokine approved for metastatic renal cell carcinoma and melanoma; it enhances T‑cell and NK‑cell mediated anti‑tumor responses.

Mechanism of Action

Activates the IL-2 receptor (CD25/CD122/CD132) leading to proliferation of activated T cells and NK cells

Routes of Administration

IntravenousSubcutaneous
