Denileukin diftitox is administered by a doctor or nurse in a medical office or infusion center. It is usually given once a day for 5 days in a row.

Denileukin Diftitox Genetic Information

Cutaneous T-cell lymphoma (CTCL) is a cancer of a certain type of white blood cells called T-cells. CTCL occurs when T cells grow and divide rapidly. The interleukin-2 (IL-2) receptor is a protein found on the surface of T-cells that controls the growth and division of T-cells. Some patients have a version of the IL-2 receptor that contains another protein called CD25.

CD25 testing is done to determine whether denileukin diftitox is likely to be effective in treating CTCL. If testing is not done, treatment with denileukin diftitox may not be effective.

Denileukin diftitox is approved for the treatment of patients with CTCL that has not responded to other treatment, or that has recurred. The patient's cancer cells should contain the CD25 protein in order to be treated with denileukin diftitox. Denileukin diftitox works by binding to the IL-2 receptor located on cancer cells. The drug is then taken into the cancer cells where it kills the cancer cells.
