Implications for Patient Care

  • Denileukin diftitox is a recombinant DNA-derived cytotoxic protein. It is labeled for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma (CTCL) whose malignant cells express the CD25 component of the interleukin-2 (IL-2) receptor.2-4
  • Denileukin diftitox is used off-label for the treatment of chronic lymphocytic leukemia refractory to fludarabine and in non-Hodgkin lymphoma.2-4

Safety

  • Chemotherapy agents, such as denileukin diftitox, pose additional safety risks both for patients and for healthcare workers handling these agents.2,3
  • Use additional caution when processing orders for chemotherapy drugs, especially when switching between chemotherapy agents or when processing orders for chemotherapy agents with which staff may be unfamiliar (eg, those not normally prescribed at a specific institution).2,3

Alternative Agents & Management

  • The choice of an alternative agent must be patient-specific and based on renal function, liver function, and the neoplasm type and location. No single agent can be substituted for denileukin diftitox.2-4
  • Consult a Hematology/Oncology specialist for patient- and neoplasm-specific recommendations.
  • Refer to the ASHP Guidelines on Managing Drug Product Shortages for more guidance on developing a multidisciplinary plan when the supply must be allocated.
