Interleukin-21 in Treating Patients With Metastatic or Recurrent Malignant Melanoma
A Phase II Study of Interleukin-21 (IL-21) in Patients With Metastatic or Recurrent Malignant Melanoma

RATIONALE: Interleukin-21 may stimulate white blood cells, including natural killer cells, to kill melanoma cells.

PURPOSE: This phase II trial is studying the side effects and how well interleukin-21 works in treating patients with metastatic or recurrent malignant melanoma.



  • To assess the efficacy, in terms of objective response rate, nonprogression rate, time to progression, and response duration, in patients with metastatic or recurrent malignant melanoma treated with recombinant human interleukin-21 (rIL-21).
  • To assess the toxicity and safety of rIL-21 in patients with previously untreated metastatic or recurrent malignant melanoma.
  • To characterize the pharmacokinetics of rIL-21.
  • To characterize the effects of rIL-21 on lymphocyte cell count and soluble CD25 (sCD25) in serum as potential biomarkers for drug activity.
  • To evaluate the immunogenicity of rIL-21, specifically preexisting immunogenicity to the drug and antibody induction during treatment.
  • To assess melanoma antigenic markers for response and nonprogression on archival tissue from patients enrolled on the study.


  • To investigate whether rIL-21 induced sCD25 release is independent of the level of circulating sCD25.
  • To investigate the effect of rIL-21 on antibody induction during treatment and preexisting immunogenicity.
  • To assess lymphocyte cell-count changes over time in relation to rIL-21 therapy.

OUTLINE: This is a multicenter study.

Patients receive recombinant human interleukin-21 (rIL-21) IV on days 1-5 of weeks 1, 3 and 5. Treatment repeats every 8 weeks in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) or partial response (PR) receive 2 courses beyond CR or PR. Patients with stable disease receive a maximum of 3 courses of rIL-21.

Previously archived tumor tissue and blood samples are collected from patients for correlative studies. Samples are analyzed for soluble CD25, rIL-21 antibodies, circulating lymphocyte counts, preexisting immonogenicity to rIL-21 for antibody induction, and expression of common melanoma tumor antigen markers via IHC.

After completion of study treatment, patients are followed at 4 weeks.
