Patient case: 60-year-old male with melanoma; genetic feature: NTRK1 rearrangement

Clinical trial: flt3L With or Without Vaccine Therapy in Treating Patients With Metastatic Melanoma or Renal Cell Cancer

Summary: RATIONALE: The drug flt3L may stimulate a person's immune system and help to kill tumor cells. Vaccines made from melanoma cells may make the body build an immune response to and kill their tumor cells.
  PURPOSE: Phase II trial to study the effectiveness of flt3L with or without vaccine therapy in treating patients with metastatic melanoma or renal cell cancer.

Detailed description: OBJECTIVES: I. Evaluate the immunologic and biologic activity of flt3 ligand (Flt3L) alone in patients with metastatic renal cell cancer or HLA-A2.1 negative melanoma.
  II. Evaluate the immunologic and biologic activity of Flt3L alone or in combination with melanoma peptide immunization (MART-1, gp100:209-217, gp100:280-288, and tyrosinase) in patients with metastatic, HLA-A2.1 positive melanoma.
  PROTOCOL OUTLINE: Patients are assigned to 1 of 3 treatment groups:
  Group 1 (renal cell cancer): Patients receive Flt3 ligand (Flt3L) subcutaneously (SQ) alone on days 1-14.
  Group 2 (HLA-A2.1 negative melanoma): Patients receive Flt3L SQ alone on days 1-14.
  Group 3 (HLA-A2.1 positive melanoma): Patients may receive either Flt3L SQ alone on days 1-14 or in combination with melanoma peptide immunization. Patients may receive melanoma peptide immunization comprised of MART-1 immunodominant peptide, gp100:209-217, gp100:280-288, and tyrosinase peptide emulsified in Montanide ISA-51 SQ on day 12 of Flt3L administration.
  Treatment repeats every 4 weeks for 2 courses. Patients with no response or minor response may receive 2 additional courses. Patients with disease progression after 1 course are removed from study.
  PROJECTED ACCRUAL:
  Approximately 54-96 patients (18-32 per treatment group) will be accrued for this study within 16 months.
