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

Phase 2

Completed

• Conditions: Stage IV Melanoma; Recurrent Melanoma; Recurrent Renal Cell Cancer; Stage IV Renal Cell Cancer

• Registration Number: NCT00019396
• Lead Sponsor: National Cancer Institute (NCI)

Brief 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.
