Patient case: 70-year-old male with melanoma; genetic feature: NF1 truncation

Clinical trial: Gene Therapy in Treating Patients With Stage III or Stage IV Melanoma

Summary: RATIONALE: Injecting allovectin-7 into a person's melanoma cells may make the body build an immune response that will kill tumor cells.
  PURPOSE: Phase II trial to study the effectiveness of gene therapy in treating patients who have stage III or stage IV melanoma that has not responded to previous treatment.

Detailed description: OBJECTIVES: I. Demonstrate an objective clinical response (partial or complete) with a median duration of at least 4 months in 15% of patients with stage III or IV melanoma treated with Allovectin-7. Allovectin-7 is a direct gene transfer immunotherapeutic agent.
  II. Determine the benefits, risks, and side effects of Allovectin-7 in this patient population.
  PROTOCOL OUTLINE: This is a multicenter study. Patients receive an intratumoral injection of Allovectin-7 once weekly for 6 weeks. At week 9, a complete disease status assessment is performed. Patients with stable or responding disease may receive additional courses of 6 injections.
  PROJECTED ACCRUAL:
  A total of 70 patients will be accrued for this study.
