Treatment of metastatic melanoma with chemotherapeutic regimens has led to disappointing response rates, duration of response and no appreciable impact on survival. Intralesional injection of a low dose of an HLA-B7/beta2 microglobulin plasmid formulated with cationic lipids (Allovectin-7 is a registered trademark of Vical, Incorporated, San Diego, California, USA) has been shown previously to be safe and well tolerated. A phase 2, open-label study was performed at 16 centers in the United States. Seventy-seven patients were treated with 10 mug intralesional Allovectin-7 weekly for 6 weeks and clinical response to treatment were evaluated by World Health Organization criteria. Minimal adverse events were associated with the Allovectin-7 injections. Seven patients (9.1%) had complete or partial response with 4.8 months median duration of response. Allovectin-7 was shown to be safe and exhibit biological activity at this dose. Its safety profile may enable Allovectin-7 to be used at higher doses, which may provide greater clinical activity.
