Novel agents in development for the treatment of melanoma

Abstract

In 2005, melanoma is estimated to affect 55,000 Americans. Of these, 7700 are estimated to die from the disease. Immunological approaches have yielded the only newly FDA-approved agents for melanoma in 30 years, which includes high-dose bolus IL-2, based on durable responses in some patients with metastatic melanoma. A survival advantage was shown in two of three randomised clinical trials with high-dose IFN-α_2b in the high-risk adjuvant setting. However, both agents are associated with high cost and toxicity rates. A number of novel therapeutic agents are undergoing active clinical investigation. The more promising of these will be discussed in this review, including bcl-2 antisense therapy, v-raf murine sarcoma viral oncogene homologue B1 inhibition, heat-shock proteins, anti-α_vβ₃ integrin monoclonal antibody, thalidomide and newer immunomodulatory drugs, and anti-cytotoxic T lymphocyte-associated protein-4 monoclonal antibody.
