Ipilimumab (MDX-010) for unresectable stage III or IV metastatic melanoma - first or second line treatment Target group Metastatic melanoma unresectable stage III or IV: First line in combination with dacarbazine Second line monotherapy Technology description Ipilimumab (MDX-010) is an intravenous (IV) fully-human anti-cytotoxic T-lymphocyte antigen-4 (anti-ctla-4) monoclonal antibody. CTLA-4 is an inducible receptor expressed by T-lymphocytes which, when activated, inhibits T-lymphocyte proliferation and function. Ipilimumab blocks CTLA-4, preventing binding of B7 molecules which enables continued CD28-mediated enhancement of T-lymphocyte receptor signalling. Ipilimumab is currently in phase II and III clinical trials for metastatic melanoma, and phase II clinical trials for lung cancer, prostate cancer, bladder cancer, breast cancer, and pancreatic cancer. Innovation and/or advantages Ipilimumab is a biologic agent with a novel mechanism of action and available survival data from phase II studies are promising.

Cutaneous malignant melanoma: ESMO Clinical Recommendations for diagnosis, treatment and follow-up. 2007 6. Clinical need and burden of disease The incidence of malignant melanoma is increasing in England and Wales, with rates doubling approximately every 10-20 years 7. There were 7,363 new cases of malignant melanoma registered in England in 2004, and 1,622 deaths in England and Wales in 2005 8. Although malignant melanoma prognosis and survival has improved over the 2
years, advanced disease still has limited treatment options and generally low survival rates. Younger patients tend to have higher survival rates than older patients; women have a higher survival and lower age-specific mortality rate than men, whilst higher survival rates have been noted in the most affluent, compared to the least affluent societal groups 9. Five-year survival for stage III disease is around 40-50%, and for stage IV disease around 20-30% 10 (median survival is between 6-9 months) 11. Existing comparators and treatments Single-agent chemotherapy with dacarbazine (DTIC), an alkylating agent administered intravenously. A 2007 Cochrane review 12 found that cytotoxic alternatives to DTIC, including temozolomide, cisplatin, carboplatin, vinca alkaloids, taxanes and nitrosoureas had not been shown to improve on standard chemotherapy with DTIC. Combination chemotherapies had also failed to demonstrate any significant benefit, except for a small increase in response rates 13. Chemoimmunotherapy (e.g. DTIC combined with interleukin-2 or interferon) was not found to prolong survival compared to chemotherapy alone, and a short-term increase in clinical response was associated with a higher rate of serious adverse events.
