Patient case: 74-year-old female with melanoma; genetic feature: no tumor infiltrating lymphocytes

Clinical trial: MDX-010 Antibody, MDX-1379 Melanoma Vaccine, or MDX-010/MDX-1379 Combination Treatment for Patients With Unresectable or Metastatic Melanoma

Summary: The purpose of this study is to determine the safety and efficacy of MDX-010 (ipilimumab, BMS-734016) (anti-CTLA4) in combination with MDX-1379 (gp100, BMS-734019) in patients with previously treated, unresectable Stage III or IV melanoma. Survival time will be evaluated, as well as patient responses and time to disease progression. Eligible patients are those who in response to a single regimen containing interleukin-2 (IL-2), dacarbazine, and/or temozolomide, have 1) relapsed following an objective response (partial response/complete response [PR/CR]); 2) failed to demonstrate an objective response (PR/CR); or 3) could not tolerate such a regimen due to unacceptable toxicity. Patients will be randomized into one of three groups, and will receive one of the following treatments: MDX-010 alone, MDX-1379 alone, or MDX-010 in combination with MDX-1379.

Detailed description: Melanoma accounts for approximately 5% of all skin cancers in the United States, but it accounts for about 75% of all skin cancer deaths. In 2004, the expected prevalence of melanoma is 627,252, with about 119,178 of these cases being Stage III or IV (metastatic melanoma). First line treatments for metastatic melanoma, usually IL-2, dacarbazine and/or temozolomide, are associated with significant toxicities. MDX-010 (anti-CTLA4) antibodies are designed to keep the immune system running by blocking CTLA-4 from down-regulating T cell activation. MDX-1379 is made up of two peptides that are pieces of a bigger melanoma protein (gp100). These peptides bind to HLA-A2 which is then recognized by T cells.
