- Best Objective Response Rate (BORR) [ Time Frame: Up to 44 months ]Intention to treat response rate is estimated by the proportion of patients with a best response of CR, PR, or SD by Response Evaluation Criteria in Solid Tumors [RECIST] version 1.0
- Progression-free Survival (PFS) [ Time Frame: Up to 44 months ]Time from initial treatment date of to date of documented progression of disease progression (TTP)
- 1-year Overall Survival (OS) [ Time Frame: Time from initial treatment date, up to 1 year ]1-year survival is the estimated probability of surviving one year expressed as a percent (probability of survival is not probability of dying).
- Median Overall Survival (Point Estimate) [ Time Frame: Up to 44 months ]Median overall survival is the (point) estimate of the time corresponding to 50% estimated probability of survival.

Experimental: Anti-CTLA4 monoclonal antibody and HDI
Specific Aim #1: Test the hypothesis that the combination of IFNa-2b and anti-CTLA-4 monoclonal antibody will improve the response rate in patients with recurrent inoperable AJCC stage III and stage IV melanoma. Our therapeutic target is achieving, with acceptable toxicity, a 20% or better rate of objective response, CR or PR by RECIST criteria, as compared to the 5% to 10% expected in patients eligible for study. Study size is planned in terms of our primary efficacy endpoint, objective response.
Drug: Anti-CTLA4 monoclonal antibody and HDI
One course of therapy consists of three cycles (1 cycle=28days). Anti-CTLA4 monoclonal antibody (15 mg/kg i.v.) will be given during the first cycle only. HDI will be given all three cycles - cycle 1: 20 MU/m2 i.v. on days 0, 1, 2, 3, 4 a week (MTWRF) for 4 weeks; cycle 2: 10 MU/m2 s.c. 3 days a week (MWF) for 4 weeks; and cycle 3: 10 MU/m2 s.c. 3 days a week (MWF) for 4 weeks.
Response assessment will be carried out at day 56 and day 84. Every patient will receive 3 cycles regardless of response status after the first 2 cycles. However, a patient may be taken off therapy in the event of clinical progression at the discretion of the treating physician.
Patients without evidence for disease progression after 3 cycles may be offered additional cycles two weeks after completion of the third cycle. Therapy will continue for a maximum of 12 months.
Other Name: Anti-CTLA4 monoclonal antibody (CP-675,206)
