Ipilimumab With or Without High-Dose Recombinant Interferon Alfa-2b in Treating Patients With Stage III-IV Melanoma That Cannot Be Removed by Surgery

Study Overview
=================
Brief Summary
-----------------
This randomized phase II trial studies how well ipilimumab with or without high-dose recombinant interferon alpha-2b works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Monoclonal antibodies, such as ipilimumab, may block tumor growth by targeting certain cells. Recombinant interferon alfa-2b may interfere with the growth of tumor cells. It is not yet known whether ipilimumab is more effective with or without high-dose recombinant interferon alfa-2b in treating melanoma.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. Test the hypothesis that the combination of ipilimumab and high-dose interferon-alpha 2b (HDI [recombinant interferon alfa-2b]) will improve progression free survival (PFS) of patients with advanced metastatic melanoma as compared to ipilimumab alone (across ipilimumab treatment status). SECONDARY OBJECTIVES: I. Test the hypothesis that the combination of ipilimumab and HDI will prove to be safe and tolerable. II. Within the constraints of the sample size, attempt to test the hypotheses that (1) ipilimumab 10 mg/kg will lead to improved PFS in comparison to ipilimumab 3 mg/kg (across HDI treatment status); (2) the combination of ipilimumab and HDI will improve overall survival (OS) of patients with advanced metastatic melanoma as compared to ipilimumab alone (across ipilimumab treatment status) and (3) ipilimumab 10 mg/kg will lead to improved OS in comparison to ipilimumab 3 mg/kg (across HDI treatment status). OUTLINE: Patients are randomized to 1 of 4 treatment arms. ARM A: INDUCTION PHASE: Patients receive higher dose ipilimumab intravenously (IV) over 90 minutes once every 3 weeks for 4 doses and recombinant interferon alfa-2b IV over 20 minutes 5 days a week for 4 weeks and then subcutaneously (SC) 3 times weekly for 8 weeks. MAINTENANCE PHASE: Patients receive higher dose ipilimumab IV over 90 minutes once every 12 weeks for 4 doses beginning in week 24 and recombinant interferon alfa-2b SC 3 times weekly for 48 weeks. ARM B: INDUCTION PHASE: Patients receive higher dose ipilimumab IV over 90 minutes once every 3 weeks for 4 doses. MAINTENANCE PHASE: Patients receive higher dose ipilimumab IV over 90 minutes once every 12 weeks for 4 doses beginning in week 24. ARM C: INDUCTION PHASE: Patients receive lower dose ipilimumab IV over 90 minutes once every 3 weeks for 4 doses and recombinant interferon alfa-2b IV over 20 minutes 5 days a week for 4 weeks and then SC 3 times weekly for 8 weeks. MAINTENANCE PHASE: Patients receive lower dose ipilimumab IV over 90 minutes once every 12 weeks for 4 doses beginning in week 24 and recombinant interferon alfa-2b SC 3 times weekly for 48 weeks. ARM D: INDUCTION PHASE: Patients receive lower dose ipilimumab IV over 90 minutes once every 3 weeks for 4 doses. MAINTENANCE PHASE: Patients receive lower dose ipilimumab IV over 90 minutes once every 12 weeks for 4 doses beginning in week 24. In all arms, treatment continues in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually for up to 5 years.

Eligibility Criteria
-----------------
Inclusion Criteria: Patients must have unresectable stage III or stage IV melanoma, either initial presentation or recurrent, that is of cutaneous origin or unknown primary origin and that is histologically diagnosed No more than one prior systemic therapeutic regimen for unresectable stage III or stage IV melanoma; this includes chemotherapy, biologic therapy, biochemotherapy, or investigational treatment; this does not include any therapies given in the adjuvant setting; however, patients are excluded if they have a history of prior treatment for melanoma (either adjuvant or metastatic disease) with ipilimumab or other cytotoxic T-lymphocyte antigen 4 (CTLA-4) inhibitor, or prior interferon-alpha treatment for metastatic disease (history of adjuvant interferon-alpha is allowed); there should be a 4-week washout period between last treatment administration and initiation of study therapy Patients must have Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 Patients must not have other significant medical, surgical, or psychiatric conditions or require any medication or treatment that in the opinion of the investigator may interfere with compliance, make the administration of ipilimumab or HDI hazardous or obscure the interpretation of adverse events (AEs), such as a condition associated with frequent diarrhea; patients must not have an active infection requiring current treatment with parenteral antibiotics Patients must not have a history of inflammatory bowel disease or diverticulitis (history of diverticulosis is allowed) Patients who have other current malignancies are not eligible; patients with other malignancies are eligible if they have been continuously disease free for > 5 years prior to the time of randomization; one exception are patients treated with a curative intent and are continuously disease free for > 3 years;
