<qa>  What is the purpose of this study?This study is an open-label, fixed-dose, multicenter study of MDX-060 in patients with ALCL who have relapsed or refractory disease. There will be 3 phases of this study: Induction, Maintenance, and Follow-up. Patients will be required to attend all protocol-required visits in the 4-week Induction Phase, in which administration of MDX-060 will occur, as well as other testing. Patients who complete the Induction Phase may be eligible for additional MDX-060 treatment ever 2 months for 1 year in the Maintenance Phase. Patients who complete the Maintenance Phase with a response of stable disease or better will be followed every 2 months for 1 year or until disease progression. The purpose of this study is to determine objective response rate at Day 50 in patients with relapsed or refractory classic systemic ALCL or primary cutaneous ALCL treated with MDX-060. Other objectives will be evaluated.
