• • Significant leucopenia (white blood cell count less than 0.5 times the lower limit of normal) within 7 days of Study Day 1
• • Elevated liver function tests (Alanine transaminase \[ALT\], Aspartate transaminase \[AST\], alkaline phosphatase or total bilirubin greater than 2 times the upper limit of normal) within 7 days of Study Day 1
• • Prior cytokine or anti-cytokine therapy or glatiramer acetate within the 3 months before Study Day 1
• • Immunomodulatory or immunosuppressive therapy within the 12 months before Study Day 1, including but not limited to cyclophosphamide, cyclosporin, methotrexate, azathioprine, linomide and mitoxantrone
• • Previous use of cladribine or total lymphoid irradiation
• • Allergy to human serum albumin, mannitol or gadolinium diethylenetriaminepentacetic acid (DTPA)
• • Intravenous immunoglobulin or any other investigational drug or procedure in the 6 months before Study Day 1
• • Systemic disease that can interfere with subject safety, compliance or evaluation of the condition under study, such as insulin-dependent diabetes, Lyme disease, clinically significant cardiac disease or infection with human immunodeficiency virus (HIV) or Human T-cell lymphotrophic virus, Type-1 (HTLV-1)
