BACKGROUND Alemtuzumab is a humanised monoclonal antibody that depletes lymphocytes, causing long-term immunomodulation. In a 3-year, rater-blinded phase 2 study (the CAMMS223 study) in patients with relapsing-remitting multiple sclerosis (RRMS), alemtuzumab reduced relapse rate and the risk of sustained accumulation of disability compared with subcutaneous(More)
BACKGROUND The anti-CD52 monoclonal antibody alemtuzumab reduces disease activity in previously untreated patients with relapsing-remitting multiple sclerosis. We aimed to assess efficacy and safety of alemtuzumab compared with interferon beta 1a in patients who have relapsed despite first-line treatment. METHODS In our 2 year, rater-masked, randomised(More)

Patients with worsening relapsing-remitting multiple sclerosis (MS), secondary progressive MS, and progressive relapsing MS are potential candidates for treatment with mitoxantrone. Early identification of these patients is essential because there is emerging evidence that early and aggressive treatment might delay or limit long-term disability. Treatment(More)
OBJECTIVE To report the long-term safety and efficacy results from CAMMS223 comparing alemtuzumab with interferon β-1a in early, active relapsing-remitting multiple sclerosis (RRMS). What are the long-term effects of alemtuzumab treatment, received 36 to 48 months previously, on relapse and disability in early, active RRMS? This study provides evidence of(More)
Treatment of early relapsing-remitting multiple sclerosis with the lymphocyte-depleting humanized monoclonal antibody alemtuzumab (Campath [registered trade mark]) significantly reduced the risk of relapse and accumulation of disability compared with interferon β-1a in a phase 2 trial [Coles et al., (Alemtuzumab vs. interferon β-1a in early multiple(More)
Multiple sclerosis (MS) is an immune-mediated neurologic disease in which acute inflammatory events early in the disease course contribute to subsequent neurologic disability. The early relapsing inflammatory phase is followed by a progressive degenerative phase in which the frequency of acute inflammatory attacks diminishes but progressive loss of(More)
Multiple sclerosis (MS) is an autoimmune disorder characterized by CNS inflammation, demyelination and cellular damage with atrophy. Most patients with MS initially present with a relapsing-remitting course, with periodic episodes of neurologic symptomatology that do not follow a predictable pattern. In order to maintain a stable clinical course, it is felt(More)
Mitoxantrone, a synthetic anthracenedione, was developed in the 1980s as a doxorubicin analogue in a program to find a cytotoxic agent with decreased cardiotoxicity compared with doxorubicin. It was approved by the FDA in 1987 for the treatment of adult acute myeloid leukemia and in 1996 for symptomatic hormone-refractory prostate cancer. In 2000,(More)
