Alemtuzumab (previously known as Campath(®)) is a humanized monoclonal antibody directed against the CD52 antigen on mature lymphocytes that results in lymphopenia and subsequent modification of the immune repertoire. Here we explore evidence for its efficacy and safety in relapsing-remitting multiple sclerosis. One Phase II and two Phase III trials of alemtuzumab versus active comparator (inte...

Chemokines play an important role in pathogenesis of multiple sclerosis (MS), mediating migration of leukocytes into the central nervous system. CCL2 (MCP-1) chemokine is expressed in astrocytes in MS lesions. The aim of the study was to evaluate the effect of a two-year treatment with IFN-beta 1a on serum CCL2 level in MS patients. CCL2 concentration in sera of 18 relapsing-remitting MS (RR-MS...

BACKGROUND Interferon inhibitory activity (IIA) is a logical candidate for explaining neutralizing antibody-negative partial responsiveness to interferon beta in multiple sclerosis (MS), but its role has not been evaluated. OBJECTIVE To investigate the role of IIA and soluble interferon-alpha/beta receptor (sIFNR) in determining response of patients with MS to interferon beta therapy. DESIG...

OBJECTIVE Recently, a strong correlation between the increase in hypointense lesion load on T1 weighted spin echo images, and the increase in disability was reported. Although the effect of interferon-beta has been demonstrated both in reducing exacerbation rate, frequency of enhancing lesions, and accumulation of disease burden on T2 weighted images, the impact on the accumulation of hypointen...

The treatment options for multiple sclerosis are rapidly changing. With the increasing number of products available to treat this disease, treatment decisions are becoming more complex. Over the years, diagnosis and assessment of treatment efficacy in multiple sclerosis have evolved, but the primary endpoints used to evaluate patients have remained relatively consistent. Relapse rates, magnetic...

BACKGROUND The EVIDENCE (Evidence of Interferon Dose-Response: European North American Comparative Efficacy) Study demonstrated that patients with multiple sclerosis (MS) who initiate interferon beta-1a therapy with 44 microg 3 times weekly (TIW) were less likely to have a relapse or activity on magnetic resonance imaging (MRI) compared with those who initiate therapy at a dosage of 30 microg 1...

5. Monoclonal Anti body Multi ple sclerosis (MS) is a complex immunopathologic disorder of the central nervous system (CNS). For the past several years, there have been six agents approved by regulatory agencies to treat relapsing forms of multi ple sclerosis (MS): interferon beta-1b, intramuscular interferon beta-1a, subcutaneous interferon beta-1a, glati ramer acetate, natalizumab, and mitoxa...
