Tolerability of Rebif® (Interferon-beta 1-A) Therapy in Korean Patients With Multiple Sclerosis

2014-08-27 03:15:42 | BioPortfolio

Summary

This is an observational study to assess the tolerability of Rebif treatment in Korean multiple sclerosis (MS) subjects.

Description

The present observational study is being conducted to assess the safety information from a target of 100 Korean subjects with MS treated with Rebif. Various parameters like subjects' background (age, sex, BMI), MS history, MS status (MS type, Expanded Disability Status Score [EDSS] and others), MS Treatment Concern Questionnaire (MSTCQ), Rebif treatment status, concomitant disease modifying agents (DMA) therapy and Rebif related adverse events will be collected. Subjects will be followed for 12 months. Proportion of subjects with moderate to severe (Grade 3-5) injection site reactions after 3, 6, 12 months of Rebif treatment will be determined. Secondary outcomes like annual relapse rate, change in EDSS, changes in MSTCQ, time to first relapse and incidence of side effects associated with Rebif therapy will also be determined and presented descriptively.

OBJECTIVES

Primary objectives

- To assess the tolerability of Rebif treatment in Korean MS subjects in a non-interventional setting Secondary Objectives

- To evaluate subject's satisfaction, clinical data and disease characteristics of the population of MS subjects undergoing Rebif treatment.

Medical and Biotech [MESH] Definitions

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.

A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (From Ann Neurol 1994;36 Suppl:S73-S79; Adams et al., Principles of Neurology, 6th ed, pp903-914)

An interferon beta-1 subtype that has a methionine at position 1, a cysteine at position 17, and is glycosylated at position 80. It functions as an ANTI-VIRAL AGENT and IMMUNOMODULATOR and is used to manage the symptoms of RELAPSING-REMITTING MULTIPLE SCLEROSIS.

An interferon regulatory factor that is induced by INTERFERONS as well as LMP-1 protein from EPSTEIN-BARR VIRUS. IRF-7 undergoes PHOSPHORYLATION prior to nuclear translocation and it activates GENETIC TRANSCRIPTION of multiple interferon GENES.

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)
