Official titleEffectiveness of Tecfidera® in multiple sclerosis: a French cohort within the nationwide claims and hospital database
Study title acronymEVIDEMS
Study typeOther: Study using the SNIIRAM claims and hospitalisation database
Brief description of the studyMultiple sclerosis (MS) is an incapacitating, progressive, chronic neurological disorder that involves a selective, chronic inflammation and demyelination of the central nervous system. The severity of the disease varies from mildly forms to severe disabilities within a few years. Relapsing-remitting MS forms (RRMS) are the most common, and are characterized by the presence of relapses without disability progression between relapses.
The aim of the disease modifying therapy is to reduce the frequency of relapses and to slow the disability progression. The first-line long-term treatments for RRMS were interferon beta-1a and 1b and glatiramer acetate, while Natalizumab and fingolimod have a Marketing Authorisation restricted to highly active RRMS. Two other oral drugs were approved recently for the treatment of adult patients with MS: teriflunomide marketed since November 2014 and Dimethyl fumarate prescribed within a hospital compassionate use program since March 2014, and officially reimbursed 25 June 2015 for prescription to outpatients.
In the context of the renewal of the registration of Tecfidera® in 2020, this project was designed to assess the drug usage pattern in MS after Tecfidera® launch in France, and to compare the benefit of Tecfidera® to other drugs in current practice, and especially to the two other oral drugs, Aubagio® and Gilenya®, using the SNIIRAM nationwide claims and hospital database.
