Official title

Measuring the Impact of Tecfidera on the Gut Microbiota: Does a Change in the Gut Flora Correlate With Gastrointestinal Disturbances Following Therapy Initiation?

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Objectives: Dimethyl fumarate (DMF) therapy may cause a measureable change in bacterial species of the gut. The primary objectives of this study are: 1. Determine whether a measureable change in bacterial species representation follows the institution of DMF. 2. Determine whether a specific pattern of change in the microbiota phylotype with DMF therapy correlates to onset and severity of gastrointestinal disturbances (heartburn, nausea, flatulence, and diarrhea). 3. Determine whether any instability of microbiota phylotype representation persists following the institution of DMF or whether stabilization relates to resolution of gastrointestinal disturbances. 4. Determine whether there is a correlation between a pre-existing functional bowel disorder and development or severity of gastrointestinal disturbances and of peripheral eosinophilia. Design: Double-blinded, prospective, single-center pilot study. Patient Population: Individuals 18 years or older, with a confirmed diagnosis of a relapsing form of multiple sclerosis. Treatment Groups: This study will be an open-label prospective study design with respect to MS immunomodulatory therapy choice. Study group will be defined as subjects with a relapsing form of multiple sclerosis, as defined by the McDonald criteria, choosing to begin DMF therapy.
