About

The hypothesis is that 95% pure EGCG can protect brain cells in patients with Multiple Sclerosis. To test this hypothesis we are going to compare the changes in n-Acetyl-Aspartate (a chemical that reflects the number of neurons and their metabolism) over one six between people with MS treated with EGCG at a dose of 400mg twice a day and people with MS treated with a matching sugar pill.

Full description

This will be a double blind placebo controlled trial of Theaphenon 95% (95% pure Epigallo-catechin-galleate [EGCG]) as a treatment for MS.

The primary outcome will be the changes in N-Acety-Aspartate (NAA) levels over six months. Secondary outcomes will be changes in brain atrophy over over six months. As an exploratory outcome we will correlate changes in NAA levels with free Plasma levels of EGCG 8 hours after the morning dose.

Exploratory outcomes include disability progression by Expanded Disability Status Scale (EDSS), multiple sclerosis functional composite components and a cognitive test battery.

Exclusion criteria

MS relapse within the 30 days prior to enrollment
A primary progressive form of MS.
Previous treatment prior to study entry as follows: complete radiation ablation of the bone marrow or anti-CD4 antibody treatment (Campath) at any time; mitoxantrone, cyclophosphamide, Natalizumab or other immunomodulatory or immunosuppressant therapies except the DMT's included in the inclusion criteria and methylprednisone for relapses within prior nine months.

Participants may not participate in any other clinical trial involving investigational agents during the study, or within six months prior to enrolling in the study.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to Polyphenon E, tea, or any of the inactive ingredients present in the active or placebo capsules, including gelatin.
History of allergic reactions to gadolinium or any other condition contraindicated for MRI.
Uncontrolled, clinically-relevant active illness (aside from MS) including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Any condition which would make the subject, in the opinion of the investigator, unsuitable for the study
