Title: Phase 2 Randomized Placebo Controlled Trial of Polyphenon E in MS
Brief Summary: The hypothesis is that Polyphenon E 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 year between people with MS treated with Polyphenon E at a dose of 400mg twice a day and people with MS treated with a matching sugar pill.


Options:
A: Inclusion Criteria:

* At least 2 documented clinical attacks within the last 2 years prior to screening or one clinical attack in the years prior to screening (but not within 30 days prior to screening)

* Expanded Disability Status Scale (EDSS) score 0 to 5.5 inclusive

Exclusion Criteria:

* Has experienced a relapse within one month prior to the inclusion in the study.
* Has converted to secondary progressive MS.
* Has suffered from major depression or any other psychiatric disorder that would preclude safe participation in the protocol.

* Has alcohol or drug abuse.
* Has cardiac insufficiency, cardiomyopathy, significant cardiac dysrhythmia, unstable or advanced ischemic heart disease (NYHA III or IV), or malignant hypertension.
* Has renal insufficiency.
* Has ASAT or ALAT \> 2,5 x normal upper limit.
* Has leukopenia \< 2500 leukocytes per µl or thrombocytopenia \<100 000 thrombocytes per µl.
* Has any systemic disease, which can influence his/her safety and compliance, or the evaluation of the disability.
* Has thromboembolic disease that needs anticoagulative treatment.
* Have formerly shown severe reactions against study drug, interferon-beta or gadolinium (MRI contrast).
* Is breastfeeding or is pregnant.
C: Inclusion Criteria:

* Diagnosis of MS by McDonald criteria
* Relapsing-remitting MS or secondary progressive MS
* Stable therapy with Copaxone, Rebif, Betaseron or Avonex 30 mcg for at least six months
* EDSS Score less than or equal to 7.0
* Ages 18-60.
* Participants must have normal organ and marrow function as defined below:

  1. Leukocytes ≥3,000/µL
  2. Absolute neutrophil count ≥1,500/µL
  3. Platelets ≥100,000/µL
  4. Total bilirubin ≤local upper limit of normal
  5. AST (SGOT) ≤local upper limit of normal
  6. ALT (SGPT) ≤local upper limit of normal
  7. Creatinine ≤local upper limit of normal

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.

* 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.
