A Safety Study of Combination Treatment With Avonex and Zocor in Relapsing Remitting Multiple Sclerosis
A Safety Study of Combination Treatment With Avonex and Zocor in Relapsing Remitting Multiple Sclerosis
The purpose of this study is to determine if using Avonex in combination with Zocor is a safe
 and effective therapy for subjects with relapsing remitting multiple sclerosis.
Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the Central Nervous
 System (CNS). There are many forms of MS; althoughthe majority are Relapsing Remitting (RRMS)
 representing approximately 80% of the cases. The disease appears to be more inflammatory in
 RRMS as manisfested by an increase inGadolinium enhancement on MRI and an increase in
 inflammatory bioassay markers.

 Zocor is in a class of drugs (statins) that are used to lower cholesterol. Statins also have
 an anti-inflammatory effect on the CNS. Zocor has been shown in a small clinical trial to
 reduce the number of new MRI-detected brain lesions over a six month treatment period in
 patients with RRMS. This study is to evaluate the safety of combining Avonex with Zocor for a
 a period of fourteen months in patients with RRMS and to evaluate the effect of treatment on
 new or enlarging lesions as measured by MRI.
Inclusion Criteria:

 1. Male or non-pregnant females age 18-55 who have clinically and laboratory definite
 relapsing-remitting MS using the MacDonald criteria.

 2. Subjects must be taking some form of interferon therapy (Rebif, Avonex or Betaseron)
 for a duration of 12 months with documented breakthrough disease as defined:

 -  or = 1 documented clinical relapse in past 12 months while on interferon therapy.
 For eligibility, a pre-study relapse is defined as neurologic symptoms and signs
 documented by review of the history with the subject or in the medical record, of
 sufficient severity and duration to be determined by the investigator as
 consistent with an acute MS relapse.

 The relapse does not need to have been treated to qualify. the timing of the relapse
 is defined based on the onset of symptoms.

 OR

 > or = 1 documented Gd-enhancing lesion on cranial or spinal MRI. The presence of a
 Gd-enhancing lesion must be documented either by a report in the medical record or
 review of the films by the investigator.

 3. The Kurtzke EDSS score must be between 0- 5.0.

 4. All subjects must give written consent prior to evaluation and testing.

 Exclusion Criteria:

 1. Subjects with primary or secondary progressive MS.

 2. Female patients may not be pregnant, attempting pregnancy or breastfeeding.

 3. Female subjects must use an acceptable form of contraception during the study as
 defined by the investigators. The rhythm method is not to be used as the sole method
 of contraception.

 4. Subjects unwilling or unable to give informed consent.

 5. Subjects that are NAB+ (titers > or = 20).

 6. Abnormal baseline blood test exceeding any of the limits defined below:

 1. ALT or AST > 2x upper limit of normal (ULN)

 2. CPK > 2x upper limit of normal (ULN)

 3. Total WBC < 3,000/mm3

 7. No chronic infections (including HIV and Hepatitis B/C) may be present.
