Study to Evaluate the Feasibility of [18F]Florbetapir PET for Assessment in MS Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the feasibility of [18F]Florbetapir positron emission tomography (PET) for assessment of demyelination in the patients with relapsing remitting multiple sclerosis.

Detailed Description
-----------------
The underlying goal of this study is to assess the feasibility of [18F]Florbetapir as an imaging tool to detect demyelination in the brain of MS research participants and compare to similarly aged healthy subjects.

Inclusion Criteria (MS Subjects): Have a diagnosis of relapsing remitting MS according to the 2010 MacDonald Criteria Have at least 10 demyelinating lesion on brain MRI with the following characteristics: Hypointense on T2 weighted images with FLAIR Exclusion Criteria (for all subjects): The subject has clinically significant abnormal laboratory value and/or clinically significant unstable medical or psychiatric illness The subject has evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, alternative neurological (other than RRMS), immunodeficiency, pulmonary, or other disorder or disease. Women who are pregnant or actively breastfeeding The subject has any disorder that may interfere with drug absorption, distribution, metabolism, or excretion (including gastrointestinal surgery) The subject has participated in another clinical study within the previous 30 days Renal impairment with a creatine clearance <80mL/minute at screening (creatine clearance estimated by Cockcroft-Gault equation) The subject is scheduled to have a major surgery or procedure during the time of the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Number of Lesions Detected by [18F]Florbetapir PET | This study demonstrates the feasibility of[18F]Florbetapir PET for identifying demyelinating lesions in relapsing-remitting MS patients. It was expected that lesion size played a factor in identifying white matter lesions with those smaller than 5 mm less evident on PET. Using spherical volumes of interest the extent of reduction in the white matter uptake can be reliably quantified. This requires careful attention to techniques for sampling in both the lesions and white matter control regions for the subject. | 1 year |
