Brief summary: The purpose of this study is to explore whether DMF (Dimethyl Fumarate) or MMF (monomethyl fumarate) its main bioactive metabolite, is capable of entering the central nervous system in SPMS patients that are being treated with Tecfidera®. PK samples (pharmacokinetics - or the amount of study drug in blood) will be tested to compare with PK samples, the amount of study drug, in spinal fluid (CSF).

  1. Unable or unwilling to provide informed consent. (Subjects must provide separate informed consent for this study.)
  2. A MS relapse, as determined by the Investigator, which occurred within 90 days prior to screening, or the subject has not stabilized from a previous relapse prior to screening.
