  2. Clinical Trial: Fenebrutinib

    A study to evaluate the effectiveness and safety of fenebrutinib on disability progression and relapse rate. Eligible participants will be randomly assigned to receive either fenebrutinib or teriflunomide. Some may then  receive fenebrutinib during an open label extension.
  3. Clinical Trial: Comparing Experimental Fenebrutinib to Aubagio® in Relapsing MS

     Investigators in the U.S. and abroad are recruiting a total of 1468 people with relapsing forms of MS for two separate studies comparing investigational oral fenebrutinib with Aubagio ® (teriflunomide, Sanofi Genzyme). The studies – also called FENhance – are sponsored by F....
  4. Clinical Trial: Comparing Experimental Fenebrutinib to Ocrevus® in Primary Progressive MS

    Investigators in the U.S. and abroad are recruiting 946 people with primary progressive MS for a study comparing investigational oral fenebrutinib with  Ocrevus ®  (ocrelizumab - Genentech, a member of the Roche Group). The study – also called FENtrepid – is sponsored by F. H...

  8. Clinical Trial:IMU-838

    Following a 4-week screening period, participants will take either oral IMU-838 or placebo for a period of 72 weeks during the main period of the study. Participants may need to stop taking certain MS medications during the trial.  An MRI scan will be needed during screening p...
  9. Clinical Trial: Improving New Learning and Memory in MS

    The Kessler Foundation is currently recruiting for a study on memory. Participants will be compensated.. The study involves paper-and-pencil testing and is intended to assess the efficacy of learning and memory techniques within the Multiple Sclerosis population. Additionally,...
  10. Clinical Trial: Ocrelizumab for Preventing MS in Individuals With Radiologically Isolated Disease

    “Radiologically isolated syndrome” (RIS) is diagnosed when it is discovered that someone has brain MRI abnormalities similar in appearance and location to abnormalities seen in people with MS. People with RIS are typically otherwise healthy and without any symptoms common for ...
