Another oral agent has shown promise in a phase IIb trial for relapsing-remitting MS.  Ponesimod, a selective sphingosine 1-Phosphate Receptor 1 Agonist, reduced disease burden and activity as assessed by MRI and clinical measures (annualized relapse rates).   Safety and tolerability  were also assessed and proven to be good.   Larger trials are required to confirm the therapeutic utility of ponesimod in RRMS,  although choice is always good.  Read more in JNNP:
