Ponesimod for the treatment of relapsing multiple sclerosis.

Published peer-reviewed data on long-term safety and efficacy are still lacking but have been collected and regulatory authorities expressed a favorable opinion to market access. At present, we believe that ponesimod has little chance of becoming a leading treatment for RMS due to the availability of many alternative options and the timing of market access. Given its favorable risk-benefit and convenience profile, however, ponesimod might become a leading option among S1P receptor modulators used for RMS.
