Summary:

      This single-center, open-label, non randomized Phase I study is being conducted to
      investigate the pharmacokinetics, mass balance and metabolite profiling and identification
      after a single oral dose of 100mg of [14C]-MD1003 in 6 healthy males subjects. The
      radioactivity will be followed in the blood, urine and faeces to study MD1003 metabolism.
