Current Primary Outcome Measures  ICMJE
 (submitted: July 14, 2014)
TTR stabilization [ Time Frame: 24 hours and 32 hours ]
TTR stabilization will be measured by determining the concentration of tetrameric TTR after denaturation. The ratio of TTR tetramer after denaturation / TTR tetramer before denaturation of plasma samples from treated subjects will be compared to their baseline ratio. TTR stabilization will be determined as percentage of the baseline ratio.

Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: July 14, 2014)
  • Pharmacodynamics assessment [ Time Frame: 24 hours and 32 hours ]
    Determine the minimal molar ratio SOM0226:TTR that must be reached in plasma to confer maximal TTR stabilization
  • Safety [ Time Frame: 24 hours ]
    Drug safety will be assessed by blood biochemistry and hematology analysis, patient exploration and adverse event reporting
