Primary Outcome Measures:
  • Efficacy of S-777469 was assessed by Physician's Global Assessment (PGA) and Numerical Rating Scale (NRS) [ Time Frame: Change from baseline to 12 weeks ] [ Designated as safety issue: No ]
  • Safety was assessed by repeated clinical evaluation and evaluation of treatment-emergent adverse events. It included vital signs, medical history, concomitant medications, physical examination, 12-lead ECGs, and standard clinical laboratory safety tests [ Time Frame: Throughout the study ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Efficacy was assessed by PGA, NRS, Behavioral Rating Scale, Eczema Area and Severity Index Score, Investigator panel treatment-blind comparative review ratings of digital photography of affected areas, and Thymus and Activation-Regulated Chemokine [ Time Frame: At various pre-defined time-points throughout the study ] [ Designated as safety issue: No ]
  • Pharmacokinetic analysis focused on the concentration of unchanged parent drug (S-777469) in plasma. Plasma samples for analysis of S-77469 trough concentrations were obtained [ Time Frame: Week 1 ] [ Designated as safety issue: No ]
