结局指标
主要结局
Efficacy of S-777469 was assessed by Physician's Global Assessment (PGA) and Numerical Rating Scale (NRS)
时间窗: Change from baseline to 12 weeks
Physician's Global Assessment
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
时间窗: Baseline to 12 weeks
Safety, determined by Adverse event frequency and changes in laboratory values
次要结局
- 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(Changes from baseline to various pre-defined time-points during the 12 week study)
- Pharmacokinetic analysis of the concentration of unchanged parent drug (S-777469) in trough samples(From Baseline during Week 1)
