Brief summary

1. Percent change from baseline in EASI score at Week 24

Detailed description

1. Proportion of patients with validated Investigator Global Assessment (vIGA) treatment success (IGA-TS) (defined as score 0/1 and a reduction ≥2 points from baseline), at Week 24, 2. Proportion of patients with EASI reduction of 75% (EASI75) relative to baseline score at Week 24, 3. Change and percent change from baseline in weekly average of the daily Peak Pruritus Numerical Rating Scale (PP-NRS) score at Week 24, 4. Proportion of patients with a 4-point improvement or greater from baseline in weekly average of the daily Peak Pruritus Numerical Rating Scale (PP-NRS) at Week 24, 5. Proportion of patients with EASI reduction of 50% (EASI50) relative to baseline score at Week 24, 6. Proportion of patients with EASI reduction of 90% (EASI90) relative to baseline score at Week 24, 7. Change from baseline in body surface area (BSA) at Week 24, 8. Incidence and severity of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) after first study drug dose on W0D1 until patient’s last visit., 9. Abnormality of clinical laboratory evaluations, 12-lead ECGs, vital signs, 10. Anti-ATI-045 antidrug antibody (ADA)
