Overview
Brief Summary
Participants who meet eligibility criteria will be randomized in a 1:1:1 ratio to receive a twice daily oral LNK01001 dose A or LNK01001 dose B or matching placebo for 12 weeks.
Detailed Description
The study was to include a 12-week double-blind treatment period. Participants who met eligibility criteria were to be randomized in a 1:1:1 ratio to one of the three treatment groups. Group 1:LNK01001 dose A (Day 1 to Week 12) Group 2:LNK01001 dose B (Day 1 to Week 12) Group 3: Matching placebo (Day 1 to Week 12)

Outcomes
Primary Outcomes
Percent Change from Baseline in Eczema Area and Severity Index (EASI) Score
Time Frame: week 12
EASI is a tool used to measure the extent (area) and severity of atopic eczema based on assessments of the head/neck, trunk, upper limbs and lower limbs. For each region the area score is recorded as the percentage of skin affected by eczema. For each region, the severity score is calculated as the sum of the intensity scores (scored as none \[0\], mild \[1\], moderate \[2\], or severe \[3\]) for redness (erythema, inflammation), thickness (induration, papulation, swelling - acute eczema), scratching (excoriation), and lichenification (lined skin, prurigo nodules - chronic eczema). The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The final EASI score is the sum of the 4 region scores and ranges from 0 to 72 where higher scores represent worse disease.
