Results

No baseline levels of biomarkers were significantly associated with EASI reduction.
There were significant associations of baseline levels of LDH, Soluble IL-2 R, TARC, CCL22, CCL27, and CCL18 with POEM reduction. There were also significant associations of baseline levels of LDH, Soluble IL-2R, and TARC with pruritus-NRS reduction. Moreover, there were significant associations of baseline levels of Soluble IL-2R and TARC with uncomfortable skin-NRS reduction.

Outcome measures

The serial changes in the EASI, POEM, pruritus-NRS, uncomfortable-skin-NRS, and
treatment-satisfaction-NRS.
The mean EASI score at baseline was 26.6 (SD: 9.9). However, the mean value in Week 16 was 4.8 (SD: 4.9). The rate of change in the EASI score was -81.4%. There were also slight decreases in the POEM, pruritus-NRS, and uncomfortable-skin-NRS between the time of baseline and Week 16.
The rates of change from the values at baseline were -59.3%, -57.0%, and -57.2%, respectively. Concerning the treatment-satisfaction-NRS, there was a slight increase between the time of baseline and Week 16. The rate of change in the treatment satisfaction- NRS from the value at baseline was 109.8%.
