Abstract

The treatment difference in the LS mean from baseline in the ISS7 was −0.80 (90% confidence interval [CI]: −1.64, 0.05), which lies within the predefined equivalence margin (±2.1) [Supplementary Table 2, http://links.lww.com/CM9/C413]. In the SYN008 and omalizumab groups, at week 12, the LS mean (SE) changes from baseline in the Dermatology Life Quality Index (DLQI) were −11.09 (0.37) and −11.00 (0.37), with an LS mean treatment difference of −0.08 (95% CI: −1.11, 0.95) [Supplementary Table 2, http://links.lww.com/CM9/C413]. During the 24-week study period, 118 (69.4%) patients in the SYN008 group and 120 (69.8%) patients in the omalizumab group experienced at least one treatment-emergent adverse event (TEAE). [5] The main limitation of this phase III study is the short total observation period of 24 weeks, with 12 weeks each for treatment and follow-up durations. [...]a long-term observational study in which more CSU patients and more data are available may be needed to further evaluate the efficacy and safety results of this study.
