A Phase 2 Study of MG-K10 in Chronic Spontaneous Urticaria
A Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Study to Evaluate the Efficacy and Safety of MG-K10 Humanized Monoclonal Antibody Injection in Subjects With Chronic Spontaneous Urticaria
This Phase 2 study evaluates the efficacy and safety of MG-K10 in participants with chronic spontaneous urticaria inadequately controlled by second-generation H1-antihistamines. Participants are randomized 1:1 to MG-K10 or placebo for 16 weeks, followed by an 8-week follow-up period.

Change from baseline in Urticaria Activity Score over 7 Days (UAS7) at Week 16
기간: Baseline to Week 16
|
UAS7 is the sum of daily itch severity and hive severity scores over 7 days, with total scores ranging from 0 to 42. The change from baseline at Week 16 will be compared between MG-K10 and placebo. |

Change from baseline in Itch Severity Score over 7 Days (ISS7) at Week 16
기간: Baseline to Week 16
|
The Itch Severity Score over 7 Days (ISS7) is the sum of the daily itch severity scores over 7 consecutive days. Each daily itch severity score ranges from 0 to 3, where 0 indicates no itch and 3 indicates intense itch. The total ISS7 ranges from 0 to 21, where 0 indicates no itch and 21 indicates the most severe itch. Higher ISS7 scores indicate worse itch severity. Change from baseline is calculated as the ISS7 at Week 16 minus the baseline ISS7; a negative change indicates improvement. |

|
|
Change from baseline in Hives Severity Score over 7 Days (HSS7) at Week 16
기간: Baseline to Week 16
|
The Hives Severity Score over 7 Days (HSS7) is the sum of the daily hives severity scores over 7 consecutive days. Each daily hives severity score ranges from 0 to 3, where 0 indicates no hives, 1 indicates fewer than 20 hives per 24 hours, 2 indicates 20 to 50 hives per 24 hours, and 3 indicates more than 50 hives per 24 hours or large confluent areas of hives. The total HSS7 ranges from 0 to 21. Higher HSS7 scores indicate greater hives severity and worse outcome. Change from baseline is calculated as the HSS7 at Week 16 minus the baseline HSS7; a negative change indicates improvement. |
