Eligibility
Inclusion criteria

Exclusion criteria
* Have clinically significant abnormalities in vital signs, physical examination, laboratory tests, chest X-ray/CT, or abdominal ultrasound during the screening period, which, as assessed by the investigator, may increase the participants' risk or affect the scientific validity of the study;(SD) * Females with a positive blood pregnancy test, breastfeeding females, or participants planning to become pregnant during the study period;(SD) * Any physiological or psychological condition or disease, as determined by the investigator, that could increase the risk, affect the participants' compliance, or impact the participants' ability to complete the study.(SD) * Chronic urticaria with a clear primary or sole trigger (chronic inducible urticaria);(MD and Phase 2) * Clearly defined predominant or sole trigger of their chronic urticaria (chronic inducible urticaria);(MD and Phase 2) * Other diseases with symptoms of urticaria or angioedema;(MD and Phase 2) * Other skin disease associated with chronic itching that might influence in the investigators opinion the study evaluations and results;(MD and Phase 2) * Pregnant or nursing (lactating) women.(MD and Phase 2)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence, severity and association with the study drug of adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation.(Phase 1) | SD:up to 7 days,MD:up to 35 days | Incidence, severity and association with the study drug of adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation. |
| Change from baseline in Weekly Urticaria Activity Score (UAS7) at Week 4 (Phase 2) | Week 4 | The Weekly Urticaria Activity Score (UAS7) is a simple scoring system to evaluate urticaria signs and symptoms. It is based on scoring wheals (hive severity score) and itch (itch severity score) separately on a scale of 0 (no signs/symptoms) to 3 (intense signs/symptoms) over 7 days. The final score is calculated by adding together the daily scores, which can range from 0 to 6, for 7 days. This results in a maximum total score of 42 (highest urticaria severity), and a minimum possible score of 0. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| AUC | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Area under the plasma concentration-time curve |
| t½ | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Terminal half-life |
| CL/F | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Apparent clearance |
| Vd/F | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Apparent volume of distribution |
| Cmax | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Maximum plasma concentration |
| Incidence, severity and association with the study drug of adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation.(Phase 2) | up to 16 weeks | Incidence, severity and association with the study drug of adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation;Clinically significant changes in physical examination and anamnesis, vital signs, ECG, safety laboratory will be reported under (S)AEs. |
| Change from baseline in Weekly Itch Severity Score (ISS7) at Week 12(Phase 2) | Week 12 | The severity of the itch was recorded by the participant daily in their electronic Diary, on a scale of 0 (none) to 3 (severe). A weekly score (ISS7) was derived by adding up the average daily scores of the 7 days preceding the visit. The possible range of the weekly score was therefore 0 - 21 (highest itch severity). |
| Change from baseline in Weekly Hives Severity Score (HSS7) at Week 12(Phase 2) | Week 12 | The hives (wheals) severity score, defined by number of hives, was recorded by the participant daily in their electronic Diary, on a scale of 0 (none) to 3 (\> 12 hives/12 hours). A weekly score (HSS7) was derived by adding up the average daily scores of the 7 days preceding the visit. The possible range of the weekly score was therefore 0 - 21 (highest hives activity). |
| Rac | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Accumulation ratio |
| Tmax | Day 1 up to Day 4 (SD), Day 1 up to Day 35 (MD) | Time to reach Cmax |
