Eligibility
Inclusion criteria
* Confirmed diagnosis of chronic inducible urticaria for at least 3 months. * Positive response following provocation using the TempTest or FricTest at Screening and Day 1.
Exclusion criteria
* History of diseases other than chronic inducible urticaria or chronic spontaneous urticaria with urticaria or angioedema symptoms, such as urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa), and hereditary or acquired angioedema. * Concurrent use of certain medications, including antihistamines. * Any clinically significant disease, or other skin disease or skin markings (e.g., extensive scarring, tattoos), that might confound the evaluation of safety or efficacy.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety and Tolerability | Day 1 to Week 6 | Safety will be assessed by the total number of subjects with at least one TEAE |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Total Fric Score (TFS) | Day 1 to Week 4 | The Total Fric Score represents the total number of linear wheals with a width of ≥3 mm induced following the Fric Test, from 0 to 4; 0 representing the minimum score (better outcome), and 4 representing the maximum score (worse outcome). A complete response is equal to a response of 0, where a subject began with at least a score of 1. A partial response is equal to a decrease of at least 2 points in the score (wheals), where a subject began with at least a score of 2. Partial responders may also be considered complete responders if their final score is equal to 0. |
| Change in Pruritus Severity at the Provocation Test Site | Day 1 to Week 4 | The Pruritus Severity is determined based on the Pruritus Numeric Rating Scale, or P-NRS. This is an 11-point scale completed by the subject prior to and approximately 10 minutes after completion of the provocation test, where 10 represents the worst itch (maximum), and 0 represents no itch (minimum) at the site of the urticaria provocation test. |
