Brief summary
This was a placebo controlled, phase 3 study designed to evaluate the efficacy and safety of ligelizumab in participants with chronic inducible urticaria who are inadequately controlled with H1-antihistamines
Detailed description
There are currently no approved therapies for patients with CINDU who remain symptomatic despite treatment with H1-antihistamines. The purpose of this study was to establish efficacy and safety of ligelizumab (QGE031) over placebo in participants with chronic inducible urticaria (CINDU) who remain symptomatic despite treatment with H1 antihistamine.

Eligibility
Inclusion criteria
* Confirmed CINDU diagnosis (as per guidelines) for symptomatic dermographism, cold urticaria or cholinergic urticaria for ≥ 4 months. * Diagnosis of CINDU (symptomatic dermographism, cold urticaria or cholinergic urticaria) inadequately controlled with H1-AH at local label approved doses at the time of randomization, as defined by all of the following: * Positive response (i.e development of symptoms) to triggers despite treatment with H1-AH * Positive response (i.e. development of symptoms) to provocation test on day of randomization * Participants must be able to physically perform the protocol defined provocation test specific to the participant's CINDU. * Cholinergic urticaria participants must show sweating in performing the pulse-controlled ergometry test on day of randomization. Participants with anhidrosis must not be included. * Willing and able to complete a daily symptom eDiary as per protocol requirement and adhere to the study visit schedules
Exclusion criteria
* History of hypersensitivity to any of the study drugs or its components or to drugs of similar chemical classes or to the provocation test or items used in provocation tests * Participants who have concomitant CSU at screening * Participants who have a familial form of the target CINDU that is being considered for the participant's inclusion in this study * Participants having a more defined other form of inducible urticaria than the target CINDU that is being considered for the participant's inclusion in this study * Diseases, other than chronic inducible urticaria, with urticarial or angioedema symptoms such as urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa) and hereditary or acquired angioedema (eg, due to C1 inhibitor deficiency). * Any other skin disease associated with chronic itching that might influence, in the investigator's opinion, the study evaluations and results (eg, atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, senile pruritus, etc.) or skin diseases associated with only wheals and no itch e.g asymptomatic dermographism * Prior exposure to ligelizumab, omalizumab and or other anti-IgE therapies

Outcome results
Change From Baseline in Critical Temperature Threshold in Participants With Cold Urticaria
The TempTest is used to induce itch and hives in participants with cold urticaria. Critical temperature threshold (CTT), as measured by the TempTest, determines the highest temperature sufficient for inducing symptoms.
Time frame: Baseline, Week 12
Population: RAN consisted of all randomized participants, regardless of whether or not they received a dose of drug. Participants were analyzed according to the treatment they were assigned.~Due to the limited number of participants who completed the primary endpoint timepoint (Week 12), no inferential statistical analysis was done for primary and secondary endpoints.
| Arm | Measure | Value (NUMBER) |
