Clinical Trial Summary

The purpose of the study is to investigate the mechanism of action for ligelizumab (QGE031) treatment in patients with chronic urticaria. The study has two parts. The study population will consist of approximately 68 male and female healthy volunteers and patients. In Part 1, approximately 20 healthy volunteers and patients with chornic urticaria will be enrolled. In Part 2 approximately 48 patients with chronic urticaria (spontaneous chronic urticaria, cholinergic urticaria or cold urticaria). Part 1 consists of a screening period up 2 weeks and a visit with skin tests; there is no treatment taken in Part 1. Part 2 is randomized, subject, investigator and sponsor blinded. It consists of a screening period up to 4 weeks, a 16 week treatment period and a 12-week follow-up period after last treatment. A follow-up call at Week 32 will be performed via telephone.

• History of allergies or allergy to the challenge substances including ciprofloxacin, icatibant, other quinolones or excipients of the substances being used in the study.
• Recent (within the last three years) and/or recurrent history of autonomic dysfunction (e.g. recurrent episodes of fainting, palpitations, etc.).
• Donation or loss of 450 mL or more blood within eight weeks prior to initial dosing, or longer if required by local regulations. CSU and CINDU patients (cold and cholinergic urticaria)
• History of allergies or allergy to the challenge substances including ciprofloxacin, icatibant (Part 1 only), other quinolones or excipients of the substances being used in this study.
• Contraindications to or hypersensitivity to antihistamines (such as fexofenadine, loratadine, cetirizine, rupatadine, bilastine) or epinephrine or any of the ingredients.
• History or presence of renal disease and/or estimated glomerular filtration (eGFR) rate of < 35 mL/min as calculated by the CKD-EPI formula at Screening.
• For subjects who enter Part 2: Patients with a history of or a risk of parasite infections (recent stay in tropical/subtropical areas with low hygiene standards). To allow enrollment of a patient at risk perform stool examinations for ova or parasites and demonstrate absence of infection first.
• Diseases with possible signs and symptoms of urticaria or angioedema such as urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa), and hereditary or acquired angioedema (e.g. due to C1 inhibitor deficiency). CSU patients • Clearly defined underlying etiology for chronic urticaria symptoms other than CSU. This includes the following: CSU patients should not have inducible urticaria forms impacting their daily symptoms in a relevant way, such as but not limited to urticaria factitia, cold-, heat-, solar-, pressure-, delayed pressure, aquagenic-, cholinergic-, or contact-urticaria. CINDU patients (cold and cholinergic urticaria)
• Clearly defined underlying etiology for chronic urticaria symptoms other than CINDU. This includes the following: CINDU patients should not have spontaneous urticaria impacting their symptoms in a relevant way. Other protocol-defined inclusion/exclusion criteria may apply .

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part 1: Wheal and erythema size after skin prick test with several different ciprofloxacin and icatibant concentrations.	Size of the wheal and erythema in mm will be measured after the skin prick and intradermal tests are performed. Different dilution steps will be applied (to differentiate Chronic Spontaneous Urticaria patients and healthy controls) for ciprofloxacin and icatibant to determine the conditions to be used in Part 2.	At Day 1
Primary	Part 2: Change in wheal size after challenge procedure from Day 1 (pre-dose) to week 16.	Size of wheal in mm2 after skin prick test and autologous serum skin test will be measured.	Day 1 and Week 16
Secondary	Part 2: Urticaria Control Test	The Urticaria Control Test (UCT) is a questionnaire that assesses the extent of the disease control over the previous 4 weeks. It consists of 4 questions, each rated from 0 to 4 points. Subsequently, the scores for all 4 questions are summed up. The minimum and maximum UCT scores are 0 and 16, with 12 points or higher indicating controlled disease, and 16 points indicating complete disease control.	Day 1, Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28
Secondary	Part 2: Weekly Urticaria Activity Score	Chronic Spontaneous Urticaria (CSU) patients: The Urticaria Activity Score (UAS) is evaluated in the screening period and throughout the study. It records each morning and evening on a daily basis symptoms of itch and hives into a patient diary. The UAS is a composite score with numeric severity intensity ratings on a scale of 0 - 3 for the number of wheals (hives) and the itch intensity. The UAS7 is the sum of the daily UAS scores over 7 days. UAS7 values range from 0 to 42, with higher values indicate higher disease activity.	Throughout the study (to 28 weeks)
Secondary	Part 2: Cholinergic Urticaria Activity score	Cholinergic urticaria patients: Cholinergic Urticaria Activity score (CholUAS) is a questionnaire that records each evening on a daily basis symptoms of itch and hives and the general assessment of disease severity into a patient diary. The CholUAS is a composite score with numeric ratings on a scale of 0 - 3 for the intensity of wheals (hives), the itch intensity, and the overall assessment of the disease severity. The total score is a sum of scores multiplied with the score for the trigger. The CholUAS7 is the sum of the daily CholUAS scores over 7 days. Higher values indicate a higher disease activity.	Day 1 to Week 28
Secondary	Part 2: Chronic Urticaria Quality of Life questionnaire	CSU patients: The Chronic Urticaria Quality of Life questionnaire (CU-Q2oL) is a questionnaire that measures the relative burden of chronic urticaria on subjective well-being. It consists of 23 questions in 3 domains (symptoms, general impairment, difficulties and problems due to urticaria). with a total score of 0 to 100 %. Higher scores indicate higher impairment in quality of life.	Day 1, Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28
Secondary	Part 2: Angioedema control test	CSU patients with angioedema: Angioedema Control Test (AECT) is a questionnaire that assesses the extent of the symptom control (angioedema). It consists of 4 questions, each rated from 0 to 4 points. Subsequently, the scores for all 4 questions are summed up. The minimum and maximum AECT scores are 0 and 16, with 10 points or higher indicating controlled disease, and 16 points indicating complete disease control.	Day 1, Week 16, Week 28
Secondary	Part 2: Cholinergic Urticaria Quality of Life questionnaire	Cholinergic patients: The Cholinergic Urticaria Quality of Life questionnaire (Chol-Q2oL) is a questionnaire that measures the relative burden of cholinergic urticaria on subjective well-being. The questionnaire consists of 28 items, each item being scored between 0 and 4. Higher scores indicate higher impairment in quality of life.	Day 1, Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28
Secondary	Part 2: Provocation test for cholinergic patients	Cholinergic patients: Time from onset of sweating and urticaria symptoms after an exercise on a stationary bicycle.	Day 1, Week 4, Week 16, Week 28
Secondary	Part 2: Temperature trigger test for cold urticaria patients	Cold urticaria patients: The temperature that will provoke the formation of wheals will be assessed.	Day 1, Week 4, Week 16, Week 28
Secondary	Part 2: Number of patients with adverse events	Part 2: Safety and tolerability	Throughout the study (to 28 weeks)
