The purpose of this study was to evaluate the safety and efficacy of ligelizumab in adult Japanese subjects with CSU, who remain symptomatic despite treatment with H1-antihistamines (AHs) at locally approved doses. The study population consisted of 66 male and female subjects aged ≥ 18 years who were diagnosed with CSU and who remained symptomatic despite the use of H1-AH. This was a Phase III multi-center, open-label, single arm study. There was a screening period of up to 28 days, a 52 week treatment period, and a 12 week post-treatment follow-up period.

Eligibility | Key Inclusion Criteria: - Signed informed consent must be obtained prior to participation in the study - Male and female subjects = 18 years of age at the time of screening - CSU diagnosis for = 6 months - Diagnosis of CSU refractory to H1-AH at approved doses at the time of Baseline (Visit 110, Day 1), as defined by all of the following: - The presence of itch and hives for = 6 consecutive weeks at any time prior to Visit 1 (Day -28 to Day -14) despite current use of non-sedating H1-AH (at locally approved doses) during this time period - UAS7 score (range 0-42) = 16 and HSS7 (range 0-21) = 8 during the 7 days prior to baseline (Visit 110, Day 1) - Subjects must be on H1-AH at only approved doses for treatment of CSU for starting at Visit 1 (Day -28 to Day -14) - Willing and able to complete a daily symptom electronic Diary (eDiary) for the duration of the study and adhere to the study visit schedules Key Exclusion Criteria: - History of hypersensitivity to any of the study treatments or excipients or to drugs of similar chemical classes (i.e. to murine, chimeric, or human antibodies) - Subjects having a clearly defined, predominant trigger of their chronic urticaria (CU) (chronic inducible urticaria (CINDU)) including - urticaria factitia (symptomatic dermographism), cold-, heat-, solar-, pressure-, delayed pressure-, aquagenic-, cholinergic-, or contact-urticaria - Diseases, other than chronic urticaria, with urticarial or angioedema symptoms such as urticarial vasculitis, erythema multiforme, cutaneous mastocytosis (urticaria pigmentosa), and hereditary or acquired angioedema (e.g., due to C1 inhibitor deficiency) - Subjects with evidence of helminthic parasitic infection as evidenced by stools being positive for a pathogenic organism according to local guidelines. All subjects will be screened at Visit 1. If stool testing is positive for pathogenic organism, the subject will not enter treatment period and will not be allowed to rescreen - Any other skin disease associated with chronic itching that might influence in the investigator's opinion the study evaluations and results (e.g. atopic dermatitis, bullous pemphigoid (BP), dermatitis herpetiformis, senile pruritus, etc) - Prior exposure to ligelizumab - Any H2 antihistamine, Leukotriene Receptor Antagonist (LTRA) (montelukast or zafirlukast) or H1 antihistamines use at greater than approved dose after Visit 1 Other protocol-defined inclusion/exclusion criteria may apply. |

Primary | Safety and Tolerability of Ligelizumab 120 mg q4w Treatment for 12 Months | Participants with treatment emergent adverse events (AEs) and serious adverse events (SAEs) summary for entire study (64 weeks)
An AE is any untoward medical occurrence, unfavorable, or unintended sign (including an abnormal laboratory finding), symptom, disease, or injury, temporally associated with the use of a marketed or investigational medicinal product, gene therapy, theragnostic product, or medical device, in patients, clinical-trial subjects, device users, or other persons, whether or not it is considered to be related to or due to the product. |

Secondary | UAS7 Change From Baseline Over Time | Mean change from baseline in UAS7 score over time is assessed as absolute change from baseline of UAS7 by visit up to end of study.
The Urticaria Activity Score (UAS) is the sum of Hive Severity Score (HSS) and Itch Severiry Score (ISS). The HSS has a scale of 0 (none) to 3 (> 12 hives/12 hours). A weekly score (HSS7) is derived by adding up the average daily scores of the preceding 7 days. So the range is 0-21; and negative change = improvement. The ISS also has a scale of 0 (none) to 3 (severe/difficult to tolerate). A weekly score (ISS7) is derived by adding up the average daily scores of the preceding 7 days. Score range is 0-21; and a negative change from baseline indicates improvement. The UAS7 is the sum of the HSS7 score and the ISS7 score, and has a possible range in score of 0-42. A negative change from baseline indicates improvement. |

Secondary | HSS7 Change From Baseline Over Time | The HSS has a scale of 0 (none) to 3 (> 12 hives/12 hours):
0 (None) (1-6 hives/12 hours) (7-12 hives/12 hours) (> 12 hives/12 hours) A weekly score (HSS7) is derived by adding up the average daily scores of the preceding 7 days. Score range is 0-21; and a negative change indicates improvement. |

Secondary | ISS7 Change From Baseline Over Time | The ISS has a scale of 0 (none) to 3 (severe):
0 None Mild (minimal awareness, easily tolerated) Moderate (definite awareness, bothersome but tolerable) Severe (difficult to tolerate) The ISS also has a scale of 0 (none) to 3 (severe/difficult to tolerate). A weekly score (ISS7) is derived by adding up the average daily scores of the preceding 7 days. So the score range of ISS7 is 0-21; and a negative change from baseline indicates improvement. |

Secondary | Percentage of Participants Who Achieved the Complete UAS7 = 0 Response Over Time | Assessed as the proportion of subjects achieving UAS7 = 0 over time.

Secondary | Change From Baseline in the Dermatology Life Quality Index (DLQI) | Assessed by absolute change from baseline of DLQI up to end of study. Score range is from 0-30:
