Study of Efficacy and Safety of Ligelizumab in Chronic Spontaneous Urticaria Patients Who Completed a Previous Study With Ligelizumab
Condition: Chronic Spontaneous Urticaria
MeSH terms: Urticaria; Chronic Urticaria
Intervention: Ligelizumab
Intervention description: For the first 12 weeks of treatment: i) participants transitioning from CQGE031C2302 (NCT03580369) and CQGE031C2303 (NCT03580356) previously treated with ligelizumab 72 mg LIVI s.c. Q4W were treated with the same dose regimen in a double-blind manner; ii) all other participants transitioning from CQGE031C2302 (NCT03580369) and CQGE031C2303 (NCT03580356) were treated with ligelizumab 120 mg LIVI s.c. Q4W in a double-blind manner; iii) participants transitioning from CQGE031C1301 (NCT03907878) and CQGE031C2202 (NCT03437278) were treated with ligelizumab 120 mg LIVI s.c. Q4W in an open-label manner.
Thereafter, all participants were switched to ligelizumab 120 mg s.c. PFS Q4W in an open-label manner and they were offered an opportunity to self-administer ligelizumab.
The longest possible treatment was 104 weeks, however this treatment might not be continuous and might span over a period of 156 weeks due to the possibility of entering the intervening observation period.

Summary:

      The purpose of this extension study was to establish efficacy and safety of ligelizumab. This
      was assessed in adult and adolescent chronic spontaneous urticaria (CSU) patients who had
      completed a preceding ligelizumab study and have relapsed, following treatment in these
      preceding studies, despite standard of care H1-antihistamine (H1-AH) treatment.

      This study also fulfilled the Novartis commitment to provide post-trial access to patients
      who had completed studies: CQGE031C2302 (NCT03580369), CQGE031C2303 (NCT03580356),
      CQGE031C2202 (NCT03437278) or CQGE031C1301 (NCT03907878).
