Study Endpoints

Primary Endpoints

Number of Participants With Treatment-emergent Adverse Events (TEAEs)
From start of extension study up to 14 weeks after last study-drug administration or end of study (whichever occurred earlier), assessed up to approximately 60 weeks

An AE was defined as any untoward medical occurrence (e.g., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a participant. TEAE included all AEs up to the last dose date plus 14 weeks or the end of the entire study (including the safety follow-up period), whichever occurred earlier. A patient with multiple severity ratings for an AE was only counted under the maximum rating. Additionally, a patient with multiple occurrences of an event was counted only once. The severity of AEs was assessed using the Common Terminology Criteria for Adverse Events, with the following grading system: Mild: usually transient in nature and generally not interfering with normal activities; Moderate: sufficiently discomforting to interfere with normal activities; Severe: prevented normal activities. A serious adverse event (SAE) was defined as any AE that required medical intervention, hospitalization, or results in death, disability, or a birth defect.

Treatment Arms

ArmTypeDescription
Arm 1: Iscalimab 600 mgEXPERIMENTALParticipants received 600 mg (2 injections of 300 mg/2 mL) of iscalimab subcutaneously weekly for the initial 3 weeks as loading doses, followed by a bi-weekly maintenance regimen at 600 mg (2 injections of 300 mg/2 mL).
Arm 2 - Iscalimab 300 mgEXPERIMENTALParticipants received one dose of 600 mg (2 injections of 300 mg/2 mL) of iscalimab subcutaneously on the first day of the extension study; then 300 mg weekly (1 injection of 300 mg/2 mL of iscalimab and 1 injection of 2 mL of placebo) for the next 2 weeks as loading doses. This was followed by a bi-weekly maintenance regimen of 300 mg (1 injection of 300 mg/2 mL of iscalimab and 1 injection of 2 mL of placebo). After the final database lock of the core study, participants underwent unblinding, leading to the discontinuation of placebo injections.
