Brief Summary
The purpose of this 2-year extension study is the evaluation of the efficacy and safety
- 1.after study treatment withdrawal in patients with lupus nephritis (LN) who achieved response (complete renal response \[CRR\] or partial renal response \[PRR\]) on double-blind treatment at the end of the SIRIUS-LN core study, and
- 2.of open-label ianalumab 300 mg treatment in patients who, at the end of the SIRIUS-LN core study, were either already receiving ianalumab open-label treatment or did not meet CRR/PRR criteria on double-blind treatment at the end of the SIRIUS-LN core study.

Outcome Measures
Primary Outcomes (5)
For cohort 1: Incidence of renal flare, escalation of immunosuppressive medication, or death
Cohort 1: To estimate the incidence of renal flare, escalation of immunosuppressive medication, or death following study treatment withdrawal in participants who completed the SIRIUS-LN core study on double-blind treatment and achieved CRR or PRR at Week 140 of the core study
Between Week 144E1 and Week 248
Cohort 2: Number of participants with Treatment Emergent Adverse Events (TEAE) as assessed by CTAE v4.0
Cohort 2: To assess the safety and tolerability of ianalumab for participants who, at the end of the SIRIUS-LN core study, were either already receiving ianalumab open-label treatment or did not meet CRR/PRR criteria on double-blind treatment at the end of the SIRIUS-LN core study
From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study
Cohort 2: Number of participants with Serious Adverse Events (SAE) as assessed by CTCAE v4.0
Cohort 2: Incidence of SAEs, from the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study
From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study
Cohort 2: Number of participants with clinically significant abnormal vital signs
Cohort 2: Analysis of the vital sign measurements using summary statistics for the change from baseline for each post-baseline visit will be performed
From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study
Cohort 2: Number of participants with clinically significant laboratory evaluations.
Cohort 2: The summary of laboratory evaluations will be presented for two groups of laboratory tests (hematology and serum chemistry). Descriptive summary statistics for the change from baseline to each study visit will be presented. These descriptive summaries will be presented by test group, laboratory test and treatment group.
From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study
Secondary Outcomes (6)
Cohort 1: Number of participants with Treatment Emergent Adverse Events (TEAE) as assessed by CTCAE v4.0
From the start of treatment in the SIRIUS-LN core study up to EOS (week 248) of the extension study
Cohort 2: Incidence and titer of anti-ianalumab antibodies in serum (ADA assay)
from Week 144E1 up to Week 248
Cohort 2: Ianalumab concentration in serum using a validated ELISA
from Week 144E1 up to Week 248
Cohort 1: Number of participants with Serious Adverse Events (SAE) as assessed by CTAE v4.0
From the start of treatment in the SIRIUS-LN core study up to EOS (week 248) of the extension study
Cohort 1: Number of participants with clinically significant abnormal vital signs
From the start of treatment in the SIRIUS-LN core study up to EOS (week 248) of the extension study
- +1 more secondary outcomes
Study Arms (2)
Study Treatment Withdrawal (cohort 1)
NO INTERVENTION(Cohort 1): Study Treatment-Withdrawal group. Participants who received blinded study treatment in the core study and achieve CRR or PRR at Week 140 in the core study will enter the extension study and discontinue study treatment while maintaining standard of care (SoC) medication, as required. If renal flare criteria are met, participants will be eligible to receive open-label ianalumab.
Open-Label Ianalumab (cohort 2)
EXPERIMENTAL(Cohort 2): Open-Label Ianalumab group: Participants who received blinded study treatment throughout the core study and did not achieve CRR or PRR at Week 140 of the core study, or who had switched to open-label ianalumab during the core study, will be eligible or will continue to receive open-label ianalumab in the extension study.
Interventions
Ianalumab (VAY736) is a human monoclonal antibody (mAb) of the IgG1/κ-class, directed against B cells and binding to BAFF receptor (BAFF-R).
