Phase III Extension Study of Efficacy and Safety of Ianalumab With or Without Study Treatment Withdrawal in Participants With Lupus Nephritis (SIRIUS-LN Extension)
- Registration Number
- NCT06711887
- Lead Sponsor
- Novartis Pharmaceuticals
- 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.
- Detailed Description
The SIRIUS-LN extension study is a 2-year open-label extension study for participants who have completed the treatment periods (blinded Treatment Period-1 and blinded Treatment Period-2) of the SIRIUS-LN core study on double-blind or open-label study treatment.
Investigators will use their clinical judgment to decide if it is beneficial for participants to continue with the extension study. In this extension study participants who achieve CRR or PRR status at Week 140 will be withdrawn from study treatment and will maintain the SoC medication as required. These 2 additional years in the extension study will allow to measure sustained remission, flares and safety off-study treatment. However, in the event of renal flares during the extension study, these participants who withdraw study treatment will have the option to receive open-label ianalumab.

Group Intervention Description Open-Label Ianalumab (cohort 2) Ianalumab (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.
- Primary Outcome Measures
Name Time Method For cohort 1: Incidence of renal flare, escalation of immunosuppressive medication, or death Between Week 144E1 and Week 248 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
Cohort 2: Number of participants with Treatment Emergent Adverse Events (TEAE) as assessed by CTAE v4.0 From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study 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
Cohort 2: Number of participants with Serious Adverse Events (SAE) as assessed by CTCAE v4.0 From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study 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
Cohort 2: Number of participants with clinically significant abnormal vital signs From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study Cohort 2: Analysis of the vital sign measurements using summary statistics for the change from baseline for each post-baseline visit will be performed
Cohort 2: Number of participants with clinically significant laboratory evaluations. From the start of treatment in the SIRIUS-LN core study to EOS (up to week 352) of the extension study 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.
