Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 In this extension study participants who achieve CRR or PRR status at Week 140 will be withdrawn from study treatment and will maintain the SoC medication as required.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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Study Treatment Withdrawal (cohort 1)

(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.

Group Type NO_INTERVENTION

No interventions assigned to this group

Open-Label Ianalumab (cohort 2)

(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.

Group Type EXPERIMENTAL

Ianalumab

Intervention Type DRUG

Ianalumab (VAY736) is a human monoclonal antibody (mAb) of the IgG1/κ-class, directed against B cells and binding to BAFF receptor (BAFF-R).
