Outcome Measures
Primary Outcome Measures
- Proportion of participants achieving Systemic Lupus Erythematosus Responder Index -4 (SRI-4) [Week 60]
SRI-4 response is defined as: Systemic Lupus Erythematosus Disease Activity Index - 2000 (SLEDAI-2K) reduction from baseline of ≥ 4 points No British Isles Lupus Assessment Group-2004 (BILAG-2004) worsening, defined as ≥ 1 new A or ≥ 2 new B items compared to baseline No worsening in Physician Global Assessment of Disease Activity (PhGA), defined as an increase of ≥ 0.3 from baseline on a 0 to 3 visual analog scale
Secondary Outcome Measures
- Proportion of participants with no moderate or severe BILAG flare [Baseline to Week 60]
Moderate BILAG flare is defined as 2 or more new BILAG-2004 B items compared to the previous visit; severe BILAG flare is defined as 1 or more new BILAG-2004 A items compared to the previous visit
- Proportion of participants maintaining between Week 36 and Week 60 a reduced corticosteroid (CS) dose of predniso(lo)ne ≤ 5 mg/day or ≤ baseline dose, whichever is lower [Week 36 to Week 60]

- Proportion of participants achieving BILAG-based Composite Lupus Assessment (BICLA) [Week 60]
BICLA response is defined as: Reduction of all baseline BILAG-2004 A to B/C/D and baseline B to C/D and no worsening in other organ systems defined as ≥ 1 new A or ≥ 2 new B items compared to baseline No worsening from baseline in SLEDAI-2K defined as an increase from baseline of > 0 points No worsening in PhGA defined as an increase of ≥ 0.3 from baseline on a 0 to 3 PhGA visual analog scale
- Proportion of participants achieving Lupus Low Disease Activity State (LLDAS) [Week 60]
LLDAS response is defined as: SLEDAI-2K ≤ 4, with no activity in major organ systems (renal, central nervous system (CNS), cardiopulmonary, vasculitis, fever) (Golder et al 2019) No new lupus disease activity compared with the previous assessment, defined as any new SLEDAI-2K component that was not present at the previous assessment PhGA (scale 0-3) ≤ 1 Current predniso(lo)ne (or equivalent) dose ≤ 7.5 mg daily Well tolerated standard maintenance doses of immunosuppressive drugs and approved biological agents
- Time to first occurrence of SRI-4 [Baseline to Week 60]
Time to first occurrence of SRI-4 from baseline to Week 60
- Proportion of participants achieving SRI-4 at Week 60 while maintaining between Week 36 and Week 60 a reduced CS dose of predniso(lo)ne ≤ 5 mg/day or ≤ baseline dose, whichever is lower [Week 36 to Week 60]
Achieving SRI-4 at Week 60 while maintaining between Week 36 and Week 60 a reduced CS dose of predniso(lo)ne ≤ 5 mg/day or ≤ baseline dose, whichever is lower
- Proportion of participants achieving SRI-6 [Week 60]
SRI-6 response is defined as: SLEDAI-2K reduction from baseline of ≥ 6 points No BILAG-2004 worsening, defined as ≥ 1 new A or ≥ 2 new B items compared to baseline No worsening in PhGA, defined as an increase of ≥ 0.3 from baseline on a 0 to 3 visual analog scale
- Proportion of participants maintaining between Week 24 and Week 60 a reduced CS dose of predniso(lo)ne ≤ 5 mg/day, or ≤ baseline dose, whichever is lower [Week 24 to Week 60]
Maintaining CS dose ≤ 5 mg/day or ≤baseline dose, whichever is lower, between Week 24 and Week 60
- Proportion of participants with Adverse Events (AEs) and Serious Adverse Events (SAEs), Clinical laboratory measurements, Vital signs [Baseline to Week 60]
To evaluate safety and tolerability of ianalumab s.c. monthly
- Incidence and titer of anti-drug (ianalumab) antibodies (ADAs) in serum over time [Baseline to Week 164]
To evaluate immunogenicity of ianalumab s.c. monthly
- Ianalumab concentration in serum during the treatment and follow-up [Baseline to Week 164]
