Outcomes

Primary Outcomes

Achievement of British Isles Lupus Assessment Group Disease Activity Index 2004 (BILAG 2004)-based Composite Lupus Assessment (BICLA) response at Week 48

A study participant is a BICLA responder if all of the following is fulfilled: a. BILAG 2004 improvement without worsening, defined as BILAG 2004 Grade As at Baseline improved to B/C/D, BILAG 2004 Grade Bs at Baseline improved to C/D, and no BILAG 2004 worsening in other BILAG 2004 organ systems (that had BILAG 2004 Grade C/D/E at Baseline) such that there are no new BILAG 2004 Grades A nor greater than 1 new BILAG 2004 Grade(s) B; and b. No worsening in the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI- 2K) total score compared to Baseline (defined as no increase in SLEDAI-2K total score); and c. No worsening in the Physician's Global Assessment of Disease (PGA) compared to Baseline defined as ≤10 mm increase on a 100 mm visual analog scale Escape treatment intervention as indicated by investigator until the assessment time point will be defined as an intercurrent event for the primary endpoint leading to non-response from the day after the event onward.

Time frame: Week 48

Secondary Outcomes

Achievement of SRI 4 response at Week 48

The Systemic Lupus Erythematosus Responder Index-4 (SRI 4) define responders as (ie, all criteria must be met): * Reduction in SLEDAI-2K score of ≥4 * No shift from BILAG 2004 Grade B, C, D, or E to A post-Baseline * No more than 1 shift from BILAG 2004 Grade C, D, or E to B post-Baseline * No worsening in the PGA compared to Baseline score; "no worsening" is defined as either no worsening or worsening \<10% of the full 100 mm visual analog scale (VAS).

Time frame: Week 48

Achievement of prevention of severe BILAG flares (severe BILAG flare-free) through Week 48

Severe BILAG flare is defined as a BILAG 2004 Grade A in any system due to individual items that are new or worse qualifying for the Grade A. Determination of items that are new or worse qualifying for the Grade A will be according to the supplementary information for the numerical scoring of the BILAG-2004 index.

Time frame: Week 48

Achievement of LLDAS at Week 40 and maintaining LLDAS at Weeks 44 and 48

Low lupus disease activity state (LLDAS) is defined as: * No significant disease activity as per Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K); SLEDAI-2K score ≤4 with no activity in major organ systems (renal, central nervous system (CNS), cardiopulmonary, vasculitis, fever) * No new and/or worsening disease activity defined as no SLEDAI-2K component documented as present that was not documented present at previous visit * Physician's Global Assessment of Disease (PGA) ≤33 mm * Prednisone equivalent systemic dose for systemic lupus erythematosus (SLE) indication ≤7.5 mg per day * Stable standard maintenance doses of immunosuppressive drugs as allowed by protocol

Time frame: Week 40 to Week 48

Change from Baseline to Week 48 in the FATIGUE-PRO Total score

The FATIGUE-PRO (Fatigue patient-reported outcome) is a PRO instrument measuring fatigue, a core symptom of SLE, developed using qualitative and quantitative research conducted in patients with SLE. It is composed of 31 items covering 3 domains: Physical Fatigue (items 1-9), Mental and Cognitive Fatigue (items 10-20), and Susceptibility to Fatigue (items 21-31). The study participant is asked to score each fatigue item based on how frequently they experienced the item during the past 7 days using the following response options: 1=none of the time; 2=a little of the time; 3=some of the time; 4=most of the time; 5=all of the time.
