Protocol-defined topical and systemic standard of care background treatments.

SLE SRI-4 composite response is a composite response of at least a 4 point reduction in SLEDAI-2K, no BILAG-2004 worsening, defined as no new A or <= 1 new B items compared to baseline, no worsening in PGA (> 10% increase from baseline). Sustained reduction in oral GC dose at Week 52 is defined as achieving <= 5 mg/day oral prednisone (or equivalent) AND no increase of that dose from Week 32 through Week 52.

LLDAS is defined as follows: SLEDAI-2K <= 4, with no activity in major organ systems (renal, central nervous system, cardiopulmonary, vasculitis, fever) and no hemolytic anemia or gastrointestinal activity measured as maintaining a D (no disease activity but suggests the system had previously been affected) or E (no current or previous disease activity) score in BILAG gastrointestinal body system, no new lupus disease activity compared with the previous assessment measured as no new or worsening individual BILAG parameters, physician's global assessment of disease activity <= 1 on a 3-point visual analog scale from no disease activity to severe disease activity, a current prednisolone (or equivalent) dose <= 7.5 milligram (mg) daily and well-tolerated standard maintenance doses of immunosuppressive drugs and approved biological agents.

Percentage of participants with < 2 active joints at Week 52 in participants with >= 2 active joints at baseline will be reported.

Lupus symptoms joint pain score at Week 52 will be reported.

Percentage of participants achieving sustained reduction in oral GC dose at Week 52 in participants treated with oral GC >5 mg/Day prednisone (or equivalent) at baseline will be reported.

FACIT-Fatigue version 4.0 is a 13-item questionnaire that assesses participant-reported fatigue and its impact upon daily activities and function over the past 7 days. Participants will be asked to answer each question using a 5-point Likert scale (0=Not at all; 1=A little bit; 2=Somewhat; 3=Quite a bit; and 4=Very much). FACIT-Fatigue has a total score range from 0 to 52, with 0 being the worst possible score and 52 the best.

A participant has a flare-free status if no flare has been reported during the 52-week treatment period. A flare was defined as either 1 or more new BILAG-2004 A (severe disease activity) or 2 or more new BILAG-2004 B (moderate disease activity) items compared to the previous visit.

SLE SRI-4 composite response is a composite response of at least a 4 point reduction in SLEDAI-2K, no BILAG-2004 worsening, defined as no new A or <= 1 new B items compared to baseline, no worsening in PGA (> 10% increase from baseline). Autoantibody high participants is defined as participants with high autoantibody at baseline.
