- Brief Summary
The main objective of this study was to evaluate the safety and efficacy of elsubrutinib, upadacitinib (UPA), and ABBV-599 (elsubrutinib/upadacitinib) High Dose and Low Dose combinations vs placebo for the treatment of signs and symptoms of Systemic Lupus Erythematosus (SLE) in participants with moderately to severely active SLE and to define doses for further development.

- anti-Smith+
-
SLEDAI-2K (SLE Disease Activity Index) ≥ 6 despite background therapy as reported and independently adjudicated (clinical score ≥ 4, excluding lupus headache and/or organic brain syndrome) at Screening:
- If 4 points of the required entry points are for arthritis, there must also be a minimum of 3 tender and 3 swollen joints.
- If participant has rash and Principal Investigator (PI) considers it to be attributable to SLE, participant must consent to skin photograph collection for adjudication.
- Score must be re-confirmed at the Baseline visit.
-

- Primary Outcome Measures
Name Time Method Percentage of Participants Achieving SLE Responder Index (SRI)-4 and Steroid Dose ≤ 10 mg Prednisone Equivalent Once a Day (QD) at Week 24 Baseline, Week 24 SLE Responder Index (SRI)-4 is defined as follows with all criteria compared to Baseline:
* ≥ 4-point reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score
* No worsening of the overall condition (\< 0.3 point increase in Physician's Global Assessment \[PhGA\])
* No new British Isles Lupus Assessment Group (BILAG) A or more than 1 new BILAG B disease activity scores (i.e., no organ system changes from baseline B/C/D/E to A and no more than 1 organ system changes from baseline C/D/E to B). A letter score is assigned to each organ system with following indications: A = severe, B = moderate, C = mild, D = inactive with prior history, and E = inactive with no history.
- Secondary Outcome Measures
Name Time Method Percentage of Participants Achieving British Isles Lupus Assessment Group (BILAG) Based Combined Lupus Assessment (BICLA) Response at Week 24 Baseline, Week 24 BICLA is a composite responder index. Achievement of BICLA response is defined as improvement in all initial A and B BILAG scores, with no more than one new BILAG B score without worsening of the overall condition (no worsening in Physician's Global Assessment \[PhGA\], \< 0.3 point increase) and no worsening of the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score.
Percentage of Participants Achieving SLE Responder Index (SRI)-4 at Week 24 Baseline, Week 24 SLE Responder Index (SRI)-4 is defined as follows with all criteria compared to Baseline:
* ≥ 4-point reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score
* No worsening of the overall condition (\< 0.3 point increase in Physician's Global Assessment \[PhGA\])
* No new British Isles Lupus Assessment Group (BILAG) A or more than 1 new BILAG B disease activity scores (i.e., no organ system changes from baseline B/C/D/E to A and no more than 1 organ system changes from baseline C/D/E to B). A letter score is assigned to each organ system with following indications: A = severe, B = moderate, C = mild, D = inactive with prior history, and E = inactive with no history.Percentage of Participants Achieving Lupus Low Disease Activity State (LLDAS) at Week 24 Baseline, Week 24 LLDAS is a state of low disease activity based on Systemic Lupus Erythematosus Disease Activity Index 2000 score (SLEDAI-2K score ≤4 excluding SLEDAI-2K activity in major organ systems), absence of SLE disease activity in major organ systems and new disease activity, Physician's Global Assessment (PhGA ≤1), and concomitant medication usage (steroid dose ≤7.5 mg QD and toleration of immunosuppressive drugs at standard maintenance doses).
Change From Baseline in Daily Prednisone Dose at Week 24 From Baseline to Week 24 Participants' current use of steroid therapy was assessed at each study visit, and the amount of daily prednisone was documented.
Number of Flares Per Patient-year by Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA) SLEDAI Flare Index Through Week 24 From Baseline to Week 24 The SELENA SLEDAI flare index defines mild/moderate or severe SLE flares using the SLEDAI score, definitions of worsening signs and symptoms, treatment changes, and Physician's Global Assessment of Disease Activity.
