Program to Assess Adverse Events and Change in Disease Activity of Oral Upadacitinib in Adult Participants With Moderate to Severe Systemic Lupus Erythematosus

Eligibility Criteria

• * Clinical diagnosis of systemic lupus erythematosus (SLE) at least 24 weeks prior to screening as defined by the 2019 European Alliance of Associations for Rheumatology (EULAR)/ American College of Rheumatology (ACR) classification criteria for SLE.
• * At Screening, must have at least one of the following:
• * antinuclear antibody (ANA) positive (titer \>= 1:80)
• * anti-double stranded deoxyribonucleic acid (dsDNA) positive
• * anti-Smith positive
• * Hybrid systemic lupus erythematosus disease activity index (hSLEDAI) \>= 6, of which \>= 4 points are clinical (not based on laboratory criteria), independently reviewed by the MCDR at Screening. Clinical hSLEDAI score (not based on laboratory criteria) must be re-confirmed as \>= 4 at the Baseline visit. Lupus headache or organic brain syndrome do not count towards the hSLEDAI points required for eligibility but should be documented on the hSLEDAI if present.
• * Physician's Global Assessment (PhGA) \>= 1 during screening period.
• * On stable background treatment for \>= 60 days prior to Baseline (with the exception of oral corticosteroid \[OCS\], which must be at a stable dose for \>=14 days prior to Baseline) with
• * antimalarial(s) \[hydroxychloroquine \<= 400 mg daily, chloroquine \<= 500 mg daily, quinacrine \<= 100 mg daily\];
• * and/or prednisone (or prednisone-equivalent) (\<= 20 mg daily);
• * and/or no more than 1 of the following: azathioprine (\<= 150 mg daily), 6-mercaptopurine (\<= 150 mg daily), mycophenolate mofetil (\<= 2 g daily), mycophenolate sodium \<= 1,440 mg/day, leflunomide (\<= 20 mg daily), cyclosporine, tacrolimus, voclosporin (\<= 23.7 mg twice daily), methotrexate (\<= 25 mg weekly), or mizoribine (\<= 150 mg daily).
• * Class III/IV lupus nephritis that was treated with induction therapy within the 6 months prior to Screening.
• * Active neuropsychiatric SLE (excluding lupus headache) within the 6 months prior to Screening.
• * SLE overlap syndromes including, but not limited to, rheumatoid arthritis, systemic sclerosis, polymyositis, dermatomyositis, or mixed connective tissue disease (Sjögren's syndrome is permitted).
• * Antiphospholipid syndrome and prior unprovoked venous or arterial thrombosis who are not on stable and adequate anticoagulation.
• * Two or more episodes of herpes zoster, or one or more episodes of disseminated herpes zoster or herpes zoster ophthalmicus.
• * History of malignancy, except for successfully treated non-melanoma skin cancer or localized carcinoma in situ of the cervix.
• * Pregnancy, breastfeeding, or considering becoming pregnant during the study.
• * Clinically relevant or significant ECG abnormalities at Screening.
• * Planned elective surgery that would impact study procedures or assessments through the completion of the Week 52 assessments.
