Brief summary

The purpose of this study is to evaluate the efficacy of ustekinumab in participants with active systemic lupus erythematosus (SLE) who have not adequately responded to one or more standard of care treatments.

Detailed description

This study evaluates the efficacy, safety, and tolerability of ustekinumab in participants with active SLE according to Systemic Lupus International Collaborating Clinics (SLICC) criteria Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score greater than (\>=) 6, despite receiving one or more standard-of-care treatments (example, immunomodulators, antimalarial drugs, and/or glucocorticoids). The total duration of the study is up to 182 weeks, consisting of 3 study periods: a screening period (approximately 6 weeks), a double blind period (52 weeks), and an extension period (124 weeks). Other study evaluations will include pharmacokinetics, immunogenicity, biomarkers and pharmacogenomic evaluations. The safety of the participants enrolled in the study will be monitored on an ongoing basis throughout the study.

Interventions

DRUGPlacebo

Participants will receive placebo matching to ustekinumab IV or SC.

Participants will receive ustekinumab approximately 6 mg/kg via IV route based on body weight-range.
