A Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of JNJ-56022473 in Subjects With Systemic Lupus Erythematosus

A Phase 1b, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of JNJ-56022473 in Subjects With Systemic Lupus Erythematosus

The purpose of this study is to assess the safety and tolerability of JNJ-56022473 following multiple subcutaneous (SC) study agent administrations in subjects with Systemic Lupus Erythematosus (SLE) and to determine whether premedication with corticosteroids is required to improve the tolerability of SC JNJ-56022473.

Inclusion Criteria:

• Subject must have a body weight in the range of 40 to 100 kilogram (kg), inclusive, and have a body mass index (BMI) of 18 to 32 kilogram per meter square (kg/m^2), inclusive, at screening

• Have a positive gene signature score during screening, prior to first administration of study agent

• Subjects using allowed pre-existing lupus treatments, if stable for at least 6 weeks prior to the first dose of study medication:

  1. oral corticosteroids equivalent to an average dose up to or equal to (<=) 10 milligram (mg) of prednisone/day
  2. use of antimalarials (such as chloroquine or hydroxychloroguine) for at least 8 weeks
  3. maximum of 1 non-corticosteroid immunosuppressive drug

Exclusion Criteria:

• Subject with history or suspected occurrence of drug-induced systemic lupus erythematosus (SLE)

• Major surgery prior to, and, if planned, during and shortly after the study is not eligible
• Subject has or has had an acute illness, including a common cold, within 2 weeks prior to the study agent administration or has had a major illness or hospitalization within 4 months prior to the screening visit
• Any other inflammatory diseases that might confound the evaluations of efficacy are excluded
