• • are anti-dsDNA positive (≥ 30 IU/mL) at baseline, OR

• • receipt of any B cell target therapy at any time
• • receipt of an investigational agent within 60 days prior to Day 0 for non-biologics and within 1 year for biologics
• • receipt of abatacept (within 1 year), intravenous (IV) cyclophosphamide (within 6 months), anti-tumor necrosis factor (anti-TNF) therapy, anakinra, IV immunoglobulin (IVIG), prednisone \> 100 mg/day, or plasmapheresis within 3 months, or live vaccine within 1 month.
