Study of VIB7734 for the Treatment of Moderate to Severely Active SLE
Purpose

SLEDAI-2K total score ≥ 6 at Screening, excluding fever, SLE headache, or organic brain syndrome. 2. SLEDAI-2K total score ≥ 4, excluding points attributable to any urine or laboratory results, immunologic measures, fever, SLE headache, or organic brain syndrome at Screening and Baseline (Day 1). 3. At least one of the following BILAG 2004 Index levels of disease at Screening: - BILAG A disease in ≥ 1 organ system - BILAG B disease in ≥ 2 organ systems d. PGA score ≥ 1 on a 0 to 3 visual analog scale (VAS) at Screening Have at least one of the following at Screening per central lab: - ANA ≥ 1:80 - Anti-dsDNA antibodies elevated to above normal range as established by the central laboratory (ie, positive results) - Anti-Smith antibodies elevated to above normal (ie, positive results) Ongoing treatment for SLE 1. Treatment with one or more disease-modifying anti-rheumatic drug (DMARD) or immunosuppressive medication: Any of the following medications each administered at conventional anti-rheumatic doses for treatment of SLE for at least 12 weeks before Screening (unless discontinued or dose adjusted for documented drug-related toxicity or size/weight), and at a stable dose (including route of administration) for a minimum of 8 weeks prior to Screening and maintained through Baseline (Day 1): 2. Treatment with OGC monotherapy (without the concomitant use of DMARDs or immunosuppressants): - Average daily dose of PO prednisone ≥ 10 mg but ≤ 40 mg (or prednisone equivalent) for a minimum of 4 weeks prior to Screening and a stable dose for minimum of 2 weeks prior to Screening. The dose of OGC must be kept for a minimum of 2 weeks prior to Randomization. Daily dosing or alternate day dosing of PO prednisone or equivalent is allowed. - Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test at Randomization. - Non-sterilized male participants who are sexually active with a woman partner of childbearing potential must agree to use a condom with spermicide from Randomization and until 3 months (approximately 5 half-lives) after receipt of the last dose.
Exclusion Criteria
