About the Investigational Study Drug

VIB4920 is a bioengineered protein that works by blocking CD40L and preventing immune cells from attacking one’s own body, including the kidneys. VIB4920 was found to be safe, tolerable, and effective in an early phase trial in rheumatoid arthritis patients, and it is currently being used in other trials. VIB4920 is considered an experimental treatment because it has not been approved for use in lupus nephritis or other diseases.

Participating in VIBRANT

Eligible participants will:

• Receive standard IV methylprednisolone and oral mycophenolate mofetil (MMF) therapy for LN.

• Take prednisone and rapidly decrease the dose during the first 8 weeks of the study.

• Have study visits at Weeks 4 and 8. At Week 8, participants will be evaluated to see how well they are responding to treatment. Participants who have responded well to treatment will leave the study and return to their rheumatologist or nephrologist for ongoing treatment. Participants who have not responded well will be assigned to treatment with either VIB4920 (2/3 of participants) or placebo (1/3 of participants).

• Participants assigned to treatment with VIB4920 or placebo will:
