Summary

This early-stage trial tests an investigational drug called ABBV-319 in 36 adults with lupus or Sjogren's disease. The drug is designed to deplete overactive B cells, which are part of the immune system that cause inflammation and symptoms. Participants receive two doses by IV, 21 days apart, and are monitored for safety, side effects, and how the drug moves through the body.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ABBV-319
What this could lead to
If it works, this could point toward a new treatment option for lupus and Sjogren's disease by reducing harmful immune cells.
What could go wrong
This is a very early Phase 1 trial with only 36 people, so it's mainly checking safety and dosing. It may not improve symptoms, and side effects are unknown.
