NCT ID NCT06484855

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-stage trial tests an experimental drug called IBI355 in 30 adults with primary Sjögren's syndrome, an autoimmune disease that causes dry eyes and mouth. The main goal is to check the drug's safety and how the body processes it at different doses. Participants receive either IBI355 or a placebo by IV every 4 weeks.

What this could mean

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

Active substance

IBI355 (an experimental drug given by IV infusion every 4 weeks)

What this could lead to

If successful, this could point toward a new treatment option to control Sjögren's syndrome symptoms and disease activity.

What could go wrong

This is a very early Phase 1 trial with only 30 participants, so it is primarily checking safety and dosing—not yet testing if the drug actually works. Many drugs fail at this stage.
