New shot could tame Sjögren's Flare-Ups
NCT ID NCT06928142
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial tests whether sibeprenlimab, a biologic drug given as a shot every 4 weeks, can reduce disease activity and symptoms in people with Sjögren's disease. About 83 adults with moderate-to-active disease will receive either the drug or a placebo, added to their usual treatments. The study measures changes in disease activity scores and patient-reported symptoms over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sibeprenlimab (a biologic drug given as a shot under the skin every 4 weeks)
- What this could lead to
- If it works, this could point toward a new treatment option to better control Sjögren's disease activity and symptoms.
- What could go wrong
- This is an early Phase 2 trial with only 83 people, so results may not apply to everyone. The drug may not show clear benefit over placebo, and side effects are possible.
