New hope for Behcet's patients: drug TA-650 targets tough lesions
NCT ID NCT01532570
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested the drug TA-650 (infliximab) in 18 people with Behcet's disease who had hard-to-treat lesions. The drug was given by IV every few weeks for nearly a year. The goal was to see if symptoms and signs of inflammation could be completely controlled. The trial is complete, but results are not yet widely available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TA-650 (infliximab, a biologic drug that blocks inflammation)
- What this could lead to
- If it works, this could point toward a treatment option for people with Behcet's disease who have severe lesions not helped by standard therapies.
- What could go wrong
- This is a small, completed Phase 3 trial with only 18 participants, so results may not apply to everyone. The drug is already approved for other conditions, but its benefits for Behcet's special lesions remain uncertain.
