NCT ID NCT07377565

First seen Jun 27, 2026 · Last updated Jul 29, 2026 · Updated 4 times

Summary

This early study tests a single oral dose of HB-2121 in 20 adults with suspected celiac disease. The dye is given four hours before a standard endoscopy to see how it interacts with the small intestine and whether it is safe. Researchers will track side effects and measure the dye's brightness in biopsy samples for up to 30 days.

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

Active substance
HB-2121
What this could lead to
If successful, HB-2121 could become a new diagnostic tool to help doctors identify celiac disease more easily during routine endoscopy.
What could go wrong
This is a very early Phase 1 safety study with only 20 participants. It is not designed to prove the diagnostic works, only that it is safe. Many early-stage trials do not lead to approved tests.
