Experimental K9 pill tested for thyroid eye disease – but study stopped early
NCT ID NCT06467435
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tested an oral drug called K9 (kamuvudine-9) in people with thyroid eye disease, a condition that causes eye bulging and discomfort. The study planned to enroll up to 10 patients but was terminated after only 4 participants. The main goal was to check safety, not to prove the drug works.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Kamuvudine-9 (K9) tablets
What this could lead to
If it works, this could point toward a new oral treatment to control thyroid eye disease symptoms.
What could go wrong
This was a very small, early-phase safety study that was terminated early, so we have little data on effectiveness. The results may not apply to a larger population.
